The ZW7-40.5(M)series outdoor high-voltage vacuum circuitbreaker is a three-phase AC 50Hz outdoor high-voltage electricalequipment with a rated voltage of 40.5kV. When equipped with ahigh-voltage permanent magnet actuator, it can achieve on-site andremote fast opening and closing operations. The designperformance meets the requirements of the national standardGB1984-89 “AC High-Voltage Circuit Breakers” and complies withthe requirements oflEC6100-4.1:2000″Electromagneticcompatibility testing and measurement techniques – Generalintroduction on immunity testing “The circuit breaker has a porcelain post structure, with the upperporcelain insulator serving as the arcing chamber, housing thevacuum arcing chamber. The lower porcelain insulator serves as thesupport column, and the three-phase porcelain insulators areinstalled on a common structural box. The moving end of the arcingchamberis connected to the output shaft of the permanent magnetmechanism through a connecting arm and insulating rod. Thepermanent magnet mechanism and the connecting rod of the circuibreaker are housed in a watertight mechanism box. The productconsists mainly of the vacuum arcing chamber, current transformerstransmission mechanism,and spring operating mechanism.
