摘 要
本设主要阐述了现代化小区各系统电气设计的设计依据。首先应该对小区的负荷进行统计，在统计的时候应全面考虑，包括近几年来当地小区的一户平均用电水平，以及逐年的变化趋势。还与一些大城市的户平均用电水平进行了比较，以及已经建设好的小区的变压器的负荷情况来综合考虑每户应该规划的负荷，以免造成电能的浪费和投资的增多。确定好负荷之后，确定变压器的容量。要紧跟变压器的发展，采用性价比比较高的变压器。考虑到居民小区本身的特点，以及箱式变压器的蓬勃发展，宜把小区分成若干供电团组来供电，由总控制室来管理。其中总控制室配备无功补偿，并且安装一台或两台油式变压器来给附近的住宅楼供电。在变压器的选址方面，严格遵守电力安全规定，绝对不能影响居民日常生活。在主接线方面充分结合了小区的负荷分布情况和道路的走向，本着高效，节约的原则确定了方案。在电缆的选择和铺设方面，严格遵照《电力工程电缆敷设规范》等相关的国家行业标准来选择和铺设。进行了短路电流的计算，主要设备的选择和校验，及接地防雷的设计。

Including the electricity consumption of the local residential in recent years, and the trend of changes year by year. I also contrast with the electricity consumption of the developed city ,and the Situation of transformers that have constructed.
