摘要

文中针对电力电缆局部放电检测中柔性超声传感器灵敏度的标定方法展开研究。传统标定平台因声阻抗与电缆不匹配，导致所标定出的柔性传感器灵敏度不能准确反映其在电缆局部放电检测中的实际情况。文中通过构建基于聚乙烯板的新型灵敏度标定平台，由于聚乙烯板的声阻抗特性与电缆材料高度相似，解决了传统钢板平台的标定偏差问题。文中分析了柔性薄膜传感器在钢板标定平台和聚乙烯板标定平台上的灵敏度标定结果，发现在钢板平台上标定的柔性传感器峰值灵敏度仅为53 dB，而在聚乙烯板平台上标定的灵敏度提升至66 dB。在电缆上开展的传感器灵敏度验证性实验表明，聚乙烯板平台上标定出的灵敏度能比较准确的反映柔性传感器对电缆上传播的微弱超声信号的检测能力。文中所建立的新型标定平台，可为柔性超声传感器灵敏度的标定建立提供依据和参考。

Abstract

This paper focuses on the calibration method for the sensitivity of flexible ultrasonic sensors for partial discharge detection of power cables. The traditional calibration platform

due to the mismatch between the acoustic impedance and the cables

causes the sensitivity of the calibrated flexible sensor not to accurately reflect its actual situation in the partial discharge detection of cables. In this paper

by constructing a new type of sensitivity calibration platform based on polyethylene plates

the calibration deviation problem of traditional steel plate platforms is solved thanks to the high similarity of the acoustic impedance characteristics of polyethylene plates to those of cable materials. The sensitivity calibration results of the flexible film sensor on the steel plate calibration platform and the polyethylene plate calibration platform are analyzed

finding that the peak sensitivity of the flexible sensor calibrated on the steel plate platform is only 53 dB

while the sensitivity calibrated on the polyethylene plate platform is increased up to 66 dB. The verification experiment of sensor sensitivity performed on the cables shows that the sensitivity calibrated on the polyethylene plate platform can accurately reflect the detection ability of the flexible sensor for the weak ultrasonic signal propagating on the cables. The new calibration platform set up in this paper can provide a basis and reference for the calibration of the sensitivity of flexible ultrasonic sensors.
