Txheem
Cov hluav taws xob hluav taws xob yog qhov tshwj xeeb hauv kev nkag siab tias cov khoom me me ua lub luag haujlwm tseem ceeb tshaj plaws hauv lawv.
Lub fuse yog ib qho ntawm cov khoom siv me me rau tus kheej uas tiv thaiv lub zog tsis txaus ntseeg uas tuaj yeem ua rau tag nrho cov hluav taws xob tsis zoo.
Puas yog lub cuab yeej hauv koj lub tsev lossis lub tsheb tsis tau txais hluav taws xob? Koj puas xav tias qhov teeb meem nyob hauv lub thawv fuse? Yuav ua li cas koj thiaj paub yog tias lub fuse yog cua tshuab, uas tuaj yeem ua rau koj qhov teeb meem?
Tsuas yog ob peb kauj ruam yooj yim, koj yuav kawm paub yuav ua li cas ntsuas lub fuse nrog multimeter los ntawm phau ntawv qhia no.
Cia peb pib.
Lub fuse ua haujlwm li cas?
Fuses yog cov khoom siv yooj yim tsim los tiv thaiv hluav taws xob hluav taws xob los ntawm lub zog hluav taws xob los yog overloads.
Lawv feem ntau muaj cov hlua hlau me me lossis cov hlau uas yaj los yog "tshuab" thaum dhau tam sim no dhau los ntawm nws. Tam sim no uas lub fuse tuaj yeem tuav tau yog hu ua nws qhov ntsuas tam sim no, uas txawv ntawm 10A txog 6000A.
Feem ntau hom fuse siv nyob rau hauv ntau yam kev siv hluav taws xob yog lub cartridge fuse, uas yog cylindrical nyob rau hauv cov duab, feem ntau pob tshab, nrog ob hlau lugs ntawm ob tog.
Hauv nws yog ib txoj hlua hlau uas txuas ob lub davhlau ya nyob twg thiab kub hnyiab tawm ntawm qhov tam sim no ntau dhau los tiv thaiv qhov ntws ntawm hluav taws xob tam sim no ntawm lawv.
Cov cuab yeej xav tau los kuaj xyuas lub fuse
Txhawm rau kuaj lub fuse koj xav tau:
- multimeter
- Automotive Fuse Puller
Yuav ua li cas txheeb xyuas lub fuse nrog multimeter
Teem koj lub multimeter mus rau 200 ohm ntau los ntsuas qhov tsis kam, tso lub multimeter qhov tsis zoo thiab qhov kev sojntsuam zoo ntawm txhua qhov kawg ntawm lub fuse, thiab tos kom txog thaum kev nyeem ntawv yog xoom (0) lossis ze rau xoom, uas txhais tau hais tias lub fuse zoo. Yog tias koj tau txais "OL" nyeem ntawv, ces lub fuse tsis zoo thiab yuav tsum tau hloov.
Peb yuav ua tib zoo saib xyuas txhua yam ntawm cov kauj ruam no, nrog rau txhua kauj ruam tseem ceeb.
- Tshem tawm lub fuse
Thawj kauj ruam yog tshem tawm lub fuse ntawm lub Circuit Court nws nyob rau hauv. Tau kawg, yuav ua li cas lub fuse raug tshem tawm nyob ntawm Circuit Court, ntaus ntawv, lossis hom fuse.
Txawm li cas los xij, ua ntej ua qhov no, txiav tawm lub hwj chim qhov chaw kom tsis txhob muaj hluav taws xob poob. Koj kuj yuav tsum tau ceev faj thaum tshem lub fuse kom tsis txhob ua kom puas.
- Teem lub multimeter rau ohms
Kev tshuaj xyuas fuses rau qhov yuam kev yuav tsum tau kuaj xyuas lawv cov kev tiv thaiv. Txhawm rau ntsuas qhov tsis kam nrog lub multimeter, koj tig nws lub xov tooj mus rau Ohm txoj haujlwm.
Kev teeb tsa ohm yog sawv cev los ntawm Omega (Ohm) lub cim ntawm lub multimeter thiab raws li koj yuav pom nws kuj muaj ntau yam (2 MΩ, 200 kΩ, 20 kΩ, 2 kΩ thiab 200 Ω).
Qhov txwv 200 ohm yog qhov tsim nyog uas koj tau teeb tsa koj lub multimeter rau vim nws yog qhov ze tshaj plaws ntau dua uas muab qhov tseeb tshaj plaws.
Tsis tas li ntawd, koj tuaj yeem teeb lub multimeter mus rau hom txuas ntxiv, uas feem ntau qhia los ntawm lub suab yoj lub cim.
Tam sim no, thaum lub sij hawm txuas ntxiv kuj tseem zoo rau kev kuaj xyuas yog tias ib txoj hlua hlau puas lawm los yog tsis, nws tsis muab cov ncauj lus kom ntxaws rau koj.
Qhov kev teeb tsa ohm yog qhov zoo tshaj plaws, raws li nws qhia koj yog tias lub fuse tsis zoo, txawm tias cov hlua hlau tsis tawg. Muab qhov tseem ceeb rau qhov kev teeb tsa ohm.
Txhawm rau xyuas seb lub multimeter tau teeb tsa kom raug, muab qhov zoo thiab qhov tsis zoo rau saum ib leeg.
Nrog rau qhov kev teeb tsa kom raug, koj yuav tau txais xoom (0) lossis ze rau nws nrog qhov teeb tsa ohm, lossis koj yuav hnov cov multimeter beep hauv hom nruam. Yog tias koj tau txais lawv, mus rau kauj ruam tom ntej.
- Muab multimeter coj mus rau txhua qhov kawg ntawm lub fuse
Ntawm no koj tsuas yog tso cov coj ntawm multimeter ntawm txhua qhov kawg ntawm tus pin fuse, tsis hais qhov polarity.
Kev ntsuas kev tiv thaiv tsis tas yuav tsum muaj kev tso kawm nruj ntawm qhov zoo lossis qhov tsis zoo ntawm ib qho kawg, yog li koj tsis tas yuav txhawj txog qhov ntawd. Tom qab cov xov hlau tau sib cuag kom raug, xyuas cov ntawv nyeem ntawm lub ntsuas ntsuas.
- Ntsuas cov txiaj ntsig
Cov txiaj ntsig tau yooj yim zoo nkauj. Hauv hom kev txuas ntxiv, yog tias lub multimeter beeps, nws txhais tau tias muaj kev txuas ntxiv ntawm ob lub ntsiab lus ntawm multimeter (hlau filament yog OK). Yog tias koj tsis hnov ib lub suab nrov, lub fuse tau tshuab thiab yuav tsum tau hloov.
Txawm li cas los xij, txawm tias thaum lub multimeter beeps, cov hlua hlau kuj tseem muaj qee qhov tsis xws luag, thiab qhov no yog qhov kev sim ntsuas qhov muaj txiaj ntsig.
Yog hais tias lub multimeter nyob rau hauv lub ohm teeb, zoo fuses yuav tsum muab rau koj ib tug kuj nqi ntawm xoom (0) los yog zero.
Qhov no txhais tau hais tias muaj txoj hauv kev txuas ntxiv ntawm ob txoj hauv kev ntawm multimeter (cov hlua hlau tseem zoo), thiab nws kuj txhais tau tias tam sim no tuaj yeem yooj yim ntws los ntawm nws yog tias xav tau.
Tus nqi saum toj no 1 txhais tau hais tias muaj kev tawm tsam ntau dhau hauv lub fuse, uas tej zaum yuav yog vim li cas tsis txaus tam sim no ntws los ntawm nws.
Lub multimeter kuj tseem tuaj yeem qhia koj "OL", qhia tias tsis muaj kev txuas ntxiv ntawm txhua lub fuse (cov hlua hlau yog tshuab) thiab lub fuse yuav tsum tau hloov.
Xyuas lub tsheb fuses nrog ib tug multimeter
Automotive fuses muaj qhov txawv txav, vim tias lawv muaj "cov hniav" ntawm ob sab, tsis yog protrusions. Lawv kuj siv sijhawm ntev dua li cov fuses li niaj zaus thiab nyob hauv lub thawv fuse.
Txhawm rau kuaj lub tsheb fuse, xyuas kom lub tsheb tawm, xyuas koj lub tsheb daim ntawv qhia fuse kom pom cov fuse tshwj xeeb rau cov khoom tsis raug, tom qab ntawd tshem lub fuse nrog lub fuse rub.
Tam sim no koj pom nws rau qhov chaw tsaus uas qhia tias muaj hluav taws kub lossis cua tshuab, lossis sim xyuas seb txoj hlua puas yog lub fuse pob tshab. Lawv teeb liab fuse faulty uas yuav tsum tau hloov.
Yog tias koj tsis pom ib yam dab tsi tsis ncaj ncees lawm tom qab kuaj pom, ua raws li cov txheej txheem ntawm kev kuaj xyuas cov fuses nrog multimeter. Teem lub 'meter' mus rau 200 ohm ntau, tso lub multimeter sojntsuam ntawm ob lub ntsej muag kawg ntawm lub fuse, thiab xyuas cov nqi ntawm qhov screen tom qab kev sib cuag raug tsim nyog.
Yog tias koj tau txais xoom, tus nqi ze ze rau xoom, lossis lub suab nrov, lub fuse yog qhov zoo. Nyeem "OL" lossis lwm yam nqi txhais tau hais tias lub fuse tsis raug thiab yuav tsum tau hloov.
Thaum kawg, thaum hloov fuses, xyuas kom tseeb tias koj siv lub fuse tshiab nrog tib qhov kev ntsuas amperage li lub fuse ua tsis tiav. Koj ua qhov no kom tsis txhob txhim kho lub fuse uas rub tawm tam sim no ntau dua li qhov tsim nyog, uas tuaj yeem ua rau lub cuab yeej puas lossis Circuit Court nws tsim los tiv thaiv.

Thaum koj tuaj yeem kuaj lub fuse yam tsis muaj multimeter, digital multimeter yog qhov yooj yim tshaj plaws los txiav txim siab seb lub fuse puas phem. Nws kuj tseem siv tau rau lwm yam kev kuaj hluav taws xob.
xaus
Kev tshuaj xyuas fuses nrog lub multimeter yog ib qho ntawm cov txheej txheem kuaj hluav taws xob uas yooj yim tshaj plaws kom ua raws li yog tias koj ua raws li peb cov lus qhia. Koj tsuas yog tso multimeter probes ntawm txhua qhov kawg thiab tos rau lub suab nrov lossis tus nqi ze rau xoom.
Nco ntsoov tshem tawm cov fuse los ntawm cov khoom siv hluav taws xob ua ntej kuaj xyuas, thiab tseem yuav hloov lub fuse tsis zoo nrog lub fuse ntawm tib qhov ntsuas.
FAQ
Koj yuav ua li cas thiaj paub tias lub fuse tsis zoo?
Lub fuse muaj teeb meem yog tias koj pom tias nws cov xov tawg lossis muaj qhov tsaus ntuj ntawm nws, qhia tias muaj hluav taws. Koj kuj tseem siv lub tshuab ntsuas ntau los ntsuas qhov txuas ntxiv lossis tsis kam, uas yuav tsum nyob ze rau xoom.
Dab tsi yog qhov feem ntau ua rau lub tshuab cua meter fuse?
Qhov feem ntau ua rau cua tshuab fuses yog Circuit Court overload. Circuit Court overloading yog thaum ntau cov khoom siv kos tam sim no hauv Circuit Court los ntawm fuse, ua rau lub tshuab hluav taws xob.
