Mechanism na yi haɗa a cikin GHK-J12 environmental protection cabinet yana da GHK-J12 circuit breaker reclosing spring operating mechanism, kuma isolator part yana da RNHSG-07 compression spring isolation operating mechanism. Isolator machinery yana cikin ɗan yanayi, kuma V operating mechanism yana cikin ɗan yanaye. Yana amfani da single rod mechanical structure don in samun interlocking da lower door. Ba zan iya buƙatar lower door ba tare da lokacin da main circuit yana cikin open state da kuma tare da ground reliable. Overall structure of the mechanism yana da compact, kuma operation interlocking yana ci gaba da wata requirements. Operating mechanism yana ci gaba da relevant requirements of standards such as GB1984-2014, GB/T1022-2020, GB3804-2017, GB3906-2020, etc.
Operation of opening and closing the mechanism
Power transmission operation:
①. Close the door; ②. Insert the handle into the grounding operation hole of the G mechanism and operate counterclockwise to separate the locking/grounding of the lower door; ③. Insert the handle into the isolation operation hole of the G mechanism and operate counterclockwise to close the isolation switch; ④. Insert the handle into the energy storage operation hole of the V mechanism and operate clockwise to store energy in the circuit breaker; ⑤. Press the green button on the V mechanism to close the circuit breaker switch.
Power outage operation:
①. Press the red button on the V mechanism to open the circuit breaker switch; ②. Insert the handle into the isolation operation hole of the G mechanism and operate clockwise to open the isolation switch; ③. Insert the handle into the grounding operation hole of the G mechanism and operate clockwise to close the grounding switch; ④. Insert the handle into the energy storage operation hole of the V mechanism and operate clockwise to store energy in the circuit breaker; ⑤. Press the green button on the V mechanism to close the circuit breaker switch, and only then can the lower door be opened.
