Switchyard distribution system design
Abstract
The industrial enterprise supplies power is supply of meaning the necessary electric energy of the factory and distribution question. As everyone knows, the electric energy already easy to change by other electric energy of form, easy to change into other energy of form apt to supply spending, its transport and simple economy of distribution process automation, so, it is extensive that the electric life. Thus do a good job of supplying power in the industrial enterprise to develop to the whole industrial production, realize the industrial modernization has very important meaning. Factory is it designs to be whole important component of factory design to supply power, factory quality designed to supply power influence the production and development of the factory, as personnel that engaged in supplying power in the factory, necessary to understand and grasp factory not to supply power the relevant knowledge designed, in order to meet the need of the design work.
Is it step down to “the Hong Wei” metallurgy mechanical factory switchyard distribution system design in one’s power always to design originally, theoretical foundation that design originally to “supply power technology”, is it study to visit on the spot through Tai-Yuan heavy-duty machinery ling electric power system. Collect various kinds of data, according to “systematic design specification of the distribution with supplying power of industry civilly” of the national standard, and is following: Proceed from the overall situation, make overall plans, according to load nature, electricity, project characteristic and idea of the regional condition of power supply, choose the design plan rationally. “Treating the copper with the aluminum” gets abundant embodiment too in this design proceeds from the angle of economizing energy.
Key Words: It is technological to supply power, Distribution line, Relay protection, Qualify for the next round of competitions and protect
宏伟机械厂35/6KV总降压变电所设计
摘 要
工业企业供电，就是指工厂所需电能的供应和分配问题。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换而来，又易于转换为其他形式的能量，它的输送和分配既简单经济，又便于控制、调节和测量，又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。从而搞好工业企业供电工作对于整个工业生产发展，实现工业现代化具有十分重要的意义。工厂供电设计是整个工厂设计的重要组成部分，工厂供电设计的质量影响到工厂的和生产及其发展，作为从事工厂供电工作的人员，有必要了解和掌握工厂供电设计的有关知识，以便适应设计工作的需要。
本设计是对宏伟机械厂35/6KV总降压变电所及配电系统设计，本设计的理论基础是《供电技术》，并通过太原重型机械厂供电系统的实地参观学习，收集各种数据，按照国家标准《工业与民用供电配电系统设计规范》，并且遵循着：从全局出发，统筹兼顾，按照负荷性质，用电容量，工程特点和地区供电条件的理念，合理选择设计方案。从节约资源的角度出发“以铝代铜”在本次设计中也得到充分体现。
