Embodiment Construction

[0021] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] This embodiment is realized by the following method, a 500kV transmission line tension insulator string insulation cleaning method charged cleaning method, including the following steps:

[0023] Step a: Ground the 500kV transmission line insulation cleaning agent live cleaning device, and set the pump pressure on the high-pressure cleaning machine.

[0024] Step b: Connect the cleaning rod to the high-pressure cleaner, and reliably ground the cleaning rod.

[0025] Step c: Adjust the cleaning rod so that the jet nozzle in the arc-shaped insulating cover is aimed at the insulator to be cleaned.

[0026] Step d: Clean at a constant speed from the high-voltage side to the low-voltage side of the tension insulator string of the 500kV transmission line. The shroud and jet nozzle slide over the string of insulators.

[0027] Step e: When cleaning,...

Abstract

The invention relates to a high-voltage electric transmission line pollution-flashover-preventing technology, in particular to an insulation cleaning agent electrified cleaning method for a 500 kV electric transmission line tension insulator string. The insulation cleaning agent electrified cleaning method comprises the steps that a 500 kV electric transmission line insulation cleaning agent electrified cleaning device is connected to the ground, and the pumping pressure is set on a high-voltage cleaning machine; a cleaning rod is connected with the high-voltage cleaning machine, and the cleaning rod is reliably connected to the ground; the cleaning rod is adjusted to enable jet nozzles inside an arc-shaped insulation hood to align at insulators needing to be cleaned; cleaning is conductedfor a round trip at a constant speed from the high-voltage side to the low-voltage side of the insulator string, and the cleaning rod is manipulated to enable the arc-shaped insulation hood to slideon the insulator string; the cleaning rod is quickly rotated during cleaning, thus liquid columns sweep back and forth on the left sides and the right sides of the insulators, and if the abnormal electric discharge phenomenon exists in the cleaning process, cleaning needs to be instantly stopped; and the washing time of one single piece of insulator is 4-6 s and is determined according to the pollution degree. According to the insulation cleaning agent electrified cleaning method, insulation cleaning agent electrified cleaning can be conducted on the 500 kV electric transmission line tension-resistant insulator string, pollution flashover is avoided, and safety and stability of a power grid are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of anti-pollution flashover of high-voltage transmission lines, and in particular relates to a live cleaning method of an insulating cleaning agent for tension insulator strings of 500kV transmission lines. Background technique [0002] Pollution flashover accidents on the external insulation of power transmission and transformation equipment caused by air pollution have caused serious harm to the power system. Pollution flashover accidents will have a great impact on the lives of residents and cause huge losses to factories, seriously affecting the safety of the power system. Reliable operation. Pollution flashover accidents often occur when the atmospheric humidity is high, the insulators are wetted by pollution, and the surface conductance increases sharply, which greatly reduces the flashover voltage of the insulators. In order to prevent pollution flashover accidents, it is particularly important to st...
