Problems solved by technology

[0012] However, the anti-bird measures such as laser bird repellent, ultrasonic bird repellent, and artificial bird repellent are not effective; prolonging the unbalanced protection action time of the AC filter may cause the risk of avalanche breakdown of the capacitor due to overvoltage, so it is not recommended to use; These technical measures are either unfeasible to implement on site, or have been proved to be unsatisfactory, and cannot really play a role in preventing bird damage
[0013] Therefore, there is an urgent need for a new technical measure to solve the problem of bird damage tripping caused by the invasion of flying birds or foreign objects in the AC and DC filters, and to achieve the harmony between the safe operation of power facilities and the living environment of birds

Abstract

The present invention relates to the technical field of insulating coatings, in particular to a bird-proof insulating coating for AC and DC filters, coatings and preparation methods thereof, which solves the problem that in the prior art, when birds enter and move in the capacitor of the filter, it is very easy to cause The short circuit between the voltage difference parts of the equipment leads to the unbalanced current protection action of the capacitor, which causes the filter to trip. , fulvic acid, aluminum oxide, calcium carbonate and silane additives. The present invention sprays insulating paint on the AC filter tower to insulate and cover the charged capacitor casing, frame, pipe mother, voltage equalizing ring and other accessories, and forms an insulating barrier between the components of the filter with voltage difference. After the bird enters, once a bridge between different potential points occurs, no short circuit occurs, and the insulation of all charged parts of the filter tower is realized, which can withstand the voltage difference when the bird is short-circuited.

Description

technical field [0001] The invention relates to the technical field of insulating coatings, in particular to an insulating coating for preventing bird damage of an AC-DC filter, a coating and a preparation method thereof. Background technique [0002] Converter stations and substations need to be equipped with different numbers of filters for power transmission. When birds enter the filter capacitors, it is very easy to cause a short circuit between the voltage difference parts of the equipment, which will cause the unbalanced current protection of the capacitors to operate, causing the filter to trip. After the filter trips, it is necessary to measure the capacitance value of the capacitors one by one and the bridge arm capacitance measurement of the capacitor tower, etc., and the maintenance work is very heavy. If the filter bank cannot meet the absolute minimum filter requirements at this time, it will cause the power drop of the DC system to cause load loss, and even lea...
