The use steps of metal enclosed switchgear are very rigorous. Now Zhengguang electric appliance will explain it to you: I hope it can help you when you encounter problems.

Here, I'd like to introduce the use sequence of the load switch. As for closing, when the load switch is in the opening state, insert the operating handle into the operating hole of the load switch and turn it clockwise (about 180 degrees) to close it. As for breaking, when the load switch is in the closing state, the load switch can be opened by manual tripping button or tripping electromagnet. For the load switch equipped with fuse with impactor, the impactor can also open the load switch after the fuse is blown.

Secondly, how to operate in case of power failure? First open its load switch to release the interlock between it and the isolation and grounding switch, insert the operating handle into the operating hole of the isolation and grounding switch, rotate clockwise (about 90 degrees), and the isolation knife will be opened. Then rotate clockwise (about 90 degrees), the grounding switch closes quickly, and then insert the edge diaphragm to release the door interlock, and then open the door for maintenance.

Then I'll talk about what's important about power transmission. First close the cabinet door, pull out the edge partition, lock the cabinet door, insert the operating handle into the operating hole of the isolation and grounding switch, turn it counterclockwise (about 90 degrees) to disconnect the grounding switch, and then turn the operating handle counterclockwise (about 90 degrees) to disconnect the grounding switch, operate the load switch and close the power transmission.
