ZW20-12F series outdoor high-voltage AC boundary vacuum circuit breaker
ZW20-12F/T ☐ - ☐ series outdoor high-voltage vacuum circuit breakers (hereinafter referred to as circuit breakers) are outdoor power distribution equipment with a rated voltage of 12kV and three-phase AC 50Hz. It uses vacuum arc extinguishing and SF6 gas as insulation medium, and is an improved product of ZW20-12F column mounted vacuum circuit breaker. The box adopts the gas sealing, explosion-proof and insulation structure technology of VSP5 from Toshiba, Japan. The inlet and outlet conduits have also been improved in sealing performance. The overall sealing performance is excellent. The SF6 gas filled inside does not leak and is not affected by the individual environment; Its spring operating mechanism has been miniaturized and optimized for reliability and stability. With the direct chain main drive and multi-stage tripping system, its action reliability and stability are several times higher than the traditional spring operating mechanism in China; The contact between the shaft and the sleeve of the main circuit adopts the internal retraction and external tension watch chain structure, so the contact resistance of the main circuit is small and the temperature rise is low. Therefore, ZW20-12F outdoor pole mounted vacuum circuit breaker is a maintenance free product and a good product among pole mounted circuit breakers.
