電磁式電流互感器。根據(jù)電磁感應(yīng)原理實現(xiàn)電流變換的電流互感器。 </p> <p> 光電式電流互感器。通過光電變換原理以實現(xiàn)電流變換的電流互感器，目前還在研制中。 </p> <p> 按安裝方式分 </p> <p> 貫穿式電流互感器。用來穿過屏板或墻壁的電流互感器。 </p> <p> 支柱式電流互感器。安裝在平面或支柱上，兼做一次電路導(dǎo)體支柱用的電流互感器。 </p> <p> 套管式電流互感器。沒有一次導(dǎo)體和一次絕緣，直接套裝在絕緣的套管上的一種電流互感器。 </p> <p> 母線式電流互感器。沒有一次導(dǎo)體但有一次絕緣，直接套裝在母線上使用的一種電流互感器。折疊編輯本段校驗方法在進行電流互感器誤差試驗之前,通常需要檢查極性和退磁等主面特性。 </p> <p> 1、電流互感器極性檢查： </p> <p> 電流互感器一次繞組標(biāo)志為P1、P2，二次繞組標(biāo)志為S1、S2。若P1、S1是同名端，則這種標(biāo)志叫減極性。一次電流從P1進，二次電流從S1出。極性檢查很簡單，除了可以在互感器校驗儀上進行檢查外，還可以使用直流檢查法。 </p> <p> 2、電流互感器退磁檢查 </p> <p> 電流互感器在電流突然下降的情況下，互感器鐵芯可能產(chǎn)生剩磁。如電流互感器在大電流情況下突然切斷電源、二次繞組突然開路等?；ジ衅麒F芯有剩磁，使鐵芯磁導(dǎo)率下降，影響互感器性能。 </p><p> 上海喆和銷售西門子APT原廠ALH-0.66電流互感器 </p> <p> 型號 ALH-0.66 60I 500/1 0.2R 5V </p> <p> 型號 ALH-0.66 D22

準(zhǔn)確級選擇的原則：計費計量用的電流互感器其準(zhǔn)確級不低于0．5級；用于監(jiān)視各進出線回路中負(fù)荷電流大小的電流表應(yīng)選用1．0—3．0級電流互感器。為了保證準(zhǔn)確度誤差不超過規(guī)定值，一般還校驗電流互感器二次負(fù)荷（伏安），互感器二次負(fù)荷S2不大于額定負(fù)荷S2n，所選準(zhǔn)確度才能得到保證。準(zhǔn)確度校驗公式：S2≤S2n。二次回路的負(fù)荷l：取決于二次回路的阻抗Z2的值，則：S2=I2n2︱Z2︱≈I2n2（∑︱Zi︱+ RWl+RXC）或S2V1≈∑Si+I2n2（RWl+RXC）式中，Si、Zi為二次回路中的儀表、繼電器線圈的額定負(fù)荷和阻抗，RXC為二次回路中所有接頭、觸點的接觸電阻，一般取0．1Ω，RWL為二次回路導(dǎo)線電阻，計算公式化為：RWL=LC/（r×S）。式中，r為導(dǎo)線的導(dǎo)電率，銅線r=53m/（Ωmm2），鋁線r=32m（Ωmm2），S為導(dǎo)線截面積（mm2），LC為導(dǎo)線的計算長度（m）。設(shè)互感器到儀表單向長度為L1，則：L1互感器為星形接LC=L1兩相V形接線2L1一相式接線繼電保護用的電流互感器的準(zhǔn)確度常用的有5P和l0P。保護級的準(zhǔn)確度是以額定準(zhǔn)確限值一次電流下的電流互感器額定復(fù)合誤差ε%來標(biāo)稱的（如5P對應(yīng)的ε%=5%）。上海銷售電流互感器好價格</p><p
