基于局放重症监测技术在750kV主变缺陷检测中的应用

Application of PD Severe Monitoring Technology in Suspended Discharge Defect of 750kV Main Transformer

本文中作者介绍了一起基于局放重症监测系统在某750kV主变压器悬浮放电缺陷局放检测及定位的应用案例,并通过试验及检查,证明了局放重症监测系统对发现主变悬浮放电缺陷的及时性和准确性。

Based on local discharge critical monitoring technology, the application case of local discharge detection and localization of suspension discharge defect in a 750kV main transformer is introduced by the authors in this paper. Through the power failure diagnosis test and the main transformer back factory disintegration,the timeliness and accuracy of the local critical care monitoring system in detecting the suspension discharge defects of the main transformer are proved.
