Embodiment Construction

[0014] The specific implementation of the charged water flushing method for 220kV and below transmission line insulators of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] figure 1 It is a flow chart of the 220kV and below transmission line insulator charged water flushing method of an embodiment, including the following steps:

[0016] Step a. Ground the live water flushing device of the mobile transmission line, set the water resistivity of the water and adjust the pressure of the water gun.

[0017] Specifically, after the delivery vehicle arrives at the job site, the ground staff checks the situation of the live water flushing device of the mobile transmission line, first grounds the delivery vehicle, and then lays the water pipe under the iron tower under the control of the hydraulic device to test the water quality of the water. Resistivity and adjust water gun pressure. Preferably, the water resistivity o...

Abstract

The invention provides a 220 KV and below 220 KV electric transmission line insulator electrification water washing method. The method mainly comprises the steps of setting the water resistivity of water and adjusting pressure of a hydraulic giant; judging the wind direction and wind power on a tower and adjusting the length of a water column according to the wind direction and the wind power; placing the hydraulic giant at a given position and washing triphase insulators of 220 KV and below 220 KV electric transmission lines in sequence from bottom to top; washing insulator chains on the downwind side firstly and then washing insulator chains on the weather side during insulator chain washing, and washing piece by piece from bottom to top and washing by starting from the wire side in sequence for suspension insulator chains; and judging whether phenomena of sewage dripping and partial arcing striking appear for washed insulators, and rewashing corresponding insulators if the phenomena appear. The 220 KV and below 220 KV electric transmission line insulator electrification water washing method enables electrification water washing to be achievable for most of the 220 KV and below 220 KV electric transmission lines, line outrage is reduced, pollution flashover is avoided, safety and stability of power grids are ensured, and good economic and social benefits are created.

Description

technical field [0001] The invention relates to anti-fouling flashover technology for high-voltage transmission lines, in particular to a method for flushing charged water insulators of transmission lines of 220kV and below. Background technique [0002] With the rapid development of industrial economy and urban construction, higher and higher requirements are put forward for the continuity and quality of power supply, to prevent pollution flashover of transmission lines, prevent large-scale power outage accidents in the power grid, and ensure safe and stable operation of the power grid and reliable power Supply is very important. However, transmission line equipment has been exposed to nature for a long time, especially in industrial areas, coastal areas and saline-alkali areas. It is affected by industrial waste gas, sea water or natural saline-alkali, dust, and usually forms a certain degree of pollution on the surface of its insulators. These pollutants containing salt,...
