1、主接线采用单母线放射式接线方案。根据设计中提供的负荷进行负荷电流的计算，对电动机进行额定电流估算，以选择电力电缆、车间母线、电气设备、继电保护装置、馈出线路的导线，保证母线和用电设备的安全可靠的运行。继电保护装置的选择是动力配电的主要部分，设计中设置了电流速断保护、欠电压保护、过电压保护，失电压保护及过载保护，这样能够保证在过负荷或短路时，将故障迅速切除，为了提高供电的可靠性，采用了单台设备独立保护的方法，尽量将故障范围缩为最小。平面布置图展示了整个车间的动力，照明及弱电系统的设备和线路的分布。关键字：配电；车间配电；配电装置；继电保护 Abstract： The substance of t

11、的要求的也越来越高，近年来我国电器产品出口量增长迅速，产品出口创汇逐年增加，其主要原因一是改革开放以来，通过技术引进和消化吸收，我国电器行业技术装备水平不断提高，提高了高效照明电器产品的质量；二是发达国家产业结构调整，将大量消耗能源、资源及劳动力密集型的产品转移到发展中国家生产，利用发展中国家的廉价劳动力和资源，购买产品，满足他们的市场需求。要充分利用这一有利时机，借助我国加入世贸组织的机遇，采取措施，扩大我国电器产品的国际市场份额，增强我国电器行业的国际竞争力。具体要做好以下方面工作：一是要加快实施电器企业战略性重组，优化资源配置。抓住当前国家实施产业结构调整之际，加快实施企业战略性重组，优

12、化资源配置。节能工作只有将社会效益与经济效益相结合，与保护环境、提高生活质量相结合，才能得到全社会的支持与响应，变成全社会的行动。采用新的节能高效的电器设备是一项社会系统工程，需要充分发挥政府、中介组织、科研院所和企业等各方面的积极性，共同努力推动工程的健康发展。本设计本着节能，经济的设计原则来选择设备和导线，尽量避免不合理的施工方式。做到实用，经济，节能，环保以及运行和维护的方便。第1章动力配电的设计1.1动力配电方案的初步设计1.1.1供电的要求车间的配电担负着该车间的动力、照明及弱电系统的电力负荷，是工厂供电系统的枢纽，在工厂中占有特殊重要的地位。电能是现代化生产中主要的动力和能源，如果工厂供电突然中
