摘 要： 通過對變壓器油定期化驗分析，提前發現變壓器內部故障，判斷故障原因并及時處理故障, 避免了一次重大設備損壞事故。油色譜分析作為變壓器故障分析的一種手段非常有效，但還應綜合考慮其他試驗結果及現場具體情況。在變壓器的運行維護中，應定期對其附屬設備進行檢查，避免設備超期服役造成的故障。1# 主變大修后各項指標沒有明顯增長，保證了變壓器的安全穩定運行。
關鍵詞： 變壓器油；油色譜分析；烴超標

Abstract: Periodical assay and analysis of transformer oil made interior fault of transformers detected in advance, fault causes judged and fault processed in time, which avoided a great damage to equipment. Oil chromatographic analysis was a kind of good way of transformers fault analysis, but the other testing result and onsite conditions should still be considered comprehensively. During the maintenance of transformers operation, periodical inspections were carried out for the transformers accessory equipment to avoid fault due to extended activity duty of equipment. After the number one main transformer was overhauled, each index of the transformer had no obvious increase, which ensures safe and stable operation of the transformer.
Key words: transformer oil; oil chromatographic analysis; hydrocarbon overweight
