3 txoj hauv kev los ntsuas Circuit Court txuas ntxiv nrog multimeter
1, Voltage ntsuas txoj kev.
Ua ntej, lub hwj chim ntawm cov tswj Circuit Court thiab kho lub multimeter iav hloov mus rau AC voltage theem 750V. Xa mus rau lub voj voog schematic, ib qho kev sojntsuam ntawm multimeter tseem nyob ntawm kab 9, thaum lwm qhov kev sojntsuam ntsuas kab 8-7-6-5-4-3. Thaum qhov hloov pauv tsis raug kaw, ob qhov kev sojntsuam yog nyob rau theem thiab qhov voltage yog 0V. Thaum ntsuas kab 2-1, ob qhov kev sojntsuam yog nyob rau theem sib txawv thiab qhov hluav taws xob nyob ib puag ncig 380V. Qhov no yog lub xeev qub ntawm lub voj voog. Yog hais tias tus nqi hluav taws xob ntawm ib kab lossis taw tes tsis sib xws hauv Circuit Court schematic thaum lub sijhawm ntsuas txheej txheem, feem ntau, qhov taw tes nrog tus nqi hluav taws xob tsis raug yog qhov txhaum!
2, Kev ntsuas kev tiv thaiv.
Ua ntej, lub Circuit Court yuav tsum tau muab tua, sim, thiab paub tseeb tias tuag. Tom qab ntawd, lub multimeter iav hloov yuav tsum tau teem rau lub beep los yog kuj hom, thiab ob probes ntawm lub multimeter yuav tsum tau muab tso rau ntawm kab 1 thiab kab 9 feem.
Nyob rau hauv ib txwm muaj xwm txheej, nias lub pob SB1 lossis SB2 nyias, lossis manually nias lub springs ntawm ob lub AC contactors cais (piv txwv li manually kaw qhov nquag qhib ntawm KM1 lossis KM2). Lub sijhawm no, 1-9 yuav ua tau thiab lub voj voog yuav qhib. Lub multimeter yuav muaj qhov sib thooj coil kuj tus nqi.
Yog tias tsis muaj tus nqi tiv thaiv, nws qhia tau hais tias lub Circuit Court tsis txuas. Nws yog ib qho tsim nyog los sib piv lub voj voog schematic thiab ntsuas thiab txheeb xyuas qhov txuas txuas ntxiv los ntawm taw tes. Txoj kev ntsuas yog zoo ib yam li voltage.
3, Txoj kev ntsuas kev tiv thaiv thiab ntsuas qhov ntsuas hluav taws xob ntawm lub tshuab hluav taws xob yog ob txoj kev siv ntau tshaj plaws hauv kev kuaj xyuas qhov txhaum. Nws tuaj yeem hais tias txhua tus muaj nws tus kheej zoo thiab yooj yim. Qhov tseem ceeb yog txoj kev uas koj ib txwm siv, thiab siv lub multimeter los ntsuas nrog kev pab los ntawm koj txoj kev paub tshaj plaws.
Muaj kwv yees li ob yam hais txog qhov kev sib txuas ntawm cov khoom siv hluav taws xob: thawj zaug, qhov khoom siv hluav taws xob, thiab qhov thib ob, cov khoom siv hluav taws xob. Txhawm rau txheeb xyuas cov khoom siv hluav taws xob, kho qhov ntsuas qhov ntsuas ntawm lub multimeter mus rau qib siab dua li qhov ntsuas hluav taws xob ntawm qhov ntsuas hluav taws xob. Piv txwv li, yog tias koj lub hwj chim tam sim no yog AC 220V, ces yog tias koj lub multimeter yog pointer hom, qib yuav tsum tau teem rau AC 250V lossis AC 300V. Yog tias koj siv digital multimeter, koj tuaj yeem teeb tsa rau AC 750V. Tom qab ntawd ntxig qhov kev sojntsuam dub rau hauv COM thiab cov kev sojntsuam liab rau hauv V Ω socket. Txawm hais tias ntsuas AC voltage tsis tas yuav muaj qhov polarity siab, qhov no yog qhov yuav tsum tau siv lub ntsuas ntsuas ( https://www.dgzj.com/ Yog li ntawd, nws yog ib qho tseem ceeb los txhim kho tus cwj pwm ua haujlwm zoo. Yog tias koj ntsuas thawj zaug, thov Ua tib zoo saib xyuas kev nyab xeeb ib yam li peb feem ntau siv cov chopsticks noj, ntxig ob qhov kev sojntsuam tsis tu ncua mus rau hauv lub qhov hluav taws xob lossis cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob ntawm lub sijhawm no, lub multimeter yuav tso saib qhov tam sim no voltage , yog hais tias lub hwj chim mov voltage yog ib txwm, lub hwj chim mov ib feem yuav raug tshem tawm txwv tsis pub, xyuas lub Circuit Court ntawm lub qhov (socket) thiab lub tis vaj huam sib luag hloov, nrog rau lub hwj chim hloov ntawm lub Circuit Court no, cov kauj ruam tom ntej yog los ntsuas seb lub tshuab hluav taws xob pancake Kev sib txuas ua ntej, txiav lub tshuab hluav taws xob los ntawm lub zog hluav taws xob, kho lub tshuab multimeter mus rau qhov tsis kam ntawm 200 Ω, thiab ntsuas lub hwj chim qaum, hloov hluav taws xob, hloov qhov kub thiab txias, thiab cov khoom cua sov ntawm lub tshuab hluav taws xob sib cais. Nyob rau theem ntawm kev ntsuas no, tshwj tsis yog rau cov cua sov ntawm lub tshuab hluav taws xob, qhov ntsuas ntsuas yuav tsum nyob ib puag ncig 1 Ω. Txwv tsis pub, qhov teeb meem hauv ntu no yuav tsum tau hais.
