Abstract

The invention relates to an outdoor high-voltage cable head grounding structure and method, and belongs to the technical field of safety protection during power cable maintenance. According to the technical scheme, a merger clamp base (12) is fixedly connected with a grounding ring (2), an arc-shaped clamping groove I (13) is formed in the merger clamp base (12), an arc-shaped clamping groove II (17) is formed in one side of a merger clamp pressing plate (16), a clamping table is arranged on the other side of the merger clamp pressing plate (16), the merger clamp pressing plate is arranged on the merger clamp base in a pressing mode through a fixing bolt (11), the clamping groove I and the clamping groove II are communicated with each other to form a clamping groove, the clamping groove I and the clamping groove II communicate with one another to form a clamping groove, and the wire core is clamped in the clamping groove; and the other side, away from the merger clamp base, of a grounding ring is not coated with an insulating layer, the exposed part is a grounding part, one end of the grounding wire is connected with the grounding part, and the other end of the grounding wire is connected with a grounding drill rod arranged on the ground. According to the invention, the grounding problem of the outdoor high-voltage cable head can be effectively solved, an operator can obtain grounding protection when disconnecting the cable head, and the working safety performance is ensured.

Description

technical field [0001] The invention relates to an outdoor high-voltage cable head grounding structure and method, and belongs to the technical field of safety protection during power cable maintenance. Background technique [0002] In recent years, with the development of science and technology, the laying of power cables has become more and more extensive, and its market share has continued to increase. However, with the popularization of cables, their existing problems have gradually become prominent. Through investigation, it has been found that some cables often have the problem of not having a suitable ground wire position during use, which poses a great safety hazard to daily maintenance personnel and also poses a threat to the safety of The operation and maintenance work has caused a lot of trouble. Contents of the invention [0003] The purpose of the present invention is to provide an outdoor high-voltage cable head grounding structure and method. The three phas...
