Closed discharge gap dynamic seal distance adjusting structure for neutral point protection device

Abstract

The application discloses a closed discharge gap dynamic sealing distance adjusting structure for a neutral point protection device, which comprises a sealing shell, a gap grounding electrode and an adjusting rod. A cover plate is fixedly arranged on the port of the sealing shell, a through hole is arranged in the middle of the cover plate, and a grounding shield is penetrated into the through hole. An insulating plate is fixedly arranged between the grounding shield and the cover plate, a channel capable of penetrating into the gap grounding electrode is arranged in the middle of the grounding shield, and a grounding row is arranged on the end of the grounding shield outside the cover plate. One end of the gap grounding electrode penetrates into the sealing shell through the grounding shield, and the other end is provided with a connecting block. The adjusting rod is inserted into the channel and fixed with the connecting block, and the adjusting rod is threadedly connected with the grounding shield. The application aims to provide a distance adjusting structure with good sealing performance and capable of adjusting the distance of the discharge gap according to requirements.
