Abstract
The utility model discloses a guide rail type grounding device for a high-tension switch cabinet. The grounding device comprises a cabinet body and a drawer arranged in the cabinet body. Guide rails are arranged on two sides at the bottom in the cabinet body, and guide wheels are arranged on two sides of a push-in end of the drawer to be matched with the guide rails. Copper bars are fixed above the guide rails in the cabinet body and electrically connected with a grounding bus of the high-tension switch cabinet through wires. Grounding clamps are fixed on two sides of the push-in end of the drawer and electrically connected with a breaker of the high-tension switch cabinet. According to the guide rail type grounding device for the high-tension switch cabinet, when the drawer is pushed in the cabinet body, the copper bars are inserted into the grounding clamps to form a grounding circuit, so that not only the installation and the maintenance are convenient, but also the safety and the reliability are high.
