Description

Technical Field

[0001] The utility model relates to the field of protection devices, in particular to a grounding protection device for electric power construction with good reliability. Background Art

[0002] Grounding for power construction is a very important safety measure designed to protect personnel and equipment in the workplace from electric shock hazards. The grounding system disperses and eliminates the current by directing it into underground conductors, thereby protecting personnel and equipment.

[0003] When connecting the grounding wire, a conductive rod is usually directly embedded in the ground, and a connecting pole ear is connected to the outside of the conductive rod, so that the grounding wire can be installed on the connecting pole ear with a bolt. When connecting the temporary grounding wire, a conductive clamp is usually used to clamp it directly on the outside of the conductive rod, and the conductive rod is usually exposed to the outside. Therefore, if a worker walks near the conductive rod and accidentally touches the grounding wire, the connection between the grounding wire and the conductive rod will become loose or even detached, which makes it inconvenient to shield and protect the conductive rod where the grounding wire is installed.
