介绍采用铝合金试块和瓷件对支柱瓷绝缘子及瓷套进行超声波探伤灵敏度的试验研究,经对测试数据的统计和分析,给出了不同探伤方法所适用的探伤灵敏度,分析了缺陷反射回波的基本特征,为支柱瓷绝缘子及瓷套的检测和制定《电网在役支柱瓷绝缘子及瓷套超声波检验技术导则》行业标准提供了关键技术依据。
This paper introduces the experimental research on the ultrasonic testing sensitivity of the porcelain insulators and porcelain sleeves with aluminum alloy test pieces and porcelain pieces. The test sensitivity and sensitivity of different test methods are given through the statistics and analysis of the test data. The basic characteristics of the wave provide the key technical basis for the inspection and development of the pillar porcelain insulators and porcelain sleeves and the development of the industry standard of the Technical Guidelines for the Ultrasonic Inspection of Porcelain Insulators and Porcelain Sets in Power Station in Service.
