style="text-indent:25px">一般我們都知道是用于測量大電流能把它轉(zhuǎn)換為0-5A左右的小電流，然后接入到電流表或者電度表等。1.2CT變比計算比如線路工作電路為450A左右，那么我們可以選0.5級的500/5A的電流互感器。然后按需接到電流表或者電度表中。他的變比為500/5=100，當需要計算電費的度數(shù)時，電度表實際測量的度數(shù)需*100倍才是真正用了多少度電哦。1.3電流互感器CT接線如圖2注意事項：電流互感器在工作時，它的二次側(cè)回路始終是閉合的，不能開路，如果開路會引起高壓導(dǎo)致觸電事件，所以需要更換電流互感器時，反復(fù)檢查確保電源電路沒有電，有兩人以上看護并掛進展合閘牌才可以進行檢修。</p><p> 兩線制電流變送器（下） </p> <p> 3、電容性干擾會導(dǎo)致接收器電阻有關(guān)誤差，對于4～20mA兩線制環(huán)路，接收器電阻通常為250Ω（取樣Uout=1～5V）這個電阻小到不足以產(chǎn)生明顯誤差，因此，可以允許的電線長度比電壓遙測系統(tǒng)更長更遠； </p> <p> 4、各個單臺示讀裝置或記錄裝置可以在電線長度不等的不同通道間進行換接，不因電線長度的不等而造成精度的差異，實現(xiàn)分散采集，分散式采集的好處就是：分散采集，集中控制.... </p> <p> 5、將4mA用于零電平，使判斷開路與短路或傳感器損壞（0mA狀態(tài)）十分方便。 </p> <p> 6,在兩線輸出口非常容易增設(shè)一兩只防雷防浪涌器件,有利于安全防雷防爆。
