Wortai ZW****2 outdoor demarcation vacuum circuit breaker (hereinafter referred to as the circuit breaker) is an outdoor power distribution device with a rated voltage of *2kV and a three-phase AC *0Hz. It uses vacuum arc extinguishing and SF6 gas as the insulating medium. The box adopts the gas sealing, explosion-proof and insulating structure technology imported from Toshiba VSP5. The inlet and outlet conduits have also been improved in sealing performance, and the overall sealing performance is excellent. The internal filling of SF6 gas Does not leak and is not affected by the external environment. The spring operating mechanism has been miniaturized design and optimized for reliability and stability. It adopts a linear chain drive and a multi-stage tripping system, and its operational reliability and stability are significantly improved compared to traditional domestic mechanisms. The contact between the shaft and the sleeve of the main circuit adopts a retractable watch chain structure, which has low contact resistance and low temperature rise. Therefore, the ZW****2 outdoor demarcation vacuum circuit breaker is a maintenance-free product and the best product among the pole-mounted circuit breakers.
