Three-phase AC switch

High voltage isolation switches are important switching devices in the electrical systems of power plants and substations, which need to be used in conjunction with high-voltage circuit breakers. The isolation switch is suitable for indoor devices with three-phase AC 50Hz and rated voltage of 12KV. Used to connect, cut off, or convert circuits of high-voltage equipment under voltage and load conditions. Its main function is to ensure the safety of high-voltage electrical appliances and devices during maintenance work, and to isolate voltage. It cannot be used to cut off, input load current, or break short-circuit current. It can only be used for certain switching operations that do not generate strong arcs, which means it does not have arc extinguishing function; According to different installation locations, it can be divided into indoor and outdoor types. According to the number of insulation pillars, it can be divided into single column, double column, and three column types. Each voltage level has optional equipment.
