Technical Field

[0001] The utility model relates to the technical field of electric power engineering, in particular to an electric power engineering grounding device. Background Art

[0002] During the use and maintenance of the existing power system and back-end electrical equipment, it is often necessary to add a grounding device to achieve system grounding connection and equipment grounding electrical connection. For the corresponding grounding device, in the prior art, a temporary grounding anchor may be pre-buried near the grounding point. For this occasion, an electrical connection line is used to connect the grounding anchor and the corresponding cable or equipment. However, in most cases, especially for the grounding of power conductors, there is generally no pre-buried grounding anchor on site. In this case, a temporary ground anchor rod is generally anchored into the earth, and the electrical conduction between the corresponding repaired line and the earth is completed through the lead wire connection. This grounding method has safety hazards and needs to be improved.

[0003] After searching, the China Patent Network has disclosed a grounding device for electric power engineering, and its authorization announcement number is CN220291092U.
