| 摘 要： | 介绍了北京市部分地下、半地下变电所10 kV交联聚乙烯绝缘1 600 mm2单芯所内同相两根并联电缆的敷设、运行情况。通过计算分析出其载流量不平衡的主要原因是同相两根并联电缆的外感值不等。建议在同相两根并联10 kV大截面电缆线路中采用上下两层水平布置和三角形排列布置的敷设方式。

| Abstract: | The laying modes and running situation of two parallel 10 kV XLPE single-core cables with the same phase at some underground and half-underground substations of Beiiing are presented. The reasons causing the current carrying capability imbalance of two same phases parallel cables are analyzed and calculated. The laying mode that the symmetrical disposition for the two parallel 10 kV large section cable lines with the same phase is adopted on the upper and lower layers is suggested, it can be used as a reference. |
