When the switch of the high-voltage switchgear is not stored, it cannot be closed by either the electric button or the mechanical forcing button. The main reason is that the spring operating mechanism is in a released state and there is no energy to drive the switch contacts. The switch of the spring operating mechanism stores energy through the energy storage motor before the normal closing. If the energy storage circuit fails, it can also be stored manually by using a rocker. Each time the energy storage is available for the switch to complete one closing and one opening.
Solution:
First confirm where the fault occurred in the organization. Remove the front panel of the switchgear and use the tool to press the closing half shaft under the closing coil to see if the switchgear can be closed.
If the switch cannot be closed, it is from the main shaft of the switchgear cabinet to the closing half shaft. It may be that the drive rod is deformed.
If it can be closed, it may be that there is a dry button at the closing half of the closing button, so that the closing is not triggered in place, and the closing button cannot be ejected because of the dryness.
