Study And Application On Prevent Pollution Flashover In Changzhi Electricity Network

In recent years, with the aggravation of the air pollution, improvement of the voltage of transmission of electricity, The accident flashes corruptly to increase to some extent, ,so it is significant to do research into the mechanism and characteristics of flashover, and by compare technical with economic, measures can be taken according to prevent flashover in changzhi area..because the occurrence on electrical equipment will have a grave effect on the safe operation of electrical network.So this article is mainly concerned about the process, and mechanism of flashover, the factors affects flashover voltage, , measures taken to prevent it, and its preventive effect in Changzhi area.Changzhi Branch of Electricity Power Company has used the approaches above to monitor, and prevent flashover. Under the suitable management and measures, with the salt density monitoring as the major method, The distribution of Polluted Areas and Distribution of Pollution Sources have been plotted serving as the basis for prevention. Cleanup, washing, petticoat, RTV coatings and Distance enlargement are adapted as the major means, but for the electricity output lines, cleanup, shift and adjustment as the measures, which have effectively prevented flashover and secure the safe operation of the equipment.
