當(dāng)一次電流為0A時(shí)，二次輸出電壓波形為一條水平線。隨著一次電流的增大，56種電流互感器波形變化十分復(fù)雜，又各具有其自身特色。如6號(hào)互感器，一次電流為3A，二次電壓波形為正弦波，一次電流從4A增至150A波形畸變，隨著一次電流增**形畸變加劇，其變化特別是有效寬度變窄，峰—峰值上升，占空因數(shù)下降，但每半周包圍的面積增加甚微。 </p> <p> 比差特性分析 </p> <p> 目前，我國(guó)計(jì)量電流時(shí)，要求用1．5mm2的銅線將電流互感器二次線圈和電度表電流線圈短接，這是降低精度產(chǎn)生正比差的應(yīng)用方法。以母線穿心式150／5的電流互感器為例，我們分別以1．5mm2長(zhǎng)4m的銅線，將其二次線圈分別與150／5A的電流表和電度表的電流線圈串聯(lián)時(shí)，當(dāng)一次穿心電流為150A時(shí)，所有電流互感器都能使電流表碰針，若一次電流降至135A，電流表示數(shù)為140～150A。 </p> <p> 在變流實(shí)驗(yàn)臺(tái)上測(cè)得8000個(gè)數(shù)據(jù)表明，當(dāng)一次電流超過額定值10％，隨著一次電流增大，正比差越來越明顯，而一次電流為15A以下時(shí)，電流互感器二次測(cè)中的電流表示數(shù)有負(fù)比差。上海喆和定制銷售西門子APT（原上海二工）ALH-0.66

消除誤差的方法兩年內(nèi)我們探索了導(dǎo)線、分?jǐn)?shù)匝、電容、電感、電阻絲等對(duì)正比差補(bǔ)償方法。1995年底，我們終于找到了可使電流互感器正、負(fù)比差都明顯減小的技術(shù)方案。例如23號(hào)200／5的電流互感器，當(dāng)母線穿心一匝，一次電流為180A時(shí)，二次顯示194A，正比差為14A，一次電流為5A，二次示數(shù)為0A，負(fù)比差為5A。利用這種技術(shù)方案，可以使該電流互感器一次電流從0A到額定電流的整個(gè)區(qū)間，正比差為0A，負(fù)比差額定值為lA，從而發(fā)現(xiàn)了降低電流互感器比差的技術(shù)方案。電流互感器的負(fù)載特性當(dāng)二次測(cè)所接負(fù)載阻抗遠(yuǎn)大于銘牌上標(biāo)定的阻抗時(shí)，電流互感器是一恒壓源。例如9號(hào)150／5互感器，銘牌上標(biāo)定的阻抗為0．2Ω。當(dāng)一次電流為150A，二次開路時(shí)，用MFl73型萬用表交流10V檔，精度為9kΩ／V，相當(dāng)于在二次回路上串聯(lián)90kΩ的電阻，測(cè)得其電壓為2．6V；當(dāng)二次測(cè)并接15Ω300磁場(chǎng)變阻器，分別取阻值15Ω、7．5Ω、3．75Ω時(shí)，二次電壓仍為2．6V；當(dāng)取1．875Ω時(shí)二次電壓才降為2．55V，有力地證明了上述結(jié)論。當(dāng)外阻遠(yuǎn)小于標(biāo)定阻抗時(shí)，電流互感器接近一恒流源。例如9號(hào)150／5互感器，將一次電流調(diào)至135A。上海喆和定制銷售西門子APT（原上海二工）ALH-0.66
