摘　　要：本文中笔者以云广±800kV直流输电工程楚雄换流站特高压换流变现场局部放电试验为例,详细研究了特高压换流变局部放电试验过程中的干扰源,如空间电磁波、电晕、脉冲型干扰和检测阻抗带来的干扰及所采取的抗干扰措施。The UHV converter transformer on-site partial discharge test of Yun-Guang ±800kV DC transmission project of Chuxiong Converter Station is mentioned as an example.The interference sources in the UHV converter transformer partial discharge test are researched.The interference and anti-interference measures which are caused by the elements such as the space electromagnetic wave,corona,pulse interference and the detection impedance are presented in this paper.
