摘要

分析超声波局放仪的工作原理和特性指标。提出一种声发射信号模拟测评法,详细分析了超声波局放仪高级功能测评主谐振频率、灵敏度、线性度和方向性4个性能指标。通过对超声波局放仪现场测评对比,验证了笔者所提测评方法的有效性。
        The working principle and characteristic indexes of the ultrasonic partial discharge instrument were analyzed and an acoustic emission signal simulation and evaluation method was proposed,including the analysis in detail of four main performance indexes like the main resonance frequency,sensitivity,linearity and directivity of ultrasonic partial discharge instrument in the advanced functional evaluation. Comparing the ultrasonic partial discharge instrument on site verifies effectiveness of the evaluation method proposed.
