摘　　要：本文介绍了超声波技术应用于电力设备绝缘状态检测的概况,其原理是当电力设备绝缘存在缺陷时,该部位电晕放电明显增强,通过对电晕放电的检测,可判断电力设备的绝缘是否存在缺陷。超声波检测可以在远离电力设备的地方进行,既安全又方便,超声波检测技术将成为电力设备状态检测的新方向。This paper introduced the general condition of the application of ultrasonic technology in testing electric power equipment insulation stage. The principle is when there is defect in the electric power equipmeat insulation, the corona discharge is clearly increased. Through the test of corona discharge, the insulation defect in electric power equipment can be found. The test of ultrasonic can be performed in the place far away from the electric equipment. Because of the characters of safety and convenience, it can be widely used for testing electric power equipments.
