燃機卡DS200TCEBG1AAB係統模塊_廈門阿米控技術有限公司

產品標題:燃機卡DS200TCEBG1AAB係統模塊備件

型號： DS200TCEBG1AAB

品牌：GE

產品詳情資料：

差分CT可以是如下圖所示的堆芯平衡。或者，差動輸入中每相兩個CT的總和將提供更大的保護區。如果使用兩個CT的總和，則觀察CT極性很重要。也可以使用如下所示的相位CT來實現求和方法。469有三個交流電壓輸入通道，每個通道都有一個隔離變壓器。電壓輸入上沒有內部保險絲或接地連接。VT比率為150.00:1。兩個VT連接為開放三角形（見圖2-10：第2-8頁的典型接線圖）或Y形（見下文）。電壓通道在內部以Y形連接，這意味著為開放式三角電壓互感器安裝B相輸入和469中性端子之間的典型接線圖三角電源連接上所示的跳線。

產品英文詳情資料：

The differential CTs may be core balance as shown in the first figure below. Alternatively, the summation of two CTs per phase into the differential input will provide a larger zone of protection. If the summation of two CTs is used, observation of CT polarity is important. The summation method may also be implemented using the phase CTs as shown below. They will have to have the same CT ratio.The 469 has three channels for AC voltage inputs, each with an isolating transformer. There are no internal fuses or ground connections on the voltage inputs. The maximum VT ratio is 150.00:1. The two VT connections are open delta (see Figure 2–10: TYPICAL WIRING DIAGRAM on page 2–8) or wye (see below). The voltage channels are connected in wye internally, which means that the jumper shown on the delta-source connection of the TYPICAL WIRING DIAGRAM, between the phase B input and the 469 neutral terminal, must be installed for open delta VTs.
