產品介紹
T2100 勵(li)磁(ci)損(sun)(sun)耗繼電(dian)(dian)(dian)(dian)器(qi)可(ke)防止同步發電(dian)(dian)(dian)(dian)機出現部分或(huo)完全勵(li)磁(ci)損(sun)(sun)耗（勵(li)磁(ci)損(sun)(sun)耗）。如(ru)果(guo)并聯(lian)運行(xing)的(de)(de)發電(dian)(dian)(dian)(dian)機具(ju)有低勵(li)磁(ci)，則高感應電(dian)(dian)(dian)(dian)流(liu)流(liu)入發電(dian)(dian)(dian)(dian)機。該(gai)電(dian)(dian)(dian)(dian)流(liu)被檢測(ce)到，故(gu)障發電(dian)(dian)(dian)(dian)機的(de)(de)斷路器(qi)跳閘(zha)，從而(er)(er)避免其他發電(dian)(dian)(dian)(dian)機過(guo)載(zai)而(er)(er)系統(tong)可(ke)能停電(dian)(dian)(dian)(dian)。T2100 測(ce)量通(tong)過(guo)連(lian)接在(zai) L1 相上的(de)(de)外部 5A CT 的(de)(de)電(dian)(dian)(dian)(dian)流(liu)。相位角 (phi) 由 L1 和 L2 上的(de)(de)電(dian)(dian)(dian)(dian)壓測(ce)量值確定。T2100 將(jiang)(jiang)無功電(dian)(dian)(dian)(dian)流(liu)計(ji)算為 I x sin phi。如(ru)果(guo)無功電(dian)(dian)(dian)(dian)流(liu)變為負值并超過(guo)預(yu)設水平 (0.5 – 1.4 x I)，則啟動 LED 將(jiang)(jiang)點亮(liang)并且跳閘(zha)延遲(chi)計(ji)時器(qi)（3 – 30 秒(miao)）將(jiang)(jiang)激活。內置(zhi)跳閘(zha)繼電(dian)(dian)(dian)(dian)器(qi)將(jiang)(jiang)在(zai)延遲(chi)結(jie)束(shu)后通(tong)電(dian)(dian)(dian)(dian)，前提是在(zai)延遲(chi)時間(jian)內持續超過(guo)預(yu)設跳閘(zha)水平。
