A high-voltage transmission line enters the electric field equipotential live working method

Abstract

The invention relates to an equipotential live working method for entering electric field of a high-voltage transmission line. An equal potential electrician takes an electric field entering-and-outing vehicle for entering the electric field along tension insulator strings. The electric field entering-and-outing vehicle can advance or retreat on two tension insulator strings. According to the method, the equal potential electrician enters the electric field in a sitting gesture, thereby reducing physical power consumption of operation personnel. Compared with an electric field entering method in which the left foot and the right foot are respectively placed on a first insulator and a third insulator and the left hand and the right hand are placed on two insulators on the other insulator string, the method of the invention has an advantage of making the operator more comfortable and more convenient, so that the operator has enough physical power for finishing the subsequent live operation. The electric field entering-and-outing vehicle of the invention has advantages of simple integral structure, small material weight, low studying cost of the operator, and easy operation. Furthermore high operation efficiency and high operation safety can be ensured.

Description

Technical field [0001] The invention belongs to the field of ultra-high voltage power transmission and transformation, and in particular relates to a method for high-voltage power transmission lines entering an electric field into an equipotential electrification operation. Background technique [0002] When an ultra-high voltage transmission line fails, due to the large transmission power of the line, it is often necessary to adopt a live line elimination method. Using the "span two short three" method to enter the electric field freely along the insulator string is a relatively traditional way to enter the electric field. However, this method has the following disadvantages: [0003] 1) The distance between the tension insulator strings of the high-voltage transmission line is relatively long. When the equipotential electrician enters the electric field process, the hands must always be kept straight. The operator cannot maintain a half-squatting state and it is difficult to mov...

AI Technical Summary

Problems solved by technology

[0003] 1) The distance between the tension insulator strings of high-voltage transmission lines is relatively long. When an equipotential electrician enters the electric field, his hands must be kept straight all the time. The operator cannot maintain a half-squat state and has difficulty moving;

[0004] 2) The number of insulators in the tension insulator series of high-voltage transmission lines is large, the labor intensity of the operators is relatively high, and the physical exertion is serious, which affects the follow-up live work and even fails to complete the work
