变压器局部放电诊断方法研究

Study on Diagnostic Method of Partial Discharge of Transformers

变压器局部放电监测是保证变压器安全稳定运行的重要手段。对常规脉冲电流法、超声波法、油中气体分析法、特高频法和宽频带脉冲电流法等五种典型的变压器局放电检测方法进行了介绍,并分析了其优缺点。最后给出了不同方法的应用建议。

Partial discharge monitoring of a transformer is an important measure to easure tranformer safety operation. The paper presents five typical transformer partical discharge test methods, such as conventional impulse current method, ultrasonic method, gas analysis method in oil, ultrahigh frequency method and wide-hand impulse current method and an- alyzes their strong and weak points. Finally, the applied suggestions of different method are given out.
