Ground potential reset suspension insulator wire side bowl head w pin special tools

Abstract

Ground potential reset suspension insulator wire side bowl head W pin special tool, including a shell, the shell is a rectangular parallelepiped shell with one side open, a push block is set inside the shell, the push block slides along the shell, and the opening on the opposite side of the shell A through hole is set on the surface, and the push rod passes through the through hole. One end of the push rod is connected to the push block, and the other end of the push rod is connected to the vertical rod. The push rod is composed of two horizontal rods and a vertical rod. The upper end of the horizontal rod is connected to the rear end of one of the horizontal rods, the lower end of the vertical rod is connected to the front end of the other horizontal rod, and the first spring is wound on the upper horizontal rod. The ground potential electrician provided by the invention operates with a special tool to reset the W pin on the side bowl head of the suspension insulator wire. The invention can meet the needs of this work, avoid power outage maintenance, reduce the number of temporary stoppages of equipment, increase the availability factor of equipment, shorten the working time of live work, improve work efficiency, and improve the safety and power supply reliability of live work.

Description

technical field [0001] The invention relates to an electric power tool, in particular to a special tool for the ground potential reset suspension insulator wire side bowl head W pin. Background technique [0002] In ultra-high-voltage transmission lines, especially in 500 kV lines, inspectors found that the W pins in the bowl head on the side of the suspension insulator lead protrude frequently. This defect seriously threatens the safe and stable operation of the line and needs to be resolved in time. At present, the W pin on the side of the bowl head of the suspension insulator wire is generally reset manually during the power outage maintenance process. This method must wait for the power outage maintenance. During the waiting process, accidents are likely to occur, and the safety hazard is relatively large. Or live work is performed to reset the W pin on the side of the hanging insulator wire. After live work, the equipotential electrician directly pushes the W pin on the...

AI Technical Summary

Problems solved by technology

At present, the W pin on the side of the bowl head of the suspension insulator wire is generally reset manually during the power outage maintenance process. This method must wait for power outage maintenance, and accidents are likely to occur during the waiting process, which poses a great safety hazard.

Or live work is performed to reset the W pin on the side of the hanging insulator wire. After live work, the equipotential electrician directly pushes the W pin on the side of the hanging insulator wire into the bowl hanging plate after entering the electric field, and uses tools such as insulation boards to reset. There is no special tool for the side bowl head W pin of the wire side of the hanging insulator, and the reset often deviates, the live working time is longer, the work efficiency is low, and the safety is low

Equipotential live work has higher requirements on personnel, tools, environmental humidity, and safety distance, and equipotential live work is more complicated than ground potential live work
