基于新型智能环网柜的V-I-T型自动重合器方案

The Plan of V-I-T Type Automatic Coincide Machine for New Type Intellectual Circle Cabinet

V-I-T型自动重合器方案适用于环网或辐射线路,环网柜进线采用断路器,出线采用负荷开关或断路器,环网柜之间采用FTU智能自动化功能配合,无需通信网络,自动完成故障定位、清除、隔离和转供,调试、维护简单方便,不用变电站出口跳闸,大大减少停电面积和停电时间。

The V - I - T automatic recloser scheme is applicable to loop or radialized networks, in which switchgears are applied with breakers on incoming lines and load switches on outcoming lines. Intelligent automatic cooperation functions are applied between switchgears, which can complete fault location, clear, isolation and load transfer automatically without communication. The whole procedure will not cause breaker trip in substation. System with V - I - T scheme is maintained simply, and the scope and the time of power interruption are decreased greatly.
