摘　　要：本文介绍了结合当地实际选取开发区某中小型机械厂工厂供配电系统,按照工厂投入使用实际情况以及实现相应功能之后工厂的计算负荷来确定该机械厂变电站主接线。通过设计相应接线方案,得出装设一台主变压器的接线方案在供电可靠性、安全性、供电质量、经济投资、耗电量等方面都比较优质,但是在灵活方便性和工厂扩建适应性上装设一台主变压器的接线方案稍差一些。This article introduces the selection of the power supply and distribution system of a small and medium-sized machinery factory in the development zone based on local conditions.The main wiring of the substation of the machinery factory is determined according to the actual situation of the factory and the calculated load of the factory after the corresponding functions are implemented.Through the design of the corresponding connection scheme,it is concluded that the connection scheme of installing a main transformer is of high quality in power supply reliability,safety,power supply quality,economic investment and power consumption,but the connection scheme of installing a main transformer is slightly worse in terms of flexibility,convenience and adaptability of factory expansion.
