Outdoor Vacuum Load Break Switch
Description
Outdoor vacuum load break switch is an outdoor power distribution equipment with rated voltage of 12KV and three-phase AC 50HZ. It is mainly used for breaking and closing the load current, overload current and short-circuit current in the power system. It is suitable for protection and control in power distribution systems of substations and miners. It is more suitable for rural power grids and frequently operated places, especially for the needs of urban network and rural network transformation. It has the advantages of small size, light weight, suitable for frequent operation, no need maintenance when arc interrupting, and it is widely used in the distribution network.
This product is a new intelligent switch composed of circuit breaker and intelligent controller. It can be used as recloser, sectionalizer and circuit breaker, and is widely used in variable power distribution lines. It can be used independently for small and medium-sized substations and substations, reducing floor space, saving investment and improving power supply reliability.
In conjunction with other switching devices, the product automatically cuts off and isolates faults, automatically transfers power, and automatically restores power. Through the connection between the telecontrol device and the main control room DCS system, the product can realize four remote functions such as remote control, remote signaling, telemetry and remote adjustment, and realize distribution automation.
