摘 要：提出了一種不受變壓器運行條件約束的繞組在線診斷方法。在線采集實際運行中的變壓器振動數(shù)據(jù)，分析振動數(shù)據(jù)并獲取變壓器振動曲線，振動曲線結(jié)合繞組理論模型，最終獲得變壓器繞組運行狀態(tài)。該方法與被測變壓器沒有電氣連接，對設(shè)備的正常運行無任何影響，可以安全、可靠地達到診斷目的。

Abstract: This paper proposed an online winding diagnosing method without the condition binding of transformer’s operation. The transformer winding condition would be finally obtained through combining vibration curve with winding theory model, and this curve could be got by analyzing vibration data which was collected online during the transformer’s real-time operation. There was no electrical connection between the tested transformer and the testing device, which has no impacts on the normal operation of this transformer. This method could diagnose the tested transformer safely and reliably.
Key words: transformer; clamping force; vibration signal analysis; online condition diagnosing
