摘要 PAGE IV 纺织厂10kv供配电设计 摘 要 随着工厂自动化程度的提高，合理的工厂供电系统变得越来越重要，不仅可以保证工厂的正常生产，还能大大的节约电能降低产品的成本，提高生产效率。 本设计为纺织厂供配电系统设计，主要包括电力负荷计算、变电站主接线的设计、电源进线及工厂高压配电线路的设计、短路计算、高低压电气设备选择以及变电站继电保护规划设计和防雷与接地。 同时在设计中采用并联电容器的方法来补偿无功功率，以减少供电系统的电能损耗和电压损失，同时提高了供电电压的质量。从而使整个供电系统更具有其可靠性和灵活性。 关键词：电源进线 短路计算 电气设备选择 继电保护 10kV Power Distribution Design of Textile Factory ABSTRACT With the development of factory automation，power supply system becomes more and more important. It not only can guarantee normal production of the factory ,but also reduce the cost of the products, save the electrical energy and increase productivity. The paper is about the design of the supply and distribution system of a textile factory .It mainly includes the load calculation, the design of substation bus, the design of the inlet line and the high voltage distribution line, short circuit calculation, high and low voltage electrical equipment selection, the layout of the relay protection and the design of the lightning-protection and grounding. At the same time the design uses shunt capacitor to compensation reactive power to decrease energy losses and voltage losses in the power supply system.It can also improve the quality of the power supply voltage. So the whole design of the power supply system becomes more reliability and flexibility.
