Abstract


With economic development , increased air pollution , increase transmission line insulator pollution flashover , in order to avoid or reduce the occurrence of such accidents , the natural filthy filthy the insulator the outer dielectric strength impact the degree is divided into different degrees and under the jurisdiction of the filth of the regional transmission lines drawn into a polluted area maps to guide the choice of insulator insulation level and Polluted Insulator cleaning . Existing polluted area maps drawn according to the manual measurement insulator salt density , the local pollution sources, distribution and meteorological conditions , only a heavy workload , drawing long period of time , and the subjective effects of restricted Figure larger enough scientific and precise . The paper developed insulator leakage current online detection means , through the installation of the line detecting means and the data collected , using the fuzzy theory to establish the the insulator leakage relationship between the current and the unclean degrees , the development of the use of real-time acquisition of the insulator leakage current data formed sewage distribution system Figure polluted area of Henan Province grid dynamic computer maps drawn automatically .
