摘要
现场运行经验表明 ,为了保证氧化锌避雷器的安全运行 ,必须对氧化锌避雷器进行长期的在线监测。现有的监测方法以监测阻性泄漏电流效果最佳 ,对阻性泄漏电流的效果取决于测量精度的高低。如何提高阻性泄漏电流测量精度 ,始终是这一领域所关注的焦点问题。文章对近年来国内外发表文献的研究动态加以综述。
It is obvious that the state of Metal Oxide Arresters (MOA) on line have to be detected in order to prevent them from abnormal work, especially the resistive component of the continuous leakage current to be detected, which is a good indicator of the MOA condition. Several ways of monitoring the state of a MOA in service have caused some measurement error unexpected. The problem has been highlighted by worldwide researchers in the field because of its great value on both academic theory study and practical application. In this paper, some research results coming from the last documents in the field have been collected.
