摘要
10kV配电线路结构特点是一致性差,如有的为用户专线,只接带一、二个用户,类似于输电线路;有的呈放射状,几十台甚至上百台变压器T接于同一条线路的各个分支上;有的线路短到几百m,有的线路长到几十km;有的线路属于最末级保护,有的线路上设有开关站或有用户变电所等。
10kV distribution line structure is characterized by poor compliance. For example, sometimes the user line connects only one or two users, similar to the transmission line; some appears radial, dozens even hundreds of transformer are connected to the various branches of the same line; some short lines are only hundreds meters, and some long lines are dozens of kilometers; Some lines belong to Last-level protection, and some lines are equipped with switching station or substation.
