电气工程论文 摘要：本毕业设计为XXXXXXXX学院二○○三级电气工程及其自动化专业（本科）毕业设计，设计题目为：35KV变电所扩大设计。此设计任务旨在体现对本专业各科知识的掌握程度，培养对本专业各科知识进行综合运用的能力，同时检验本专业学习四年以来的学习结果。 首先根据任务书上所给系统与线路及所有负荷的参数，分析负荷发展趋势。从负荷增长方面阐明了建站的必要性，然后通过对拟建变电站的概括以及出线方向来考虑，并通过对负荷资料的分析，安全，经济及可靠性方面考虑，确定了35kV变电所用电的主接线，然后又通过负荷计算及供电范围确定了主变压器台数，容量及型号，同时也确定了站用变压器的容量及型号，最后，根据最大持续工作电流及短路计算的计算结果，对高压断路器，隔离开关，母线，绝缘子和穿墙套管，电压互感器，电流互感器进行了选型，从而完成了35kV变电所电气的设计。 关键词： 35KV变电所；变压器；设计 Abstract:This graduation project for Zhejiang science and technology institute 2003 level of electrical engineerings and automation specialized (undergraduate course) graduation project, designs the topic is: 35KV transformer substation expansion design.This design duty is for the purpose of manifesting to this specialty various branches knowledge grasping degree, raises carries on the synthesis utilization to this specialty various branches knowledge ability, since simultaneously has examined this specialty to study four year the study results. First acts according to in the project description to give the system logical circuit and all load parameter, the analysis load trend of development.Had expounded from the load growth aspect the station construction necessity, then through to plans to construct the transformer substation the summary as well as the going beyond a line direction considered, and through to shoulders the material the analysis, safe, the economy and the reliable aspect considered, had determined the 35kV transformer substation uses electricity the main wiring, then calculated through the load and supplies power the scope to determine the main transformer Taiwan number, the capacity and the model, simultaneously also had determined stood with the transformer capacity and the model, finally, according to the most greatly continually operating current and the short circuit computation computed result, to the high-pressured circuit breaker, the isolator, the generatrix, the insulator and put on the wall drive pipe, the voltage transformer, the current transformer has carried on the shaping, thus completed35kV transformer substation electricity design. Keywords：35KV substation；transformer；design
