工厂kv总变电所及配电系统设计精要.doc

洛阳理工学院毕业设计(论文) I 工厂 10kv 总变电所及配电系统设计摘要工厂供电系统就是将电力系统的电能降压再分配电能到各个厂房或车间中去,它由工厂降压变电所,高压配电线路,车间变电所,低压配电线路及用电设备组成。工厂总降压变电所及配电系统设计,是根据各个车间的负荷数量和性质, 生产工艺对负荷的要求,以及负荷布局,,经济技术的分配电能问题。其基本内容有以下几方面:进线电压的选择,变配电所位置的电气设计, 短路电流的计算及继电保护, 电气设备的选择, 车间变电所位置和变压器数量、容量的选择,防雷接地装置设计等。本设计在对化工厂进行供配电调研、论证的基础上,完成了化工厂的负荷计算,无功功率补偿,变配电所位置和型式选择, 10KV 变配电所主接线设计;还进行了短路电流计算、电气设备的选择与校验。最后对化工厂的变压器进行了保护和供电系统的防雷。关键词:变电所,负荷,短路电流,电力设备洛阳理工学院毕业设计(论文) II C HEMICAL T OTAL SUBSTATION AND DISTIBUTION SYSTEM DESIGN ABSTRACT Factory power supply system is the redistribution of power system power step-down power to each plant or shop floor to itby the factory step-down transformer substation, high voltage distribution lines, plant and substation, low voltage distribution lines and electrical position. The total plant step-down substation and distribution system design is based on the load of each number and nature of the workshop, the production process on the load requirements, and load distribution, combined with the national electricity supply. Address the various departments of the safe, reliable, economic and technological The distribution of electric energy issues. The basic contents of the following areas: ing line voltage selection, the location of the electrical substation design, calculation and short circuit current protection, electrical equipment selection, the number of plant and transformer substation location and capacity choices lightning protection grounding design. The design of power distribution in the chemical plant for research, demonstration, based on pletion of the chemical load calculation, reactive pensation, power distribution by location and type selection, 10KV substation main wiring design; also conducted short-circuit current calculation, electrical equipment selection and validation. Finally, chemical plants and power transformer protection lightning protection system. KEY WORDS: substation , load , short-circuit current, power equipment 洛阳理工学院毕业设计(论文) III 目录前言....
