摘要

由於歷年來，曾經發生多起變壓器事故，導致供電中斷並使鄰近變電設備損壞，因而造成停電或電壓驟降，產生嚴重經濟損失。有鑑於此，本研究搜集並統計台電公司各級浸油式變壓器因各部元件之故障造成火災等重大事故，運用失誤模式與影響分析(FMEA)之方法，探討浸油式變壓器重要元件之失誤模式及其可能的影響，以提供國內變壓器製造廠商及使用者在設計、製造、安裝及運轉維護時，可以應用本質較安全設計之策略，如強化、取代、減弱、限制影響、避免骨牌效應、防愚設計、狀態清晰、易於控制、軟體等，來消除或控制變壓器潛在的危害因子。

Over the years, transformer accidents have caused power failures and damaged switchyard equipment, resulting in the loss of electrical power and voltage drops and consequently serious disruptions in productivity. In light of this, data from the Taiwan Power Company was analyzed in order to determine the potential for oil immersed transformers to have accidents that could result in fires. Failure mode and effect analysis was used to investigate the failure modes of important components and possible effects on the oil immersed transformer. This analysis was offered to domestic transformer manufacturers. The inherently safer design strategy for designing, manufacturing, installing, and operating transformers included safeguards, such as intensification, substitution, attenuation, limitation of effects, avoiding the knock-on effect, fail-safe design, making clear the status, ease of control, and software controls, to eliminate or minimize potential hazard factors.
