焦作吴村纺织厂10kV变电所的设计.docx

河南城建学院本科毕业设计（论文） 摘要 摘要 本文对焦作吴村纺织厂变电站电气部分进行了设计，按照变电站设计规范和电力设计手册，结合对焦作吴村纺织厂变电站的基础资料的分析，以及确认当地的供电条件及设备的用电要求，进行了本次变电所设计。 本设计首先通过需要系数法进行了负荷计算，在确定功率因数后，进行了无功补偿。以原始资料和生产实际为依据，以变电站按最佳方式运行为基础，在充分考虑了工厂设备的总容量及负荷等级，并结合工厂未来的发展需求和变压器的最佳运行状态后，严谨按照国家相关设计规范，完成了变压器及主接线的选择方案。继而根据设计的主接线进行开关柜的选择，并结合主接线形式，确定基准值，采用标幺值法进行了短路电流计算，从而完成了一次设备部分的选型及计算。在变电所二次回路部分，通过选择各线路导线截面和变电所高低压设备配置了继电保护装置、防雷和接地装置，最终绘出设计图样，完成了焦作吴村纺织厂的供配电统设计。 关键词：短路电流，电气主接线，负荷计算 Abstract Electric energy is the main energy and power of modern industrial production. It is of great significance to do well the design of power supply for developing industrial production and realizing industrial modernization. First of all, the power supply system of the factory should be able to meet the needs of production and living electricity. It should be safe, reliable, technologically advanced and economically reasonable, and do well in energy saving. This design according to the factory can obtain the power supply and the actual situation of the plant power load, and appropriate consideration of the development of production, according to the basic requirements of the plant power supply, the load calculation and reactive power compensation for each workshop; Determine the position of each substation and the number, quantity and type of each transformer station; The short-circuit current is calculated. Selects each line conductor cross section and substation high and low voltage equipment is equipped with relay protection device, lightning protection and grounding device; Draw out the design pattern, complete the plants power supply and distribution system design. In this paper, the electrical part of the substation of Jiaozuo Wucun Textile Mill was designed in accordance with the substation design specifications and electric power design manual. Based on the original data and production practice, based on the best way to run the substation, under the premise of full consideration of the future development of the factory, through practical
