摘要
适度控制电晕效应,对发展特高压输电非常重要,输电线路污闪严重威胁着电力系统的安全运行。对国内外多种用于电晕监测的方法进行了介绍,分析了其存在的问题。对于新兴的紫外检测系统,重点分析了其与紫外成像法的区别,最后对不同原理的紫外探测器进行了评价。
It is very important to develop extra-high voltage transmission for right control corona effect.Filthy flashover of transimmission line can seriously threaten safety operation of power systems.Many corona monitoring methods for home and abroad are presented.Plenty of short comings in it are analyzed.For the newly developing ultraviolet ray monitoring system,play special stress on analyzing difference from it and ultraviolet ray imagery.Finally,the ultraviolet detectors of the different principles are estimated.
