Txoj kev suav ntawm ammeter ntau ntau tom qab siv shunt
Rau kev ntsuas lub cev muaj zog, feem ntau lub ammeter yuav tsum tau nruab nrog ntau lub shunts los daws qhov teeb meem ntawm kev ua kom ntseeg tau qhov kev ntsuas qhov tseeb ntawm qhov ntsuas loj. Lub sijhawm no, nws yuav tsum tau hais tias qhov ntsuas hluav taws xob poob ntawm tag nrho cov shunts siv yog zoo ib yam nrog cov ammeter, piv txwv li, 75mV. Nyob rau hauv no txoj kev, tom qab lub shunt raug xaiv, tag nrho cov teev ntawm lub ammeter yog tus nqi tam sim no ntawm cov xaiv shunt, thiab ntau yam ntawm ammeter (uas yog, tam sim no ib feem ntawm lub dial scale) yog qhov ntsuas tam sim no. lub shunt muab faib los ntawm tag nrho cov naj npawb ntawm division ntawm dial scale.
Muaj cov slotted thiab tsis-slotted shunts rau DC tam sim no ntsuas. Lub shunt muaj manganese-nickel-tooj liab alloy tiv thaiv rods thiab tooj liab strips, thiab yog plated nrog npib tsib xee. Nws cov nominal voltage poob yog 60mV, tab sis nws kuj muaj xws li 75, 100, 120, 150 thiab 300 mV.
Qhov ntsuas tam sim no ntawm qhov hom shunt yog raws li nram no: 5A, 10A, 15A, 20A thiab 25A.
Tsis-slot shunts muaj nyob rau hauv cov qauv ntu ntawm 30 A txog 15 kA.
