摘 要: 超聲波和暫態(tài)對地電壓TEV 檢測技術(shù)是開關(guān)柜局部放電檢測的兩種常用手段。在故障診斷時應(yīng)用了這兩種檢測手段基礎(chǔ)上還引入了紫外成像檢測技術(shù),并對這三種檢測方法進(jìn)行分析比較。通過實際案例分析表明,紫外成像檢測技術(shù)在開關(guān)柜故障診斷可以提供有價值的參考數(shù)據(jù),是其他兩種檢測技術(shù)的有效補(bǔ)充。

Abstract: 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 technology can provide valuable reference data for switch cabinet fault diagnosis, to be an effective supplement for the other two test technologies.
Key words: switch cabinet; ultrasonic; transient earth voltage; ultraviolet imaging test technology
