Product introduction:
ZN85-40.5 indoor high-voltage vacuum circuit breaker is suitable for three-phase AC 50Hz, 40.5kV system. It can be used by industrial and mining enterprises, power plants and substations for switching load current, overload current fault current, and suitable for frequent operation occasions. The circuit breaker adopts an upper and lower arrangement structure, which effectively reduces the depth of the circuit breaker. And adopt the composite insulation structure, the three-phase arc interrupter and the connected live body are separated by three independent epoxy resin insulation shells. After the composite insulation structure is adopted, the circuit breaker meets the air distance and creepage distance requirements under normal operating conditions. , And effectively reduce the volume of the circuit breaker, the main conductive circuit vacuum interrupter and dynamic and static conductive connections are installed in the insulation, so that the phase-to-phase is only 300mm. The main circuit electrical connections are all fixed connections with high reliability.
Normal conditions of use:
Ambient temperature: not higher than +40ºC, not lower than -15ºC;
Air relative humidity: the daily average is not more than 95%, and the monthly average is not more than 90%;
The altitude does not exceed 1000 meters;
Earthquake intensity does not exceed 8;
A place free from fire, explosion, serious pollution, chemical corrosion and severe vibration.
