摘要
文中对境外住宅项目的电气设计进行了简要描述,通过现场调研,了解到当地电气设计的诸多要求和习惯,并在文中介绍了设计过程中针对外方要求和习惯做出的针对性调整。由于TT配电系统在我国建筑电气设计中并不常用,文中对TT配电系统与TN配电系统的区别做了简要描述,并通过ETAP软件进行系统仿真模拟计算,验证了保护电器对间接接触防护的灵敏度。最后对于规范的执行程度给出了建议,供同行参考。
The paper gives a brief description of the electrical engineering design of residential projects overseas. Based on knowledge of local people's requirements and habits regarding electrical design obtained through onsite investigation, the paper presents what adjustments are made to meet the requirements of the locals during the design process. As the TT power distribution system is not commonly used in the electrical design of architecture,the paper briefly discusses the differences between the TT power distribution system and the TN power distribution system and conducts system simulation with ETAP software to test the sensibility of the protection equipment to indirect contact protection. Finally the paper provides suggestions as to what extent should the specifications be implemented,as references for the professional community.
