要完成的内容画出牵引降压混合变电所的主接线。牵引变电所的主接线由交流中压开关设备、牵引整流机组、直流开关设备等几部分组成；降压变电所主接线由交流中压开关设备、配电变压器、交流低压开关设备等几部分组成。主接线应满足可靠性、灵活性和经济性的基本要求，所以在牵引变电所和降压变电所能合建时尽量合建。本课设的相关设计就是两者合建时最合理的主接线的设计。2 设计分析2.1 外部电源选择城市轨道交通系统的外部电源方案，根据城市电网构成的不同特点，可采用集中式、分散式、混合式等不同形式。究竟采用何种方式，应通过计算确定需要负荷之后，根据城市轨道交通路网规划、城市电网构成特点、工程实际情况综合分析确定。但通常采用混合式供电方式，即以集中式供电为主，个别地段引进城市电网电源作为集中式供电的补充，使供电系统更加完善和可靠。2.2.1 设置方案 1

母线一般有两种方案：一是两套牵引整流机组进线合并，二是两套牵引整流机组进线独立。其中方案二：正常运行时，两套牵引整流机组同时投入；故障状态下，当其中一套牵引整流机组退出运行时，另一套牵引整流机组在其允许过负荷情况下可继续运行，否则由相邻牵引所实现对牵引网的越区支援供电，管理和操作较复杂；并且套牵引整流机组设备及保护配置相互独立，故障易判断。两套牵引整流机组分别通过一台35kV 断路器，并接在同一段 35kV 母线上。图 3 整流机组接线图3 主接线图绘制3.1 电源侧主接线当牵引变电所只有两回电源进线和两台主变压器时，常在电源线路间用横向母线将它们连接起来，即构成桥形接线。根据中间横向母线的位置不同而分为内桥接线和外桥接线两种，前者的桥接母线连接在靠变压器侧，而后者则连接在靠线路侧。内桥接线适用于线路故障较多的场所，外桥接线适用于变压器故障较多的场所，而变压器又不需要频繁的操作，故在此选内桥接线如图4 所示。文档编码:CA4N7K2V1F8

直流侧主接线直流侧主接线按照母线形式有单母线系统，双母线两种主要形式，因设备配置及运行方式的差异，可以演变出多种形式。常用的有以下四种：(1 A 型单母线系统，进线为直流断路器，设置纵向电动隔离开关；(2 B 型单母线系统，进线为电动隔离开关，设置纵向电动隔离开关；(3 C型双母线系统，进线为直流断路器，不设置纵向电动隔离开关；(4 D 型双母线系统，进线为直流断路器，设置纵向电动隔离开关。A 型单母线系统由于隔离开关的电气特性，使纵向电动隔离开关的操作限制条件较多，操作判断时间较长，正常双边供电转为大双边供电时间也较长。但其无论是在牵引整流机组、直流进线、直流母线、直流馈线开关故障或检修推出时，均能实现不影响直流牵引供电系统运行的要求，系统运行的可靠性高，造价较低。故本课设采用的直流侧主接线是A 型单母线系统。3.3 牵引变压器主接线在变电所中采用三相YN,d11 牵引变压器，当采用直接供电方式时，原边绕组接成 Y 接线，低压侧两边绕组，各取一端联至27.5kV 的 a相和 b 相母线上，他们的公共端接至接地网和钢轨。三相双绕组YN,d11 接线牵引变电所如下图5所示。文档编码:CA4N7K2V1F8 HM10V10A6X2F2 ZY8Q5I4W6P6文档编码:CA4N7K2V1F8 HM10V10A6X2F2

环网设备已逐步走向国产化。在这种形势下，我国城市轨道交通领域，在供电系统中压网络方面，应拓宽思路，认真研究，积极探讨采用20kV 牵引动力照明混合网络的工程实施，尤其是对那些新建城市轨道交通的城市。参考文献1 南昌地铁 1号线供电系统投标文件G.中铁二院工程集团有限责任公司.成都,2009.2 杭州地铁1号线初步设计文件R.中铁二院工程集团有限责任公司.杭州,2008.3GB 50157-2003
