Description

technical field [0001] The invention relates to the prediction of insulator pollution, and more specifically, to a method and equipment for predicting insulator pollution based on weather and other factors. Background technique [0002] In the power grid, dust, sea salt and other substances in the air will form pollution on the insulator, and the existence of pollution is the main reason for the leakage of the insulator and the flashover of the insulator. Especially in coastal areas, due to the existence of sea salt, a large number of accidents caused by flashovers occur every year. This is one of the main factors causing power grid losses. It takes a lot of manpower and material resources to prevent the occurrence of insulator flashovers every year. [0003] In order to reduce the occurrence of flashover caused by insulator pollution, anti-pollution flashover paint can be used to enhance the anti-pollution ability of insulator strings, which can delay the occurrence of acci...

Problems solved by technology

However, the existing polluted area distribution is usually determined according to the location of the line (such as the distance from the coastline, industrial pollution areas, etc.) There will be a large error in the actual situation, which will lead to incomplete cleaning of the insulator contamination, and cannot prevent the flashover of the insulator well

[0005] Existing technology can also use x-ray based measuring devices to detect the salt density and dust density on the insulator, and then send the measurement data back to the data center to determine the distribution of contaminated areas, but this method is difficult to be widely used in the industry , the reason is: the cost of installing this instrument on the line is very high; data transmission needs to rely on wireless network, which is expensive; it cannot work for a long time in the harsh environment of high humidity and high salinity in the coast
