GW22B Series

Product use and characteristics

GW22B series high voltage AC isolation switch is a three-phase AC frequency 50Hz/60Hz outdoor high voltage transmission and transformation equipment, used to disconnect or connect the high voltage line in the case of no load, in order to convert the high voltage line, change the operation mode, and maintenance of the bus and circuit breaker and other high voltage electrical appliances to implement safe electrical isolation. It can also be divided into a certain value of inductance, capacitance small current, and has the ability to open and close the bus current conversion.

This product is a single-column single-arm vertical telescopic structure, the contact is clamp type, the vertical insulation fracture is formed after opening, suitable for the use of bus isolation switch. It is installed directly under the bus bar and has the advantage of small footprint. Can be equipped with JW10 type ground switch, as the ground of the lower bus, the upper bus grounding need to install an independent ground switch. 363, 550kV isolation switch and ground switch are equipped with SRCJ8 electric mechanism for single-pole operation, and can achieve three-pole electrical linkage. The 126 and 252kV isolation switches are respectively equipped with SRCJ7 and SRCJ3 motor operating mechanism three-pole linkage operation, and the ground switches are respectively equipped with CS11, SRCS manual operating mechanism or SRCJ electric mechanism three-pole linkage operation.
