5 lub ntsiab siv ntawm clamp ammeters
Feem ntau, thaum ntsuas tam sim no nrog lub ammeter li niaj zaus, nws yog ib qho tsim nyog los txuas lub ammeter nyob rau hauv series rau Circuit Court rau kev ntsuas tom qab fais fab tuag Circuit Court. Qhov no yog teeb meem heev, thiab qee zaus cov kev khiav hauj lwm ib txwm tsis tso cai rau qhov no. Hauv qhov no, siv lub clamp ammeter yuav yooj yim dua. Lub clamp ammeter tuaj yeem ntsuas qhov tam sim no yam tsis tau txiav tawm ntawm lub voj voog, tsuav yog tias cov hlau raug ntsuas yog clamped hauv lub clamp. Txawm li cas los xij, clamp gauges feem ntau muaj qhov tseeb tsawg, feem ntau yog li ntawm 2.5 mus rau 5 qib, thiab feem ntau tsuas yog siv thaum qhov hluav taws xob ntawm qhov ntsuas hluav taws xob tsis tshaj 500V.
Muaj ntau ntau hom thiab hom ntawm clamp ammeters. Piv txwv li, T-301 clamp ammeter tsuas yog siv los ntsuas AC tam sim no, thaum T-302 clamp ammeter tuaj yeem ntsuas AC tam sim no thiab AC voltage. Lub MG24 hnab tshos clamp ammeter kuj tuaj yeem ntsuas AC tam sim no thiab AC voltage; Kuj tseem muaj clamp hom ammeters rau AC thiab DC, xws li MG21 thiab MG22 qauv. Thaum ua kev ntsuas, ntau hom clamp ammeters yuav tsum raug xaiv raws li cov khoom sib txawv raug ntsuas. Yog tias tsuas ntsuas AC tam sim no, T-301 clamp ammeter tuaj yeem xaiv. Yog tias siv lwm hom clamp ammeters, qhov hloov pauv hloov yuav tsum tig mus rau qhov xav tau raws li qhov ntsuas khoom.
Raws li cov qauv kev nyeem ntawv, clamp ammeters tuaj yeem muab faib ua ob pawg: hom pointer thiab hom digital; Los ntawm qhov kev xav ntawm qhov hluav taws xob hauv Circuit Court, muaj cov ntsuas hluav taws xob qis thiab cov ntsuas hluav taws xob high-voltage clamp gauges; Los ntawm kev pom kev ua haujlwm, clamp tam sim no ntsuas xws li AC clamp meters zoo tib yam, AC / DC dual-purpose clamp meters, to tam sim no clamp meters, clamp meters nrog multimeters, thiab lwm yam.
Lub ntsuas ntsuas tsis tu ncua tsuas yog siv los ntsuas AC tam sim no thiab ntsuas tsis tau lwm yam hluav taws xob tsis zoo. Lub clamp meter nrog multimeter muaj nuj nqi yog ib qho ntxiv rau lub ntsuas ntsuas, thiab nws txoj kev siv yog tib yam li ntawm multimeter.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub digital clamp saib yog qhov pib zoo ib yam li ntawm lub pointer clamp saib. Qhov txawv yog tias lub vijtsam LCD siv los tso saib cov txiaj ntsig ntawm cov lej. Qhov loj tshaj plaws yog tias tsis muaj kev nyeem ntawv yuam kev, muaj peev xwm nco qab ntsuas cov txiaj ntsig, thiab muaj peev xwm ntsuas ua ntej thiab tom qab ntawd nyeem.
Tom ntej no, cia peb saib cov qauv thiab kev ua haujlwm ntawm lub clamp ammeter
Cov qauv ntawm magneto hluav taws xob clamp ammeter
Lub magneto hluav taws xob clamp ammeter feem ntau muaj xws li ib tug tshwj xeeb tam sim no transformer, ib tug rectified magneto fais ammeter, thiab nyob rau hauv circuits. Cov qauv sib xws yog T301 thiab T302. Lub T301 clamp hom ammeter tsuas tuaj yeem ntsuas AC tam sim no, thaum T302 hom tuaj yeem ntsuas AC tam sim no thiab AC voltage. Kuj tseem muaj AC thiab DC dual-purpose hnab tshos clamp ammeters, xws li MG20, MG26, MG36 thiab lwm yam qauv. Cov tsos ntawm T301 clamp zoo li tus saib yog pom hauv daim duab 7-6. Nws qhov tseeb yog qib 2.5, thiab qhov tam sim no yog: 10 A, 50 A, 250 A, 1000 A.
