1、 2012 届本科毕业设计 小型工厂变配电所主接线的电气 CAD 设计 院 (系) 名 称 物理与电子信息学院 专 业 名 称 电气工程及自动化 学 生 姓 名 学 号 指 导 教 师 完 成 时 间 2012 年 5 月 13 号 1 小型工厂变配电所主接线的电气 CAD 设计 摘要:小型工厂变配电所,是将 610kV 降为一般用电设备所需低压 220V/380V 的终端变电所,它一般有装有一台或两台主变压器两种接线方案。主接线图也就 是主电路图,是表示系统中电能输送和分配的电路图。而用来控制、指示、测量 和保护电路(即一次电路)及其中设备运行的电路图,称为二次接线图或二次电 路图,也称为二
2、次回路图。工厂变配电所的主接线图要求安全、可靠、灵活、经 济, 相对比较严格。 本文根据计算得出负荷和容量, 确定要选一台或两台变压器, 最后用 CAD 画出小型工厂变配电所的主接线图。 关键词:主接线图;变电所;主变压器;电气 CAD Main Wiring Diagram For Electrical CAD Design Small Factories Substation Abstract: Small factories substation, will be reduced to general electrical equipment required for low volta
3、ge 220V/380V from 6 10kV terminal substation, and its main terminal programs are generally equipped with one or two main transformers. The main wiring diagram that is the main circuit schematic system, electricity transmission and distribution. Used to control, direction, measurement and protection
4、of the live circuit (ie a circuit) schematic run of the equipment, known as the secondary wiring diagram or secondary circuit diagram, also known as the secondary circuit diagram. The main wiring diagram of the plant substation requires a secure, reliable, flexible, economical, relatively strict. Based on the calculated load and capacity you sure you want to choose one or two transformers, and finally to using CAD to draw the small factories substation wiring diagram. Ke
