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.
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;
The performance is stable; there are two fractures inside the switch (isolation knife gate, vacuum interrupter), which meets the requirements of the safety operation regulations of the power sector and greatly increases the safety of the switch; the main circuit and operating mechanism of the switch are sealed in SF6 The gas is the medium in the box, so it is not affected by the environmental conditions and can be maintenance-free.
Strong compatibility; can be equipped with various built-in core-type current transformers for measurement and protection and metering; high-grade, fully-sealed aviation plug design, with high-reliability distribution automation interface.
The structure design is reasonable and the installation method is flexible. It can be hoisted on a column or mounted on a seat; it can be operated by electric or manual operation, making the switch operation more flexible. Its electromagnetic operating mechanism can be closed when there is electricity, and the power consumption can be saved when the electricity is maintained;
