摘　　要：输电线路盐密值测量是划分污秽等级、编制污区分布图、制定防污闪技术措施的唯一定量依据。文章着重讨论了线路盐密测量中测量点选择、测量方法、清洗绝缘子用蒸馏水量等几个问题,提出了改进措施,分析了用盐密度来确定污秽度的局限性。The ESDD eguivalent salt depositdensity measurement of the transmission lines is the unique quantitative basis for the division of pollution classes,the preparation of pollution area graph and development of measures to anti-pollution flashover.This paper focuses on the selection of measurement places,measurement method and the amount of distilled water for cleaning insulators.The improvement measures are proposed.The limitations that the pollution degree is determined by ESDD are analyzed.
