兩者的使用發(fā)展方向由于電磁式電流互感器存在的易飽和、非線性及頻帶窄等問題，電子式電流互感器逐漸興起。電子式電流互感器一般具有抗磁飽和、低功耗、寬頻帶等優(yōu)點。國內(nèi)具有代表性的電子式互感器有AnyWay變頻電壓傳感器、AnyWay變頻電流傳感器和變頻功率傳感器，其中，AnyWay變頻功率傳感器屬于電壓、電流組合式互感器。該互感器的主要特點如下1、采用前端數(shù)字化技術(shù)，光纖傳輸，電磁兼容性好。2、幅頻特性和相頻特性好，在寬幅值、頻率、相位范圍內(nèi)均可獲得較高的測量精度。3、屬于數(shù)字式傳感器，二次儀表不會引入誤差，傳感器誤差就是系統(tǒng)誤差。 </p> <p> 額定電壓電流互感器額定電壓應大于裝設(shè)點線路額定電壓 [7] 。變比應根據(jù)一次負荷計算電流IC選擇電流互感器變比。電流互感器一次側(cè)額定電流標準比（如20、30、40、50、75、100、150、2×a/C）等多種規(guī)格，二次側(cè)額定電流通常為1A或5A。其中2×a/C表示同一臺產(chǎn)品有兩種電流比，通過改變產(chǎn)品的連接片接線方式實現(xiàn)，當串聯(lián)時，電流比為a/c，并聯(lián)時電流比為2×a/C。一般情況下，計量用電流互感器變流比的選擇應使其一次額定電流I1n不小于線路中的負荷電流（即計算IC）。如線路中負荷計算電流為350A，則電流互感器的變流比應選擇400/5 </p><p style="text-indent:25px">對于保護用電流互感器的裝設(shè)地點應按盡量消除主保護裝置的不保護區(qū)來設(shè)置。例如：若有兩組電流互感器，且位置允許時，應設(shè)在斷路器兩側(cè)，使斷路器處于交叉保護范圍之中6）為了防止支柱式電流互感器套管閃絡(luò)造成母線故障，電流互感器通常布置在斷路器的出線或變壓器側(cè)7）為了減輕發(fā)電機內(nèi)部故障時的損傷，用于自動調(diào)節(jié)勵磁裝置的電流互感器應布置在發(fā)電機定子繞組的出線側(cè)。為了便于分析和在發(fā)電機并入系統(tǒng)前發(fā)現(xiàn)內(nèi)部故障，用于測量儀表的電流互感器宜裝在發(fā)電機中性點側(cè)。接線方式電流互感器的接線方式按其所接負載的運行要求確定。**常用的接線方式為單相、三相星形和不完全星形三種，分別如圖4a、圖4b和圖4c。電流互感器接線方式額定變比和誤差：電流互感器的額定變比KN指電流互感器的額定電流比。即：KN=I1N/I2N電流互感器原邊電流在一定范圍內(nèi)變動時，一般規(guī)定為10～120%I1N，副邊電流應按比例變化，而且原、副邊電壓（或電流）應該同相位。但由于互感器存在內(nèi)阻抗、勵磁電流和損耗等因素而使比值及相位出現(xiàn)誤差，分別稱為比差和角差。比差為經(jīng)折算后的二次電流與一次電流量值大小之差對后者之比，即fI 為電流互感器的比差。當KNI2>I1時，比差為正，反之為負。上海喆和定制銷售西門子APT（原上海二工）ALH-0.66 80I電流互感器.</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="上海實力特賣電流互感器多少錢,電流互感器"

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，用來進行保護、測量等用途。如變比為400/5的電流互感器，可以把實際為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—氣體絕緣介質(zhì)；W—與微機保護**第四字母：B—帶保護級；C—差動保護；D—D級；Q—加強型。上海喆和定制銷售西門子APT（原上海二工）ALH-0.66
