Description

Technical Field

[0001] The utility model belongs to the technical field of grounding equipment, in particular to a flexible graphite grounding electrode resistance reduction device which is easy to connect. Background Art

[0002] Grounding devices are used to protect electrical equipment and personnel. By establishing a good electrical connection between the metal parts of the equipment and the ground, current is safely directed to the ground, preventing electric shock or fire. Existing graphene grounding electrodes have a smooth, pointed end for insertion into the ground, which can easily detach and lack stability.

[0003] A search revealed a Chinese patent document (authorization publication number CN221687785U) describing a graphene grounding electrode structure, which relates to the field of grounding mechanism technology. The structure comprises a main body, a graphene grounding wire plugged into the top of the main body, a fixing mechanism fixedly mounted on the top of the main body, a maintenance mechanism clamped to the top of the main body, and a grounding mechanism fixedly mounted on the bottom of the main body. The fixing mechanism comprises a base, a sealing cover, and a plug rod. The utility model secures the graphene grounding wire to the main body via the fixing mechanism, preventing it from loosening between the graphene grounding wire and the main body, providing a more secure connection. The maintenance mechanism allows the top of the graphene grounding electrode structure to be opened for easy maintenance of the internal graphene grounding wire. The grounding mechanism allows barbs mounted on a movable limiting slide bar to penetrate the inner wall of the plug rod and then penetrate into the soil on both sides, thereby preventing the grounding mechanism from being removed and maintaining a stable connection to the ground. Although the barbs are present, they are not only few in number but also easily interfere with the grounding electrode and easily become detached from the ground, resulting in a lack of security.
