1、小区配电所一次设计及 CAD 画图 -I- 摘要 小区配电是电力系统重要的一部分，小区配电系统的可靠性及安全性是维持 居民正常生活的基本前提，配电系统一旦出现问题， 会直接扰乱居民的生活规律， 影响生活生产，甚至会危及社会的稳定。小区配电系统是本文的主要设计内容， 本文从保障小区居民供电的可靠性、安全性以及经济性角度设计小区配电系统， 并考虑了随着社会经济的发展，居民负荷增长的可能，保证了 510 年满足居民 生活对电能的需求。本论文根据小区的实际负荷在正常运行下的工作电流选择了 变压器、断路器、隔离开关和互感器等电气设备，并根据其短路情况校验了所选 的电气设备的动稳定性与热稳定性、绘制了小区

2、的主接线图。由于小区的面积较 大，设计由小区的实际地理位置和负荷平衡的角度选择了变压器的建造位置，并 绘制了电缆沟的布置和截面图。 关键词 小区配电,设备选择,短路电流,设备校验 XX 学院毕业设计（论文） -II- Abstract As an important part of the electrical power system, the reliability and the security of the plot power distribution are the basic premise to maintain the inhabitant normal life, Onc

3、e the electrical power distribution system has the problem, it can harass inhabitant life directly, affects the life production, even can endanger the stability of the society. The plot power distribution system is the main content designed in this article, this article designs the plot power distri

4、bution system to supply power to inhabitants from safeguarding the reliability, the security and the efficiency angles, and has considered the possibility which the inhabitant power load grows with the social economy development, it guarantees satisfying the electrical energy demands of inhabitants

5、in 510 years. The article chooses electrical equipments such as the transformer, circuit breaker, isolator and mutual inductor according to the actual load of the plot under the normal operating current and verifies dynamic stability and the thermo stability of the electrical equipments which have b

6、een elected, this article also has drawn up the plot main wiring diagram. Because the plot area is big, the design has chosen the transformer construction position by the plot actual geographical position and the load balanced angle, and has drawn up the cable trench arrangement and the profile chart.
