Special-purpose tool for ground potential resetting of suspension insulator wire-side socket clevis W-type pin

Abstract

A special-purpose tool for ground potential resetting of a suspension insulator wire-side socket clevis W-type pin is provided. The special-purpose tool comprises a shell; the shell is a rectangular shell with one opening formed at one side; a push block is arranged inside the shell; the push block slides along the shell; a through hole is formed in a surface of the shell which is opposite to the opening; a push rod passes through the interior of the through hole; one end of the push rod is connected with the push block; the other end of the push rod is connected with an upright rod; the push rod is composed of two transverse rods and one vertical rod; the upper end of the vertical rod is connected with the rear end of one of the transverse rods; the lower end of the vertical rod is connected with the front end of the other transverse rod; and the transverse rod connected with the upper end of the vertical rod is wound with a first spring. With the special-purpose tool used in ground potential electrical engineering provided by the invention adopted, the suspension insulator wire-side socket clevis W-type pin can be reset; outage maintenance can be avoided; the frequency of temporary shut-down of equipment can be lowered, and therefore, the availability factor of the equipment can be increased; electrified operation working time can be shortened; work efficiency can be improved; and the safety of electrified operation and the reliability of power supply can be improved.

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 heads on the side of the suspension insulator wires often come out. 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 si...

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 suspension insulator, and there are often deviations in the reset, and the working time with the point 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
