style="text-indent:25px">電流傳感器應用：感應式電流傳感器具有長期記錄，可在惡劣條件下可靠運行。因此，它們通常是安全相關，安全關鍵或高可靠性應用的自動選擇。這種應用在，航空航天，鐵路和重工業(yè)部門中很常見。這種良好聲譽的原因與基本物理和操作原理有關，它們通常**于：移動電觸點；溫度；濕度，水和冷凝；污垢，油脂，砂礫和沙子等異物。每個傳感器通常需要單獨指定和購買相關的AC生成和信號處理電路。反過來，這需要模擬電子學的重要技能和知識。由于年輕的工程師傾向于專注于數(shù)字電子，他們將傾向于采用替代的，更加數(shù)字化的方法。合肥電流傳感器批發(fā)市場電流傳感器相對稀缺的另一個原因是設計者難以指定。</p><div

style="text-indent:25px">電流傳感器使用注意事項：（1）電流傳感器必須根據(jù)被測電流的額定有效值適當選用不同的規(guī)格的產品。被測電流長時間超額，會損壞末極功放管（指磁補償式），一般情況下，2倍的過載電流持續(xù)時間不得超過1分鐘。（2）電壓傳感器必須按產品說明在原邊串入一個限流電阻R1，以使原邊得到額定電流，在一般情況下，2倍的過壓持續(xù)時間不得超過1分鐘。（3）電流電壓傳感器的比較好精度是在原邊額定值條件下得到的，所以當被測電流高于電流傳感器的額定值時，應選用相應大的傳感器；當被測電壓高于電壓傳感器的額定值時，應重新調整限流電阻。當被測電流低于額定值1/2以下時，為了得到比較好精度，可以使用多繞圈數(shù)的辦法。</p><p style="text-indent:25px">電流傳感器給大型數(shù)據(jù)中心供電的任何故障都可能給業(yè)主和客戶帶來重大的經濟損失或者災難性的后果。因此，數(shù)據(jù)中心能否可靠運營的關鍵之一是IT設備的不間斷供電。在保證不間斷供電的前提下，不斷提升不間斷供電架構的可靠性，是數(shù)據(jù)中心用戶一直以來的重要部分需求。通常數(shù)據(jù)中心不間斷供電系統(tǒng)一般包括高壓配電系統(tǒng)、變壓器、柴油發(fā)電機組、低壓配電系統(tǒng)、防雷器、UPS、電池組、列頭柜、機架分配單元（PDU）、連接器等組成環(huán)節(jié)。其中UPS作為不間斷供電系統(tǒng)的重要部分部件，起到舉足輕重的作用。電流傳感器，是一種檢測裝置，能感受到被測電流的信息。</p><div

style="text-indent:25px">電流傳感器分流器與CT不同的是，分流器不具備跨溫度或輸入電流的任何固有相移;但請記住，這并不意味著沒必要執(zhí)行相位補償。因為存在可引起電壓和電流之間非預期相移的其它相移源(如抗混疊濾波器)，所以為了在功率因數(shù)較小時確保高準確度，相位補償仍將必不可少。既然如此，這確實意味著當輸入電流或溫度改變時，可能根據(jù)所選擇的CT發(fā)生相位誤差變化。其結果是，使用電流互感器時的系統(tǒng)相位誤差會比使用分流器時的系統(tǒng)相位誤差變化大。這種較大的相位誤差變化會使簡單準確地進行相位校準變得更難，因此有可能導致跨溫度或電流測量的功率誤差發(fā)生變化。各向異性磁電阻（簡稱
