非接触式超声波局放检测仪校验平台研究

Research on calibration platform for non-contact ultrasonic partial discharge detector

非接触式超声波局放检测仪缺乏统一的性能校验平台,影响电力设备局放检测结果的有效性和可靠性,在现有接触式超声波检测平台校验基础上,建立了相应的非接触式超声波局放检测装置校验平台,并提出了模拟装置,实验室环境联合校验方法。所述的校验方法具有稳定性高,重复性好的特点,弥补了非接触式超声波局部放电检测仪在空间,实用性与理想环境差异等问题,有一定的参考价值。

The lack of a unified performance calibration platform for the non-contact ultrasonic display detector affects the effectiveness and reliability of the test results of the power equipment display.Based on the verification of the existing contact ultrasonic test platform,a corresponding non-contact ultrasonic display test device calibration platform has been established.The simulation device and laboratory environment test method are proposed.The calibration method has the characteristics of high stability and good repeatability,which makes up for the difference between non-contact ultrasonic partial discharge detector in space,practicality and ideal environment,and has certain reference value.
