被測互感器與標(biāo)準(zhǔn)互感器的二次電流差一般采用互感器校驗(yàn)儀進(jìn)行量。直接從互感器校驗(yàn)儀上讀出比值差fx(%)，相位差δx(’)。由于互感器校驗(yàn)儀測的是被測互感器與標(biāo)準(zhǔn)互感器電流差與二次電流的比值，所以對互感器校驗(yàn)儀的要求不高。要能校驗(yàn)什么等級的互感器，基本由標(biāo)準(zhǔn)互感器決定。 </p> <p> 標(biāo)準(zhǔn)互感器是互感器校驗(yàn)系統(tǒng)的關(guān)鍵**。對被測互感器進(jìn)行校驗(yàn)，除了標(biāo)準(zhǔn)互感器、互感器校驗(yàn)儀還要有給互感器提供一次電流的升流器，可以調(diào)節(jié)升流器電流的調(diào)壓器，及負(fù)載。折疊編輯本段運(yùn)行特性在電工手冊及各類教材中，對電流互感器二次開路運(yùn)行的結(jié)論是：“電流互感器二次開路產(chǎn)生幾百伏、lkV～10kV的危及人身安全的高壓；鐵芯嚴(yán)重發(fā)熱，燒壞電流互感器?！边@也是電力界公認(rèn)的法規(guī)。

我們科技服務(wù)小組在檢修學(xué)校配電盤的一只無示數(shù)電流表時發(fā)現(xiàn)，與其相串聯(lián)電流互感器二次開路運(yùn)行，實(shí)測電壓為2.6V，恢復(fù)其原閉路接法，同時在主回路串入型號、變化相同的電流互感器，二次開路長期運(yùn)行，并不發(fā)熱。這說明：目前實(shí)際應(yīng)用的電流互感器運(yùn)行特性與一百多年來傳統(tǒng)的結(jié)論相比，有著不容忽視的重大差別。上海銷售電流互感器源頭好貨上海喆和定制銷售西門子APT（原上海二工）ALH-0.66

上海喆和定制銷售西門子電流互感器。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電流互感器變換的是電流罷了。電流互感器接被測電流的繞組（匝數(shù)為N1），稱為一次繞組（或原邊繞組、初級繞組）；接測量儀表的繞組（匝數(shù)為N2）稱為二次繞組（或副邊繞組、次級繞組）。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。電流互感器在額定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。Kn=I1n/I2n電流互感器（Currenttransformer簡稱CT）的作用是可以把數(shù)值較大的一次電流通過一定的變比轉(zhuǎn)換為數(shù)值較小的二次電流，用來進(jìn)行保護(hù)、測量等用途。如變比為400/5的電流互感器，可以把實(shí)際為400A的電流轉(zhuǎn)變?yōu)?A的電流。一、電流互感器型號[3]：***字母：L—電流互感器第二字母：A—穿墻式；Z—支柱式；M—母線式；D—單匝貫穿式；V—結(jié)構(gòu)倒置式；J—零序接地檢測用；W—抗污穢；R—繞組裸露式第三字母：Z—環(huán)氧樹脂澆注式；C—瓷絕緣；Q—?dú)怏w絕緣介質(zhì)；W—與微機(jī)保護(hù)**第四字母：B—帶保護(hù)級；C—差動保護(hù)；D—D級；Q—加強(qiáng)型。

上海喆和銷售西門子電流互感器。100多年來的傳統(tǒng)結(jié)論與科技進(jìn)步、材料更新、結(jié)構(gòu)變化、工藝革新的現(xiàn)代新型電流互感器的實(shí)際二次開路電壓相比存在著巨大差別，所以傳統(tǒng)結(jié)論應(yīng)當(dāng)修正。二、電流互盛器二次開路時發(fā)熱情況分析對母線穿心式電流互感器，根據(jù)焦耳—楞次定律Q=I2Rt，二次開路時由I2=0，Q2=0，所以二次線圈不會發(fā)熱。但是，當(dāng)二次線圈由閉路轉(zhuǎn)為開路時，母線上功耗增大。對母線穿心式150／5的電流互感器一次電流為額定值時，經(jīng)過計(jì)算其功耗增量**小為9W，額定為17W。由于母線粗長，散熱忍受力好，不會發(fā)熱。所有母線穿心式電流互感器在變流實(shí)驗(yàn)臺上斷續(xù)運(yùn)行長達(dá)2年半之久，從未發(fā)現(xiàn)燒壞一例，充分體現(xiàn)了目前實(shí)用新型電流互感器發(fā)熱特性與傳統(tǒng)結(jié)論截然不同。已被平度淘汰的LQG系列電流互感器在交流實(shí)驗(yàn)臺上進(jìn)行證明，當(dāng)一次線圈電流為額定值時，二次線圈開路，保持一次電流仍為額定電流，雖然二次線圈不會發(fā)熱，但一次線圈功耗量增大。例如44號30／5的電流互感器，其一次壓降增量為2．5V，功耗增大75W，一次線圈略微發(fā)熱。上海喆和定制銷售西門子APT（原上海二工）ALH-0.66
