In a natural environment, the high-speed train insulator is easily polluted by metal dust generated by a bow net system and granular dust in the environment, and a pollution layer is formed on the surface of the high-speed train insulator, so that the surface insulativity of the high-speed train insulator is reduced, and the high-speed train insulator is easily polluted and flashed in a humid weather. Pollution flashover can damage electrical equipment and seriously affect the running safety of high-speed trains.
Due to the particularity of the structure and the position of the insulator of the high-speed train, the current anti-pollution flashover measures mainly adopt a cleaning agent for manual cleaning. The currently adopted cleaning agents only need to be of two types: one type is a solvent type cleaning agent, the cleaning speed of the cleaning agent is high, the cleaning efficiency is high, but volatile gases have certain toxicity, the human body can be injured by long-time contact, the combustion is easy, and the potential safety hazard exists in storage and use; one type is a water-based cleaning agent, the cleaning speed of the cleaning agent is low, the cleaning of all insulators is difficult to complete within a certain maintenance time, the cleaning efficiency is low, residues are easy to exist, and secondary pollution of the insulators is caused.

The detergent mainly removes dirt from the surface of the insulator, and comprises three nonionic surfactants A, B and C, the slow release agent mainly prevents the cleaning agent from being sprayed to the parts outside the insulator to corrode the cleaning agent and particularly metal, the solubilizer mainly increases the solubility of the fallen dirt and other components in the cleaning agent in a solution, the metal complexing agent mainly complexes metal ions in the dirt to prevent the dirt from being deposited on the surface of the insulator again, and the pH regulator mainly regulates the pH value of the cleaning agent to control the pH value of the cleaning agent to be below 9; the nanometer material mainly increases the brightness of the insulated and cleaned material and is not easy to be secondarily polluted.

When the insulator is cleaned, the insulator cleaning agent stock solution is uniformly sprayed on the insulator by using a spray can, and after the insulators on a train carriage are continuously sprayed, the sprayed insulators are lightly wiped by using a cleaning cloth according to the spraying sequence. The insulator wiped by the rag is not clean, and needs to be cleaned for the second time according to the cleaning mode, so that the clean standard can be reached.
