Embodiment Construction

[0022] The specific implementation manners of the present invention will be described in detail below in conjunction with specific conditions and accompanying drawings.

[0023] In concrete implementation, the present invention is realized by the following steps:

[0024] 1. Prepare high-voltage insulation cleaning agent, which is calculated by weight percentage: solvent naphtha 40-50%, light solvent oil 7-11%, No. 25 transformer oil 40-50% and penetrating agent 0.5-1.5% % mixed together; the light solvent oil is 200# solvent oil or 400# solvent oil; the penetrating agent is also called wetting agent or surfactant, which is methyl pyrrolidone, sulfonated oil, pull Open powder BX or a kind of soap;

[0025] 2. prepare cleaning solution, above-mentioned high-voltage insulation cleaning agent and solid epoxy resin sand are mixed together with weight ratio 40:1 and make, and described epoxy resin sand is pulverized by epoxy resin, crosses 100 mesh sieves, Then rinse the epoxy re...

Abstract

The invention relates to a gas-liquid mixed sandblasting insulation method for cleaning a high-voltage electrified insulator, which can effectively solve the problem of cleaning the high-voltage electrified insulator. In the method, gases and a cleaning agent are combined to clean the high-voltage insulator, and the method comprises the following steps of: preparing a high-voltage insulating cleaning agent; preparing a cleaning solution by mixing the high-voltage insulating cleaning agent and solid epoxy resin sand in a weight ratio of 40:1, fully uniformly mixing the cleaning solution in a mixer, and conveying the cleaning solution to a spray gun through an infusion pump via an infusion pipe; and delivering air to the spray gun through an air compressor via an air filter, spraying the cleaning solution to the high-voltage insulator at a speed of over 100m / s under dual action of the air compressor and the infusion pump so as to clean the high-voltage insulator. The method has the advantages of advancement, simple equipment, good cleaning effect, high speed, safe operation and low labor intensity, and is an innovation for cleaning the electrified insulator.

Description

technical field [0001] The invention relates to electric power equipment, in particular to a method for gas-liquid mixed sandblasting and high-voltage electrified insulation cleaning insulators. Background technique [0002] Insulators are essential for power equipment. Because insulators are exposed to the air, they are easily polluted, and pollution flashover is common. Once pollution flashover occurs, it will affect the safety and normal operation of power transmission equipment. [0003] The so-called pollution flashover refers to the accumulation of conductive pollutants on the surface of line insulators. After being damp in humid weather, the insulation level of the insulator is greatly reduced, and flashover accidents occur under normal operating conditions. The polluting substances on the surface of insulators are generally divided into two categories: [0004] (1) Natural pollution: fine dust floating in the air, salt mist brought by the sea breeze (salt frost form...
