摘　　要：采用矿物绝缘油与牛皮绝缘纸作为试验材料,开展了不同时长的变压器油纸绝缘加速热老化试验,并在不同时刻进行换油操作,以研究换油对油纸绝缘热老化特性参数的影响。Using mineral insulation oil and kraft insulation paper as test materials, accelerated aging tests of transformer oil-paper insulation for different periods of time are carried out. The oil replacement operation is performed at different moment to study the influence of oil replacement on the thermal aging characteristic parameters of oil-paper insulation.
