Problems solved by technology

However, in practical applications, compared with ODS cleaning agents, hydrocarbon cleaning agents have a higher boiling point and a lower flash point (generally around 60°C), which greatly reduces the drying speed of the workpiece after cleaning, and the lower flash point Increases the fire hazard during use
In the prior art, the above problems are mainly improved by adding appropriate additives, such as patent CN102191141A, by adding some alcohol, ester and ether additives, the modified hydrocarbon cleaning agent not only has strong cleaning power, high KB value, and aniline point Low, can clean polymer pollutants such as wax, resin, ink, rosin, etc., but the flash point of the cleaning agent is generally low, not suitable for cleaning live equipment

Abstract

The invention discloses a composite cleaning agent for electrified insulation equipment. The composite cleaning agent comprises: 85-95 weight parts of a hydrocarbon cleaning agent, 5-10 weight parts of a compound surfactant and 5-15 weight parts of a stabilizer. The composite cleaning agent provided by the invention has a wide application range, and can be used for cleaning insulation electrical equipment of various voltage classes. Also the composite cleaning agent has no harm to ozone and has small fire hazard, is volatile after use, and has no residual liquid.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to a composite hydrocarbon cleaning agent with good fireproof performance. Background technique [0002] Live insulation equipment is often polluted by industrial dirt or natural salinity, flying dust, bird droppings, etc. In dry conditions, the resistance of these pollutants is very large, but when the atmospheric humidity is high, the dirt on the surface of the insulating equipment is wetted, and its surface conductance and leakage current increase sharply, which significantly reduces the flashover voltage of the insulating equipment. It may even flashover under the working voltage, affecting the safe operation of the power system. Compared with traditional methods such as dry cleaning, air blowing and water washing, the use of chemical cleaning agents to carry out electrified chemical cleaning of power grid equipment can effectively solve this problem.
