1、摘摘 要要 这次毕业设计的主要内容是对某地区 110kV 变电所的设计， 该变电所位于平原地 带，交通方便，无特殊环境污染。该地区最热月平均温度 33 度，年最高气温：40 度 年平均雷电日：90 天最高日平均气温：+33.5 度年最低温度：-2.1 度并且该变电所 有部分系统功率由 110kV 电网经过金岭变电站送至 35kV 高岭变电站， 以 10kV 出线分 别向附近的工厂和居民点供电。 根据所有的条件进行毕业设计，选择主变压器的台数和容量，并进行短路电流计 算，从而进行设备选型和校验，选择合适的断路器、电压、电流互感器，同时介绍了 一些电气设备选择的原则。对主变压器进行保护设计，进一步
2、整定计算，最后规划该 变电所的防雷保护措施，做出完整的 110kV 变电所电气部分设计。 变电站是电网建设的一个重要环节，要以严谨的科学态度来完成设计，保证设计 成果的质量。在本设计中，设计电气主接线时，使其满足了供电可靠、运行灵活和经 济基本需要，并在设计中进行了多个方案的对比，使方案得到了优化，从而在投资方 面节约了，建设方面扩大加强了，并保证在这样的情况下电网能够安全可靠的运行， 这是我们设计的最终目的。 关键词：变压器、短路电流，断路器、电压互感器、电流互感器 1 Abstract The main contents of this graduation design is the d
