文档介绍:摘要
设计的课题是110KV野三关变电所。通过本次课题设计,对大学四年的学习进行了全面的总结,达到了巩固专业知识的目的。
变电所为城区及周边城市供电和电厂的上网起到了城区枢纽作用。变电所首先要保证供电可靠,保证对用户不间断供电;其次要求操作灵活,维护方便,接线简单,布置清晰,经济合理。
根据以上变电所设计的要求,设计的110KV变电所的主要内容有:电气主接线的设计;短路电流计算;电器设备的选择;避雷器的选择;户外配电装置的设计;10KV户内配电装置布置;变电所防雷保护设计;主变压器继电保护设计;110KV线路;35KV线路及10KV线路保护设计。
变电所有110KV出线1回,35KV出线8回,10KV出线10回,2台10MVA变压器,变电所所起到了接受电能、分配电能并变换电压的作用,为国民经济的发展和人民生活提供了可靠的有力保证。

Abstract
This paper aims at the design of the 110KV Yesanguan transformer substation. ments the knowledge that the author has learned in the past four years and improves the author's major learning.
The substation's function is pivotal to the power-supply in downtown and around areas and the power station's join to the . The substation should be sure that it can supply power to user continually first. Meanwhile, it need to be quick to be operated, convenient to be maintained, simple to be ,clear to be arranged ,and reasonable to be run.
According to the requirement above, the design includes important aspects as following. The design of the main currency circuit, short circuit calculation, selection of the electrical equipment, selection of BLZ, the design of outdoor power-supply equipment, arrangement of 10KV indoor power-supply equipment, the design of prevention from the under, the design of protection to the continual power-supply, the design of protection to 110KV, 35KV and 10KV circuit.
The substation has a set of 110KV output circuit,8 sets of 35KV output circuit,10 sets of 10KV output circuit, and 2 sets of 10MVA transformers. It can receive currency, arrange electric power and transform electric voltage. Moreover, it ensures to improve the economical development and people's living.
Key words: 110KV transformer substation, short circuit calculation, line protection, distribution equipment, main electrical scheme, transformer.
