摘要
高压XLPE电缆缓冲层故障频发,严重影响电缆安全运行,引起了广泛关注。根据缓冲层烧蚀故障特征,分析了高压XLPE电缆缓冲层电场特性并进行了初步仿真研究,得出局部放电是导致缓冲层故障的直接原因。提出了几种理论上可行的缓冲层故障检测方法并进行了简单验证,其有效性还待后续进一步试验与研究。
The frequent occurrence of faults in the buffer layer of high voltage XLPE cables significantly affects their safe operation,attracting widespread attention.Based on the characteristics of buffer layer erosion faults,this study conducts an analysis of the electric field distribution in the buffer layer of high voltage XLPE cables and performs preliminary simulation studies.It is determined that partial discharge is the direct cause of buffer layer faults.Several theoretically feasible detection methods for buffer layer faults are proposed and subjected to initial validation,although their effectiveness requires further testing and research.
