Usually in front of the installation of a circuit breaker dihedral group isolation switch, are intended to isolate the circuit breaker and power, to form a clear break point; because the original circuit breaker is used in oil circuit breakers, oil circuit breakers require frequent maintenance, Therefore, we must have clear sides break point, in order to facilitate maintenance; under normal circumstances, outlet cabinet is powered down from above Zhenjiang bus isolation switch through switchgear, circuit breakers in front of a group of isolation switch is required to be isolated from the power supply Wuxi isolation switch, but sometimes also have to call back breaker may isolating switch, such as the anti-feeding loop by other anti-send, capacitors and other devices, so the back of the circuit breaker switch also requires a set of isolation. Fracture of porcelain must be a comprehensive way, we must first ensure the overall structure of the isolation switch, followed by manufacturing enterprises should strengthen porcelain choice, you can specify the isolation switch manufacturers use superior quality, reputable manufacturers of porcelain products. Also Yangzhou isolation switch, can be carried out NDT techniques, regular porcelain testing. Operating personnel to strengthen surveillance, particularly the observation of porcelain veneer surfaces. To the right way when you run the operation, such as when operating difficulties should not force operations. Wuxi disconnectors, Huayi Electric Power (certified), isolating switch is provided by Xian Huayi power plant.
