Product descriptions from the supplier
The NHK-J12 environmental protection cabinet PT isolation operating mechanism is suitable for the 5.2 series environmental protection cabinet PT isolation unit. The mechanism adopts the principle of compression spring releasing energy through the middle. The isolation operating shaft is located on the right side of the mechanism, and the grounding operating shaft is located on the left side of the mechanism. It adopts a single rod mechanical interlocking structure, and the overall structure of the mechanism is compact and easy to install. The mechanism interlocking meets the five prevention requirements. The operating mechanism complies with the 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; 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).
