An isolated grounding switch for 220kV combined electrical apparatus
By installing a placement box and a silica gel desiccant pack inside the mechanism box of the isolating grounding switch, the problem of moisture absorption by traditional isolating grounding switches in high humidity environments is solved, thus achieving stable operation of electrical components and extending their service life.

AI Technical Summary
Traditional isolating grounding switches are prone to moisture in high humidity environments, which can lead to a decrease in the insulation performance of electrical components and potential short-circuit faults, thus shortening their service life.
A box is installed inside the mechanism box of the isolating grounding switch to hold a silica gel desiccant pack. The design of the fixed frame, fixed cover and elastic plate facilitates the replacement and changing of the silica gel desiccant pack and facilitates regular maintenance.
This improved the dryness inside the mechanism housing, ensuring the stable operation of the electrical components in the motor mechanism housing, preventing the motor from getting damp, and extending the service life of the motor and other control components.
