摘要
该文从一根运行22年的10 kV XLPE电缆,截取两段不同敷设条件的样品,通过测量电缆绝缘电阻、介质损耗,开展局部放电、工频耐压、逐级耐压等电气性能试验,以及机械性能试验,分析了敷设运行环境对电缆性能的影响。
In this paper,two sections of samples with different laying conditions are intercepted from a 10 kV XLPE cable that has been running for 22 years.By measuring the cable insulation resistance and dielectric loss,and carrying out electrical performance tests such as partial discharge,power frequency withstand voltage and step-by-step withstand voltage,as well as mechanical performance tests,the influence of laying and operation environment on cable performance is analyzed.
