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, 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, advanced technology and the economy.
In addition, under the load of the plant, to formulate a reasonable layout program and select equipment.
