污区分布图在电网防污闪技术管理中的应用

Application of Pollution Distribution Map in Power Grid Anti Pollution Flashover Technology Management

阐述线路外绝缘设计,根据污区分布图确定污区等级,综合气候环境、污源、现场污秽度、污闪故障以及运行经验,修订区域电网污区分布图,并给出了污区分布图应用原则。

This paper describes the external insulation design of the line,determines the grade of the pollution area according to the distribution map of the pollution area,and revises the distribution map of the pollution area of the regional power grid by integrating the climate environment,pollution sources,on-site pollution degree,pollution flashover fault and operation experience,and gives the application principles of the distribution map of the pollution area.
