摘　　要：扩大内桥接线的运行方式有9种,对备用电源自动投入(简称备自投)的逻辑需求多达数十种,而目前应用的备自投装置只适用其中的4种运行方式,且每种运行方式只能有一种动作逻辑,有很大的局限性。文中介绍的扩大内桥备自投装置能很好地解决这些问题,该装置将所有逻辑需求融合成一个基本的备自投逻辑,实现简单,适应性强。在某110kV变电站的整组试验和试运行情况表明,该装置能完全适应扩大内桥接线不同运行方式下不同的逻辑需求。There are 9 operating modes for expanded inter-bridge connection and as many as several dozen logics for backup power automatic throw-in. At present only 4 operating modes have been put into operation and each mode adopts only one control logic, so that its application is limited. A novel adaptive backup power automatic throw-in device for expanded inter-bridge has been developed and introduced. All of logic relationships have been summarized and extracted to form one adaptive fundamental control logic, which can be implemented simply and adapted to different operating modes. The experiments and test operation results in a 110 kV substation prove that the device can satisfy different control logics of different operating modes with expanded inner-bridge.
