供用电工程课程设计说明书百货大楼供电设计院、部:电气与信息工程学院学生姓名:蒋鹏指导教师:桂友超职称副教授专业:电气工程及其自动化班级:电气本1205班完成时间:2016年1月摘要随之国民经济的发展,电能是现代生产的主要能源和动力。电能既易于由其它形式的能量转换而来,又易于转换为其它形式的能量以供应用;电能的输送的分配既简单经济,又便于控制、调节和测量,有利于实现生产过程自动化。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。电在现代生活中起到的作用越来越重要。一个百货大楼的供电对一个百货大楼十分重要,它是保证百货大楼正常运行的重要基础。本次设计首先分析了本次供用电工程课程设计的设计要求。进行了负荷计算、变电所选址与结构、变压器类型、变电所主接线、短路计算、设备选择校验、电缆选择。证明了完成设计任务要求,满足设计的技术参数要求。关键词:百货大楼;供用电;校验ABSTRACTAlongwiththedevelopmentofthenationaleconomy,electricityisthemajorenergyandpowerofmodernproduction.Poweriseasytoconvertfromotherformsofenergy,butalsoeasytoconverttootherformsofenergysupply;thedistributionofpowertransmissionissimpleandeconomic,andeasytocontrol,regulationandmeasurement,thereisconducivetotherealizationoftheproductiontheprocessofautomation.Therefore,thepowerinmodernindustrialproductionandthelifeoftheentirenationaleconomyinawiderangeofapplications.Moreandplayaroleinthemodernlifeoftheelectricpowersupplymoreimportant.Astorebuildingisveryimportantforadepartmentstore,itisanimportantfoundationtoensurethenormaloperationofthedepartmentstore.Thedesignbeginswithananalysisofthedesignofthepowersupplyengineeringcurriculumdesignrequirements.Foraloadcalculationandsubstationlocationandstructure,typeoftransformersubstationmainwiring,short-circuitcalculation,equipmentselectionandcheck,cableselection.Proofofcompletedesigntaskrequirements,technicalparameterssatisfythedesignrequirements.KeywordsDepartmentstore;supplyofelectricity;Checkout目录1负荷等级确定与供电电源..........................................................................................................................11.1负荷等级确定..................................................................................................................................11.2供电电源..........................................................................................................................................12负荷计算与无功补偿..................................................................................................................................22.1负荷计算..........................................................................................................................................22.2无功补偿..........................................................................................................................................32.3总计算负荷......................................................................................................................................33变(配)电所所址选择与结构型式..........................................................................................................43.1所址选择..........................................................................................................................................43.2结构型式..........................................................................................................................................44变压器类型、台数及容量选择..................................................................................................................54.1变压器类型选择..............................................................................................................................54.2变压器台数选择..............................................................................................................................54.3变压器容量选择..............................................................................................................................55变(配)电所电气主接线设计..................................................................................................................65.1高压系统电气主接线设计..............................................................................................................65.2低压系统电气主接线设计..............................................................................................................65.3低压配电网的接线形式..................................................................................................................76短路计算与电气设备选择校验..................................................................................................................86.1短路电流计算..................................................................................................................................86.2高压电气设备选择校验................................................................................................................106.3低压电气设备选择校验................................................................................................................107进出线电缆选择校验................................................................................................................................127.1高压进线电缆选择校验................................................................................................................127.2高压出线电缆选择校验................................................................................................................127.3低压进线电缆选择校验................................................................................................................12结束语..................................................
