某工厂供配电系统设计设计..doc

摘 要 工厂供电，是指工厂所需的电能的供应与分配，也称工厂配电。 众所周知，电能是现代工业生产的主要能源和动力。电能既能易于由其他形式的能量转换而来，而易于转换为其他形式的能量以供应用。电能的输送和分配既简单经济，又便于控制、调节和测量，有利于实现生产过程自动化，而且现代社会的信息技术和其他高新技术无疑不是建立在电能应用的基础之上的。因此电能在现代工业生产及整个国民经济生活中应用极为广泛。 本论文设计首先计算电力负荷和变压器的台数、容量；利用所学的知识确定变电所的位置。计算出短路电流的大小，选出不同型号的变压器，进而确定变压器的连接组别，画出必要的变电所主接线图。 关键词：主接线图、短路电流、电力负荷、变压器 Abstrat The factory power supply, it is to point to the factory power supply and distribution, also called plant distribution. As is known to all, the electricity is of modern industrial production, the main form of energy and power. Electric energy can easily by other forms of energy conversion, and easy to convert to other forms of energy to supply the use. Electric power transmission and distribution of economic is simple, and easy to control, adjust and measurement, which is helpful to realize the production process automation, and the modern social information technology and other high-tech undoubtedly is not based on electric power on the basis of application of. So the power in the modern industry production and the whole national economic life are widely. This thesis design first calculated power load and transformer sets, capacity; Use knowledge to determine the position of the substation. To calculate the short circuit current size, choose different types of transformer, and then determine the transformer connection categories, draw the necessary substation main wiring diagram。 Keywords: main wiring diagram, short circuit current, power load, transformer 目录 第1章 前言 ………………………………………………………………………………4 第2章 设计任务 …………………………………………………………………………5 2.1 原始资料 ……………………………………………………………………………5 2.2 工厂平面图 …………………………………………………………………………5 2.3 工厂供电电源 ………………………………………………………………………5 2.4 工厂负荷情况 ………………………………………………………………………6 2.5 设计要求 ……………………………………………………………………………7 第3章 全厂负荷计算和无功功率补偿 …………………………………………………8 3.1 负荷计算 ……………………………………………………………………………8 3.2 无功功率补偿 ………………………………………………………………………11 第4章 变电所高压电器设备选型 ………………………………………………………12 4.1 主变压器的选择 ……………………………………………………………………12 4.2 各个车间变压器的选择 ……
