高层住宅楼供配电系统的设计

摘要

我国的城市建设过程中，住宅向着高层化趋势发展。高层住宅楼，因其为住户提供的安全、舒适、高效、节能的居住环境，受到了越来越多人的青睐，也成为现代人主要的居住方式。与此同时，高质量的高层住宅楼供配电系统的设计就显得尤为重要。在电气设计时既要考虑用电负荷日益增长的需要，又要满足供电的可靠性及安全性的要求。

本课题以高层建筑的供配电系统为研究对象。为了达到用户能够安全、可靠、高效用电的目的，我们对高层建筑的供配电系统整体进行设计。其中包括对建筑负荷的计算，选择恰当地供电方式；进行短路电流的计算，选择合适的导线及低压电器产品；对室内照明进行设计；对防雷接地的设计等。同时为了提高设计质量及缩短设计周期，本课题采用功能强大的建筑电气软件CAD来设计供配电系统的电路图。

The Design of High-rise Residential Building Power

Supply and Distribution System

ABSTRACT

In the process of urban construction in our country, the housing development trend towards upwards. High-rise residential buildings, because of its for residents to provide safe, comfortable, efficient and energy saving living environment, got the favour of more and more people, modern has become the main way of living. At the same time, the high quality of high-rise residential building design of power supply and distribution system is particularly important. In the electrical design should not only consider the increasing needs of the power load, and to meet the requirements of the reliability and security of the power supply.

This topic in power supply system of high-rise building as the research object. In order to achieve the user to the purpose of safe, reliable and efficient utilization, our power supply system of high-rise building the overall design. Including the building load calculation, choose proper power supply way; For the calculation of short-circuit current, select the appropriate conductor and low-voltage electrical products; For indoor lighting design; The design of lightning protection grounding, etc. At the same time in order to improve the design quality and shorten the design cycle, this subject adopts powerful building electrical software AutoCAD to design the circuit diagram of power supply and distribution system.

Key Words:Electrical Design ；security；Load calculation；Lightning protection and grounding；Software AutoCAD
