炼染厂总降变电所及供配电系统设计.doc

摘 要 电能是现代工业生产的主要能源和动力。电能容易转化为其他形式的能量以供应用，并且电能的输送和分配既简单经济又便于控制和测量，有利于实现生产过程自动化。电能在工业生产中的重要性，在于工业生产实现电气化后可以大大增加生产，提高产品质量降低生产成本，有利于实现生产过程自动化，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。做好工厂供电工作对于发展工业生产具有十分重要的意义 本毕业设计为沈阳炼染厂总降变电所及供配电设计。对供配电设计所涉及的内容：供电设计的一般原则和意义，负荷计算和无功补偿、变配电所及主变压器的选择、变配电所主接线方案的设计、短路计算及一次设备的选择、继电保护及二次回路的选择、变电所的布置与结构设计、供配电线路的设计计算、防雷 保护和接地装置的设计等进行了阐述。 关键词：配电系统，主接线，负荷计算，短路电流 ABSTRACT The electricity is the main energy and power of modern industrial production. The electricity is easy to translate into other forms of energy , and power transmission and distribution are both simple and convenient for economic control and measurement, which is helpful to realize the automatic production process.The importance of electric power in the industrial production lies in the truth that the electricity can greatly increase production, improve product quality to reduce the production cost, which is helpful to realize the automatic production process.Therefore, the electric power are widely used in the modern industrial production and the entire national economy in life . Factory work for development power supply to industrial production has the very vital significance The graduation design is shenyang refining enterprise total drop substation and power supply design. The contents of the design are as follows: the principles of and meanings of power supply design,the load calculation and reactive power compensation, the choice of main transformer, the choice of the main wiring schemes design, short circuit calculation and the choice of equipment , relay protection and the choice of the secondary circuit, substation arrangement and structure design, the design and calculation of supply distribution circuit , lightning protection and grounding device design . Keywords: the distribution system, the main connection, load calculation, short circuit current 目 录 摘要.......................................
