Research on Fault Mechanism and Detection Technology of Buffer Layer in High Voltage XLPE Cables
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.
