電流互感器原理是依據(jù)電磁感應(yīng)原理的。電流互感器是由閉合的鐵心和繞組組成。它的一次側(cè)繞組匝數(shù)很少，寧夏電流變送器特性，串在需要測量的電流的線路中，因此它經(jīng)常有線路的全部電流流過，寧夏電流變送器特性，二次側(cè)繞組匝數(shù)比較多，串接在測量儀表和保護(hù)回路中，電流互感器在工作時(shí)，它的二次側(cè)回路始終是閉合的，因此測量儀表和保護(hù)回路串聯(lián)線圈的阻抗很小，電流互感器的工作狀態(tài)接近短路。電流互感器是把一次側(cè)大電流轉(zhuǎn)換成二次側(cè)小電流來使用，二次側(cè)不可開路。

把交流互感器套在被測電纜bai或者銅排上，互感器輸du出端有2個(gè)接zhi線點(diǎn)，直接接到電流變送器的輸入端，dao，這樣就OK了，但是記住，互感器不可以開路測量，要出事故的。還有，你完全沒有必要用互感器加變送器的方式去測量，直接采用穿孔式電流變送器多好，把變送器和互感器柔和到一起的 </p> <p> 測量的電流比較大，先用了一個(gè)7000/5的電流互感器，然后再用穿孔式的電流變送器對電流互感器的二次側(cè)電流進(jìn)行測量，得到的信號進(jìn)入控制器。寧夏電流變送器特性電流變送器那個(gè)品牌的好？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:
