摘要
对单芯电缆交叉互联金属护套感应电流进行了研究。为了控制实际电缆线路工程中单芯电缆的护套感应电流,建立了复杂通道条件下,计算单芯电缆护套感应电流的数学模型,提出了通过调整电缆排列来预控感应电流的方法,并编制了相应程序,以实现护套感应电流的计算和预控。全文共分两大部分:第一部分为感应电流的计算和预控;第二部分为计算程序编制和应用。
The induced current in the cross-bonded metallic sheath of single core cables was investigated.In order to control the induced current in the metallic sheath of single core cables in actual cable lines,a mathematical model to calculate the induced current under the conditions of complicated cable tunnels was established.A method to pre-con-trol the induced current by modification of cable arrangement was presented.The corresponding programme was com-piled in order to calculate and pre-control the induced current in the metallic sheath.This paper consists of two parts.Part 1 deals with calculation and pre-control of the induced current.Part 2 deals with compilation and application of the calculation programme.
