This series of high-voltage disconnector is a new type of switch designed by our factory according to the current national and international standards for a series of problems existing in the original GW4 switch. The switch itself is equipped with a grounding switch, which can effectively prevent misoperation such as "hanging ground wire with electricity and closing with ground wire", and the operator does not have to connect with another grounding wire. The switch can be flexibly configured with single-sided grounding, double-sided grounding, manual mechanism, electric mechanism, integrated installation arrester, the switch comes with mechanical locking to prevent misoperation, and can be equipped with electromagnetic locks to realize the interlocking between the main knife switch and the ground knife, the isolation switch and the circuit breaker, which is widely used in photovoltaic, wind power stations, substations, SVG static var generator supporting equipment. The product has excellent electrical and mechanical properties, and is an updated product of the current 10-35KV outdoor switch. This series of products can add our company's "one health control" function of optical sensors, to achieve the power station unattended and one health control position double confirmation function.
