Abstract
The invention relates to an insulation cleaning agent and particularly relates to an ultrahigh-voltage charged insulator cleaning agent and a preparation method thereof. The ultrahigh--voltage charged insulator cleaning agent comprises the following raw materials in percentages by mass: 50-60% of tetrachlorethylene, 20-30% of methylene dichloride, 15-20% of light solvent oil, 1-2% of a penetrant and 0.5-1.5% of a stable agent. When a surface of a high voltage insulator is subjected to integrated pollution, by virtue of the cleaning agent disclosed by the invention, pollutants can be quickly and completely removed and the phenomenon of flashover due to the dampness of pollutants is prevented. Due to the adoption of the cleaning agent, equipment charged by above 500KV can be cleaned, the resistivity of the cleaning agent reaches up to 1*10<11>/2.5mm or more, no any corrosion to components of cleaned equipment is generated and the volatilization rate, which reaches up to 0.2-0.25mg/min is relatively rapid and the shortcomings of currently available charged insulator cleaning agent are overcome. The preparation method is simple and easily implemented.
Description
Technical field
The present invention relates to a kind of insulation cleaning agent, be specifically related to a kind of overpressured zones electrical isolation clean-out system and preparation method thereof.
Background technology
The insulator of the power equipment of long-time running, particularly on-line operation is subject to Industrial emissions in atmospheric environment, the impact of the environmental factorss such as airborne moisture, oxidation, corrosive gases and natural airborne dust, and surface has deposited the comprehensive dunghill of one deck gradually.The in the situation that of dry weather, these surfaces still can keep higher dielectric level with the insulator of dunghill.Yet, when running into mist, dew, drizzling rain, frost and ice-melt, during the wet weathers such as snow melt, can be due to the dissolved salt in pollution layer at insulator surface, acid-base class is soluble in water and form conduction moisture film, will make like this leakage current flow through along the surface of insulator.Shape due to insulator, the factor impacts such as scantlings of the structure, the current density at its each position, surface is different, can first form arid zones at the larger position of current ratio, the voltage that arid zones carrying is higher, when strength of electric field is enough large, electric current, by the creeping discharge crossing over drying zone, produces local arc.When dirty and dampness is more serious, local arc meets or exceeds criticality, and electric arc will run through the two poles of the earth, and flashover, i.e. pollution flashover occur.
Fast development along with national economy, net capacity and specified defeated voltage range increase substantially, the development of simultaneous industrial or agricultural, the environmental pollution of some areas is also on the rise, and the harm that the pollution flashover accident of power system power transmission and transformation equipment outer insulation causes and financial loss are also day by day serious.
The insulation cleaning agent of using on the market is at present withstand voltage lower, generally the highlyest can only clean 220KV charging equipment.And this clean-out system has certain corrodibility to some plastics components and parts, silicon rubber components and parts.This clean-out system volatilization is slower on the market in addition, if and that clean-out system is sprayed on the equipment of being cleaned or on components and parts volatility is not strong, certainly will to the components and parts that are cleaned equipment, particularly plastics and silicon rubber components and parts have some corrosion, and be cleaned charged ion on the components and parts of equipment, acid, alkali, salt etc. and remove not thoroughly, affect cleaning quality.
Summary of the invention
The object of this invention is to provide a kind of overpressured zones electrical isolation clean-out system, this clean-out system has cleaning fast thoroughly, and to the components and parts that are cleaned equipment, without any corrosion and the advantage faster of volatilizing, the present invention provides its preparation method simultaneously.
