摘要
超声波和暂态对地电压TEV检测技术是开关柜局部放电检测的两种常用手段。在故障诊断时应用了这两种检测手段基础上还引入了紫外成像检测技术,并对这三种检测方法进行分析比较。通过实际案例分析表明,紫外成像检测技术在开关柜故障诊断可以提供有价值的参考数据,是其他两种检测技术的有效补充。
Ultrasonic and transient earth voltage （TEV） test technologies were two common methods to test partial discharge of switch cabinet. In fault diagnosis, these two methods were applied and on this basis, ultraviolet imaging test technology was also introduced. This paper analyzed and compared these three test methods. The actual examples show that the ultraviolet imaging tech-nology can provide valuable reference data for switch cabinet fault diagnosis, to be an effective supplement for the other two test technologies.
