摘　　要：近年来修山水电站1#主变压器在夏季丰水期高负荷运行时油面温度高,为确保主变压器安全运行,调整机组出力或转移负荷以降低变压器运行温度。通过分析1#主变压器夏季丰水期高负荷时温升过高原因,提出有效解决措施,提升1#主变压器所带负荷能力和发电经济效益,并延长了变压器使用寿命,取得良好的效果。In recent years,the oil surface temperature of No.1 main transformer in Xiushan Hydropower Station is high during high load operation in summer.In order to ensure the safe operation of the main transformer,it is necessary to adjust the unit output or transfer the load to reduce the operating temperature of the transformer.Based on the analysis of the causes of the temperature rise of No.1 main transformer during the high load period in summer,the effective measures are put forward and good results are obtained.It not only improves the load carrying capacity and economic benefit of power generation of No.1 main transformer,but also prolongs the service life of transformer.
