摘要
单芯柔性电缆线路不停电作业方法是配网设备运维检修的一项重要内容,但由于电缆屏蔽层感应电压与电流的存在,给带电作业人员带来了一定的安全隐患。因此,本文从电缆的结构与作用以及旁路作业的基本原理出发,对单芯柔性电缆屏蔽层感应电压和电流进行了分析,提出了限制电缆屏蔽层感应电压及电流方法,提高了旁路系统的人身和设备安全、效率以及检修作业的便利性。
The single-core flexible cable line operation method without power failure is a common operation for distribution network maintenance.But the existence of induced voltage and current in the cable shielding layer,it will bring certain safety hazards to the operators.Therefore,starting from the structure and function of the cable and the basic principle of bypass operation,this paper analyzes the generation of induced voltage and current in the shielding layer of the cable,and proposes a method to limit the induced voltage and current in the shielding layer of the cable.In addition,the safety and efficiency of personnel and equipment of the bypass system and the convenience of maintenance work are improved.
