Vacuum load-break switch CKWF-12

ACthree-phasehigh-voltage

CKWF-12 outdoor intelligent vacuum load switch (referred to as load switch) is a new product developed by Zhuhai Comking Electric Co., Ltd. on the basis of researching the performance of similar products at home and abroad. Used on three-phase AC 50Hz, voltage 3~12kV distribution lines, with automatic and manual operation functions. The load switch is installed together with the SPS power transformer and CWFC-1 intelligent controller. In the 3~12kV power supply grid, it can realize automatic fault diagnosis of the power grid, automatic isolation of fault sections, and automatic recovery of power supply in non-fault sections without the need for communication lines. , It can also be connected with the communication system, and realize the automation of telemetry and computer control through the control unit of the sub-station and the main station. Improve the reliability and automation level of power supply in an all-round way. CKWF-12 type outdoor intelligent vacuum load switch is suitable for substations/industrial and mining enterprises and automatic distribution networks of urban and rural power grids and places with frequent operations. features Safe and reliable; the switch adopts vacuum arc extinguishing and zero gauge pressure SF6 gas insulation, which improves the breaking performance of the switch and the insulation and corrosion resistance of internal components; arc extinguishing and insulating medium are oil-free medium, even if an accidental internal fault occurs , and there will be no leakage and escape of high-temperature gas or splashes;
