有鑑於目前台電供電系統斷路器種類及數量繁多，且約有1/6斷路器已超過廠家建議使用年限，目前建議年限為20年，依據浴盆曲線之設備劣化趨勢可知，上述設備已處高風險運轉狀態，目前台電公司僅參考IEC62271-100國際規範，針對斷路器同步動作延遲時間進行定義，尚未建立長期追蹤評估規則，有鑑於此，急需建置斷路器狀態預防評估機制，針對斷路器異常狀態達成早期預防及處置，以確保電網運轉安全及可靠。
本研究係運用大數據分析方法，對既有斷路器點檢紀錄資料庫20餘萬筆啟斷時間進行研究，期能透過大數據資料分類及標準化過程，進一步發現系統斷路器潛在弱點，並提供維護人員即時維護資訊，並透過不停電之安全可靠方式，延長設備生命週期。文中運用大數據分析之常態分佈及信賴區間等分析方法，獲得各電壓等級動作時間標準差，此標準差可做為斷路器健康狀態初步評估依據，達成設備劣化趨勢早期診斷目標。
最後本文藉由R語言程式建立人機介面互動平台，可將設備弱點及劣化趨勢診斷成果，提供給現場人員進行維護規劃，並適時調整及安排設備維護點檢時間。最後本文藉由實例驗證本研究方法之可行性，可確實達成降低運轉風險及維護成本之目標。

Based on many kinds and counts of Circuit Breaker (CB) in Taipower system and one-sixth of CBs are over utility limited of manufacture suggestion that the work is twenty years. According to Bathtub Curve, these equipment is working in high risk status. The operation time was focused on the Taipower CB maintenance that is refer to the IEC62271-100 and the CB estimate is not built in long term maintenance schedule. In order to improve operation safety and reliability, the mechanism of CB estimate has to be built in the prevention and detection of the CB operation quality early.
The operation time of CB that is over two hundred thousand sets of maintenance record that was studied in this research using the Big-data analysis. The CB hidden weakness can be discovered by the operation trend from big-data analysis. The normal distribution and reliability area analysis were designed in this study. The time standard error for each voltage level can be used in CB healthy status estimate in initial stage and the equipment weakness trend can be obtained from the analytical result.
Finally, the User-Interface platform can be built by using the R language. The analytical result of the equipment weakness trend can be obtained for staff maintenance planning or rescheduling. The experimental cases are verified by this method and can reach the goal of reducing operation risk and maintenance cost.
