Full Air-Insulated Medium Voltage 12kV Switchgear

Full air insulation medium voltage switchgear is 3.6-12kV, three phase AC 50Hz, packaged power distribution unit for single bus bar and single bus bar section system. Mainly used for power transmission of power plant,  medium or small scale generator, power distribution for industrial and mining enterprises and institutions, as well as power acceptance and transmission of secondary substation and large scale voltage electromotor starting, so as to perform control protection and monitoring. This switchgear compiles with IEC298 and GB3906-91 etc standards. In addition to work with domestically produced Model Vh3 vacuum circuit breaker and VHCR series of vacuum contactors provided, it may also work with Siemens Model 3AH5 vacuum circuit breaker, and is really a power distribution with superior performance.

Structure of cabinet body:
The switchgear is cladding type metal enclosed structure, consists of cabinet body
and with drawable part (midship handcart). Cabinet body is divided into handcart
room, main bus bar room, cable vault and relay instrument room. Three high voltage
compartments have pressure release passages and release ports respectively,
so that internal troubleshooting could be released only through release port
in case of failure, titus prevent fire pooling accident and protect personal
satiety. Passed this test.
