摘　　要：为了提高高压开关柜运行的安全性,笔者在介绍超高频法局部放电在线监测系统的基础上,设计制作了4种典型放电模型,并应用此在线监测系统对高压开关柜进行了局部放电试验研究,获取了大量放电谱图和放电脉冲波形,并对放电的相位特征进行了分析。结果表明:该系统具有抗干扰能力强、工作稳定性好等优点,满足高压开关柜局部放电在线监测的要求。An on-line partial discharge monitoring system based on UHF technique for high voltage switchboard is introduced, and four typical discharge models are designed. Then the on-line partial discharge UHF monitoring system is used to conduct PD test on a high voltage seiehboard to obtain plenty of discharge patterns and pulse waves, and the phase characteristics of PD are analyzed. The experimental results indicate that the system has the advantages of better anti-interference capability and operating stability to meet the needs of on-line PD monitoring for high voltage switchboard.
