Product details
summary:
1. The ZW20-22F series outdoor high-voltage vacuum circuit breaker (hereinafter referred to as the circuit breaker) is an outdoor distribution equipment with a rated voltage of 12kV and three-phase AC 50Hz. It adopts vacuum arc extinguishing and SF6 gas as insulation medium, and is an improved product of ZW20-22F column mounted vacuum circuit breaker;
2. The box adopts the gas sealing, explosion-proof, and insulation structure technology introduced from Toshiba VSP5 in Japan. The sealing performance of the inlet and outlet conduits has also been improved, and the overall sealing performance is excellent. The SF6 gas filled inside does not leak and is not affected by the personal environment;
3. The spring operating mechanism has been designed for miniaturization and optimized for reliability and stability. It adopts a direct acting chain main transmission and a multi-stage trip system, which improves the reliability and stability of the action by several times compared to traditional spring operating mechanisms in China;
4. The contact between the shaft and the sleeve of the main circuit adopts an inward and outward tension type watch chain structure, which has low contact resistance and low temperature rise in the main circuit. So, the Z W20-12F outdoor pole mounted vacuum circuit breaker is a maintenance free product and a great choice among pole mounted circuit breakers.
5. ZW20-22F has added overcurrent protection and mechanism spring energy storage indication compared to ZW20-22, and is equipped with an aviation socket for secondary electrical connection, making it easy to integrate with intelligent controllers;
6. The excellent electrical and mechanical performance has led to the widespread application of ZW20-22F outdoor column mounted vacuum circuit breakers;
7. Mainly used for breaking and closing load current and short-circuit current of 10kV power systems, suitable for protection and control in substations and industrial and mining enterprise distribution systems, and more suitable for places with frequent operation of the power grid;
8. This product is compatible with the controller and has excellent recloser function, which can meet the requirements of distribution automation systems.
