I摘 要本文根据任务书上所给负荷以及相关设计需求，首先提出几种主接线方案并进行选择比较，选出最经济、可靠的主接线方式，接着通过变电所的设计规则和相关注意事项以及实际负荷确定主变压器的台数、容量、型号。然后通过最大持续电流以及短路电流计算对母线、断路器、隔离开关、电压互感器、电流互感器等电气设备进行选择和校验。最后画出电气主接线图，从而完成110kV 变电所一次部分的设计任务。关键词 110kV 变电所，短路电流，设备选型，设备校验IIAbstractThis paper according to the task book to load and related design requirements, first proposed several main wiring scheme and the selection, choose is the most economical and reliable way to the main terminal, followed by changing the design rules and related matters needing attention and the actual load to determine main transformer units, capacity, model. Then, the maximum continuous current and short-circuit current of the bus, circuit breakers, isolation switches, voltage transformers, current transformers and other electrical equipment for selection and verification. Finally, the electrical main wiring diagram is drawn, so as to complete the design task of the 110kV substation.Key Words Substation, short-circuit current, equipment selection, calibration1目 录Abstract............................................................................................................II第一章 绪论............................................................................................- 1 -1.1 课题的意义................................................................................- 1 -1.2 国内外发展现状：....................................................................- 2 -第二章 110kV 变电所所址选择及电气主接线的选择........................- 4 -2.1 电气主接线的设计规范............................................................- 4 -2.1.1电气主接线的设计原则：................................................- 4 -2.1...
