摘 要： 通過對變壓器油定期化驗分析，提前發(fā)現(xiàn)變壓器內(nèi)部故障，判斷故障原因并及時處理故障, 避免了一次重大設(shè)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(yīng)綜合考慮其他試驗結(jié)果及現(xiàn)場具體情況。在變壓器的運行維護中，應(yīng)定期對其附屬設(shè)備進行檢查，避免設(shè)備超期服役造成的故障。1# 主變大修后各項指標(biāo)沒有明顯增長，保證了變壓器的安全穩(wěn)定運行。

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
