Ground potential rod cutter exchanging device

Abstract

The invention relates to a ground potential rod cutter exchanging device which is arranged on a high-voltage wire tower or an electric pole. The device comprises a rotary support, a hanging arm, a first fixed pulley, a handing hook, a rope, a second fixed pulley and a moving pulley; the rotary support is connected with the high-voltage wire tower or the electric pole; the hanging arm comprises a free end and a fixed end; the fixed end of the hanging arm is connected with the support; the fixed end of the hanging arm is provided with the first fixed pulley; the fixed end of the handing arm is provided with the second fixed pulley; the rope is sequentially sleeved on the first fixed pulley, the second fixed pulley and the moving pulley, and is fixed at the part of the second fixed pulley; and the hanging hook is arranged on the moving pulley. Compared with the prior art, the device provided by the invention has the advantages that the power failure time can be reduced, the efficiency of overhauling operation is improved effectively, the working amount of the operation is reduced greatly, and the like.

Description

technical field [0001] The invention relates to a rod-knife replacement device, in particular to a ground potential rod-knife replacement device. Background technique [0002] On the distribution line, the pole cutter is an electrical device that changes the operation mode of the power grid and controls the power flow of the system. After the rod knife has been used for a certain number of years, it needs to be replaced to ensure the stable and reliable operation of the line. In order to avoid power outages on the line, usually the power supply company uses live work as much as possible to replace the pole cutter. [0003] At present, the operation method of exchanging the rod knife with electricity must rely on the insulated arm truck and use the intermediate potential operation method. However, when the construction site for exchanging pole knives is located beside rivers and lakes, beside high-speed railways, next to elevated rail transit, near farmland and farms, and o...

AI Technical Summary

Problems solved by technology

However, when the construction site for exchanging pole knives is located beside rivers and lakes, beside high-speed railways, next to elevated rail transit, near farmland and farms, and on the side of crowded and narrow roads, the insulated arm truck cannot stop, that is, the existing live working method cannot be used Carrying out work, exchanging the rod knife will have to power off the line

Assuming power outage replacement, at least two lines must be out of service each time, and the average outage time for power outage replacement rods and knives is at least 4 hours, which seriously affects the normal power consumption of power users and causes economic losses for both users and power companies
