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(méi)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(xiàn)式電流互感器。沒(méi)有一次導(dǎo)體但有一次絕緣，直接套裝在母線(xiàn)上使用的一種電流互感器。折疊編輯本段校驗(yàn)方法在進(jìn)行電流互感器誤差試驗(yàn)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(jìn)，二次電流從S1出。極性檢查很簡(jiǎn)單，除了可以在互感器校驗(yàn)儀上進(jìn)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(kāi)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(xiāo)售西門(mén)子APT原廠ALH-0.66電流互感器 </p> <p> 型號(hào) ALH-0.66 30I-I 200/5ML </p> <p>
