[0030] The preparation method of the anti-pollution flashover coating scavenger of the present invention includes the following steps:
[0031] Step a) Mix the main solvent, co-solvent, penetrant and thickener in a ratio of 20~70:20~70:10~50:3~8, and stir evenly. The main solvent is a molecular weight of 400~500. Low-molecular-weight halogenated hydrocarbons, the ratio is preferably 30-50:30-50:15-35:5-8, and it is preferable to add the main solvent, cosolvent, penetrating agent and thickening agent in sequence in sequence, at 16℃~25 ℃;
[0032] Step b) filtering the mixed solution to obtain the desired anti-fouling flashover coating scavenger after filtering out impurities.

The invention provides a swelling anti-contamination flashover coating scavenging agent, which comprises the following components: a main solvent, a cosolvent, a penetrating agent, and a thickening agent, wherein the weight ratio of the main solvent to the cosolvent to the penetrating agent to the thickening agent is 20-70:20-70:10-50:3-8; and the main solvent is low molecular haloalkane with themolecular weight of between 400 and 500 or the low molecular halohydrocarbon with the molecular weight of between 400 and 500. The method for preparing the anti-contamination flashover coating scavenging agent comprises the following steps of: a) mixing the main solvent, the cosolvent, the penetrating agent, and the thickening agent in the ratio of 20-70:20-70:10-50:3-8, wherein the main solvent is the low molecular halohydrocarbon with the molecular weight of between 400 and 500; and b) filtering the mixed solution. The anti-contamination flashover coating scavenging agent has the advantagesof simple preparation method, convenient use, good scavenging effect on the anti-contamination flashover coating, and certain viscosity, can effectively avoid the harm to human bodies due to volatilization, splash and drippage of the scavenging agent in the using process.
Description
Technical field [0001] The invention relates to the field of power transmission lines, in particular to an anti-pollution flashover coating scavenger and a preparation method thereof. Background technique [0002] Electric porcelain surfaces on transmission lines and equipment in the power industry are contaminated by solid, liquid or gaseous conductive materials, especially when wetted by fog, dew and drizzle, the conductivity of the pollution layer increases rapidly, and leakage current Increase and produce partial discharge. Under the operating voltage, the partial discharge on the surface of the ceramic part will develop into an arc flashover, which is called pollution flashover. Air pollution and moisture condensation are the direct causes of insulator flashover. [0003] Pollution flashover of equipment will seriously affect the safe operation of the power system, and when the equipment flashes, the success rate of reclosing is very low, so it often causes a large-scale pow...
