摘要
电能是现代工业生产的主要能源和动力,在工业生产中起着十分重要的作用。工业生产实现电气化以后可以大大增加产量,提高产品质量,提高劳动生产率,降低生产成本,减轻工人的劳动强度,改善工人的劳动条件,有利于实现生产过程自动化。但如果工厂的电能供应突然中断,则对工业生产可能造成严重的后果。因此,一个稳定可靠的供配电系统对于发展工业生产,实现工业现代化,具有十分重要的意义。
本文主要进行了负荷计算、主变压器选型、主结线设计、高压配电系统设计、短路电流计算、改善功率因数装置设计、变电所高、低压侧设备选择、变电所防雷装置设计,通过以上步骤设计出了一个可靠、稳定、经济的配电系统。
关键词供配电系统设计,配电网计算,变电所选址
ABSTRACT
Power of modern industrial production of major energy and power, in the industrial production plays an important role. After the electrification of industrial production can greatly increase yield, enhance product quality, increase productivity, reduce production costs, reduce labor intensity and improve working conditions of workers is beneficial to automate the production process. However, if a sudden interruption of the supply of power plant, the industrial production could have serious consequences. Therefore, a stable and reliable power supply system for the development of industrial production, and industrial modernization, is of great significance.
This paper conducted a load calculation, selection of the main transformer, main connection design, high-voltage power distribution system design, short circuit current calculation, improving the power factor device design, substation high and low pressure side of the equipment selection, design of substation lightning protection devices Through these steps to design a reliable, stable and economical distribution system.
Key words distribution system design, puting, location-allocation of substation
