内容简介：

摘 要众所周知，电能是现代工业生产的主要能源和动力，电能既易于由其他形式的能量转化而来，又易于转化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。现代社会的信息技术和其他高新技术都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。本次设计是在“安全、合理、优质、经济”的设计要求之上，切实保证工厂生产和生活用电的需要，并做好节能工作。在设计的过程中合理地处理了局部和全局、当前和长远等关系。既照顾局部和当前的利益，又顾全大局，适应发展。本次设计包括电力负荷及其计算，短路电流及其计算，工厂变配电所及其一次系统设计，工厂高压电气设备的选择，工厂供电系统的继电保护及二次接线等五大部分的内容。由于时间的关系，防雷与接地这块内容没有涉及。本次设计在变压器的选择，导线选择，微机保护和供电自动化等方面，作了一些新的论述，相应的补充了有关的技术资料。本设计注重理论结合实际，在设计的过程当中穿插了我国的最新标准规范，同时为了更好的有关专业术语和符号的含义，对部分专业术语在首次出现时加注了英文。在设计的过程中，为了更好的联系实践，还到巨化的电化厂，锦纶厂等相关工厂实地考察了他们的高配设计，还请相关的技术人员加以指导。限于本人的知识水平和实践经验，错漏在所难免，敬请原谅。关键词：自动化；配电系统；短路电流；无功补偿；继电保护；备自投；二次接线等 ABSTRACT As we all know, electricity is the major energy and modern industrial production momentum generated by both easy conversion from other forms of energy, it is also easy to translate into other forms of energy supply; Electric transmission and distribution simple economy, and ease of control, regulation and measurement, is conducive to the production process automation. Modern society is the establishment of it and other high-tech applications in the energy basis. Therefore electricity in the modern life of the entire national economy of industrial production and applications extremely broad. This design is in a safe and reasonable, high-quality, and economy on the design requirements, and ensure that the electricity needs of factory production and living, and doing conservation work. In the design process to address the local and generic reasonable, such as current and long-term relationship. Both for local and current interests, and overall, to development. The current design includes electricity load and calculated short circuit currents and its terms, and the factory has a distribution system design, high voltage electrical equipment factory options factory electricity wiring system relay and second five most of the content. Because of time, the contents of this mine and grounded not covered. This design choice in transformers, wire options such as automated computer protection and electricity, a new exposition on the corresponding additional technical information. The design emphasis on integrating theory with practice in the design process insert our latest standard norms, and to better the professional terminology and the meaning of symbols, for some professional terms, for the first time in the English word. In the design process, in order to better link practice, but also to the electronic giant of plants, polyamide fiber plant, and other related plant site visits with their high design, and requests related to the technical staff guidance. I limited to the knowledge and practical experience, errors inevitable, ask forgive
