摘要 随着超声检测技术在变压器局部放电检测系统中的广泛应用,如何选择一个适合应用的超声传感器成为一个亟待解决的问题。通过对目前国内外变压器局部放电检测系统中超声传感器的应用现状及适用条件,以及各种传感器的灵敏度及工作频带等的实验和对比分析,指出了各种超声传感器的应用特点并预测了变压器局部放电检测系统中超声传感器的发展方向。 With the widely use of ultrasonic detection technology in the transformer partial discharge detection system, how to choose a suitable ultrasonic sensor is becoming very important. Through comparing and analyzing the sensitivity and working frequency-band of various ultrasonic sensors, the application and applied condition in transformer partial discharge detection system at home and abroad, the characteristics of the mentioned ultrasonic sensors are pointed out, and then the development direction of the ultrasonic sensors in transformer partial discharge detection system is predicted.
