摘要

通过分析针状空隙PMMA绝缘的局部放电和放电发光，进行了针状空隙PMMA绝缘劣化诊断实验。结果表明，通过对放电发光的图像分析，可以精确地观察到放电的状态。在退化的早期和中期，发生了蜂群脉冲微放电。树发生后，放电幅度和脉冲数迅速增加，且放电发光与最大放电幅度的相关性显著。

Relationships between partial discharge magnitude and discharge luminescence of insulation

An experiment was carried out to diagnose the deterioration of PMMA insulation with a needle void by analyzing partial discharge and the discharge luminescence. It was shown that, by using image analysis of the discharge luminescence, the state of the discharge could be minutely observed. At the early and the intermediate stages of the deterioration, a swarming pulsed microdischarge occurred. After the occurrence of the tree, the discharge magnitude and the number of pulses are rapidly increased, and the correlation of the discharge luminescence and the maximum discharge magnitude is marked.<>
