内容摘要
本设计共有四部分：第一部分为设计任务书；第二部分毕业设计（论文）说明及计算书；第三部分为变电站的其他规划；第四部分为设计图纸。
此次设计的是一个降压变电所，有三个电压等级，主变容量为2X31.5MVA。110KV主接线为双母线、35KV和10KV主接线均为单母分段 ，本次设计中进行了主接线的方案论证、短路电流计算、主要电气设备的选择有断路器、隔离开关、母线、PT、CT等的选择及校验。
Abstract
The tentative design for 110kv power substation
The design is made up of four parts: part one, the design specification; part two, the prospectus of the design and the calculations of the design; part three,construction of power substation; part four, the design drawing.
The design concerns a step-down substation of three voltages with the main capacity of 2X31.5MVA. Its main line of 110KV is a two-way bus, and the other two of 35KV and 10KV are both one-way bus line sections. As for the design, the thesis has verified its wiring project, calculated its short-circuit current, selected and tested its main electrical equipments like the circuit breaker, the disconnecting switch, the bus line, PT, CT, etc.
