Ib ammeter shunt yog ib qho kev sib txuas qis heev ntawm ob lub ntsiab lus hauv ib qho hluav taws xob hluav taws xob uas tsim txoj hauv kev rau ib feem ntawm qhov tam sim no. Shunt voltage poob yog siv ua ke nrog ib qho ammeter ntsuas amperage ntawm Circuit Court.

Ntawm no, lub shunt amp meter ua haujlwm li cas?

Ib ammeter shunt tso cai rau kev ntsuas ntawm cov nqi tam sim no loj dhau los ntsuas ncaj qha los ntawm ib qho tshwj xeeb ammeter . Hauv qhov no, cais shunt , ib tug resistor ntawm tsawg heev tab sis paub tseeb tsis kam, yog muab tso rau nyob rau hauv parallel nrog ib tug voltmeter, yog li ntawd tag nrho cov tam sim no yuav tsum tau ntsuas yuav ntws los ntawm lub voltmeter. shunt.

Ib yam li ntawd, koj siv lub shunt tam sim no li cas? Ah, ok - qhov ntawd ua rau kev nkag siab ntau dua tam sim no! A tam sim no shunt tsuas yog tus nqi qis resistor, ua los lis ntau tam sim no . Koj tso ib tam sim no los ntawm nws, thiab tom qab ntawd ntsuas qhov voltage hla nws, thiab siv Ohm txoj cai los txheeb xyuas qhov tam sim no . 10A / 75 mV shunt txhais tau tias nws ntsuas 75 mV thaum 10A tab tom hla nws.

Ib yam li ntawd, koj tuaj yeem nug, shunt yog dab tsi thiab nws siv?

Shunt yog ib qho khoom siv uas tso cai rau hluav taws xob tam sim no hla mus rau lwm qhov chaw hauv Circuit Court los ntawm kev tsim txoj hauv kev tsis tshua muaj zog. A shunt (aka tam sim no shunt resistor los yog ammeter shunt ) yog lub siab precision resistor uas tuaj yeem siv los ntsuas qhov tam sim no ntws los ntawm lub voj voog.

Yuav ua li cas koj xam shunt?

Yuav ua li cas xam ib Shunt

  1. Sau rau Ohm txoj cai qhia ntawm "V = I * R" qhov "V" yog qhov hluav taws xob poob hla shunt resistor, "I" yog qhov tam sim no ntws los ntawm shunt thiab "R" yog qhov shunt tsis kam.
  2. Hloov tus nqi ntawm qhov voltage "V" thiab tam sim no "I" hauv Ohm txoj cai qhia.
