SVR-12 solid insulation vacuum ring net cabinet (compact switchgear)
General introduction
SVR-12-type insulated vacuum ring network cabinet is my company based on the development of smart grid needs newly developed new medium voltage switchgear. The series of products will switch units and a diversion circuit through the integration of epoxy molding, each ring unit has a three-phase unit, through the full insulation busbar connection, all the first conductive parts are body seal, especially the need to charge SF6 gas.
Ring counter can be configured with three-phase linkage type permanent magnet mechanism or spring mechanism integrated intelligent control and protection unit, which can quickly cut off the fault current and isolate the fault. It has the automation interface of distribution network to meet the requirements of smart grid.
Substation 10kV outlet interval for power system, power distribution switchgear, user demarcation ring counter, user substation, ring switch station, district, road, government, hospital, petrochemical, metallurgy, mining, etc.
