根据设计任务书的要求，本次设计为110kV 变电站电气一次部分初步设计，并绘 制电气主接线图及其他图纸。该变电站设有两台主变压器，站内主接线分为110kV、 35kV 和10kV 三个电压等级。各个电压等级分别采用单母线分段接线、单母线分段带 旁母接线和单母线分段接线(From the guide of engineering design assignment, we have to design primary power-system of 110kV substation and draw main electrical one-line diagram and others. There are two main transformer in the substation in which main electrical connection can be divided into three voltage grades: 110kV, 35kV with 10kV.It deposits sectionalized single bus bar scheme, sectionalized single and transfer bus bar and sectionalized single bus bar scheme per grade.)
