Electrified repairing method for 10kV line aerial conductors and insulating wire lifter

Abstract

The invention relates to the field of electrified repairing of electric line aerial conductors and especially relates to an electrified repairing method for 10kV line aerial conductors and an insulating wire lifter. The electrified repairing method is characterized by comprising the following steps: separating aerial conductors from a cross arm by virtue of a crane and the insulating wire lifter; firstly, lifting the insulating wire lifter to a position vertically above the cross arm by the crane; insulating and covering the aerial conductors by an operator after standing in an insulating bucket vehicle, and then placing the aerial conductors into an insulating hanging bracket of the insulating wire lifter one by one; erecting an insulating clamp spring of the hanging bracket, thereby preventing the aerial conductors from dropping from the insulating hanging bracket; starting the crane and slowly upward lifting the insulating wire lifter for not less than 400mm, thereby being capable of replacing the cross arm under an electrified running condition of the line. Compared with the prior art, the electrified repairing method provided by the invention has the following beneficial effects: the difficulty that a needle type insulator and a conductor cross arm cannot be replaced by utilizing the insulating bucket vehicle under an electrified condition is solved, the loss of electricity-utilizing enterprises caused by temporary power outage is reduced and the power supply reliability and the power sale quantity are greatly increased.

Description

technical field [0001] The invention relates to the field of live repair of overhead conductors of power lines, in particular to a repair method for live replacement of pole cross arms and pin insulators and an insulation lifter for overhead conductors of 10kV lines. Background technique [0002] In the 1950s, my country pioneered the live work of 3.5kV distribution lines. With the development of the economy, live work has become a conventional technical means to ensure social and economic development and people's harmonious and stable life. During the operation of the power supply system, harsh weather and external force damage will have a huge impact on the reliable power supply of the 10kV line. Lightning strikes the tower to cause pin insulator breakdown, and external force damage causes cross-arm deformation of the wires to occur from time to time. Currently, the replacement of cross-arm and There are two methods of pin insulators: [0003] The first method is to repai...

Problems solved by technology

[0003] The first method is to repair the power line, which has the disadvantage of causing power outages for users and enterprises, reducing the power supply reliability of the line, and reducing economic benefits;

[0004] The second method is to use the insulated arm truck to restore the live work. The disadvantage is that the insulated arm truck will be limited by its own load-bearing factors, and it is difficult to lift the overhead wire, and it is impossible to replace the wire cross-arm operation.
