摘要
根据我国电网大面积污闪的历史教训,提出调整我国现行污秽外绝缘设计与运行维护的技术政策,强调有效的防污闪设计应贯彻“绝缘到位,留有裕度”的原则和污秽等级划分标准与污区图的修订应以饱和盐密为依据。
According to the historical experiences of the large-scale pollution flashover in China power systems,this paper presents the suggestionstoadjustthecurrentexternalinsulationdesignstandardsandcleaningrules.Itisemphasizedthattheeffectiveanti-pollutionflashover design should not depend on cleaning and the values of pollution levels,and should make use of the saturated ESDD.
