摘要
从现行国家标准《建筑物电气装置》GB 16895.3-2004以及IEC 60364-5-54:2002对保护导体的定义入手,介绍了保护导体截面积的计算方法,从工程设计的角度,探讨如何通过热稳定校验公式,在低压配电系统设计中经济合理地选择电缆的保护导体的截面。
From the current national standard GB 16895.3-2004 ＂Electrical Installations of Building＂ and the definition of the protective conductor in IEC 60364-5-54：2002, this paper introduces the calculation method of sectional area of the protective conductor. From the view of engineering design, this paper discusses how to select the section of the protective conductor for cables in economical and reasonable ways in the design of low voltage distribution system through the thermal stability verification formula.
