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

主变压器是光伏电站最重要的设备之一，不仅承担着电能转换的核心任务，还是系统安全、稳定运行的重要保障，一旦发生故障，可能引起全站失电，甚至影响系统的稳定性[1]。（剩余2736字）
