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(huì)影響計(jì)量，甚至在同**路有多臺(tái)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(huì)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?，F(xiàn)貨銷售電流互感器銷售電話上海喆和定制銷售西門子APT（原上海二工）ALH-0.66

對(duì)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(cè)量上限有關(guān)，一般為額定電流的20-50%左右?？梢噪娏骰ジ衅鬟@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(duì)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。準(zhǔn)確度檢查互感器誤差試驗(yàn)一般采用被測(cè)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(cè)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(cè)互感器高出二個(gè)等級(jí)，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
