Abstract

The invention relates to a method for live cleaning of a contaminated insulator with high-temperature water vapor doped with alkanolamide. The method comprises the following steps of: firstly adding the alkanolamide accounting for 10% of total volume into water for cleaning to obtain mixed liquid, then placing the mixed liquid in an electric heating device, and starting a power supply of the electric heating device for heating the mixed liquid, wherein the heating temperature does not exceed 150 DEG C; and then sending the obtained high-temperature water vapor doped with the alkanolamide from a vapor compressor to a spray gun via a gas pipe, directly spraying to the contaminated insulator at the speed above 100m / s under the action of the vapor compressor, and cleaning three to four times from bottom to top so as to realize the live cleaning of the contaminated insulator. According to the method disclosed by the invention, the live cleaning problem of the contaminated insulator with high equivalent salt deposit density, high non-soluble deposit density and heavy oil dirt can be effectively solved, the safety and reliability in operation of electric power equipment can be ensured, and the method has the advantages of good cleaning effect, high speed, water saving, labor saving and low cost.

Description

technical field [0001] The invention relates to a method for cleaning dirty insulators, in particular to a method for charging and cleaning dirty insulators doped with high-temperature water vapor and alkanolamide. Background technique [0002] Insulators are an important part of overhead transmission lines, used to electrically insulate the conductors at high potential and the towers at low potential and connect them mechanically. Insulator pollution is a large-scale regional problem. Natural salinity, flying dust, bird droppings or industrial pollution are deposited on the surface of operating insulators. The sharp decline in the external insulation capacity of the insulator causes a flashover, which affects the safe operation of the system. [0003] Once an insulator pollution flashover accident occurs, it will cause tripping of lines and substations, resulting in regional power outages to varying degrees. Pollution flashover accidents in the power grid are second only ...
