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的電流比叫電流互感器額定電流比，用Kn表示。上海電流互感器歡迎來電上海喆和定制銷售西門子APT（原上海二工）ALH-0.66
