摘　　要：本文以真型开关柜为基础研制了开关柜带电检测试验平台,首先利用该平台成功模拟悬浮电位放电缺陷,采用超声波检测法(AE)与脉冲电流法(PC)的比对找出悬浮电位放电的规律,包括典型图谱,超声波信号幅值与局放量关系,验证了该平台的有效性,最后针对该平台提出了后续研究方向。In the paper the experiment platform is developed, and the suspended discharge fault is simulated in this platform. The regular of suspended discharge is discovered through the comparison between ultrasonic wave and pulse cur rent , which includes typical map, the relationship between acoustic emission （ AE） method and pulse current （ PC） method. The effectiveness of the platform is proved and the subsequent research directions are put forward.
