Description

Wire tensioner for indirect live wire {INDIRECT LIVE WIRE TENSIONER}

The present invention relates to a wire tensioner for indirect live wire work, and more particularly, enables wire tension work with a small force and separates cut wires to improve safety and facilitate indirect live wire work at the same time. It relates to a wire tensioner for indirect live wires.

In general, live wire work refers to line work performed while continuing to transmit power to a distribution line. Because the risk of safety accidents is very high, live wire work is performed in cases where it is difficult to cut off power, such as in transmission and distribution facilities, and workers working on live wires must use insulation protection or protective equipment.

Live wire work of distribution lines can be divided into direct live wire work and indirect live wire work. Direct live wire work is a method in which the worker wears insulated gloves in an insulated bucket and then works in a live wire state. On the other hand, indirect live wire work is a method of working using an insulated tool such as a hotster. Therefore, indirect live wire work takes a lot of time, but it can greatly reduce the risk of safety accidents.

The live wire work includes inspection, repair, replacement, and cleaning of wire line components such as support insulators, and a direct live wire work method or an indirect live wire work method may be appropriately used depending on the type of work.

In recent years, in carrying out new and maintenance work for distribution lines, the proportion of live wire or uninterruptible work that does not interrupt the supply of electricity is increasing. In the past, there were many direct live-line work in which workers directly contact high-voltage power lines, but now, for safety reasons, the work method is in the process of being converted to indirect live-line work.

When working with indirect live wires, it is necessary to perform various operations such as gripping, fixing, removing, cutting and spreading wires or equipment in the live wire state to be installed or removed from utility poles. Therefore, inevitably, the auxiliary worker wears insulation equipment, takes the risk of direct contact with the line, and stably holds and fixes the wire or equipment.

However, conventional indirect live wire devices that rely only on manpower, such as hot sticks, have insufficient gripping power and are unable to perform various high-level tasks, and the labor intensity of the work is so high that safety accidents due to worker's mistakes or limitations in physical strength frequently occur during continuous work. There is a problem with
