摘要
介绍了一起从自备发电机组至供电系统低压母线的联络电缆受集肤效应等因素影响而发生短路事故的基本情况,并在分析的基础上采用三相单心电缆品字并联分组敷设的方法来处理的成功案例。
The basic situation of a short-circuit accident of the contact cable from standby generating units to low-power busbar of power supply system is described in this paper. The cable suffered from the skin effect and was affected by other fac- tors. Based on the analysis, a method of three-phase and one-core cable parallel in symmetry laying for the problem is put for- ward. The success application case of bridge line is introducedin this paper.
