摘要:	電力系統穩定供電是社會與經濟發展重要指標，此乃是全世界各國朝向的目標，亦是各國不斷以提升供電穩定及減少事故發生的頻率方向邁進。本研究以台灣北區某變電所電力系統設備事故與維修為例，以平台彙整各類電力事故年報資料輸入Power BI。將斷路器內檢關鍵因子透過80/20法則找出高風險20%與實際內檢紀錄比較，作為採取狀態基準維護方式之依據，以及提供電力相關產業未來維護之參考。本研究發現導入BI工具可視覺化呈現數據，並有效探討分析各類數據與電力事故，以及斷路器接觸子於使用期限內幾乎不會超過接觸子壽命，提供相關產業對於斷路器內檢維護模式採取較適維護方式可維持供電品質及節省維護成本。 ;The stable supply of power systems as a key indicator of development in society and economy not only drives the globe to strive for it but also keeps urging the world to enhance the stable power supply and reduce the failure frequency. This study used the failure and maintenance record of the power systems logged in a substation in North Taiwan as the subject of the study along with a specific platform collecting the data associated with a variety of power system failure in an annual report and inputting them in Power Business Intelligence (Power BI). The key factors of internal inspection of circuit breakers are identified by the 80/20 rule. In other words, this study suggests prioritizing inspection tasks and labor efforts on the 20% portion of higher voltage and more frequent power system failure among all internal inspection record and adopting the condition-based maintenance approach. The aforementioned 80/20 condition-based maintenance approach could provide as a reference to maintenance. From the findings, it is identified that the BI tool can not only visualize the data for display but also survey and assay a variety of power system failure data effectively. This study also found that most circuit breaker contacts had survived as their utility period expired, which is the ground for associated industries to adopt more adequate maintenance approaches to sustain the power supply quality with low-cost maintenance in terms of the circuit breaker internal inspection maintenance approaches.
