摘要
本文中作者以矿用干式变压器Nomex绝缘纸为研究对象,制作了放电模型,进行了局部放电试验,利用高频电流传感器采集不同湿度下的放电信号,得到放电发展过程中的PRPD谱图及放电特征量。
Taking the non-aging Nomex insulation paper of mining dry transformer as the object,the model of rod-plate electrode discharging along the surface is made. The PD tests are carried out in this paper by the authors. High frequency current sensors are used to collect discharge signals at different humidity, and PRDP spectra and discharge characteristics are obtained during the development of discharge.
