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(jì)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(dāng)需要計(jì)算電費(fèi)的度數(shù)時(shí)，電度表實(shí)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(xiàng)：電流互感器在工作時(shí)，它的二次側(cè)回路始終是閉合的，不能開路，如果開路會(huì)引起高壓導(dǎo)致觸電事件，所以需要更換電流互感器時(shí)，反復(fù)檢查確保電源電路沒有電，有兩人以上看護(hù)并掛進(jìn)展合閘牌才可以進(jìn)行檢修。云南JD6000-3V采購</p><p
