某车间低压配电系统附变电所供配电系统.docVIP

摘 要 电能是工业生产的主要动力能源，工厂供电设计的任务是从电力系统取得电源，经过合理的传输、变换、分配到工厂车间中每一个用电设备上，随着工业电气自动化技术的发展，工厂用电量快速增长，对电能质量、供电可靠性以及技术经济指标等的要求也日益提高，供电设计是否完善，不仅影响工厂的基本建设投资、运行费用和有色金属消耗量，而且也反映到工厂的可靠性和工厂的安全生产上，它与企业的经济效益、设备和人身安全等是密切相关的。 本说明书为某车间及变电所供配电系统设计说明，该车间的电压等级分别为10kV和0.4kV，车间的负荷均属三类负荷，根据设计任务书的要求，本设计的主要内容包括：车间的负荷计算及无功补偿，确定车间变电所的所址和型式，车间变电所的主接线方案，短路电流计算，车间照明系统设计等。 关键词： 供配电 负荷计算 无功补偿 照明系统  Abstract Electric power industrial production is the major energy, power plant design, the task is to obtain power from the power system,through reasonable transmission, transformation, distribution to the factory workshop every electrical equipment, with the industrial electrical automation technology development, the rapid increase of electricity consumption of the plant, power quality, power supply reliability and technical economic indicator requirements are also increasing, the power supply design is perfect, not only affect the plants basic construction investment, operation cost and nonferrous metal consumption, but also to reflect the reliability and plant safe production, it is the economic efficiency of enterprises, equipment and personal safety, is closely related to the. The specification for a workshop and transformer substation of power supply and distribution system design, the workshop and the voltage levels were 10kV and 0.4kV, workshop load is three class load, according to the requirements of the mission design, the design of the main contents include: workshop load calculation and reactive power compensation, determine the substation in the workshop of site and type, plant and substation main wiring scheme, short-circuit current calculation, workshop lighting system design. Keywords: power supply load calculation of reactive power compensation lighting system 目 录 第1章 绪 论 - 1 - 1.1 设计目的 - 1 - 1.2设计范围 - 1 - 1.3设计程序 - 1 - 1.4设计原则 - 2 - 第2章 车间的负荷计算及无功补偿 - 3 - 2.1 负荷计算 - 3 - 2.2 无功补偿 - 4 - 第3章 确定车间变电所变压器的型式、容量及数 - 7 - 3.1确定车间变电所主变压器的型式 - 7 - 3.2 变电所主变压器台数和容量的确定 - 7 - 第4章 一次设备选择
