毕业设计---某水泥厂110kV总降压变电所的设计

1、毕业设计（论文） I 某水泥厂 110kV 总降压变电所的设计 摘 要 本文主要是针对某水泥厂 110kV 变电所进行设计。根据变电所周边地区提供 的负荷及对供电系统的要求，本次设计主要内容是对供电系统进行负荷计算，对 总降压变电所及配电系统进行设计。并对主要设备进行选型校验，对主变压器、 线路进行保护整定计算，对主、变线路进行防雷保护等。在这次设计中，负荷计 算是非常重要的，根据计算结果，可以选择供电系统中线路的变压器的型号、导 线截面、电压和电流互感器等主要电气设备。变压器在供电系统中也是重要的设 备，掌握了对它的保护和整定计算方法。 通过本次毕业设计，旨在熟悉变电所中供电系统的负荷计算，

2、掌握变电所中 一次回路的基本原理，在此基础上对供电系统中的变电所一次接线进行了设计和 计算，最后根据具体环境条件对电气设备进行校验，使本次毕业设计的内容更加 完善。 关键词关键词：一次部分，变电所，变压器，电气设备 毕业设计（论文） II The design of major system of 110kV substation ABSTRACT A cement plant substation of 110kV is designed in this Paper. A substation of 110KV is designed in this Paper. According to

3、the substation and the request of the power supplying system, I mainly design and calculate the major system, check to the main equipments, and design the protection of the circuit etc. Burden calculation is very important in this design. We can choice the transformer, the circuit and the other main

4、 electricity equipments. We should learn the method of the calculation of it. Transformer is also very important，we should learn how to calculate and how to protect it. I will acquaint with the burden calculation of the substation pass this graduation design，and learn the basic principle of the major system in the substation. I have completed the design and the calculation，and I will check it basis the actual environment .And then this graduation design will be perfect. KEY WORDS: Major system，T
