Embodiment 1

[0019] Embodiment 1: In this wire support tool for live pole operation, one end of the insulating rod 1 is equipped with a fixed strut head 2, and the other end is equipped with a movable strut head 3 that can be movably matched with the insulating rod 1. Meet 35mm at the same time 2 -240mm 2 For the needs of overhead lines, according to the regulations for the operation of live poles, a safe distance of more than 2.5m should be maintained between the conductors on both sides of the pole, but the farther away from the opening point, the smaller the distance between the conductors on both sides, and a section of conductors should be kept The spacing between the wires must reach the safe distance, and the width of the wires must be greater than 2.5m. According to the sampling test, when the wires are stretched to 2.8m, the distance between the wires within the range of 10.9m on both sides of the opening point can reach 2.5m. above security requirements. Because movable strut h...

Embodiment 2

[0023] Embodiment 2: Both the insulating rod 1 and the movable strut head 3 are the same as those described in Embodiment 1, and the fixed strut head 2 is embedded in the end of the insulating rod 1 and fixed by screws 5 in the radial direction.

Abstract

This invention relates a conducting wire supporter for electrified pole operation, wherein one end of an insulating bar is set with a fixed supporter head, and the other end of the same is set with a movable supporter head movably matched with the insulating bar; the movable supporter head is connected with a clamp ring in up and down manner via a conducting wire clamp slot; one end of the insulating bar is set with plural through holes; the movable supporter head is fastened to the insulating bar via the clamp ring; two tail ends of the clamp ring are fixed via fixing bolt; further, the clampring is fixed to the through hole via movable bolts in radial manner. This invention achieves beneficial effects as follows: firstly, it is small in dimension, ingenuous in utilization, convenient for operation, and short in assembling / disassembling time; secondly, it is excellent in insulating degree, safe and reliable, and is able to achieve mechanical strength meeting standard; thirdly, it controls cost, effectively enhances reliability of power supply; fourthly, it promotes maintenance of regional electric network, and ensures safe and stable operation of electric network.

Description

technical field [0001] The invention relates to a tool used in live pole operation, in particular to a wire support tool used in live pole operation. Background technique [0002] Live pole operation is the work of pulling out, moving or replacing poles without power failure. In order to ensure a sufficient safe distance between the pole and the wires on both sides, it is necessary to use insulating tools to spread the wires on both sides outward for a certain distance. Therefore, the insulating tool that stretches the wire is an important tool to ensure the safety and smooth completion of the live pole work. So far, there is no tool that is really suitable for supporting wires for 10kV live pole work. Contents of the invention [0003] The invention provides a wire support tool for live pole operation, which ensures that the 10kV live pole operation can be carried out safely and smoothly. [0004] The technical solution adopted by the present invention to solve the tec...
