摘要
变压器、GIS、电缆等电气设备长期运行中绝缘劣化可能导致局部放电,对局部放电进行检测可以保证电网长期安全可靠运行。首先介绍了多种不同的局部放电检测方法,分析不同方法的优缺点,在此基础上,介绍了局部放电的抗干扰措施。
The insulation degradation of transformers,GIS,cables in long-term operation may result in partical discharge.For the partical discharge test,we can ensure electric networks to operate safetly and reliably.Many different partical discharge methods are presented.Analyse merits and demerits of the different method.For this,the anti-interference measures of the partical discharge are presented.
