High-voltage ground line device

Abstract

The present invention discloses a high-voltage ground line device. The high-voltage ground line device comprises a dual-ring ground terminal and an insulating rod. A lantern ring 11 is arranged at one side of the dual-ring ground terminal; and the insulating rod comprises a pickup ground line special plug which is provided with two connecting plugs, and the length of one connecting plug located at the top is longer than the length of the connecting plug located at the bottom. The insulating rod dual-plug connecting plug can control the angle of the ground line connecting plug and the line when the ground line is hooked and dismounted, workers can control the lines to be located at the lower portion of a spring clamp, the dual-ring structure can ensure that the ground line connecting plug cannot rotate, and the ground line connecting plug can be easily hanged on the lines when the insulating rod is pulled down. The structure is simple and reasonable so as to greatly satisfy the requirement of the electric power system work.

Description

technical field [0001] The invention relates to a high-voltage grounding wire device, in particular to a mountable grounding wire for voltage levels of 66kV and 220kV, and belongs to the field of electric system safety tools. Background technique [0002] In the power system, the grounding wire is used to prevent the staff from getting an electric shock when there is an accidental voltage on the equipment and lines that have been powered off. Connecting and removing the grounding wire is one of the necessary steps in the power transmission operation, which is crucial to production safety. Important, whether the ground wire can be connected well becomes a necessary condition to ensure safe production. However, the existing high-voltage grounding wires and insulating rods such as figure 1 and figure 2 As shown, it includes 1 ring on the side of 4 ground wire connector, 2 ground wire connection sleeve connecting 3 ground wire and 4 ground wire connector, 5 spring clip inside...

AI Technical Summary

Problems solved by technology

[0003] When hooking the ground wire, the purpose is to clip the high-level wire into the 5 spring clips. Since there is only one 1 ring on the side of the 4 ground wire connector, when the 4 ground wire connector is connected to the wire, the 8 ground wires on the insulating rod The special plug for the ground wire is worn inside the 1 ring, and the ground wire head is lifted up and hung on the wire, but the special plug for the 8 pick ground wire will rotate in the 1 ring during the process, so that the 5 spring clips on the 4 ground wire connector cannot be fixed. Align the wires vertically downwards. When the staff pulls down the insulating rod, the 4 grounding wire connectors cannot easily clamp the wires in the 5 spring clips, and the 4 grounding wire connectors can easily be removed from the 8 spring clips during repeated attempts. The special plug for picking the ground wire slips, which poses a threat to the safety of equipment and staff below the height. The problem is the same when the ground wire is removed.
