摘要

近幾年來，由於維護技術的進步，特別是儀器系統和各種設備檢測技術方法的突破，使得早期由事後維護保養的概念，轉變為生產保養和預防保養維護，目前更以預知維護為主流，而以預知維護取代保養為維護設備之最終目的。
本文利用紅外線熱影像和超音波技術對電力設備進行非破壞性檢測，藉以預知設備是否異常，來提升電力設備維護之安全要求。非破壞檢測和傳統破壞性檢測不同，非破壞檢測注重於預防性檢測以及缺陷檢測，傳統的破壞性檢測則偏重於材料性質檢測，尤其是與公共安全相關的電力設備之檢測，常須應用破損分析或資料重建。
由結果得知紅外線熱影像對電力設備內部故障檢測較不明顯，所以本文結合超音波技術來對電力設設備內部故障進行檢測，兩者相輔相成，如此一來將可防止大規模的停電及公安事故。

Recently, due to the improvement of maintenance technology, especially the breakthrough of equipment systems and equipment measuring technology, the traditional ideas of maintenance has transferred to productive and preventative maintenance. Nowadays, predictive maintenance is the main stream, and the final purpose of equipment maintenance is the saving of maintenance.
This thesis presented the hot image technology of infrared and ray ultrasonic to carry on non-destructive measuring to the electric equipments, use to foresee whether equipments are unusual, to improve the safe demand for predictive maintenance of electric equipments. The non-destructive measuring is different from the tradition destructive measuring. It does not destroy and measure and pay attention to preventative measuring and defect to measure, traditional destructive measuring focus on material nature to measure, especially the measuring with public and safe and relevant electric equipments, must often use the damage to analyze or the data are rebuilt.
According to the consequence, the measuring of infrared thermograph technology to the inner breakdown of electronic equipments is less conspicuous. Therefore, in this essay, I combine the ultrasonic for the detection of the inner breakdown of electronic equipments so as to prevent serious power failure and public safety events.
