Distribution transformer JSQXFH-110 series

drysubstationthree-phase

The products are used in SF6 closed combined electrical apparatus of which no need of demolition in overhaul or test, the center conductor of basin type insulator can realize the disconnect and closure to implement body. The GIS do not need add isolating switch device in front of voltage transformer and save the cost. The seal between base and connecting rod adopts skeleton oil sealing and o-shape sealing ring, can assure the product do not leak. Manual operation connecting rod, drive umbrella type insulated part sliding along the pipe run, then realize the disconnect and closure between the center conductor of basin type insulator and the body of primary winding, the operating mechanism device is convenient lighter and high reliability. Basin type insulator center conductor and the product body high voltage electrode using dual spring contactor structure, which can guarantee the reliability of electrical connections.
