Grounding wire of overhead power transmission line

Abstract

The invention relates to a grounding wire of an overhead power transmission line, which comprises a grounding chuck (6), insulating ropes (4), a soft copper wire (5) and a spring hook head (1), wherein one end of the soft copper wire (5) is connected onto the spring hook head (1), and the other end of the soft copper wire (5) is connected onto the grounding chuck (6); the grounding chuck (6) is fixed on a tower or a grounding pole embedded into ground; the spring hook head (1) is chucked and held on a guide line; a hook head turnover mechanism (3) is arranged below the spring hook head (1); and the two insulating ropes (4) are respectively connected onto a handle part at the upper part of the spring hook head (1) and the hook head turnover mechanism (3). The grounding wire of the overhead power transmission line, provided by the invention, effectively solves the problem of difficulty in hooking the grounding wire of the overhead power transmission line with 220 to 500kV, and existing three degrees of freedom of a guide line terminal controlled by an operator is improved to be more than five degree of freedoms.

Description

technical field [0001] The invention relates to a grounding wire of an overhead transmission line, in particular to a grounding wire of a high-voltage overhead transmission line. Background technique [0002] When the high-voltage overhead transmission line is powered off for maintenance, the maintenance party must hang ground wires at both ends of the maintenance area to protect the maintenance area from the danger of sudden calls. Composed of copper wire and wire clip, the wire clip includes a spring clip and a clip tongue. When using it, ground the grounding clip first, then use the clip tongue to spread the spring clip, and finally put down the wire clip with an insulating rope, and try to make the clip tongue touch The wire falls off, clamp the wire, and complete the steps of installing the ground wire. When removing it, pull up the insulating rope firmly to separate the spring clip from the wire. [0003] However, the wire clips used to connect the grounding wires to ...

Problems solved by technology

[0003] However, the wire clips used to connect the grounding wires to the wires are laborious to install and disassemble, and because they can only control the three degrees of freedom of moving in the vertical direction and rotating in the direction of the line and the horizontal line during installation, when installing the grounding wire Since the degree of freedom of rotation in the vertical direction cannot be controlled, it is difficult for the wire clamp to clamp the wire, so you can only try to touch the wire, such as installing the ground wire when there is wind, and the freedom of movement along the direction of the line, the direction of the horizontal line, and the direction vertical to the ground The three degrees of freedom of the rotation degree of freedom cannot be controlled, which is time-consuming and labor-intensive, which makes it very difficult to install the grounding wire
