变电站是电力系统的重要组成部分,电气主接线是发电厂变电所的主要环节.本次设计为220kV变电站初步设计,分为主接线、短路电流计算、设备选择等三部分,所设计的内容力求概念清楚,层次分明.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220kV 、110kV、和35kV三个电压等级.各个电压等级分别采用双母线、单母分段、和单母分段的接线方式.本文从主接线、短路电流的计算、设备选择和保护等几方面对变电站设计进行了阐述

Answer 1

The transformer substation is the important constituent of the electrical power system ,the electrical host wiring is the key link of power plant transformer substation .This design is preliminary design of the 220kV transformer substation ,divides into the host wiring,the short-circuit current computation,the equipment choice etc.three parts,the designs content endeavour clear concept,each level clearly demarcate.Attaches 1 electrical host wiring diagram to explain.This transformer substation is equipped with 2 main transformers,in the station the host wiring divides into 220kV,110kV,and the 35kV three voltage ranks.Each voltage rank uses the double generatrix,the single mother separately partitions the wiring way which,and the single mother partitions.This article from the host wiring,the short-circuit current computation,the equipment choice and the protection and so on several aspects has carried on the elaboration to the transformer substation design.
