Method for mounting anti-waving spacers on 66-kilovolt power transmission hot-line

Abstract

The invention relates to the field of hot-line jobs of power transmission lines, in particular to a method for mounting anti-waving spacers on a 66-kilovolt power transmission hot-line. The method is characterized in that an operator fixes one end of an anti-waving spacer on a lower lead of the power transmission line by means of equal potential working, and fixedly connects the other end of the anti-waving spacer with an intermediate lead by means of middle potential working. Compared with the prior art, the method has the advantages that the method is safer than a common hot-line working method, particularly middle lead equal potential working is substituted by middle lead middle potential working, hot-line working operators can be protected better, and the method is of significance to prevention of ice coverage and wind waving disasters and guaranteeing safe and stable running of the power transmission line; power outage time limit is freed, and operation is convenient and quick; and power outage mounting time can be shortened by 70%, power sale quantity of power supply enterprises is increased, power supply reliability is improved, service quality of the power supply enterprise is improved, and remarkable social benefits are obtained.

Description

technical field [0001] The invention relates to the field of live work on transmission lines, in particular to a live installation method for anti-galling spacers on a 66 kV transmission line. Background technique [0002] Since the beginning of winter in 2009, affected by severe weather such as strong winds, rain, snow and freezing, the transmission lines in the power supply area of ​​the State Grid Corporation of China have experienced seven large-scale dances, causing huge economic losses. Through the theoretical calculation and statistical analysis of line galloping, it is proved that the key link of "the center line must move" of the 66 kV double-circuit line on the same tower, and the principle of "controlling the middle and lower line galloping" is established. The best way is to install anti-galling spacers to thoroughly Cut off the dancing tripping path. [0003] In the past, the method of installing anti-galling spacers, one is power-off installation. With the dev...

Problems solved by technology

[0003] In the past, the method of installing anti-galling spacers, one is power-off installation. With the development of society and the company's own requirements, improving the reliability of power supply has attracted more and more attention from the society and power supply companies. Power-off installation is not completely applicable: another The second is live work, using the equipotential method to install anti-galling spacers. However, due to the short distance between the 66kV phases, the distance between the neutral line and the downline does not meet the requirements of the "State Grid Corporation Electricity Safety Work Regulations", and the equipotential of the spacers cannot be carried out.
