GW23B Series

Product use and characteristics

GW23B series isolation switching current is a three-phase AC frequency 50Hz/60Hz outdoor high-voltage power transmission and transformation equipment, used to disconnect or connect high-voltage lines in the case of no load, in order to convert high-voltage lines, 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 split a certain value of inductance, capacitance small current and has the ability to switch the bus current.

This product is a double column straight retractable structure, the contact is inserted, and the horizontal insulation fracture is formed after opening, which is suitable for 110kV and 500kV substations as line isolation switch. JW10 ground switch can be attached to one side or both sides. When two groups of GW23B isolation switch are combined into a common static contact form, it is suitable for one-and-a-half times connection, which can save the floor area of the substation. 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 and SRCS human operating mechanism three-pole linkage operation.
