摘　　要：通过对110kV都北线电缆工程中电缆护套感应电压和护套链中环流的计算,确定电缆的接地方式。指出本工程中电缆交叉互联的单元分段即使在最大负荷电流情况下,护套的感应电压和护套链电路中的环流均满足设计规范要求。According to the calculation of induced voltage and circulating current in the jacket of 110kV Dubei XLPE cable to fix on grounding way, Basing on this case, in this article the author pointed out that induced voltage and circulating current in the jacket of cable cell-sections applied cross-bonding connection in this engineering still meet to the design standard requirements even under max load current.
