Cov tsheb thiab cov tsev qub uas tsis tau siv lub tshuab hluav taws xob niaj hnub no feem ntau yog nruab nrog fuses los tiv thaiv kev puas tsuaj thaum hluav taws xob nce. Qee zaum cov fuses no yuav tsum tau tshuaj xyuas kom paub tseeb tias lawv tseem ua haujlwm tau zoo. Kev ntsuas fuses tuaj yeem ua tiav siv lub ntsuas cua, uas yog ob qho sai thiab yooj yim kawm.
Cov kauj ruam
Txoj Kev 1 ntawm 2: Kawm paub txog fuses thiab multimeters
Kauj Ruam 1. Nkag siab txog fuses
Fuses tsuas yog cov xov hlau uas tsis tau ua kom kawg, tab sis lawv lub hom phiaj yog txhawm rau tiv thaiv kev puas tsuaj rau cov khoom siv hluav taws xob muaj txiaj ntsig lossis tiv thaiv hluav taws (tshwj xeeb hauv tsev) tshwm sim los ntawm lub zog nce. Yog tias ntau dhau tam sim no ntws los ntawm lub fuse, nws yuav hlawv thiab ua kom tawg hauv Circuit Court. Muaj ntau hom fuses, tab sis qhov sib txawv tsuas yog hauv qhov tsos. Nov yog cov lus piav qhia ntawm ob qhov feem ntau:
- Lub fuse yog lub fuse cylindrical uas yog yav tas los ntau zaus thiab ntev siv rau ntau yam khoom siv, los ntawm tsev mus rau cov khoom siv hluav taws xob me me. Lawv muaj cov ntsiab lus tiv tauj hlau ntawm ob qho kawg thiab suav nrog lub raj nrog xaim.
- Lub tiaj hniav fuse yog ib hom fuse siv hauv kev lag luam tsheb thiab tshwj xeeb tshaj yog nyob rau xyoo dhau los 20-30 xyoo. Lawv vaguely zoo li lub ntsaws ntawm lub hwj chim qaum, nrog ob lub hlau hlau tawm los ntawm lub tsev yas uas muaj cov xaim. Yav dhau los, feem ntau cov tsheb kuj tau nruab nrog cov iav me me. Cov hniav fuse yog qhov yooj yim ntxig rau hauv lub roj teeb, thiab xav tau qhov chaw me me los ntsaws rau hauv coob ntawm lawv ua ke.
Kauj Ruam 2. Kawm seb lub multimeter ua haujlwm li cas
Multimeters ntsuas AC thiab DC voltage, tiv thaiv hluav taws xob, thiab hluav taws xob tam sim no. Txhawm rau ntsuas fuse, koj tuaj yeem siv nws ua ohmmeter (ntsuas uas ntsuas qhov tsis kam) lossis ammeter (ntsuas uas ntsuas cov hluav taws xob tam sim no).
Lub multimeter muaj txoj kab zoo thiab tsis zoo. Thaum ntsuas kev tiv thaiv lossis tam sim no hauv Circuit Court, lub ntsuas cua yuav xa hluav taws xob me me los ntawm nws tus kheej lub roj teeb uas yog tom qab ntawd dhau los ntawm Circuit lossis khoom
Kauj Ruam 3. Nkag siab tias vim li cas koj yuav tsum sim fuses
Kev sim fuses yog txoj hauv kev yooj yim tshaj plaws kom paub seb muaj dab tsi tshwm sim hauv koj lub tsheb lossis hauv tsev cov khoom siv hluav taws xob. Tias yog vim li cas nws thiaj tseem ceeb heev uas koj yuav tsum paub qhov txuj ci no.
- Nws yog qhov yooj yim los ntsuas fuses dua li lwm yam khoom siv hluav taws xob. Lwm lub tsheb lossis cov khoom siv hauv tsev muaj cov kab hluav taws xob nyuaj ntawm qhov ntev. Ntxiv mus, feem ntau cov tsheb tsuas tuaj yeem kuaj hauv kev cob qhia tsheb, thiab qhov no cuam tshuam tus nqi sai. Kev ntsuas fuses nrog lub ntsuas cua yog qhov yooj yim thiab cov cuab yeej xav tau yog pheej yig thiab yooj yim rau kev khiav lag luam.
- Ntau hom fuses muab kev pom pom pom ntawm lub fuse kev ua haujlwm. Lawv yog pob tshab, yog li koj tuaj yeem pom yog tias cov xaim tseem nyob li qub. Yog tias qhov ib txwm ua kom dub, nws feem ntau yog vim lub fuse tau tshuab. Txawm li cas los xij, qee qhov fuse yuav qhia pom qhov dub tom qab tsuas yog ua kom sov me ntsis, thiab nws tseem tuaj yeem yog qhov tshwm sim ntawm qhov xwm txheej tsis tau tshawb pom lub lis piam lossis hli dhau los. Yog tias lub cuab yeej tsis ua haujlwm, koj yuav tsum sim cov fuses ua ntej. Yog tias txhua qhov fuses tseem ua haujlwm, yuav muaj teeb meem loj dua thiab nws yuav tsim nyog hu rau tus kws tshaj lij.
Txoj Kev 2 ntawm 2: Kuaj fuse
Kauj Ruam 1. Thawj zaug tua lub cuab yeej thiab tshem nws
Kauj Ruam 2. Tshem lub fuse ntawm lub tsheb lossis khoom siv
Xyuas kom nws raug tua ua ntej tshem lub fuse.
Kauj Ruam 3. Qhib thiab teeb lub ntsuas
- Koj tuaj yeem hloov qhov hloov mus rau Ω, lossis OHMS. Qhov no yuav ntsuas qhov tsis kam. Ua ntej sim fuse, muab cov xov hlau zoo thiab tsis zoo ua ke thiab nyeem cov ntaub ntawv. Tus lej qhia yuav tsum yog ze rau tus lej koj pom thaum koj sim cov fuses.
- Xwb, koj tuaj yeem ntsuas qhov hluav taws xob tam sim no los ntawm kev ntsuas lub ntsuas 'meter' hla lub cim, uas zoo li tus xub txav ntawm kab.
Kauj Ruam 4. Muab ib txoj hlua hlau tso rau ntawm txhua qhov kawg ntawm lub fuse thiab tom qab ntawd xyuas cov zaub
Txij li lub fuse me ntsis ntau dua li cov xov hlau - thiab tsis muaj qhov nyuaj - nws tsis muaj teeb meem twg sab twg tau txais cov xov tooj zoo lossis tsis zoo
Kauj Ruam 5. Kuaj lub fuse
- Thaum siv lub ntsuas ntsuas ntsuas Ohms, dab tsi nyeem yuav tsum sib phim (lossis ze li sib phim) qhov txiaj ntsig koj tau txais thaum ob lub xov hlau kov. Yog tias lub fuse tshuab, koj yuav tsis tuaj yeem nyeem dab tsi hlo li, lossis lub ntsuas yuav nyeem OL, nyob ntawm qhov tsim thiab hom ntsuas uas koj tab tom siv.
- Thaum siv digital multimeter teeb tsa txhawm rau ntsuas kev txuas mus ntxiv, lub ntsuas yuav tsum ua suab nrov tsis tu ncua thaum koj tuav cov xov hlau nyob ze qhov kawg ntawm lub fuse. Qhov ntawd txhais tau tias lub voj voog tiav. Yog tias qhov no tsis tshwm sim, lub fuse tau tshuab.
Lub tswv yim
- Raws li rau lub tsheb fuses, tsheb feem ntau siv cov xim tiaj tiaj ntsaws fuse, thiab yog tias koj saib rau sab saum toj ntawm lub fuse hauv qhov fuse compartment koj yuav pom tias muaj cov hlau hlau khiav ntawm qhov pom sab saum toj ntawm lub fuse thiab nws yog ib yam nkaus. (fuse zoo) lossis tawg (fuse tshuab).
- Kev teeb tsa tsev yuav tsum tsis yog tsuas yog tiv thaiv los ntawm fuses zoo tib yam niaj hnub no. Cov tshuab hluav taws xob niaj hnub no thiab cov cuab yeej tiv thaiv tsis xav tau fuses thiab tseem muaj kev nyab xeeb dua. Xav txog kev hloov qhov qub fuse teeb tsa nrog ib qho uas ua tau raws li cov qauv niaj hnub no.
Lus ceeb toom
- Tsis txhob sim fuse ntawm lub tshuab uas tseem muaj zog.
- Tsis txhob hloov lub tshuab cua tshuab lossis xav tias fuse nrog qhov ntsuas siab dua. Lawv tau tsim los rau kev nyab xeeb thiab koj yuav tsum hloov lawv nrog lub fuse nrog qhov tseeb (lossis qee zaum qis dua) ntsuas raws li qhov qub.
