设计共分为绪论、变电所电气部分设计、变电所二次回路电源设计介绍及保护规划、结论四大部分，同时附带部分设计图纸。本论文由无忧论文网www.51lunwen.org整理提供本次设计中选取两台变压器，主接线设计要灵活简单、操作方便。一次侧才用单母线分段模式；二次侧由于馈电线路较多，负荷较为重要，因此也采用单母线分段模式。文中进行了短路电流计算，主要设备选择及校验（包括断路器、隔离开关、电流互感器、母线等），并同时附带介绍了所用电和直流系统、继电保护、防雷保护、接地保护和照明及消防规划。在专题设计中，设计二次回路操作电源和中央信号装置。经过功能组合和优化设计，为变电所提供监控支持。他的运用可实现变电所高水平的管理。
本文根据工厂供电设计的原则，以小型化为模式基础，主接线设计灵活、简单方便。设备选择中采用检修周期长、可靠性更高的设备。本论文由无忧论文网www.51lunwen.org整理提供设计不片面追求高指标、高档次，而是安全、维护方便、技术先进及经济合理。
此外，根据厂内负荷情况，合理制订布局方案和选用设备。
Abstract:The design of metallurgical enterprises against the factory power supply design requirements. As the author of the substation design, a design for example, a similar substation at home and abroad on the status and conditions. Substation on the design patterns were studied.
Design consists of introduction, the design of electrical substations, power substations secondary circuit design presentation and preservation plan, Conclusion four most, incidental part of the design drawings. The design chosen two transformers, main wiring design should be flexible and simple, 本论文由无忧论文网www.51lunwen.org整理提供convenient operation. Only one side of the single-mode bus subparagraph; As the secondary side Feeders more, the load is more important. therefore, the single-bus segmented model. The text of short-circuit current, major equipment selection and check (including circuit breakers, isolation switches, CT, Bus), and at the same time on the fringe as electricity and DC system, relay protection, lightning protection, earthing and lighting protection and fire planning. The thematic design, the design of the secondary circuit to operate the Central Power and signal devices. After the composition and function of optimal design for the provision of substation monitoring support. He may use the substation to achieve a high level of management.
Based on the factory power supply design principles, as a small model based on the main wiring design flexibility, simplicity and convenience. Equipment used long maintenance cycle, and higher reliability of the equipment. Design is not one-sided pursuit of high standards, high quality, but safety and convenience,
