摘　　要：为规范超声波局部放电检测仪的技术要求,统一技术标准,促进超声波局部放电检测技术的应用,提高电网的运行可靠性,研究超声波局部放电检测仪的校验技术十分必要。文章介绍了超声波局部放电检测仪的技术原理和要求,提出了超声波局部放电检测仪的校验方法,建立了相应的校验系统,探讨了超声波局部放电检测仪的现场校验方法。所述的校验方法具有稳定性高,重复性好的特点,弥补了超声波局部放电检测仪缺乏校验方法和手段的问题,有一定的参考价值。It is necessary to research on the calibration technology of ultrasonic partial discharge detector in order to standardize its technical requirement,unify its technical standard,promote the application of ultrasonic test technolo-gy,and improve the reliability of the power grid. The technical principle and requirement of ultrasonic partial dis-charge detector has been introduced, and a calibration method for such detector has been presented in this paper. Moreover,the calibration system has been established,and the field test technology has been discussed in de-tail. This calibration method has high stability and repeatability which will provide useful means to calibrate ultrasonic partial discharge detector.
