文档介绍：110-35-10变电站设计
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。

Abstract
With the development of the industry 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 work often rely on the transformer substation’s rationality and disposition. One typical transformer substation 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 double routes. In the same time ,we select the main equipments for the transformer substation .This article select two main transformer (SFSZL-31500/110) and other equipments, for example : transformer used for substation ,breaker , isolator ,current transformer, voltage transformer, high voltage fuse ,
Idle pensator ,the protecting equipments and so on are also selected ,devised and disposed according to the actual fact. What’s more, we try our best to mange to make the substation work reliably, operate nimbly, be carried on reasonably and easy to be expended. So that it can close the fact more.
