35KV变电站设计

摘 要本次设计以110kV变电站为主要设计对象,分为任务书、计算书、说明书三部分,同时附有1张电气主接线图加以说明。该变电站设有2台主变压器,站内主接线分为110kV、35 kV、和10 kV三个电压等级。各个电压等级分别采用双母线、双母线、和单母分段的接线方式。
本次设计中进行了电气主接线图形式的论证、短路电流计算、主要电气设备选择及校验(包括断路器、隔离开关、电流互感器、电压互感器),同时介绍了防雷保护的配置、继电保护的规划等相关方面的知识。ABSTRACTThis design is then 110 kV transformer substations is for primarily design the objecting, and is divided into the mission book, calculation book, manual three part, at the same time fish-eye 1 electricity the lord connect the line diagram to take into the elucidation.That transformer substation establishes to have 2 main transformer of sets, stand the inside lord to connect the line to is divided into 110 kV,35 kV, with 10 three electric voltage grades of kVs.The each electric voltage grade distinguishes the adoption double the mother the line, double the mother line, divide the connecting of segment the line method with single mother.
Proceeds in this design the electricity lord connect the line sketch the types argument, short-circuit electric current calculation, main electricity equipments ( include to break the road , insulate the switch, electric current with each other , electric voltage to with each other), and introduced to defend what thunder protect to install at the same time, after the programming etc. that the electricity protect the parties concerneds knowledge.
This paper is a 35KV substation design book ,including assignment paper ,explanation paper, calculation paper and 1 graphs. The substation have 2 primary transformer including 2 voltage degree: 35KV and 10KV. Every degree adopted sectioned single bus primary connection model to supply power. In this paper, we have computed short-circuit current, designed and tested the Primary electric equipment (circuit breaker, isolation switcher, current transfer, voltage transfer, bus etc), at the same time, we also introduced prevent-thunder protection, primary protection and other knowledge relevant.
