1、電(dian)(dian)(dian)流(liu)互(hu)(hu)感器的(de)(de)(de)接線(xian)(xian)應(ying)(ying)遵循(xun)串(chuan)聯原則：即初級繞(rao)(rao)(rao)組(zu)應(ying)(ying)與(yu)被測(ce)電(dian)(dian)(dian)路(lu)(lu)(lu)(lu)串(chuan)聯，次(ci)級繞(rao)(rao)(rao)組(zu)應(ying)(ying)與(yu)所有(you)儀表負(fu)(fu)載串(chuan)聯。2、根據被測(ce)電(dian)(dian)(dian)流(liu)，選擇合適(shi)的(de)(de)(de)變(bian)化，否則誤差會(hui)增大(da)(da)。同時，二次(ci)側一端必(bi)須接地，防止(zhi)一次(ci)側高壓(ya)一旦(dan)絕緣損壞(huai)，進入二次(ci)低(di)壓(ya)側，造成人身(shen)和(he)(he)設備事故(gu)。3、二次(ci)側不允許開(kai)(kai)(kai)路(lu)(lu)(lu)(lu)。一旦(dan)開(kai)(kai)(kai)路(lu)(lu)(lu)(lu)，原邊電(dian)(dian)(dian)流(liu)I1全部變(bian)為勵(li)磁(ci)(ci)電(dian)(dian)(dian)流(liu)，引(yin)起φm和(he)(he)E2的(de)(de)(de)突然(ran)增大(da)(da)，導(dao)致鐵芯飽和(he)(he)磁(ci)(ci)化過度，發熱嚴(yan)重(zhong)，甚至燒毀線(xian)(xian)圈;同時，磁(ci)(ci)路(lu)(lu)(lu)(lu)過飽和(he)(he)磁(ci)(ci)化后(hou)，使誤差增大(da)(da)。電(dian)(dian)(dian)流(liu)互(hu)(hu)感器正常工作時，二次(ci)側類似(si)于短(duan)(duan)路(lu)(lu)(lu)(lu)。如果突然(ran)打開(kai)(kai)(kai)，勵(li)磁(ci)(ci)電(dian)(dian)(dian)動勢會(hui)突然(ran)從小值變(bian)為大(da)(da)值，鐵芯內(nei)的(de)(de)(de)磁(ci)(ci)通會(hui)呈現嚴(yan)重(zhong)飽和(he)(he)的(de)(de)(de)平(ping)頂。因此(ci)，當磁(ci)(ci)通過零時，次(ci)級繞(rao)(rao)(rao)組(zu)會(hui)感應(ying)(ying)出非常高的(de)(de)(de)峰值波。此(ci)外，一次(ci)側開(kai)(kai)(kai)路(lu)(lu)(lu)(lu)導(dao)致二次(ci)側電(dian)(dian)(dian)壓(ya)達(da)到數百伏，觸摸會(hui)引(yin)起電(dian)(dian)(dian)擊。因此(ci)，電(dian)(dian)(dian)流(liu)互(hu)(hu)感器二次(ci)側裝有(you)短(duan)(duan)路(lu)(lu)(lu)(lu)開(kai)(kai)(kai)關，防止(zhi)一次(ci)側開(kai)(kai)(kai)路(lu)(lu)(lu)(lu)。使用(yong)(yong)過程中(zhong)，一旦(dan)二次(ci)側開(kai)(kai)(kai)路(lu)(lu)(lu)(lu)，應(ying)(ying)立即解除電(dian)(dian)(dian)路(lu)(lu)(lu)(lu)負(fu)(fu)載，然(ran)后(hou)停止(zhi)加工。處理完所有(you)內(nei)容后(hou)可(ke)以重(zhong)復使用(yong)(yong)。4、為滿足測(ce)量(liang)儀表、繼電(dian)(dian)(dian)保(bao)護、斷(duan)路(lu)(lu)(lu)(lu)器故(gu)障(zhang)判斷(duan)和(he)(he)故(gu)障(zhang)濾波等(deng)需要(yao)，發電(dian)(dian)(dian)機(ji)、變(bian)壓(ya)器、插座、母(mu)線(xian)(xian)段斷(duan)路(lu)(lu)(lu)(lu)器、母(mu)線(xian)(xian)斷(duan)路(lu)(lu)(lu)(lu)器、旁(pang)路(lu)(lu)(lu)(lu)斷(duan)路(lu)(lu)(lu)(lu)器等(deng)電(dian)(dian)(dian)路(lu)(lu)(lu)(lu)均采用(yong)(yong)設置2～8個次(ci)級繞(rao)(rao)(rao)組(zu)電(dian)(dian)(dian)流(liu)互(hu)(hu)感器。對于大(da)(da)電(dian)(dian)(dian)流(liu)接地系統，一般采用(yong)(yong)三相(xiang)配置;用(yong)(yong)于小電(dian)(dian)(dian)流(liu)接地系統。浙(zhe)江邦(bang)凱(kai)電(dian)(dian)(dian)氣科技有(you)限公司是一家專(zhuan)業提供互(hu)(hu)感器的(de)(de)(de)公司，歡(huan)迎新(xin)老客戶來電(dian)(dian)(dian)！天(tian)津低(di)壓(ya)互(hu)(hu)感器要(yao)多少錢
