Yog vim li cas siv ib tug multimeter los ntsuas qhov voltage ntawm tshaj 20 volts thaum lub qhov (socket) tsis muaj hwj chim
Qhov no yog induced hluav taws xob.
Kev cuam tshuam: Nws yuav tsis cuam tshuam rau cov khoom siv zoo tib yam thiab tuaj yeem tsis quav ntsej. Cov cuab yeej tshwj xeeb precision yuav ua rau cov khoom puas tsuaj thiab yuav tsum tau cais tawm.
Yog vim li cas: Kev sib nrig sib inductance nrog rau lwm cov nyob fais fab cables nteg nyob rau hauv parallel
Lub qhov hluav taws xob hluav taws xob tsis muaj hluav taws xob, thiab lub tshuab hluav taws xob siv los ntsuas qhov hluav taws xob ntau dua 20 volts. Qhov xwm txheej no feem ntau tshwm sim los ntawm kev sib cuag tsis zoo ntawm cov hlau nyob ntawm AC lub zog. Ib ntus dhau los, Mr. Tony lub qhov hluav taws xob hauv peb lub zos tau ntsib qhov xwm txheej no.
Cov kab hluav taws xob hluav taws xob.
Mr. Tony yog ib tug neeg ua liaj ua teb me me thiab ua liaj ua teb txawj ntse, tab sis nws tsis paub dab tsi txog hluav taws xob. Kuv ntsuas qhov voltage ntawm nws lub tsev qhov (socket) nrog ib tug multimeter, thiab nws tsuas yog tshaj 30 volts. Raws li kev paub dhau los, yog tias qhov hluav taws xob ntawm lub qhov (socket) qis dhau mus txog qhov ntsuas tus nqi, nws feem ntau yog vim muaj teeb meem nrog kev sib cuag nrog nyob. Yog li kuv tau tsom mus xyuas cov xaim nyob hauv nws lub tsev, tshawb nrhiav thiab tshawb nrhiav, thiab pom tias cov ntsia hlau txuas cov cua hloov mus rau cov hlau nyob yog xoob me ntsis. Tony hais rau kuv tias cov hlau nyob yuav luag poob ntawm lub qhov taub ntawm lub qhov cua hloov lub hli dhau los, thiab nws tau ntxig cov hlau rau nws tus kheej. Kuv muab cov ntsia hlau ntsia hlau ntsia hlau thiab ntsuas tias qhov hluav taws xob ntawm lub qhov (socket) tau nce mus txog 100V. LED qhov taw qhia teeb ntawm lub qhov (socket) kuj tseem ci.
LED qhov taw qhia teeb ntawm lub qhov (socket) teeb.
Cov ntsia hlau tau nruj thiab qhov hluav taws xob tau nce mus rau 100V, tab sis nws tseem siv tsis tau. Kuv txuas ntxiv mus tshawb nrhiav thiab pom tias muaj ib daim kab xev hluav taws xob qhwv ib ncig ntawm ib qho ntawm cov xov hlau ntawm lub tshav puam. Tony tau hais rau kuv tias xyoo tas los no muaj ntau tus nas nkag los ntawm cov hlau no mus rau chav khaws nplej hauv lub tiaj nraum qaum tsev mus nyiag zaub mov. Tom qab ntawd, nws tau thaiv lub qhov nyob hauv chav, tej zaum vim cov nas nkag tsis tau thiab npau taws heev, tom ntawm cov hlau.
Kuv tau tshawb xyuas thiab pom tias qhov sib txuas ntawm 2 no 5-square aluminium hlau tau raug oxidized hnyav, qhia txog kev tiv thaiv tseem ceeb, ua rau lub qhov hluav taws xob tsis ncav cuag 220 volts. Yog li ntawd, aluminium hlau raug txiav thiab rov txuas dua, thiab cov ntaub nplaum hluav taws xob tau qhwv ib ncig ntawm nws. Tom qab ntawd, qhov hluav taws xob ntawm lub qhov (socket) tau ntsuas kom ncav cuag 220 volts.
