Problems solved by technology

[0005] 1. It cannot effectively solve the contradiction between tree-line and line-line, which increases line faults;
[0006] 2. While frequent maintenance and replacement increase the cost, it also increases the labor intensity of line operators and reduces the reliability of power supply;
[0007] 3. The local wear resistance of the tree-line contradiction is not high;
[0008] 4. After the outer insulation of the wire is stripped during construction, the means of restoring the insulation is single

Embodiment Construction

[0040] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0041] Embodiment 1 of the present invention, such as figure 2 As shown, a repair tube for overhead wire is wrapped on the outside of overhead wire 1, wherein the repair tube includes an insulating protective tube 2 and a composite protective layer 3, and the insulating protective tube 2 is wound or wrapped around the overhead wire 1 The outer side of the insulating protective tube 2 and the overhead conductor 1 are provided with an adhesive 5; the composite protective layer 3 is wrapped on the outer side of the insulating protective tube 2.

[0042] Further, in order to increase the adsorption force of the insulating protection tube 2 and the overhead wire 1, the second embodiment of the present invention, such as image 3 As shown, the difference from Embodiment 1 is that: the insulating protective tube 2 is provided with movable openings a...

Abstract

The invention relates to a maintenance pipe for an overhead wire. The maintenance pipe for the overhead wire covers the outer side of the overhead wire. The maintenance pipe is characterized by comprising an insulated protective pipe body and a composite protective layer, wherein the insulated protective pipe body is wound around the outer side of the overhead wire, and adhesive is arranged between the insulated protective pipe body and the overhead wire; the composite protective layer covers the outer side of the insulated protective pipe body. The maintenance pipe for the overhead wire can effectively avoid the conflict between a tree and the wire and between the wire and a road, prevent or reduce faults, reduce the production cost for a power supply department, relieve the labor intensity of circuit operation personnel and improve power supply reliability. The wear resistance of the overhead wire can be improved, and the overhead wire has good anti-aging performance; the maintenance pipe is small in unit weight and small in section and has little influence on the sag of the wire; during wire operation, the maintenance pipe can be installed in a electrified mode; and the safety coefficient is increased by the adoption of the maintenance pipe.

Description

technical field [0001] The invention relates to a wire protection and maintenance device, in particular to a maintenance pipe for overhead wires. Background technique [0002] With the rapid development of the distribution network, the power supply channel is covered by trees, severe corrosion, external force damage and many other factors. In order to solve this problem, overhead insulated wires are used for power transmission. Some of the problems encountered, the price is much cheaper than cable transmission, so it is widely used in the distribution network. [0003] However, due to the complex geographical environment of power distribution in urban areas, short-circuit grounding and accidental tripping often occur, resulting in reduced reliability of power supply; Vulnerable to external damage; 3. After use, due to long-term exposure to sunlight, rain, and lightning, cracks or peeling may occur, affecting its mechanical and insulating properties. Therefore, improvements...
