摘要
输电线路外绝缘污秽等级的划分关系到输电系统运行安全。对江苏电网双伞形绝缘子饱和盐密与灰密进行分析,得到饱和系数、不均匀系数和灰密比,通过典型环境的饱和盐密与灰密测量,确定其现场污秽度等级,提出了修订江苏电网污区分布图的方法。
Pollution classification for the external insulation of transmission lines directly affects system security. The saturated equal salt deposit density （ESDD） and the non-soluble deposit density （NSDD） of the double-umbrella type insulator in Jiangsu Power Grid are analyzed, and the saturation coefficient, the asymmetry coefficient, and the NSDD/ ESDD ratio are obtained. The site pollution severity （SPS） of typical environments can be identified through measurement of saturated ESDD and NSDD. Methods for modifying the pollution plot of Jiangsu Power Grid are also proposed.
