電量變送器的原理電量變送器是一種將被測電量(交流電壓、電流、有功功率、無功功率、有功電能、無功電能、頻率、相位、功率因數(shù)、直流電壓、電流等)轉(zhuǎn)換成按線性比例直流電流或電壓輸出(電能脈沖輸出)的測量儀表。 </p> <p> 它**應(yīng)用于電力、石油、煤炭、冶金、鐵道、市政等部門的電氣測量、自動控制以及調(diào)度系統(tǒng)。電量變送器的基本測量電路一般由下圖幾個部分組成：由于我們需要測量的電量一般都為高電壓(57.7-380V)和大電流(1A-10A)，如果不對它們進(jìn)行隔離和把幅度減小，將對人身安全和設(shè)備造成嚴(yán)重威脅，信號輸入隔離一般采用電壓互感器(PT)和電流互感器(CT)，對這一部分的基本要求為： </p> <p> a. 信號隔離的耐壓絕緣性能要好，耐壓應(yīng)>2kV。 </p> <p> b. 線性要好，由于PT、CT都采用鐵磁材料加工而成，它們的線性不好，在以后的電路中是很難補償?shù)?，因此，一定要選用質(zhì)量材料和先進(jìn)工藝制造的高線性度PT、CT，才能保證變送器測量的線性度。 </p> <p> <br />

兩線制電流變送器，“兩線制”指的是其現(xiàn)場的電流變送器與其控制室的控制儀器之間*用兩根線來實現(xiàn)連接，這兩根線一根是電源線，一根是信號線(三線制電流變送器較兩線制多一根信號線，四線制電流變送器較三線制多一根電源線)。兩線制電流變送器線路少，不*可節(jié)省電纜線，還不易受到熱電偶、電阻壓降、溫漂等的影響;且其兩線的輸出口處易設(shè)防雷器件，可有效地防止雷爆等現(xiàn)象的發(fā)生。 </p><p> 電流變送器計算電流的方法 100已知：U=380V P=45KW ，電流互感器變比為150/5，電流變送器輸出12mA </p> <p> <p> 你的電流互感bai器的變比是150：5，輸出信號給du電流變送zhi器，電流變送器的輸出信號應(yīng)該是daoDC 4-20mA </p> <p> 電流變送器0-5A，對應(yīng)輸出是DC4-20mA，當(dāng)電流為0時，輸出信號是4mA，當(dāng)電流為5A時，輸出信號是20mA，電流為增加1A，輸出信號就是（4mA+3.2mA），電流為2A時，輸出信號就是（4mA+3.2*2mA），以此類推，輸出是線性的，所以12mA，對應(yīng)的實際電流應(yīng)該是2.5A </p> <p> 電流互感器的變比是150：5，實際輸出電流是2.5A，則電機(jī)的實際運行電流是75A </p> <p> <br /> </p> 三相直流電流變送器接線圖？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="安徽電流變送器電源,電流變送器"

電流變送器根據(jù)電流形式的不同可分為直流電流變送器和交流電流變送器兩種，其中交流電流變送器根據(jù)其結(jié)構(gòu)形式的不同又可分為單路交流電流變送器和三路交流電路變送器，根據(jù)其輸出接線方式的不同可分為兩線制電流變送器和三線制電流變送器。 </p> <p> 流變送器具有精度高，體積小、功耗小、頻響寬、抗干擾等特性。國內(nèi)**4種補償措施和6大***保護(hù)功能，兩線端口防感應(yīng)雷能力強，具有雷擊波和突波的保護(hù)能力等優(yōu)點。特別適用發(fā)電機(jī)、電動機(jī)、智能低壓配電柜、空調(diào)、風(fēng)機(jī)、路燈等負(fù)載電流的智能監(jiān)控系統(tǒng)。電流變送器**功耗，單只靜態(tài)時0.096W，滿量程功耗為0.48W，輸出電流內(nèi)部限制功耗為0.6W。
