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 Yinchuan outdoor high-voltage isolation switch, so there are obviously two sides should break point, in order to facilitate maintenance; under normal circumstances, outlet cabinet is bus powered down from above Hohhot outdoor high-voltage isolation switch through switchgear, circuit breakers in front of a group of isolation required switch to isolate the power isolation switch, but sometimes also have to call back breaker may, for example, by Reverse Reverse Wuhai outdoor high-voltage isolation switches, capacitors and other devices of the other loop, it also needs to back breaker a group of isolation switch. Isolation switch is not in place together how to deal with? A: The isolation switch is closed in place, most of the corrosion mechanism, jam, causing not adjusted overhaul debugging and other reasons, this happens, you can pull the isolation switch and then closing. For 220KV isolation switch, push rods insulation available, if necessary apply power handling. High voltage isolation switch should overhaul 1-2 times every two years. Qinghai outdoor high-voltage isolation switch, isolation switch, the power provided by the Xi'an Huayi Huayi power plant. Xian Huayi power plant (www.xahy.com) strong, credible, in Xi'an high-voltage circuit breakers and other industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Huayi power and you hand into the brilliant, for a better future!
