摘　　要：对受潮变压器油和油纸复合绝缘材料分别进行了变化低温环境下的工频击穿试验。结果表明,受潮的变压器油与油纸复合绝缘材料在降温过程中击穿电压与水分析出量有关。The power frequency breakdown characteristics of the moist transformer oil and oil-paper composite insulcation naterials are tested under lower temperature conditions. The results show that the breakdown voltages of the moist transformer oil and oil-paper composite materials are related to the water contents during temperature reduction.
