摘要
《民用建筑电气设计规范》和《建筑物电子信息系统防雷技术规范》都规定:电子信息系统设备由TN系统供电时,其配电线路必须采用TN-S接地形式,而采用220/380V电源进线、规模较小的建筑物均无法满足规范的此条规定。对此问题进行了分析、探讨。
Both Code for Electrical Design of Civil Buildings and Technical Code for Protection against Lightning of Building Electronic Information System stipulate that the power distribution system of electronic information system equipments must adopt the TN-S eartbing type when it's power supply adopts TN system, but the articles cannot be met by small- scale buildings with 220/380V power input lines. The problem is analysed and discussed in this article.
