ZW20 Series Vacuum Circuit Breaker
ZW20-12F series outdoor high-voltage AC boundary vacuum circuit breaker (hereinafter referred to as "Boundary circuit breaker") is an outdoor high-voltage switchgear with three-phase AC 50Hz and a rated voltage of 12kV.
It is mainly composed of a vacuum circuit breaker body, distribution automation feeder terminal, voltage transformer, control cable, etc. The circuit breaker body is equipped with a vacuum arc extinguishing chamber, current transformer, zero sequence current transformer, and other components.
Datasheet for the ZW20 Vacuum Circuit Breaker
Technical parameter
1. Matching with smart grid: It can realize three-stage protection, zero-sequence grounding protection, reclosing and remote communication functions.
2. Flexible and convenient operation: it can store electric energy, open and close electrically, or store energy manually, open and close manually, and can operate at close range.
3. Low operating power and high reliability: The operating power (about 30W) of the newly designed miniaturized spring operating mechanism is reduced to the lowest level.
4. Reliable sealing performance: SF6 gas pressure is zero gauge pressure, and mature sealing structure technology is adopted, which has reliable sealing performance and is not easy to leak.
5. Unique way of entering and exiting: Uses silicone rubber sleeve, the insulation distance between the terminals is sufficient, and the external insulation performance is excellent.
6. Excellent safety performance: There is an explosion-proof device on the top of the box, even if there is an internal failure, there will be no leakage of high-temperature gas or splashes.
7. Flexible installation method: it can be installed on the pole or by sitting.
8. The rated current is large, up to 1250A, and the breaking capacity is strong, up to 25kA.Datasheet for the ZW20 Vacuum Circuit Breaker
