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(cè)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(cè)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(jí)的（如5A等）?，F(xiàn)在的電量測(cè)量大多數(shù)字化，而計(jì)算機(jī)的采樣的信號(hào)一般為毫安級(jí)（0-5V、4-20mA等）。微型電流互感器二次電流為毫安級(jí)，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，上海廠家授權(quán)銷售電流互感器源頭直供，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(cè)電流，稱為一次繞組（或原邊繞組、初級(jí)繞組）；繞組N2接測(cè)量?jī)x表，稱為二次繞組（或副邊繞組、次級(jí)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，上海廠家授權(quán)銷售電流互感器源頭直供，用Kn表示，上海廠家授權(quán)銷售電流互感器源頭直供。上海喆和定制銷售西門子APT（原上海二工）ALH-0.66

是依據(jù)電磁感應(yīng)原理的。電流互感器是由閉合的鐵心和繞組組成。它的一次繞組匝數(shù)很少，串在需要測(cè)量的電流的線路中，因此它經(jīng)常有線路的全部電流流過，二次繞組匝數(shù)比較多，串接在測(cè)量?jī)x表和保護(hù)回路中，電流互感器在工作時(shí)，它的二次回路始終是閉合的，因此測(cè)量?jī)x表和保護(hù)回路串聯(lián)線圈的阻抗很小，電流互感器的工作狀態(tài)接近短路。 </p> <p> 在發(fā)電、變電、輸電、配電和用電的線路中電流大小懸殊，從幾安到幾萬安都有。為便于測(cè)量、保護(hù)和控制需要轉(zhuǎn)換為比較統(tǒng)一的電流，另外線路上的電壓一般都比較高如直接測(cè)量是非常危險(xiǎn)的。電流互感器就起到電流變換和電氣隔離作用 [1] 。對(duì)于指針式的電流表，電流互感器的二次電流大多數(shù)是安培級(jí)的（如5A等）。對(duì)于數(shù)字化儀表，采樣的信號(hào)一般為毫安級(jí)（0-5V、4-20mA等）。微型電流互感器二次電流為毫安級(jí)，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。）上海實(shí)力特賣電流互感器貨源充足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。
