Problems solved by technology

[0004] At present, the insulation cleaning agent used in the market has a low withstand voltage, and generally can only clean 220KV live equipment at the highest
Moreover, this cleaning agent is corrosive to some plastic components and silicone rubber components.
In addition, this kind of cleaning agent on the market volatilizes slowly, and if the cleaning agent is sprayed on the equipment or components to be cleaned, if the volatility is not strong, it will inevitably corrode the components of the equipment to be cleaned, especially plastic and silicone rubber components. Moreover, the charged ions, acids, alkalis, salts, etc. on the components of the cleaned equipment are not completely removed, which affects the cleaning quality

Abstract

The invention relates to an insulation cleaning agent and particularly relates to an ultrahigh-voltage charged insulator cleaning agent and a preparation method thereof. The ultrahigh--voltage charged insulator cleaning agent comprises the following raw materials in percentages by mass: 50-60% of tetrachlorethylene, 20-30% of methylene dichloride, 15-20% of light solvent oil, 1-2% of a penetrant and 0.5-1.5% of a stable agent. When a surface of a high voltage insulator is subjected to integrated pollution, by virtue of the cleaning agent disclosed by the invention, pollutants can be quickly and completely removed and the phenomenon of flashover due to the dampness of pollutants is prevented. Due to the adoption of the cleaning agent, equipment charged by above 500KV can be cleaned, the resistivity of the cleaning agent reaches up to 1*10<11> / 2.5mm or more, no any corrosion to components of cleaned equipment is generated and the volatilization rate, which reaches up to 0.2-0.25mg / min is relatively rapid and the shortcomings of currently available charged insulator cleaning agent are overcome. The preparation method is simple and easily implemented.

Description

technical field [0001] The invention relates to an insulating cleaning agent, in particular to an ultra-high voltage charged insulating cleaning agent and a preparation method thereof. Background technique [0002] Long-term operating power equipment, especially insulators operating online, is affected by environmental factors such as industrial emissions, moisture, oxidation, corrosive gases and natural dust in the atmosphere, and a layer of comprehensive dirt is gradually deposited on the surface . In dry weather, these insulators with dirt on the surface can still maintain a high level of insulation. However, when encountering humid weather such as fog, dew, drizzle, frost, melting ice, and melting snow, the conductive water film will be formed on the surface of the insulator due to the dissolved salts and acids and alkalis in the dirty layer, which will make the Leakage current flows along the surface of the insulator. Due to the influence of factors such as the shape...
