1、 塑料制品厂总配电所及高压配电系统设计 摘要 设计任务来源于指导老师指定的设计题目，设计题目名称是宏昊塑料制品 厂中配电所及高压配电系统设计。设计需做到方案合理、技术先进、运行可靠、 满足相关规范的要求，还要简捷实用、便于操作、管理和维护，减少综合投资。 此次设计的目的是根据本厂所取得的电源及本厂用电负荷的实际情况，并适当 考虑工厂生产的发展，按照安全可靠、技术先进、经济合理的要求，确定变电 所型式，合理进行该厂全厂总降压变电所及高压配电系统设计，确定该厂变电 所变压器的台数与容量、类型选择变电所主接线方案、高低压设备和进出线， 确定防雷接地装置等。 工厂供电系统就是将电力系统的电能降压再分配

2、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。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。 关键词关键词：总配电所，高压配电，塑料制品厂，短路计算，继电保护 The Design of High Voltage Power Substation and Power Distribution System of Hong Hao Plastic Products Factory Abstract The desig

3、n task is originally specified by design instructor, name of which is the design of high voltage power substation and power distribution system of Hong Hao plastic products factory. The program is due to be reasonable, advanced in technology and reliable in operation, which not only meets the requir

4、ements of relevant norms, but also simple and practical, convenient to operate, manage and maintenance, and optimize the overall investment of the design. The design is made as per actual power supply of this factory and actual load of the factory, with considering the development of factory product

5、ion, give a decision about the type of substation, which fulfils the requirements of advanced technology, safe and reliable, economic and reasonable. Design a reasonable factory step-down substation and its high voltage power distribution system, and determine the number, capacity, model of transfor

6、mers in the factory substation, and choose a main wiring scheme for this substation, and also its high voltage and low voltage equipment and incoming and outgoing lines, determine the grounding device and etc. The factory power supply system is the power system of power step-down and distribution of electricity to each plant or workshop, it consists of the factory step- down transformer, high voltage distribution line, workshop substation, low voltage distribution lines and electrical equipment
