摘要
阐述了带电水冲洗的基本原理及国内外的发展历程。通过对水柱绝缘特性和绝缘子在各级人工污秽情况下绝缘特性的试验研究,采用红外成像和紫外成像等手段进行分析,明确了500 kV输变电设备可以进行带电水冲洗,并且在此基础上建议针对不同类型的设备采用不同的冲洗方法。
The basic principle and developing history of live-line water washing for electric transmission and transformation equipment are introduced. By means of experimental investigation on the insulation characteristics of water column and electrical insulator under various conditions of artificial contamination, the infrared image and ultraviolet image were adopted for analysis and it is concluded that the live-line water washing is applicable for 500 kV electric transmission and transformation equipment, also it is suggested that different ways of water washing can be used for different types of equipment.
