Cleaning protective agent for insulator of high-speed rail train

Abstract

The invention discloses a cleaning protective agent for an insulator of a high-speed rail train. The cleaning protective agent for the insulator of the high-speed rail train is liquid and comprises the following components in percentages by weight: a detergent, a corrosion inhibitor, a solubilizer, a metal complexing agent, a pH value regulator, a nano material and deionized water. The detergent is a multi-component combined nonionic surfactant and accounts for 1-2.5%, and the corrosion inhibitor accounts for 0.3-1%, the solubilizer accounts for 3-9%, and the metal complexing agent accounts for 0.1-0.8%, the proportion of the pH regulator is determined according to the actual situation, the nano material is solid nano particles and accounts for 0.01-3%, and the rest is the deionized water.By the cleaning machine, the insulator is bright as new after being cleaned, a layer of protective film is formed on the surface of the insulator, so that the insulator is not easily secondarily polluted, and the secondary cleaning time is prolonged.

Description

technical field [0001] The invention relates to the technical field of cleaning insulators for high-speed trains, in particular to a cleaning and protecting agent for high-speed train insulators. Background technique [0002] The insulator is a key component of the high-speed rail train contacting the grid support and suspension device. It is located on the top of the high-speed rail train and plays the role of electrical isolation between the point part and the insulating part of the suspension device and the support for the suspension device. In the natural environment, the insulators of high-speed trains are easily polluted by the metal dust produced by the pantograph-catenary system and the granular dust in the environment, forming a dirty layer on the surface, reducing the surface insulation, making it easy to Dirt flash occurs. Pollution flashover will damage electrical equipment and seriously affect the operation safety of high-speed trains. [0003] Due to the spec...

Problems solved by technology

There are only two types of cleaning agents currently used: one is solvent-based cleaning agents, which are fast in cleaning speed and high in cleaning efficiency, but the volatilized gases are toxic to a certain extent, and long-term contact will cause harm to the human body. It is easy to burn, and there are great safety hazards in storage and use; one is water-based cleaning agent, which has a slow cleaning speed, and it is difficult to complete the cleaning of all insulators within a certain maintenance time, and the cleaning efficiency is not high , easy to have residues, causing secondary pollution of insulators
