110kV变电所电气一次部分设计

AbstractThis paper according to the task book to load and related design requirements,first proposed several main wiring scheme and the selection,choose is the mosteconomical and reliable way to the main terminal,followed by changing the designrules and related matters needing attention and the actual load to determine maintransformer units,capacity,model.Then,the maximum continuous current and short-circuit current of the bus,circuit breakers,isolation switches,voltage transformers,current transformers and other electrical equipment for selection andverification.Finally,the electrical main wiring diagram is drawn,so as to complete thedesign task of the 110kV substation.Key Words Substation,short-circuit current,equipment selection,calibration
