Embodiment Construction

[0032] The present invention will be further described below in conjunction with drawings and embodiments.

[0033] refer to figure 1 , the transmission line maintenance grounding wire of the present invention includes a wire end clip 6 that can be connected to and removed from a power transmission line, a grounding terminal fixing clip 2 that can be firmly connected to the grounding terminal, and a grounding short-circuit wire 3 that connects the two. The wire end clamp 6 is also connected with a high-strength insulating rope 4 for hooking and removing the wire end clamp. Wherein, a GPS information transceiver 1 is also installed on the ground terminal clamp 2 .

[0034] The wire terminal clamp 6 can adopt the grounding clamp structure of the prior art. Two symmetrically arranged clamping blocks are H-shaped butt joint, and a connecting hole is symmetrically arranged on the two clamping blocks respectively, and bolts are used to pass through the connecting holes at the inters...

Abstract

The invention provides earthing lines of power transmission lines overhauling and a hooking method thereof, and the earthing line comprises a wire end clip capable of hooking and dismantling with a power transmission line, an earth terminal fixed clamp capable of being fixedly connected with an earth terminal and an earth short-circuit line for connecting the wire end clip and the earth terminal fixed clamp. The wire end clip is also connected with an insulating rope for performing the operation of hooking and dismantling the wire end clip, a GPS information transceiver is arranged on the earth terminal fixed clamp, and the wire end clip is also provided with a reversed hook and a magnet sheet. The invention can realize GPS precise location for power transmission line overhauling positions, avoid easily-generated risks of malposition caused by false hooking and dismantling and the process of hanging earthing lines by maintenance personnel, lower work difficulty and be widely used in overhauling earthing protection of high-voltage power transmission line.

Description

technical field [0001] The invention relates to the field of grounding protection tools during maintenance of power transmission lines, in particular to a grounding wire for maintenance of power transmission lines and a mounting method thereof. Background technique [0002] The grounding wire is a safety tool often used in electric power safety production. Power outage, power inspection, and grounding wire are important technical measures to ensure the safety of transmission line power outage maintenance. An important guarantee for safety and equipment safety. Since the grounding wire is installed to protect the safety of the electrical maintenance personnel during operation, if the grounding wire is installed in the wrong position, it will not be able to protect the personnel; at the same time, if the grounding wire is not removed in time after the transmission line maintenance is completed, it will Causing vicious accidents of power transmission with ground wires, so prev...
