Problems solved by technology

These cleaning agents can be charged and cleaned, but when used to clean high-voltage insulators, the cleaning agent has poor penetration performance, and the cleaning effect on insulators with serious pollution is poor; and for cleaning agents mainly based on trichlorethylene, the boiling point is higher. Poor volatility, easy to remain on the surface of insulators and cause accidents

Abstract

The invention relates to a high-voltage insulator surface electrified cleaning agent which comprises the following components in percentage by weight: 75-85% of detergent builder, 5-10% of nonionic surfactant, 1-5% of penetrating agent, 0.5-10% of organic solvent and 0.5-1% of protective agent, wherein the detergent builder is trichlorotrifluoroethane, and the protective agent is silicone oil. The cleaning agent has small surface tension, strong foul cleaning capacity on a high-voltage insulator, good permeability, insulation performance, high-voltage resistance, and good stability, is easy to volatilize and not easy to burn and non-toxic.

Description

technical field [0001] The invention belongs to the field of fine chemicals, in particular to a high-voltage insulator charged cleaning agent. technical background [0002] High-voltage insulators, exposed to the air for a long time, are affected by environmental factors such as air pollution and natural dust. Solid, liquid and gaseous dirt particles are inevitably adhered to the surface, and generally have certain conductivity and hygroscopicity. Under the joint action of weather conditions such as fog, dew, rain and snow, the insulation level of the insulator will be greatly reduced, thereby increasing the leakage current on the surface of the insulator, so that pollution flashover may also occur under the working voltage, causing power outages. With the development of electric power science and technology, the possibility of partial faults causing the collapse of the power grid is very small, but when a large number of lines trip and the power generation and substations c...
