Yuav Ua Li Cas Ntsuam Xyuas Cov Transformer nrog Multimeter (4-Step Guide)
Txheem
Transformers yog cov khoom siv hluav taws xob tseem ceeb uas hloov lub zog ntawm ob lossis ntau lub voj voog. Txawm li cas los xij, qee zaum lawv tuaj yeem ua tsis tau thiab ua rau lub cev tsis ua haujlwm. Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tau sim lub transformer kom koj cov cuab yeej ua hauj lwm yam tsis muaj kev pheej hmoo ntawm hluav taws kub los yog tej yam xwm txheej txaus ntshai.
Muaj ntau txoj hauv kev rau kev sim transformers, thiab qhov zoo tshaj plaws yog digital multimeter. Yog li, nyeem rau thiab nrhiav seb yuav ua li cas kuaj lub tshuab hluav taws xob nrog multimeter! Phau ntawv qhia no yuav coj koj mus ib kauj ruam!
Txheeb xyuas cov teeb meem Transformer
Muaj ntau txoj hauv kev los txiav txim siab seb koj lub tshuab hloov pauv tsis zoo, thiab digital multimeter yog ib qho ntawm lawv. Lub DMM yog cov cuab yeej siv tau zoo tshaj plaws rau kev kuaj xyuas qhov tsis raug ntawm qhov hloov pauv, sib nrug los ntawm nws txoj haujlwm tseem ceeb ntawm kev kuaj xyuas qhov voltage, tam sim no, thiab lwm yam. Yog tias txhua yam ua tau zoo, koj yuav tsum tuaj yeem nrhiav cov kev hloov pauv tsis raug thiab kawm kho lawv. nws tuaj yeem ua haujlwm li qub.
Yog li ntawd, ua ntej koj pib sim ib tug transformer nrog ib tug multimeter, nws yuav yog qhov zoo tshaj rau thawj zaug txheeb xyuas cov ntaub ntawv tseem ceeb ntawm transformers. Yog li ntawd, koj yuav tsum:
Visually soj ntsuam lub transformer
Ib qho laj thawj ntawm kev hloov pauv tsis ua haujlwm yog overheating, uas ua rau cov hlau sab hauv ntawm lub tshuab hloov pauv mus rau qhov kub siab. Yog li ntawd, lub transformer los yog qhov chaw nyob ib ncig ntawm nws yog feem ntau lub cev deformed. Tsis txhob kuaj lub transformer yog tias nws yog sab nraud o los yog hlawv, tab sis hloov nws.
Nrhiav kom paub qhov txuas ntawm lub transformer
Cov xaim yuav tsum tau cim kom meej meej ntawm lub transformer. Txawm li cas los xij, txoj hauv kev yooj yim tshaj plaws los txiav txim siab seb lub tshuab hluav taws xob sib txuas li cas yog kom tau txais daim duab kos duab. Koj tuaj yeem pom daim duab kos duab hauv cov ntaub ntawv cov khoom lossis ntawm cov chaw tsim khoom hauv lub vev xaib. (1)
Paub cov sab ntawm lub transformer
Lub 24V transformer muaj thawj (siab voltage) sab thiab ib nrab (tsis tshua muaj hluav taws xob) sab.
- Thawj (siab voltage) sab yog kab hluav taws xob ntawm lub transformer thiab cov hluav taws xob sib txuas rau cov khoom siv hluav taws xob, feem ntau yog 120 VAC.
- Qhov thib ob (tsis tshua muaj hluav taws xob) sab yog lub zog hloov mus rau 24 volts.
Nyob rau hauv lub transformer siv rau 24V daim ntawv thov, tsis muaj kev sib txuas hluav taws xob ncaj qha ntawm qhov siab thiab qis sab.
Yuav Ua Li Cas Ntsuas Transformer nrog Multimeter (Cov kauj ruam)
Hauv phau ntawv qhia no, peb yuav sim 24V transformer thiab koj yuav xav tau cov hauv qab no:
- Ntsia thawv
- multimeter
Yog li, yuav ua li cas txheeb xyuas lub hwj chim transformer nrog multimeter? Ua li no:
Kauj Ruam 1: Tshem cov npog hluav taws xob
Tshem tawm lub zog hluav taws xob. Tshem tawm tag nrho cov hluav taws xob npog npog lub transformer nrog lub hau ntswj. Kuv pom zoo kom kuaj xyuas cov chaw tsim khoom cov lus qhia kom paub meej tias kev nkag mus rau transformer.
Kauj ruam 2: Ntxig cov xov hlau rau hauv lub multimeter
Hloov qhov chaw multimeter mus rau "Ohm", tom qab ntawd ntxig qhov ntsuas liab thiab dub coj mus rau hauv multimeter. Qhov kev sojntsuam dub nkag mus rau hauv lub qhov txheem, thiab qhov kev sojntsuam liab nkag mus rau hauv Ohm qhov (socket). Tom qab ntawd, txuas qhov kawg ntawm ob lub xov hlau ua ke. Nws yuav tsum qhia xoom ohms los yog kaw Circuit Court.
Kauj Ruam 3: Txuas Leads mus rau Sab Nraud
Txuas lub multimeter coj mus rau sab siab lossis thawj coj ntawm lub transformer. Lub 'meter' yuav tsum txheeb xyuas qhov kev nyeem ntawv tsis kam, thiab hom transformer siv hauv Circuit Court yuav cuam tshuam qhov kev nyeem ntawv no. Yog hais tias lub 'meter' qhia tau hais tias qhib Circuit Court los yog infinite kuj, koj yuav tsum tau hloov lub siab sab transformer.
Kauj Ruam 4: Ua tib yam nrog rau sab thib ob
Ua raws li cov txheej txheem tib yam nyob rau hauv kauj ruam 3 rau kev sib txuas ntawm sab qis voltage los yog nyob rau hauv lub thib ob Circuit Court. Lub ' meter ' yuav tsum tshaj tawm qhov ntsuas qhov tseeb ntawm kev tiv thaiv hauv ohms rau sab hauv qab. Tom qab ntawd, yog hais tias lub multimeter qhia ib tug infinite los yog dav qhib nyeem ntawv, qhov tsawg voltage sab yog puas nyob rau hauv thiab lub transformer yuav tsum tau hloov.
Cov lus qhia yooj yim
- Lub suab buzzing lossis crackling yog ib qho kev ceeb toom uas ib qho transformer tab tom yuav hlawv.
- Thaum koj kov cov probes thiab tsuas yog ib sab ntawm lub transformer tsis ua haujlwm, koj yuav hnov lub suab nrov. Nyob rau hauv rooj plaub no tsis muaj tam sim no ntws los ntawm lub transformer thiab nws sim ua hauj lwm tawm tsam nws tus kheej.
- Tsis txhob xav tias thawj thiab theem nrab ntawm lub transformer txuas nrog tib lub hauv av hluav taws xob. Lawv feem ntau raug xa mus rau ntau qhov chaw. Yog li ntawd, yuav tsum ceev faj nrog kev sib cais hauv av thaum ua kev ntsuas.
- Koj tuaj yeem tshawb xyuas qhov kev ncaj ncees ntawm lub transformer. Kev tshuaj xyuas qhov txuas ntxiv ntawm qhov hloov pauv yog qhov tseem ceeb kom pom tias puas muaj txoj hauv kev rau hluav taws xob hla ntawm ob lub ntsiab lus sib cuag. Yog tias tsis muaj txoj hauv kev tam sim no, ib yam dab tsi tau ploj mus hauv koj lub transformer thiab yuav tsum tau kho.
Меры предосторожности
Txhawm rau kuaj xyuas qhov hloov pauv kom nyab xeeb, cov hauv qab no yuav tsum raug coj mus rau hauv tus account:
- Tshem tawm tag nrho lub zog ntawm lub cuab yeej lossis cov cuab yeej ua ntej ua qhov kev sim. Tsis txhob sim ib lub cuab yeej txuas nrog lub zog sab nraud.
- Ib txwm sim hauv qhov chaw nyab xeeb, qhuav kom deb ntawm menyuam yaus thiab tsiaj.
- Kev sib cuag nrog lub zog hluav taws xob thaum lub voj voog qhib thiab lub zog rau kev sim yuav ua rau hluav taws xob poob lossis puas tsuaj. Siv tsuas yog DMM ua rau kov lub voj voog.
- Kev ua haujlwm nrog hluav taws xob yog qhov txaus ntshai heev. Yog li ntawd, yuav tsum ceev faj thaum ua li ntawd. Tsis txhob tig lub tshuab hluav taws xob nrog cov xov hlau frayed lossis pom kev puas tsuaj, vim qhov no tuaj yeem ua rau hluav taws xob poob siab.
- Tsuas yog kuaj lub transformer yog tias koj paub txog cov khoom siv hluav taws xob thiab tau siv multimeter los ntsuas qhov hluav taws xob, tam sim no, thiab kev tiv thaiv ntau yam ntawm qhov tseem ceeb.
Transformer: nws ua haujlwm li cas? (Bonus)
Lub transformer yog ib qho khoom siv hluav taws xob tseem ceeb uas hloov qhov hluav taws xob ntawm qhov hloov pauv tam sim no (AC) teeb liab. Qhov no yog ua tiav los ntawm kev hloov AC hluav taws xob rau hauv siab lossis qis voltage signals. Qhov no yog qhov tseem ceeb vim tias nws ua kom muaj kev nyab xeeb ntawm kev xa hluav taws xob hla kev deb. Xwb, koj tuaj yeem siv lub tshuab hloov pauv kom nce lossis nqis qis ntawm qhov hluav taws xob ntawm AC teeb liab ua ntej nws nkag mus rau hauv lub tsev.
Transformers tuaj nyob rau hauv ntau qhov ntau thiab tsawg thiab teeb tsa, tab sis lawv txhua tus ua haujlwm los ntawm kev tsim cov hlau nplaum nyob ib ncig ntawm ob lub coils ntawm hlau, hu ua windings. Ib qho winding txuas ncaj qha mus rau AC qhov chaw, zoo li cov kab hluav taws xob. Ntawm qhov tod tes, lwm qhov winding txuas nrog cov khoom siv hluav taws xob, xws li lub teeb pom kev zoo. Thaum tam sim no dhau los ntawm ib lub kauj, nws tsim ib qho chaw sib nqus uas nyob ib puag ncig ob lub kauj. Yog tias tsis muaj qhov sib txawv ntawm ob lub voj voog no, lawv yuav ib txwm muaj qhov sib txawv polarity, ib qho taw qhia rau sab qaum teb thiab lwm qhov taw qhia sab qab teb. Yog li lub transformer generates alternating tam sim no.
Primary thiab Secondary
Lub hauv paus thiab theem nrab coils ntawm lub transformer yog cov hlau coils uas tsim cov alternating tam sim no. Thawj kauj yog txuas nrog ib txoj kab hluav taws xob thiab cov coil thib ob yog txuas nrog cov khoom hluav taws xob. Koj tuaj yeem hloov qhov tso zis hluav taws xob ntawm lub tshuab hluav taws xob los ntawm kev hloov pauv tus nqi tam sim no los ntawm txhua qhov winding. (2)
