摘　　要：为保障电缆投运后的安全性和可靠性,对220 kV长距离大截面交联聚乙烯电力电缆进行串联谐振试验和串并联谐振试验对比分析;同时,对长度为14.45 km的220 kV电力电缆进行容升现象仿真分析。现场试验结果表明,220 kV长距离大截面交联聚乙烯电力电缆的现场交接耐压试验适宜采用串并联谐振试验方案,各试验设备的温升可控且在允许范围内,能够满足220 kV长距离电力电缆的耐压试验要求。To ensure safety and reliability of power cables after putting into operation,series resonance test scheme and series parallel resonance test of 220 kV long-distance large-cross-section XLPE power cable were compared.And the capacity rise phenomenon of 220 kV power cable with a length of 14.45 km was simulated.Results showed that for on-site Acceptance voltage test of 220 kV long-distance large-cross-section XLPE power cable,series parallel resonance test was suitable,and the temperature rise of each test equipment was controllable and within the allowable range,which could meet the voltage test requirements of 220 kV long-distance power cable.
