Abstract： A tripping event occurred in a photovoltaic power station for heavy gas protection of the main transformer. Through fault recorder analysis， main transformer inspection and testing， it was determined that this event was a misoperation of heavy gas protection caused by the stuck metal bellows of the oil conservator. event The incident handling process and the root cause of the incident are analyzed in detail， and preventive measures are proposed to avoid the recurrence of similar incidents.

Keywords： transformer; corrugated metal oil conservator; heavy gas protection; precautionary measures; photovoltaic power station

主變壓器是光伏電站最重要的設(shè)備之一，不僅承擔(dān)著電能轉(zhuǎn)換的核心任務(wù)，還是系統(tǒng)安全、穩(wěn)定運(yùn)行的重要保障，一旦發(fā)生故障，可能引起全站失電，甚至影響系統(tǒng)的穩(wěn)定性[1]。（剩余2736字）
