| 摘 要： | 设备在损坏之前均存在局部放电信号，对油中多层绝缘介质局部放电研究可预测设备的损坏过程，以便保障其安全运行．笔者对油中多层绝缘纸在固定外加电压状态下放电发展规律进行研究，发现这种绝缘结构的放电幅值、频率随时间交替变化，最后发展到击穿．

| Abstract: | There is partial discharge signal before a machine is damaged. The process of the machine damaging can be predicted by the study of the partial discharge process of insulated multilayer media in oil, so it is ensured that the machine runs in safety. In this paper, the partial discharge law of insulated mutilayer paper under a constant external voltage in oil is studied, and it is found that the amplitude and frequency of the discharge signal vary alternately with time before breakdown. |
