1、变电站设计说明书 1 1103510 变电站变电站设计设计 摘要 随着工业时代的不断发展，人们对电力供应的要求越来越高，特 别是供电的稳固性、可靠性和持续性。然而电网的稳固性、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。出于这几方面 的考虑，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,有二回线路；中压侧电压为 35kv,有六回出线； 其中有四回出线是双回路供电。低压侧电压为 10kv,有八回出线,其中 有六回是双回路供电。同时对于变电站内的主设备进行合理的选型。 本设计选择选择两台

2、 SFSZL-31500/110 主变压器，其他设备如站用 变，断路器，隔离开关，电流互感器，高压熔断器，电压互感器，无 功补偿装置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：关键字： 变电站变电站 设计设计 变电站设计说明书 2 Devise A 1103510 Substation student:XiaoJia-Chi supervisor:Lv-Lin Abstract With the development of the industry

3、times, people bring up higher requests to the electric power supply, especially to the stability、reliability and endurance .But the stability 、 reliability and endurance of the electrical network often rely on the transformer substations rationality and disposition. One typical transformer substatio

4、n requests the equipments in it work reliably, operate nimbly, being carried on reasonably and easy to be expended .Refer to these several reasons, in this article we devise a transformer substation for abasing voltage, which has three voltage rates: the high voltage rate is 110kV,which has two routes; the middle voltage rate is 35kv , which has six routes and four of them have double routes; the low voltage rate is 10kV, which has eight routes and six of them have doub
