Mechanism NHK-J12 na isolation PT a cikin kofin haɗin kasa yana da muhimmanci don unit PT isolation na series 5.2. Mechanism ya yi amfani da siffar tushen spring mafi girma a tsakiyar mechanism. Shaft na isolation operation yana cikin gabashin zuwa daga kan hagu, kuma shaft na grounding operation yana cikin gabashin zuwa daga baya. Ya yi amfani da structure na mechanical interlocking mai zane, kuma structure na overall ta mechanism yana da muhimmanci da shi da yake da yake. Interlocking na mechanism yana tabbatar da requirements na five prevention. Mechanism yana da shiga da standards kamar 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; Power transmission completed.
Power outage operation:
①. Insert the handle into the isolation operation hole of the G mechanism and operate clockwise to open the isolation switch; ②. Insert the handle into the grounding operation hole of the G mechanism, operate clockwise to close the grounding switch, power off and complete the grounding operation (at this time, the lower door can be opened).
