摘要
随着城市化的发展，城郊已经纳入城市的发展规划，供电方面要求越来越高，特别是供电的安全性、可靠性和持续性。电网的安全性、可靠性和持续性往往取决于变电站的合理设计和配置。一个典型的变电站要求变电设备运行可靠、操作灵活、经济合理、扩建方便。本论文设计了一个降压变电站，此变电站有三个电压等级：高压侧电压为110kV。中压侧电压为35kV，有八回出线。低压侧电压为10kV，有十四回出线。同时对于变电站内的主要设备进行合理的选型。本设计选择选择两台SFSZ1163000110主变压器，其他设备如断路器、隔离开关、电流互感器、高压熔断器、电压互感器和继电保护装置等等也按照具体要求进行选型、设计和配置，力求做到运行可靠，操作简单、方便，经济合理，具有扩建的可能性和改变运行方式时的灵活性，使其更加贴合实际，更具现实意义。
关键字：降压变电站；电气主接线；变压器；设备选型。
