對每一種電流互感器，二次開路電壓隨著一次電流的變化，都有嚴(yán)格的對應(yīng)關(guān)系，*以一次額定電流時(shí)的二次開路電壓值說明。對母線穿心式150／5的電流互感器，當(dāng)穿心電流為額定值時(shí)，不同品種的電流互感器二次開路電壓為2．6～2；4V。80條二次開路電壓特性曲線的規(guī)律是：一次穿心電流從0A增至150A時(shí)，二次開路電壓開始上升幅度很大，30A以后增加甚小(即使從150A增至800A，二次開路電壓平均只上升0．2V)。 </p> <p> 母線穿心式200/5的電流互感器，二次開路電壓是3．9～6．5V；母線穿心式 300／5—2000／5的電流互感器，二次開路電壓為6．5～37．2V。 </p> <p> LQG系列從30／5—600／5的電流互感器，二次開路電壓是12．8～21．4V。 </p> <p> 變電站用的LQJ，LFC，LFCD系列50／5～300／5的電流互感器，二次開路電壓是18～121．3V。 </p> <p> 在第二次伏安特實(shí)驗(yàn)臺上，利用調(diào)壓器、電流表、導(dǎo)線將所有的電流互感器二次線圈分別接人調(diào)壓器的輸出端，當(dāng)二次輸入5A電流時(shí)，測得二次電壓和一次加額定電流時(shí)測得的二次開路電壓都有嚴(yán)格的對應(yīng)關(guān)系。若用公式計(jì)算，二次開路電壓等于二次閉路轉(zhuǎn)為開路一次電壓的增量乘以變化。從正反兩方面實(shí)驗(yàn)和法拉第電磁感應(yīng)定律推導(dǎo)結(jié)論證明了二次開路電壓測試值的真實(shí)性 </p><p style="text-indent:25px"> 上海喆和供應(yīng)西門子APT電流互感器。在供電用電的線路中電流電壓比較大的小小相差懸殊從幾安到幾萬安都有。為便于二次儀表測量需要轉(zhuǎn)換為比較統(tǒng)一的電流，另外線路上的電壓都比較高如直接測量是非常危險(xiǎn)的。電流互感器就起到變流和電氣隔離作用。較早前，顯示儀表大部分是指針式的電流電壓表，所以電流互感器的二次電流大多數(shù)是安培級的（如5A等）。現(xiàn)在的電量測量大多數(shù)字化，而計(jì)算機(jī)的采樣的信號一般為毫安級（0-5V、4-20mA等）。微型電流互感器二次電流為毫安級，主要起大互感器與采樣之間的橋梁作用。微型電流互感器也有人稱之為“儀用電流互感器”。（“儀用電流互感器”有一層含義是在實(shí)驗(yàn)室使用的多電流比精密電流互感器，一般用于擴(kuò)大儀表量程。）微型電流互感器與變壓器類似也是根據(jù)電磁感應(yīng)原理工作，變壓器變換的是電壓而微型電流互感器變換的是電流罷了。如圖繞組N1接被測電流，稱為一次繞組（或原邊繞組、初級繞組）；繞組N2接測量儀表，稱為二次繞組（或副邊繞組、次級繞組）。微型電流互感器一次繞組電流I1與二次繞組I2的電流比，叫實(shí)際電流比K。微型電流互感器在額定工作電流下工作時(shí)的電流比叫電流互感器額定電流比，用Kn表示。上海喆和定制銷售西門子APT（原上海二工）ALH-0.66

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)臺上測得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-0.66 100*85II電流互感器.上海二工電流互感器ALH-0.66
