为您解答如下:天津某化纤毛纺厂供电系统设计 摘 要 本设计旨在通过对天津某化纤毛纺厂供配电系统的设计使设计者了解掌握工业企业供电系统的设计过程及其基本技能,在设计过程中不但加深了对供配电这门技术的理解,还培养了对理论知识灵活应用能力。设计过程包括:负荷计算、方案论证、短路计算、设备选择、无功补偿及变配电所的设计等。此污水处理厂为二级负荷,有两路电源进线,厂区内共设两个降压变电所(35KV/10KV).(10KV/0.4KV)。因供电电源要求功率因数大于0.9,因此通过在低压侧加电容进行补偿使之达到要求。通过负荷计算和对各短路点的电流计算选择设备,使之满足要求。在设计过程中充分考虑了供电系统的可靠性与安全性,并力求使之经济合理。关键词:变电所;变压器;负荷计算;短路计算;照度计算;功率补偿苏州某研发中心大楼电气设计摘 要 本设计为苏州某研发中心大楼的电气设计。电气设计遵循《民用建筑电气设计规范》(JGJ16-2008),并符合国家现行的其他规范和标准。根据建筑的规模大小和功能需求,查询规范知,该建筑属于高层民用建筑,建筑类别为一类建筑,耐火等级为一级,防雷等级为二级,一般照明采用三级负荷供电,消防用电和重要负荷采用一级负荷供电,低压配电系统的接线方式采用TN-C-S。防雷系统设计采用避雷网。该建筑电气设计包括两部分:强电系统设计和弱电系统设计。其中强电部分包括低压配电设计、照明系统设计、防雷与接地系统设计;弱电部分包括消防系统设计、有线电视系统设计、电话系统设计、网络系统设计、安防系统设计。设计中要根据建筑的规模、使用要求及设计原则,计算得出相应的技术指标,并进行导线及设备的选型,使之满足经济合理性及节能要求,保证供电的可靠性。关键词:低压配电;照明;消防;防雷与接地Tianjin a certain chemical fiber woolen mill power supply system design Pick to This design aims to through the design of a certain chemical fiber woolen mill power supply system in tianjin to designers to grasp the design process of industrial enterprise power supply system and its basic skills, in the design process not only deepened the understanding of power supply this technology, and train the ability of the flexible application of theoretical knowledge. The design process include: load calculation, short circuit calculation, equipment selection, project demonstration, reactive power compensation and distribution design, etc. The sewage treatment plant as the secondary load, there are two way power supply into line, the factory have two step-down substation (35 KV / 10 KV). (10 KV / 0.4 KV). Because of the power supply for power factor more than 0.9, so through in low voltage side capacitance compensation to meet the requirements. Through load calculation and selection for the current calculation of short-circuit point equipment, to meet the requirements. In the design process fully consider the security and reliability of power supply system, and strive to make economic sense. Key words: substation; Transformer; Load calculation; Short circuit calculation. Intensity of illumination computation; Power compensation A research and development center building electrical design in suzhou Pick to This design for a research and development center building electrical design in suzhou. Electrical design follow the civil construction electrical design specification (JGJ16-2008), and other specifications and conform to the current national standards. According to the scale of construction and the function demand, query, the building belongs to the high-rise civil buildings, category for a class of buildings, fire resistance rating for level 1, level of lightning protection for the secondary, general lighting use level 3 load power supply, fire power and important load using level load power supply, the connection mode of low-voltage distribution system adopts TN - C - S.
