西門子APT電流互感器上海喆和供，電流互感器原理是依據(jù)電磁感應(yīng)原理的。電流互感器是由閉合的鐵心和繞組組成。它的一次側(cè)繞組匝數(shù)很少，串在需要測量的電流的線路中，因此它經(jīng)常有線路的全部電流流過，二次側(cè)繞組匝數(shù)比較多，串接在測量儀表和保護回路中，電流互感器在工作時，它的二次側(cè)回路始終是閉合的，因此測量儀表和保護回路串聯(lián)線圈的阻抗很小，電流互感器的工作狀態(tài)接近短路。電流互感器是把一次側(cè)大電流轉(zhuǎn)換成二次側(cè)小電流來使用，二次側(cè)不可開路。 </p> <p> 西門子APT電流互感器上海喆和供電流互感器是由閉合的鐵心和繞組組成。它的一次繞組匝數(shù)很少，串在需要測量的電流的線路中，因此它經(jīng)常有線路的全部電流流過，二次繞組匝數(shù)比較多，串接在測量儀表和保護回路中，電流互感器在工作時，它的2次回路始終是閉合的，因此測量儀表和保護回路串聯(lián)線圈的阻抗很小，電流互感器的工作狀態(tài)接近短路。 </p> <p> 西門子APT電流互感器上海喆和供電流互感器的作用是可以把數(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。 </p><p> 上海喆和供應(yīng)西門子APT電流互感器ALH-0.66 </p> <p> 消除誤差的方法兩年內(nèi)我們探索了導線、分數(shù)匝、電容、電感、電阻絲等對正比差補償方法。1995年底，我們終于找到了可使電流互感器正、負比差都明顯減小的技術(shù)方案。例如23號200／5的電流互感器，當母線穿心一匝，一次電流為180A時，二次顯示194A，正比差為14A，一次電流為5A，二次示數(shù)為0A，負比差為5A。利用這種技術(shù)方案，可以使該電流互感器一次電流從0A到額定電流的整個區(qū)間，正比差為0A，負比差額定值為lA，從而發(fā)現(xiàn)了降低電流互感器比差的技術(shù)方案。電流互感器的負載特性當二次測所接負載阻抗遠大于銘牌上標定的阻抗時，電流互感器是一恒壓源。例如9號150／5互感器，銘牌上標定的阻抗為0．2Ω。當一次電流為150A，二次開路時，用MFl73型萬用表交流10V檔，精度為9kΩ／V，相當于在二次回路上串聯(lián)90kΩ的電阻，測得其電壓為2．6V；當二次測并接15Ω300磁場變阻器，分別取阻值15Ω、7．5Ω、3．75Ω時，二次電壓仍為2．6V；當取1．875Ω時二次電壓才降為2．55V，有力地證明了上述結(jié)論。當外阻遠小于標定阻抗時，電流互感器接近一恒流源。例如9號150／5互感器，將一次電流調(diào)至135A。上海喆和定制銷售西門子APT（原上海二工）ALH-0.66

style="text-indent:25px">對于保護用電流互感器的裝設(shè)地點應(yīng)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(yīng)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(yīng)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(yīng)按比例變化，而且原、副邊電壓（或電流）應(yīng)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 120III電流互感器.上海上海二工電流互感器量大從優(yōu)</p><p style="text-indent:25px">上海喆和定制銷售西門子APT（原上海二工）ALH-0.66 180II電流互感器.上海優(yōu)惠特賣電流互感器好價格</p><p>
