220kV变压器交接试验放电故障诊断分析与处理

Diagnosis Analysis and Treatment of Discharge Fault in 220kV Transformer Handover Test

本文中作者通过长时感应耐压多种加压方式查找放电源的电气位置,结合超声波局部放电检测技术对放电源进行定位,确定放电部位并分析了放电原因,根据定位结果对变压器进行解体检查,并进行了故障处理。

In this paper, the author finds the electrical position of the discharge power supply through a variety of ways of long-term induction and pressure resistance, and combines the ultrasonic partial discharge detection technology to locate the discharge power supply, determine the discharge position and analyze the cause of discharge.According to the location results, the transformer is disassembled and examined, and the fault treatment is carried out.
