1、 I 摘 要 本次 60kV 变电站电气部分设计， 首先对变电站变压器的负荷计算和无功补偿 进行了系统的计算，其中通过对变电所的负荷状态和自然条件来对负荷计算进行 系统的计算分析， 而电容器组总容量的确定是对补偿电容器进行计算的前提条件。 其次确定了主变压器的台数、型式和容量。对电气主接线的选择，通过计算分析， 确定了接线方式。短路计算是本次电气设计重要的环节，因为它对电气主接线、 电气设备、继电保护、接地方式的选择都起到了至关重要的作用。电气设备要从 母线、断路器、隔离开关、互感器等几个方面选择出最佳方案。继电保护主要分 为变压器差动保护、瓦斯保护、过电压保护、过电流保护，通过比较计算选择最
2、 好的保护方式。防雷保护是通过分析计算来确定避雷针高度以及它的保护范围。 最后确定变电站的配电装置和电气平面的总布置。 关键词：变压器；短路计算；继电保护；防雷保护 II Abstract The design of 60kv electric substation and transformer substation caculated the load calculation and reactive power compasition in the first place. Whats more, though the caculation of the substations load
3、 state and natural conditions,we can make a load caculation of the system. While,the determination of the total capacity of capacitors is the pre-condition to caculate the compensation capacity. In the second place, it makes sure of the number,tape and capacity of the main transform substation. The
4、choice of main electrical wiring is through the caculation analysis to determine the connection mode. Short circuit caculation is the crucial link of the electrical design. Because it plays an important role in making thd choice of the way of grouding, electrical wring,electrical equipment and relay protection. The electric equipment must choose from the aspects of bus,breakers,isolating switch transformer as the best method. The relay protection is mainly devided into transformer differental
