電流互感器使用注意事項(xiàng)(1)極性連接要正確。電流互感器一般按減極性標(biāo)注，如果極性連接不正確，就會影響計(jì)量，甚至在同**路有多臺電流互感器并聯(lián)時(shí)，全造成短路***。(2)二次回路應(yīng)設(shè)保護(hù)性接地點(diǎn)，并可靠連接。為防止一、二次繞組之間絕緣擊穿后高電壓竄入低壓側(cè)危及人身和儀表安全，電流互感器二次側(cè)應(yīng)設(shè)保護(hù)性接地點(diǎn)，接地點(diǎn)只允許接一個(gè)，一般將靠近電流互感器的箱體端子接地。(3)運(yùn)行中二次繞組不允許開路。否則會導(dǎo)致以下嚴(yán)重后果：二次側(cè)出現(xiàn)高電壓，危及人身和儀表安全;出現(xiàn)過熱，可能燒壞繞組;增大計(jì)量誤差。(4)用于電能計(jì)量的電流互感器二次回路，不應(yīng)再接繼電保護(hù)裝置和自動(dòng)裝置等，以防互相影響。上海喆和定制銷售西門子APT（原上海二工）ALH-0.66

電流互感器1次側(cè)只有1到幾匝，導(dǎo)線截面積大，串入被測電路。2次側(cè)匝數(shù)多，導(dǎo)線細(xì)，與阻抗較小的儀表(電流表/功率表的電流線圈）構(gòu)成閉路。電流互感器的運(yùn)行情況相當(dāng)于2次側(cè)短路的變壓器，忽略勵(lì)磁電流，安匝數(shù)相等I1N1=I2N2電流互感器一次繞組電流I1與二次繞組I2的電流比，叫實(shí)際電流比I1/I2=N2/N1=k。勵(lì)磁電流是誤差的主要根源。測量用電流互感器的精度等級0.2/0.5/1/3,1表示變比誤差不超過±1%，另外還有0.2S和0.5S級。2、保護(hù)用電流互感器保護(hù)用電流互感器分為：1.過負(fù)荷保護(hù)電流互感器，2.差動(dòng)保護(hù)電流互感器，3.接地保護(hù)電流互感器（零序電流互感器）保護(hù)用電流互感器主要與繼電裝置配合，在線路發(fā)生短路過載等故障時(shí)，向繼電裝置提供信號切斷故障電路，以保護(hù)供電系統(tǒng)的安全。保護(hù)用電流互感器的工作條件與測量用電流保護(hù)用電流互感器互感器完全不同，保護(hù)用互感器只是在比正常電流大幾倍幾十倍的電流時(shí)才開始有效的工作。保護(hù)用互感器主要要求：1.絕緣可靠，2.足夠大的準(zhǔn)確限值系數(shù)，3.足夠的熱穩(wěn)定性和動(dòng)穩(wěn)定性。上海定制電流互感器貨期短</p><p
