Background technology
The insulator of ultra-high-tension power transmission line and transformer station's on-line operation, surface can deposit one deck gradually from the dunghill of air pollution and floor-dust, the salt electrolyte that wherein contains electric conductivity, when meeting the wet weathers such as haze and ice and snow, pollution severity of insulators thing absorbs moisture, make electrolyte dissolution, ionization in pollution layer, cause the surface leakage current of insulator to increase.When electric field intensity is enough large, will produce shelf depreciation, and even change local arc into, when local arc reaches critical conditions, electric arc runs through the two poles of the earth, causes flashover.
For fear of the generation of grid pollution flashover accident, need to detect surface filth degree and the dielectric level of insulator, be mainly the measurement of salt density and gray density, to determine whether cleaning or to change porcelain bobbin insulator.Yet traditional detection method offline inspection that insulator need to be had a power failure, implements difficulty large, real-time is poor, has affected the normal safe operation of electrical network.

(1) equivalent salt density method generally need to be torn insulator open ground from shaft tower and even transported to testing laboratory and measure, and in the process of dismounting or transportation, the dunghill of insulator surface is blamed and exempted from because of scraping partial loss, to cause measurement result inaccurate;
(2) equivalent salt density method need to wash down the filth of insulator surface, is a kind of destructive test method, cannot carry out long term monitoring to the contamination accumulation characteristics of same insulator;
(3) equivalent salt density method measurement salt is close need to have a power failure to circuit or transformer station, expend a large amount of human and material resources;
(4) there is equivalence question in equivalent salt density method;
The on-line monitoring ratio juris of the on-line monitoring method leakage current of leakage current is to gather insulator along surperficial leakage current by special drainage system card, measure in real time online the leakage current of insulator chain on transmission line of electricity, try to achieve as calculated peak averaging value, peak maximum and the heavy current pulse number of one section of cycle internal leakage electric current.The mode that adopts wireless transmission to combine with wire transmission, upload the data to data analysis master station, uses expertise and self-learning algorithm to carry out aggregation of data analysis, and the contamination situation of Bing Duigewu district insulator is made assessment.But there are various shortcomings:
(1) leakage current method has high requirements in monitoring of environmental, must more than 75% use in relative humidity, so this equipment is little applicable for northern area;
(2) leakage current method due to rainwater, can stop the generation of insulator pulse current, so must not tested in the rain;
(3) consider electromagnetic radiation strong in transformer station, the pollution level of the same inapplicable judgement of leakage current method or verification transformer station inner insulator;
(4) the more important thing is that leakage current method cannot monitor in real time salt ciphertext data accurately.
