Method capable of entering multi-loop vertically-arranged wire equipotential operation

Abstract

The invention discloses a method capable of entering multi-loop vertically-arranged wire equipotential operation, and aims to provide an equipotential operation method with high operation efficiency.The method comprises the following steps: (1) an unmanned aerial vehicle hangs the tipping bucket tackle on an overhead ground wire by using an insulating pull plate connected with a hook; (2) a hanging bracket is hung on a wire through an insulating rope on the tipping bucket tackle; (3) one end of the insulating rope is fixedly tied to one pulley at the bottom of the hanging bracket through thehanging bracket, and the middle of the insulating rope penetrates through the hanging bracket and the hanging basket and then penetrates through the other pulley at the bottom of the hanging bracket to form a pulley combination; a ground electrician uses an electric winching machine to pull an insulating rope, the hanging bracket and the hanging basket are hung to a working phase, an equipotentialoperator sits in the hanging basket, and when the equipotential operator gets close to the working phase, a potential transfer rod is used for transferring the potential; and (4) after the operationis finished, the hanging bracket and the hanging basket are firstly placed on the ground, then the hanging frame is put down, and finally the tipping bucket tackle falls off from the overhead ground wire.

Description

technical field [0001] The invention relates to the technical field of power grid maintenance, in particular to a method for equipotential operation capable of entering multi-loop vertically arranged conductors. Background technique [0002] In the live overhaul process of transmission lines, using the ladder method to enter the strong electric field for equipotential work is the most commonly used method in China at present. Using this method to work has the following problems: [0003] (1) The physical energy consumption of the operators is high, and the requirements for the physical fitness of the operators are extremely high; [0004] (2) There are limitations in the scope of work, and it is not possible to enter the electric field through the ladder method on vertically arranged and multi-circuit lines; [0005] (3) The operation method is cumbersome, and it is difficult to throw the rope when hanging the ladder; [0006] (4) The operation risk is high. [0007] In o...

Problems solved by technology

[0003] (1) The physical energy consumption of the operators is high, and the requirements for the physical fitness of the operators are extremely high;

[0004] (2) There are limitations in the scope of work, and it is not possible to enter the electric field through the ladder method on vertically arranged and multi-circuit lines;

[0005] (3) The operation method is cumbersome, and it is difficult to throw the rope when hanging the ladder;

[0006] (4) High operational risk

[0007] In order to solve these problems and meet the requirements of multi-circuit and vertically arranged wire equipotential operation, and overcome the difficulties that the equipotential operators consume too much energy when climbing the ladder and the ladder method cannot meet the inter-phase combination gap, there is an urgent need for a multi-circuit vertical arrangement. The method of wire equipotential operation to meet the development needs of live work, reduce operation risk and improve work efficiency
