| 摘 要： | 大多变压器的损坏和故障都是因绝缘系统的损坏而造成的,对变压器绝缘状况好坏的判断有不少方法。这里介绍一种现场无损检测方法——恢复电压法(RVM)。文章以3台变压器为例,通过测试其绝缘介质的恢复电压,对其绝缘寿命进行了评估。与其他方法相比,恢复电压法更能反映绝缘材料的详细信息,有较好的准确性,更能体现其现场检测的优势。

| Abstract: | Most damage and faults of power transformer are due to something wrong with the insulation system. This paper introduced a detecting method without damage-Recovery Voltage Measurement (RVM). Taken three power transformers as an example,the life of insulation can be estimated through the Recovery Voltage Measurement of insulation medium. Compared with other methods,the Recovery Voltage Measurement is better to know the insulation medium information in detail,which has more accuracy and advantages for detecting on site. |
