上海喆和供應(yīng)西門(mén)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(wàn)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，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，用Kn表示。上海喆和定制銷售西門(mén)子APT（原上海二工）ALH-0.66
