6、际问题。3、初步掌握电气工程专业（二次部分）工程设计的流程和方法，独立完成设计任务，并能通过答辩。4、端正态度，树立严肃认真、实事求是和刻苦钻研的工作作风。第29页共24页教师批阅课程设计用纸二总体设计内容—110kV无人值班终端变电所二次部分设计1、110KV进线、35KV出线、10KV出线保护的配置、出口方案；2、110KV进线2保护的整定计算；3、10KV侧遥控、遥信、遥测测量点选择表；4、10KV分段开关柜端子排图；5、10KV线路电流、电压回路图。三电气一次部分设计的基本情况1、工程规模：该变电所为110/38.5/10.5KV三级电压，所内装设31

7、.5MVA及40MVA主变各一台，2回110KV架空进线，4回35KV出线及8回10KV出线。变电所配有10KV无功补偿装置。2、主接线考虑110KV侧采用内桥接线方式，35KV单母分段带旁母，10KV单母分段。3、所用电配置：一台由10KV母线接出，另一台由35KV外来所用电取得。4、防雷与接地：110KV进线侵入雷电波的保护是在架空线首端装一组避雷器，并配合进线上的相应保护。主变中性点装设一组避雷器及设间隙保护。35KV和10KV母线分别装设避雷器作为出线侵入的雷电波保护。直击雷由避雷针保护。5、主要参数：第29页共24页教师批阅课程设计用纸1）、系统参数
