Insulating cleaning agent capable of achieving live cleaning of high-voltage equipment

Abstract

The invention discloses an insulating cleaning agent capable of achieving live cleaning of high-voltage equipment. The insulating cleaning agent comprises, by weight percentage, 60-75% of trifluorotrichloroethane, 5-20% of nonyl phenol polyoxylethylene ether, 3-10% of JFC penetrant, 1-5% of light aromatic hydrocarbon naphtha solvent, 0.5-1% of polysiloxane and 2-10% of OP emulsifier. Compared with cleaning agents in the prior art, the cleaning agent has the advantages that the cleaning agent is high in insulating performance and applicable to power equipment above 220kV, an extremely high insulating value on the surface of an insulator can be kept during and after cleaning, and safety cleaning can be achieved under the situation that the normal operation of the high-voltage equipment is unaffected; the cleaning agent is high in permeability and can be adhered to high-voltage equipment, the cleaning agent which permeates for a certain period of time and becomes dry can be removed, stubborn dirt on the high-voltage equipment can be well cleaned, and fast cleaning and cleanliness can be achieved.

Description

technical field [0001] The invention relates to the field of cleaning agents, in particular to a charged insulating cleaning agent for high-voltage equipment. Background technique [0002] High-voltage power equipment is exposed to the air for a long time. Affected by environmental factors such as air pollution and natural dust, its surface inevitably adheres to solid, liquid and gaseous dirt particles, and generally has a certain degree of conductivity and hygroscopicity. Pollution flashover will occur, causing large-scale power outages and causing major losses to local production and life. [0003] Pollution on the surface of high-voltage power equipment, wetting of the surface of polluted high-voltage power equipment, and voltage are the three necessary conditions for pollution flashover to occur. Therefore, taking countermeasures against any of the factors can achieve the purpose of preventing pollution flashover. The main measures taken by the power sector over the yea...
