Can meet the requirements of various types of power plants, substations and industrial and mining enterprises .
This switchgear compliance with standard GB3906 << 3 ~ 35kV AC metal closed switchgear>> ,
IEC298 << Rated voltage between 1KV and 52KV AC metal closed switchgear and controlgear >>
And DU/T402 , DL/T404 .
Structure Characteristic
XGN-12 is the metal enclosed structure switchgear , The cabinet frame is welded from angle iron ,
There are the circuit breaker room , busbar room, relay room , separate by steel board .
The circuit breaker room at front side and bottom of cabinet body , The rotating pull lever of the circuit breaker is connected to the operating mechanism , The top connecting terminal connect with the top isolator switch, the bottom connecting terminal of circuit breaker contact with the current transformer , The current transformer contact with the wiring terminal of bottom isolator switch. The circuit breaker room also has a pressure relief channel ,the gas can be released through the exhaust channel if the internal electric arc occurs .
The busbar room at the top backside of cabinet , in order to reduce the height of the cabinet, the busbar arranged . Support by the bending strength 7350N porcelain insulator . The busbar connect with the wiring terminal of top isolator switch. The adjacent busbar rooms can be isolated .
The cable room at the bottom backside , can equip the voltage monitoring device , the cable fixed on bracket , this room can be the contact cable room as it is the contact scheme . The relay room at the top foreside , the installation board can install kinds of the relay, there are the terminal row bracket , can install the indicated instrument and signal elements at the door , can arrane the secondary small busbar at the top .
The mechanical interlock used to prevent the operate the isolator switch on load , incorrect operate the circuit breaker , prevent entry to the electric live space , isolator switch with earthing close .

Product Overview
TBB-10 high voltage reactive power automatic compensation device suitable for the 220KV,110KV,35KV substation , 10KV (6KV) busbar reactive automatic tracking compensation . Mainly used in the AC power frequency which is large load fluctuations , usually cause the situation of over or less compensation . This device can do the real time detection for reactive power . Then compare to the set values . Conduct automatic intelligent cutting operation . Make the reactive to dynamic balance , improve the power factor of system . Stabilize the system voltage, reduce the loss and save the electricity cost .
Structure Characteristic
It has the ZKG and ZGKN controller , through tracking the fuse automatically and control the main transformer , control the power factor and the system voltage within the set range ， can automatically identify the various operation modes of double main transformer substation , by the long distance automatic selector switch. Can select various working methods of pressure adjustment and compensation flexible .
Automatic recognition voltage regulating switch gear information one by one by BCD code , There are also the functions of double main transformer synchronization adjustment ,sliding gear , gas alarm .
Harmonic measurement display function ,can measurement and show low voltage side current high harmonic content .
With the function of high voltage, low voltage, break line, mechanistic breakdown , overflow of main transformer .
Equip with the RS-485 and RS-232 high-speed data communication interface , match the substation comprehensive automatic system .
