Environment-friendly cleaning and repairing agent for composite insulator

Abstract

The invention discloses an environment-friendly cleaning and repairing agent for a composite insulator. The environment-friendly cleaning and repairing agent comprises the following components in percentage by weight: 20-60% of a main cleaning agent, 10-20% of a nonionic surfactant, 5-10% of a penetrating agent, 0.5-1% of a protective agent, 5-10% of a fluorinating agent and the balance of water.With the synergistic effect of the components, the composite insulator cleaning and repairing agent product is high in cleaning capacity without influencing the insulating property or damaging the environment and can perform surface repairing on aged silicone rubber of the composite insulator in normal operation and is an efficient and environment-friendly composite insulator cleaning and repairing agent.

Description

technical field [0001] The invention belongs to the technical field of cleaning agents for electric equipment, and in particular relates to an environment-friendly cleaning and repairing agent for composite insulators. Background technique [0002] The insulators used in the early power industry were made of ceramic or glass. In the 1980s, my country began to develop composite insulators. Due to its excellent pollution flashover resistance, it has been widely used in most heavily polluted areas and many new transmission lines. According to statistics, the amount of composite insulators used in China's grid-connected operation has accumulated more than 7 million pieces (as of 2014, voltage levels of 110kV and above), accounting for the total number of composite insulators in operation in the world (as of 2013, composite insulators of voltage levels of 50kV and above The number has exceeded 20 million) with a large proportion, and it is currently the country that uses the most...

Problems solved by technology

[0004] CN102660410B discloses a cleaning agent for surface contamination of RTV paint insulators, which mainly includes at least two of disodium edetate, sodium glycolate, sodium oxalate and sodium gluconate, sodium polyacrylate, dihydroxyethylidene diphosphonate Sodium, surfactant alkylphenol polyoxyethylene ether, penetrating agent fatty alcohol polyoxyethylene ether, which has a strong ability to remove pollution, but is prone to ionic compound residues, reducing insulation performance

CN105296244A discloses a charged cleaning agent for insulators, which mainly includes: solvent dimethyl carbonate, cosolvent ethylene glycol derivatives, nonionic surfactant, abrasive nano metal oxide, diffusing agent dichloromethane, builder N -Alkylpyrrolidone, stabilizer coconut oil diethanolamide and polymethylsiloxane, mainly for stains in high salinity, high industrial pollution environment, but the abrasive used may also cause damage to the surface of the insulator

CN106190618A discloses a live insulating cleaning agent for high-voltage equipment, which mainly includes alkyl polyglucoside, nonylphenol polyoxyethylene ether, JFC penetrant, light aromatic hydrocarbon naphtha light solvent, polyorganosiloxane, OP Emulsifier, strong permeability, but easy to stick to high-pressure equipment after cleaning, causing operation risk

[0006] To sum up, the current cleaning agents have some deficiencies, such as containing non-environmentally friendly ingredients, causing damage to the surface of the insulator, and the residual cleaning agent will reduce the insulation performance, etc., and the most important thing is that the existing cleaning agents only target the surface of the insulator Dirty cleaning, no attention paid to surface restoration of composite insulators after cleaning
