用于变压器局部放电源定位测量的高灵敏度超声波传感器的研究

A Study of High Sensitivity Supersonic Transducer Applied in the Measurement of PD Location in Transformer

本文论述了一种抗干扰能力强和灵敏度高的超声波传感器及其选择压电晶体的方法。

This paper describes a kind supersonic transducer with high sensitivity and strong property of suppressing interference,and the method of selecting piezoelectric crystal.Through simulation experiments,the relationship between supersonic response and apparent charge quantity and the effects of several elements were obtained.
