ZN85-40.5 33kV Indoor Vacuum Circuit Breaker
ZN85-40.5/T2000-31.5 type indoor high voltage vacuum circuit breaker (hereinafter
referred to as circuit breaker), suitable for three-phase AC 50Hz, rated voltage 40.5kV
power system, can be used for industrial and mining enterprises, power plant and
substation as opening and closing load current, overload current, fault current use.
Circuit breaker and operating mechanism adapt the upper and lower arrangement of
institutions, effectively reducing the circuit breaker depth.
Three-phase arc extinguishing chamber and associative charged body is isolated by
three independent epoxy resin insulating cylinder, composite insulating structure,
circuit breaker meet under normal operating conditions the air distance and the
creepage distance requirements, and effectively reduces the volume of circuit
breaker. The main galvanic circle vacuum interrupter and dynamic and static
conductive connection installed in the insulating cylinder, the phase spacing is only
300mm. Connect of the main circuit electric all adopt the fixed connection, has the
very high reliability. Insulating cylinder is arranged on the upper side of the circuit
breaker frame.
The overall layout is reasonable, beautiful appearance, simple. It has the characters
of small volume, flexible operation, with reliable electrical performance, long service
life, convenient maintenance, maintenance free.
The circuit breaker is suitable for frequent operation and various occasions and
operating conditions are harsh place
1. Altitude: ≤1000m;
2. Air temperature: -15°C ~ +40°C;
3. Relative humidity: daily average is not more than 95%, saturated vapor pressure daily average is not more than 1.8kPa.
4. Earthquake intensity: not more than 8.
5. Installation places: No fire, explosion hazard, serious filthy places.
6. In the second system, the amplitude of induced electromagnetic interference does not exceed 1.6kv
7. Power condition: DC 110V, 220V; AC 110V, 220V
