preparation example Construction
[0029] The preparation method of anti-fouling flash coating scavenger of the present invention comprises the steps:
[0030] Step a) Mix boron trifluoride diethyl ether, cosolvent, penetrant and thickener in a ratio of 5-20:5-20:5-15:3-8, and stir evenly. The ratio is preferably 10-16:10- 16:8~12:5~8, it is preferable to add boron trifluoride diethyl ether, cosolvent, penetrant and thickener in sequence and in proportion, at 16°C to 25°C;
[0031] Step b) filtering the mixed solution to obtain the desired anti-fouling flash coating remover after filtering out impurities.

The invention provides a soluble anti-contamination flashover coating scavenging agent, which comprises the following components: boron trifluoride diethyl etherate, a cosolvent, a penetrating agent, and a thickening agent, wherein the weight ratio of the boron trifluoride diethyl etherate to the cosolvent to the penetrating agent to the thickening agent is 5-20:5-20:5-5-15:3-8. The method for preparing the anti-contamination flashover coating scavenging agent comprises the following steps of: a) mixing the boron trifluoride diethyl etherate, the cosolvent, the penetrating agent, and the thickening agent in the ratio of 5-20:5-20:5-5-15:3-8; and b) filtering the mixed solution. The anti-contamination flashover coating scavenging agent has the advantages of 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 antifouling flashover coating remover and a preparation method thereof. Background technique [0002] When the surface of electric porcelain on transmission lines and equipment in the power industry is polluted by solid, liquid or gaseous conductive substances, especially when it encounters humidification such as fog, dew and drizzle, the conductance of the polluted layer increases rapidly, and the leakage current increase, resulting in 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 pollution flashover of insulators. [0003] Pollution flashover of equipment will seriously affect the safe operation of the power system, and when equipment pollution flashover occurs, the succes...
