Grounding method for high and low-voltage line maintenance operation and special grounding wire grounding body

Abstract

The invention relates to a grounding method for high and low-voltage line maintenance operation and a special grounding wire grounding body, which belong to the technical field of electric power maintenance. According to the technical scheme, the special grounding wire grounding body comprises a grounding rod (1), a strike crossbar (2) and a wiring board (3), wherein the lower end of the grounding rod has a conical structure (4); the strike crossbar is arranged on the grounding rod, and is vertical to the grounding rod; a closed ring (5) serving as the lowest entry mark is arranged on the grounding rod away from the peak of the lower conical structure by 61cm; the wiring board is arranged on the grounding rod above the closed ring; a signboard (7) is also arranged on the wiring board, and corresponds to the closed ring on the grounding rod. The special grounding wire grounding body provided by the invention is convenient to carry, install and uninstall, can be used repeatedly, has short maintenance time, and is particularly suitable for grounding for high and low-voltage line maintenance operation to ensure safe grounding and firm and reliable grounding and eliminate potential risks, thereby completely meeting the related safety requirement of China, and improving the safety and reliability.

Description

technical field [0001] The invention relates to a grounding method for high and low voltage line maintenance work and a special grounding wire grounding body, belonging to the technical field of electric power maintenance. Background technique [0002] At present, in the maintenance of high and low voltage lines, the grounding body is generally used for the high and low voltage grounding wires. Article 4.4.7 of the "Safety Regulations" stipulates that the depth of the grounding body should not be less than 0.6 meters under the ground. During work, the grounding body used in the background technology is connected to the grounding wire with a single hole, the bolts are easy to loosen, and the staff cannot accurately grasp the depth of the grounding body into the ground. There are problems such as damage to the location of the ground and time hole, and some staff do not understand the regulations of the "Safety Regulations", thinking that only grounding is enough, ignoring the ...
