How to extend the service life of the inverter

The frequency converter still has some unsatisfactory places under different operating conditions, resulting in a shortened service life and a corresponding increase in the workload of installation, commissioning, daily maintenance and repair of ancillary equipment, which has caused significant direct and Indirect economic loss. Now the application environment of the inverter, electromagnetic interference and anti-interference, power grid quality and other aspects are analyzed, and the problems that should be paid attention to when using the inverter and the corresponding improvement suggestions are proposed.

I believe this will have a significant impact on increasing the service life of the inverter effect. 1. The influence of electromagnetic interference on the inverter In modern industrial control systems, computer or PLC control technology is mostly used. In the process of system design or transformation, attention must be paid to the interference of the inverter on the computer control board. The inverter is subject to external interference sources. Due to the poor general technology level of the microcomputer control board designed by the user, it does not comply with EMC international standards. After the inverter is used, the conducted and radiated interference often causes the control system to work abnormally.

Describe the necessary measures.

1) Good grounding. The ground wire of the strong electric control system such as the motor must be reliably grounded through the ground bus, and the shielding ground of the microcomputer control board should be grounded separately. For some occasions with severe interference, it is recommended to connect the sensor and I / 0 interface shield to the control ground of the control board.

2) Adding EMI filter, common mode inductance, high frequency magnetic ring, etc. to the input power of the microcomputer control board can effectively suppress conducted interference. In addition, when the radiation interference is serious, such as when there is a GSM or PHS base station around, you can add a metal mesh shield to the microcomputer control board to shield it.

3) Installing an EMI filter on the input end of the inverter can effectively suppress the conduction interference of the inverter to the power grid, and installing input AC and DC reactors can improve the power factor, reduce harmonic pollution, and have a good overall effect. In some occasions where the distance between the motor and the inverter exceeds 100 m, it is necessary to add an AC output reactor on the inverter side to solve the leakage current protection caused by the distribution parameters of the output wire to the ground and reduce the external radiation interference. An effective method is to use steel pipe threading or shielded cable, and connect the steel pipe shell or cable shield to the ground reliably. It is worth noting that when the AC output reactor is not added, if the method of steel pipe threading or shielded cable is used, the distributed capacitance of the output to ground is increased, and overcurrent is prone to occur. Of course, in practice, one or more of these methods are generally adopted.

4) Electrically shield and isolate the analog sensor detection input and analog control signals. In the design process of the control system composed of frequency converters, it is recommended not to use analog control as much as possible, especially when the control distance is greater than 1m and it is installed across the control cabinet. Because the inverter generally has multi-stage speed setting and switching frequency input and output, it can meet the requirements. If it is necessary to use analog control, it is recommended to use shielded cable and achieve a remote grounding on the sensor side or the inverter side. If the interference is still serious, DC / DC isolation measures need to be implemented. You can use standard DC / DC modules, or use optical isolation for v / f conversion, and then use the frequency setting input method.

2. The impact of the working environment In the actual application of frequency converters, most of the domestic customers, except for a few dedicated machine rooms, install the frequency converter directly on the industrial site in order to reduce costs. The work site generally has problems with large dust, high temperature, and high humidity, as well as metal dust and corrosive gases in the aluminum industry. Therefore, it is necessary to make corresponding countermeasures according to the site conditions.

1) The inverter should be installed inside the control cabinet.

2) The inverter is best installed in the middle of the control cabinet; the inverter should be installed vertically, and the large components that may block the exhaust and intake air should be avoided directly above and below the inverter.

3) The minimum distance between the upper and lower edges of the inverter and the top, bottom, or partitions of the control cabinet, or large components that must be installed, should be greater than 300 mm.

4) If a special user needs to remove the keyboard during use, the keyboard hole of the inverter panel must be strictly sealed with tape or replaced with a dummy panel to prevent a large amount of dust from entering the inverter.

5) When using the inverter in a place with many dusts, especially a place with multiple metal dusts and flocs, the overall requirement of the control cabinet is to be sealed, and the air inlet and air outlet are specially designed for ventilation; the top of the control cabinet should have a protective net and protective roof Cover the air outlet; the bottom of the control cabinet should have a bottom plate, air inlets, and wire holes, and install a dust filter.

6) Most of the printed boards and metal structural parts inside the inverter manufacturers have not been specially treated to prevent moisture and mildew. If the inverter is in a harsh working environment for a long time, the metal structural parts are prone to rust. The conductive copper bar will be more corroded during high temperature operation. Corrosion will cause damage to the small copper wires on the computer control board and drive power board. Therefore, for applications that are wet and contain corrosive gases, the internal design of the inverter used must have basic requirements, for example, the printed circuit board must be sprayed with three anti-paints, and the structural parts must be treated with nickel-chromium plating. Craftsmanship. In addition, other positive, effective, and reasonable measures against moisture and corrosion gases are required.

3. The influence of grid quality on the inverter In the case of impact loads such as welding machines, electric arc furnaces, rolling mills, etc., the voltage often flickers; in a workshop, when there are multiple frequency converters and other capacitive rectifying loads working, the harmonics generated by them are very important for the quality of the grid Severe pollution can also cause considerable damage to the equipment itself, ranging from the inability to operate continuously and the damage to the input circuit of the equipment. The following measures can be taken.

1) In the impact load such as electric welding machine, electric arc furnace, rolling mill and other occasions, it is recommended that users add reactive static compensation devices to improve the power factor and quality of the power grid.

2) In workshops where inverters are concentrated, it is recommended to use centralized rectification and DC common bus power supply. It is recommended that users use the 12-pulse rectification mode. The advantage is that the harmonics are small and energy-saving, especially suitable for frequent starting and braking, and the motor is in the occasion of both electric operation and power generation operation.

3) Passive LC filter is installed on the input side of the inverter to reduce input harmonics, improve power factor, high reliability and good effect.

4) The source PFC device is added on the input side of the inverter, which has the best effect but the cost is higher.

4. Conclusion: Starting from the problems that occur in the actual application system of the inverter, from the aspects of external factors such as interference, use environment, power grid quality, etc., the impact of the adverse factors on the inverter in the actual application is proposed, and then the problem is summarized Some methods of solving problems and suggestions for improvement can play a very good role in extending the service life of the inverter, and have certain reference value in the application of actual projects.

4) Electrically shield and isolate the analog sensor detection input and analog control signals. In the design process of the control system composed of frequency converters, it is recommended not to use analog control as much as possible, especially when the control distance is greater than 1m and it is installed across the control cabinet. Because the inverter generally has multi-stage speed setting and switching frequency input and output, it can meet the requirements. If it is necessary to use analog control, it is recommended to use shielded cable and achieve a remote grounding on the sensor side or the inverter side. If the interference is still serious, DC / DC isolation measures need to be implemented. You can use standard DC / DC modules, or use optical isolation for v / f conversion, and then use the frequency setting input method.

2. The impact of the working environment In the actual application of frequency converters, most of the domestic customers, except for a few dedicated machine rooms, install the frequency converter directly on the industrial site in order to reduce costs. The work site generally has problems with large dust, high temperature, and high humidity, as well as metal dust and corrosive gases in the aluminum industry. Therefore, it is necessary to make corresponding countermeasures according to the site conditions.

1) The inverter should be installed inside the control cabinet.

2) The inverter is best installed in the middle of the control cabinet; the inverter should be installed vertically, and the large components that may block the exhaust and intake air should be avoided directly above and below the inverter.

3) The minimum distance between the upper and lower edges of the inverter and the top, bottom, or partitions of the control cabinet, or large components that must be installed, should be greater than 300 mm.

4) If a special user needs to remove the keyboard during use, the keyboard hole of the inverter panel must be strictly sealed with tape or replaced with a dummy panel to prevent a large amount of dust from entering the inverter.

5) When using the inverter in a place with many dusts, especially a place with multiple metal dusts and flocs, the overall requirement of the control cabinet is to be sealed, and the air inlet and air outlet are specially designed for ventilation; the top of the control cabinet should have a protective net and protective roof Cover the air outlet; the bottom of the control cabinet should have a bottom plate, air inlets, and wire holes, and install a dust filter.

6) Most of the printed boards and metal structural parts inside the inverter manufacturers have not been specially treated to prevent moisture and mildew. If the inverter is in a harsh working environment for a long time, the metal structural parts are prone to rust. The conductive copper bar will be more corroded during high temperature operation. Corrosion will cause damage to the small copper wires on the computer control board and drive power board. Therefore, for applications that are wet and contain corrosive gases, the internal design of the inverter used must have basic requirements, for example, the printed circuit board must be sprayed with three anti-paints, and the structural parts must be treated with nickel-chromium plating. Craftsmanship. In addition, other positive, effective, and reasonable measures against moisture and corrosion gases are required.

3. The influence of grid quality on the inverter In the case of impact loads such as welding machines, electric arc furnaces, rolling mills, etc., the voltage often flickers; in a workshop, when there are multiple frequency converters and other capacitive rectifying loads working, the harmonics generated by them are very important for the quality of the grid Severe pollution can also cause considerable damage to the equipment itself, ranging from the inability to operate continuously and the damage to the input circuit of the equipment. The following measures can be taken.

1) In the impact load such as electric welding machine, electric arc furnace, rolling mill and other occasions, it is recommended that users add reactive static compensation devices to improve the power factor and quality of the power grid.

2) In workshops where inverters are concentrated, it is recommended to use centralized rectification and DC common bus power supply. It is recommended that users use the 12-pulse rectification mode. The advantage is that the harmonics are small and energy-saving, especially suitable for frequent starting and braking, and the motor is in the occasion of both electric operation and power generation operation.

3) Passive LC filter is installed on the input side of the inverter to reduce input harmonics, improve power factor, high reliability and good effect.

4) The source PFC device is added on the input side of the inverter, which has the best effect but the cost is higher.

4. Conclusion: Starting from the problems that occur in the actual application system of the inverter, from the aspects of external factors such as interference, use environment, power grid quality, etc., the impact of the adverse factors on the inverter in the actual application is proposed, and then the problem is summarized Some methods of solving problems and suggestions for improvement can play a very good role in extending the service life of the inverter, and have certain reference value in the application of actual projects.

SUB/LIMINAL INSTALLATION

             POSSIBLE TOOLS AND MATERIALS NEEDED

Pencil, notebook, the floor plan of exhibition space and its                               dimensions  step ladder or ladder  a working plug  and a  plug point  A screwdriver, craft knife, pliers and wire stripper (to make a plug)  Make sure electricity is in working order (always have a backup                       plan i.e. a generator)  No nails glue, double-sided tape   An extension cable   A Hammer and nails Electric Drill and  drill bits (with the right drill bits for the job Measuring tape and metal ruler  Spirit meter or level   Clamps Anchors and hooks  Fine-tooth saw ( for possible edge removals) Square clear rubber bumpers  Safety glasses are recommended for eye protection

Before you start, you want to take a good look at the space around you. It is imperative that you take careful consideration of the layout and other factors that will make the installing process smoother and 10 X easier.

Things to consider in the space are

Dimensions and shape of the space – specifically the wall space the position of the entrances and exits Details of the floor and ceiling – their width, strength etc Details of the skirting board Cable specifications– are there plug points etc? Brackets     Ceiling support for any suspended elements Equipment cupboard with access and shelving – to keep the space in order Equipment failure – what spares do you have available if/when this happens? How to rectify this problem 

Now that we understand the exhibition space a bit better it is time to identify the shipping crate in front of us:

WHAT THE SHIPPING CRATE IS MADE OF

Each type of wood has its own unique characteristics and only a certain few will fit the criteria – the shipping crate has to be strong enough to hold the large artwork whilst also being durable to wear and tear during the journey to and from the installation space. Here are few ideas of what the crate could be made of:

· Beech is a hard, strong and heavy wood. It has high shock  resistance

·Oak is very hard wearing and heavy.

 Maple wood is much more durable and heavier. As maple wood is so strong and moisture resistant it is the ideal wood to withstand years of wear and tear. 

 Pine is very affordable and lightweight - It is less durable compared to hardwoods such as maple or oak but can be combined with one of the two kinds of wood to create a stronger shipping crate.

Walnut wood is a hardwood and is known for its strength however hardwoods can be expensive.

 Plywood is a very strong manufactured wood - it is a build-up of layers of wood veneers which are bonded together to create a flat smooth surface. This might be the best option.

 Medium Density Fibreboard is very strong  as it has a strong/ dense structure

 Now that we have an idea of what the crate is made of we need to open it up.    Wooden crates are built to resist punishment so the right tools are needed. A hammer or a crowbar can be used.

   WIRING A PLUG

Since the artwork runs on electricity and we are already made aware that the power cable does not have a plug attached we will have to wire and connect our own. All we need is a screwdriver, pliers and wire strippers to cut the wires to length and to strip away unwanted insulation

 1.   Using the craft knife cut  2cm of the insulation cord in order to expose 3 coloured wires inside (be careful to not cut into them) and then with wire strippers cut 2 cm again to reveal the copper wires within the coloured ones

2.   Make sure to tighten or twist the copper wires to make them straight

3.   Now taking the screwdriver, unscrew the plug cover ( there are 3 screws on each of the plugs pins)

4.   Now that the plug cover is off and you can see inside of the plug you will need to take your 3 coloured wires (with copper exposed)  and place them into the correct locations ( mark them E, N, L to make it easier for yourself)

Green/yellow wire to earth terminal (marked E)

Blue  wire to neutral terminal (marked N)

Brown wire to live terminal (marked L)

5.   Insert your pre-twisted copper wires into these holes: the green/ yellow wire into the top (E), the blue wire into the left ( N), and the brown wire into the right ( L).

6.   Tighten the screws on each pin.

7.   Ensure the electrical cord is firmly gripped by the arrestor clips.

8.   Now re-screw the plug cover

 Once you have wired the plug it is important to double check to see if your connections are in the correct order. Once you are confident of your wiring skills you can now connect your plug to the power cable

                       INSTALLING THE ARTWORK

Important to note:

Size: is 3m by 2,2m

Landscape format

Where: dividing wall in main space

Must be centred and have 50cm gap between piece and the floor

Attached to servo-motors which change angle

 Before we begin the room must be prepared for the task at hand - so safety precautions must be made and space must be created for the tools and materials required. Now that we have taken the necessary precautions, we need to start by using a tape measure and pencil to measure the dimensions of the wall and to mark the spots where the piece will be installed. Then decide where the nails/screws go in relation to where the piece hangs on the wall.

 For the piece to be centred we need to accurately measure the length of the floor to the ceiling, leaving a 50 cm gap between the two.

There needs to be enough space between the wall and the artwork/piece in order to avoid clashing – the servo motors have a rotary actuator that can move from a 90-degree angle to a 180 degree one.  The rotation of the servo motors needs to be taken into consideration. Once we have decided on a safe enough distance from the wall and all the preliminary measurements are in place, we can start to install.

For extra support, with the use of brackets, we can drill the piece into the wall. First, we need to obtain the ladder and some assistance. The use of D-Rings can be used and are screwed to the back of the work – the work can be hung directly from these or a wire can be stretched from one D-Ring to the other. However, the piece will probably be heavy so we will need to add more support. A cleat can be used as this is a large scale heavy work.  Suspension wire from the ceiling could be used as an extra support and to ensure the piece will stay in place and not fall.

 When the piece is hung we can use a level to see whether the piece is centred and straight.  Make sure to remove any pencil markings from the wall. Plug the piece into the power cable and check whether everything in working order.

Solutions to Common Issues About Fiber Optic Cable

It is a common sense that the light of optic transmission can travel much longer distances than normal transmission medium. And that is why fiber optic cable is of popularity than copper cable those years. Apart from the higher bandwidth, its very high performance data working and telecommunications has won the good reputation for itself. As it has been used by more and more Ethernet users, some common problems about fibre cable occur. Then how to solve them? This passage would provide a satisfied answer for you.

Fiber Damage

It is reckless to judge whether the fibers within the cable are broken or damaged just by looking at it through the naked eye. In most cases, the optical fiber damage would not so evident that could be observed by its outer appearance. Under this occasion, a fiber optic tracer can be utilized to trace any faults within the cable. Its operation principle just like a miniature flashlight that uses an LED and can be fitted to the the cable connector for the purpose of checking continuity. If the fibers are all complete and not damaged, you can see the light from the two ends the cable is shone.

Connectors

LC, SC, ST, FC, MPO, MTP...are common connectors of optic cords, and it is paramount to fit correct connectors to the fiber cable. Before you use the fibre cable, you should check each of the connectors to see if they well fitted or not. If not, it is necessary for you to rectify it by inserting them properly. If the issue still happens, you can replace the cable by a cable of spring loaded connectors. In that way, the connectors would fit the cable securely and would not slip out.

Length Problem

Once the a fiber optic cable has redundant length after it has been used for a connection, there are potential risks with the left cable and it would result in permanent damage to the fibers and components within the cable. The potential risks are bending, twisting or winding around the cable itself. Almost every store provides different cable length for meeting the requirement of various length demand, especially the online store, they still offer the service of customizing, and you can get the exact cable length according to your actual demand. Before you look through the online cable store, it is essential for you to get your optimal needing length by using a measuring tape. You can position all the equipment that you intend to connect with the cable, and then measure the distance of them and get the approximate length.

Stretching Problem

If an optical fiber cable being stretched over a range itself, and then the fiber and other components within the cable would be damaged. You can move the cables closer or buy an additional cable with proper length. There is another case would cause stretching. Sometimes, it just occurs when you pulling at the jacket of the cable. You should use the grips at the connectors designed to be used to fit and remove them.

External Damage

It is quite necessary to have a thorough visual inspection of the optical fiber cable from time to time. Because any defects would affect the ability of the cable to work properly and even bring unimaginably consequences. During the inspection, if you find any prominent defect occurs, such as splits or scratches, and then please replace the cable.

Conclusion

It seems that it is an irresistible trend to use optical fiber cables now and future. According to this article, we are cleared that some basic solutions for the some common issues about fibre cables.
