摘要
本文从线路过负荷保护的作用及意义出发,结合IEC标准及国家相关规范,针对消防负荷的供电回路(或叫末端回路)及配电干线的过负荷保护做法展开讨论,力求找到一种既满足规范要求又能使整个供配电系统及所服务场所安全的线路过负荷保护策略。
Based on the function and significance of line overload protection, combined with IEC standards and relevant national norms,this paper discusses the overload protection methods of power supply circuit( or terminal circuit) and distribution trunk line for fire load,and strives to find a line overload protection strategy which can not only meets the specification requirements but also makes the whole power supply and distribution system and the service place safe.
