摘 要

要提高高层建筑配电系统的可靠性，要正确选择各类配电设备的容量，就必须科学、合理的进行负荷计算。本文对符合计算中的相关问题进行了分析和探讨，就重要设备的容量选择做了较为详细的论述，提出了一些进一步提高配电系统可靠性的措施，并结合工程实例进行负荷计算，计算结果证明本文所述方法是正确合理，可在实际中应用。高层建筑比一般建筑遭受雷击的概率要大得多，而一旦遭受雷击，损失将非常严重。另外，普通建筑物防雷系统不但不能保护高层建筑物内的电子设备与计算机系统，反而可能会引入雷电。因此，高层建筑的防雷保护就越显重要，相应地对防雷保护提出了更高的要求。本文对于高层建筑物的防雷保护措施做了较为仔细的分析。

本设计主要包括强电部分设计、弱电部分设计及安防部分设计。即完成对小区的综合布线系统、照明系统、供配电系统、消防报警系统以及防雷接地系统的设计。设计的侧重点是该居民楼电气系统中供配电系统设计和照明系统设计，其中供配电系统主要包括负荷等级、负荷计算、变压器选择、互感器的选择、电缆的选择等。照明系统主要包括照明系统简介、照度方式种类、照度计算、电气照明设计等。

关键词：配电系统，照明，防雷接地

Abstract

To improve the reliability of the distribution system of high-rise buildings To correct choice of the capacity of various types of distribution equipmentMust be scientific, reasonable load calculation Right to comply with the issues related to the calculation of the analysis and discussion, a more detailed discussion on the capacity of choice for critical equipment, and made a number of measures to further improve distribution system reliability, and load calculation, with an engineering example calculationsto prove that the approach described here is correct and reasonable, can be applied in practice High-rise buildings the probability of being subjected to lightning is much greater than the average building, and once being struck by lightning, the loss will be very serious In addition, ordinary building lightning protection system will not only fail to protect the electronic equipment and computer systems in the high-rise buildings, but may introduce lightning. Therefore, the high-rise buildings Lightning protection of the more significant and important, and accordingly put forward higher requirements for lightning protection. Lightning protection measures for high-rise buildings, a more careful analysis.

In this essay there are mainly focusing on the design of forceful electric power design of security automation system and light current. Complete cell integrated wiring system lighting system ,power supply and distribution system fire alarm systems and lightning protection and grounding system design The design focus is the residential building electrical systems for power distribution system design and lighting system design supply and distribution system including load level, load calculations transformer selection choice of transformer cable choice the lighting system consists mainly of the introduction of lighting systems illumination mode types illumination calculations electrical and lighting design

Keywords: Distribution system Illumination Lighting protection and grounding
