摘要课程设计是教学过程中的一个重要环节，通过课程设计可以巩固本课程理论知识，掌握供配电设计的基本方法，通过解决各种实际问题，培养独立分析和解决实际工程技术问题的能力，同时对电力工业的有关政策、方针、技术规程有一定的了解，在计算、绘图、设计说明书等方面得到训练，为今后的工作奠定基础。本设计可分为九部分：负荷计算和无功功率计算及补偿；变电所位置和形式的选择；变电所主变压器台数和容量及主接线方案的选择；短路电流的计算；变电所一次设备的选择与校验；变电所高、低压线路的选择；变电所二次回路方案选择及继电保护的整定；防雷和接地装置的确定；心得和体会；附参考文献。另外有设计图纸4张（以附图的形式给出），分别是：附图一《厂区供电线缆规划图》；附图二《变电所平面布置图》；附图三《变电所高压电气主接线图》；附图四《变电所低压电气主接线图》。由于设计者知识掌握的深度和广度有限，本设计尚有不完善的地方，敬请老师、同学批评指正！关键词：各种计算；变电所的设置；防雷10KVtransformersubstationhostwiringprojectdesignandmainelectricalequipmentchoiceAbstractThecurriculumdesignisinateachingprocessimportantlink,designsthroughthecurriculummayconsolidatethiscurriculumtheoryknowledge,graspsforthepowerdistributiondesignessentialmethod,throughsolveseachkindofactualproblem,raisestheindependentanalysisandsolutionactualprojecttechnicalquestionability,simultaneouslytotheelectricpowerindustryrelatedpolicy,thepolicy,thetechnicalregulationshascertainunderstanding,inaspectsandsooncomputation,cartography,designinstructionbookletisunderthetraining,willlaythefoundationforthenextwork.Thisdesignmaydivideintonineparts:Loadcomputationandreactivepowercomputationandcompensation;Transformersubstationpositionandformchoice;TransformersubstationmaintransformerTaiwannumberandcapacityandhostwiringplanchoice;Short-circuitcurrentcomputation;Atransformersubstationequipmentchoiceandverification;Transformersubstationhighpressure,lowpressurelinechoice;Short-circuitcurrentcomputation;Atransformersubstationequipmentchoiceandverification;Transformersubstationhighpressure,lowpressurelinechoice;Transformersubstationsecondarycircuitplanchoiceandrelayprotectioninstallation;Anti-radarandgroundingdetermination;Attainmentandexperience;Attachesthereference.Moreoverhasdesignpaper4(togivebyattachedfigureform),respectivelyis:Theattachedfigureone"FactorydistrictSuppliesElectricwireCablePlanningdrawing";Attachedfiguretwo"TransformersubstationFloor-plan";Attachedfigurethree"TransformersubstationHighpressureElectricityMainWiringdiagram";Attachedfigurefour"Trans
