Take you into the world of switch components
Disconnecting switch: (what we call the isolating switch, generally refers to the high pressure isolating switch, the rated voltage in above 1 kv and isolating switch) high voltage switch to use a kind of most electrical appliances, isolation effect in the circuit, its working principle and structure is simple, but, because of the large amount work reliability requirement is high, It has great influence on the design, establishment and safe operation of substation and power plant.
