ZW20A-12 outdoor high voltage vacuum circuit breaker (hereinater caled vacuum circuit breaker is an outdoor power distribution equipment withrated voltage of 12 KV and three-phae AC 50 Hz.It uses vacuum arc extinguishing and SF6 gas as the insulating medium and is an improved producof ZW20-12 type on-column vacuum circuit breaker. The cabinet adopts the gas sealing, explosion-proof and insulation structure technologyintroduced by Japan Toshiba VSp5.The inlet and outlet conduits also have improved seaing performance, and the overal sealing pertormance isexcelent. The SF6 gas filed interaly does not leak and is not affected by environmental impacts;its spring operating mechanism is miniaturized andoptimized for relabllty and stablty. it uses a linear chain main drve and a mult-stage tip system. the reliabiity and stablity ot the spnng are severaltimes hicher than the traditional spring operating mechanism: the contact between the shaft and the sieeve of the main ircuit adopts an adducionand extermal tension type bracelet structure, and the contact resistance ofthe main circuit is small and the temperature rise is low. Therefore,ZW20A-12 outdoor on-column vacuum circuit breaker is a maintenance-free product, which is the best among the on-column circuit breakers.
