對于沒有采取補(bǔ)償措施的電流互感器，比差為負(fù)值，角差為正值，比差的***值和角差均隨電流增大而減小。采用補(bǔ)償?shù)霓k法可以減小互感器的誤差。一般通過在互感器上加繞附加繞組或增添附加鐵心，以及接入相應(yīng)的電阻、電感、電容元件來補(bǔ)償。常用的補(bǔ)償法有匝數(shù)補(bǔ)償、分?jǐn)?shù)匝補(bǔ)償、小鐵心補(bǔ)償、并聯(lián)電容補(bǔ)償?shù)取Ｐｒ?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試驗(yàn)。極性檢查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。退磁檢查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。長期使用后的互感器都應(yīng)該退磁。互感器檢驗(yàn)前也要退磁。退磁就是通過一次或二次繞組以交變的勵磁電流，給鐵芯以交變的磁場。從0開始逐漸加大交變的磁場(勵磁電流)使鐵芯達(dá)到飽和狀態(tài)，然后再慢慢減小勵磁電流到零，以消除剩磁。上海銷售西門子電流互感器哪家專業(yè)上海喆和定制銷售西門子APT（原上海二工）ALH-0.66

上海喆和銷售電流互感器。對于電流互感器退磁，一次繞組開路，二次繞組通以工頻電流，從零開始逐漸增加到一定的電流值(該電流值與互感器的設(shè)計(jì)測量上限有關(guān)，一般為額定電流的20-50%左右?？梢赃@樣判斷，如果電流突然急劇變大，此時(shí)表示鐵芯以進(jìn)入磁飽和階段)。然后再將電流緩慢降為零，如此重復(fù)2-3次。在斷開電源前，應(yīng)將一次繞組短接，才斷開電源。鐵芯退磁完成。此方法稱開路退磁法。對于有些電流互感器，由于二次繞組的匝數(shù)都比較多。若采用開路退磁法，開路的繞組可能產(chǎn)生高電壓。因此可以在二次繞組接上較大的電阻(額定阻抗的10-20倍)。一次繞組通以電流，從零漸變到互感器一次繞組的允許的額定電流，再漸變到零，如此重復(fù)2-3次。由于接有負(fù)載鐵芯可能不能完全退磁。由于一次繞組的額定電流有限制，過大的話可能燒壞一次繞組。如果接有負(fù)載的二次繞組產(chǎn)生電壓不是過高的話，可以加大二次繞組的負(fù)載電阻。這樣可以提高退磁效果。3、電流互感器誤差試驗(yàn)互感器誤差試驗(yàn)一般采用被測互感器與標(biāo)準(zhǔn)互感器進(jìn)行比較，兩互感器的二次電流差即為被測互感器誤差。此種檢驗(yàn)方法稱比較法。標(biāo)準(zhǔn)互感器要求比被測互感器高出二個(gè)等級，此時(shí)標(biāo)準(zhǔn)互感器誤差可忽略不計(jì)。上海喆和定制銷售西門子APT（原上海二工）ALH-0.66
