　 隨著電力系統的不斷發展，變壓器等電力設備的運行可靠性愈加受到重視。絕緣油作為變壓器內部的主要絕緣和冷卻介質，其品質的劣化會直接影響變壓器的正常運行，甚至引發嚴重的設備故障。因此，對絕緣油品質的即時檢測和預警成為保障電力系統安全運行的重要課題。傳統的絕緣油品質檢測方法主要依賴於色譜分析及油品檢測等技術，這些方法存在耗時耗成本及檢測周期長等問題，無法實現即時檢知。光纖光柵感測技術因其特有的優勢，為絕緣油品質劣化的即時檢測提供了一種新穎技術且有效的解決方案。光纖光柵具有體積小、高靈敏度、抗電磁干擾能力等優點。光纖布拉格光柵（FBG）作為光纖光柵技術的一種典型應用，能夠通過光譜響應特性的變化來檢測溫度等參數，並且適用於多點、多參數的分佈式測量。本論文研究光纖光柵感測技術在絕緣油品質劣化檢測中的應用，為電力設備的運行狀態和預防性維護提供了一種高效率且可靠的新途徑，具有廣泛的應用前景。未來的研究將可進一步優化傳感器佈置和數據處理算法，提升系統的整體性能，推動其在電力行業的實際應用。

　　With the continuous development of the power system, the operational reliability of electrical equipment such as transformers is increasingly emphasized. Insulating oil, serving as the primary insulation and cooling medium within transformers, directly affects their normal operation when its quality deteriorates, potentially leading to serious equipment failures. Therefore, real-time detection and early warning of insulating oil quality have become critical issues for ensuring the safe operation of power systems. Traditional methods for assessing insulating oil quality primarily rely on chromatographic analysis and oil testing, which suffer from drawbacks such as time consumption, high costs, and long detection cycles, making real-time detection impractical. Due to its unique advantages, fiber optic grating sensing technology provides a novel and effective solution for real-time detection of insulating oil degradation. Fiber optic gratings are characterized by their small size, high sensitivity, and immunity to electromagnetic interference. Fiber Bragg grating (FBG), as a typical application of fiber optic grating technology, detects parameters such as temperature through changes in spectral response characteristics and is suitable for distributed measurement of multiple points and parameters.
　　This thesis explores the application of fiber optic grating sensing technology in detecting insulating oil degradation, providing an efficient and reliable new approach for monitoring the operational status and preventive maintenance of electrical equipment, with broad prospects for application. Future research will focus on further optimizing sensor deployment and data processing algorithms to enhance system performance overall, thereby advancing its practical application in the power industry.
