| 摘 要： | 电力电缆线路改造时交叉互联后容易造成换位的三段电缆不等长,从而引起护层感应电压不平衡。本文通过对电缆护层感应电压的理论分析,提出了在末端电缆护层上连接电感元件进行电压补偿的方法,可有效地减小由于护层感应电压不平衡所造成的影响。

| Abstract: | During the renovation of power cable lines,the cross interconnection usually give rise to three sections of transposed cables with different lengths,which will cause unbalanced induced sheath voltage.By theoretical analysis of the induced sheath voltage,this paper suggests a method to make voltage compensation,in which an inductance element is connected to the sheath end and thus reduces the effect caused by the unbalanced induced sheath voltage. |
