Hluav taws xob hauv lub tsheb yog lub luag haujlwm rau ntau lub tshuab thiab subsystems. Teeb pom kev zoo, suab tshuab, cua txias, txawm li cas los xij, koj yuav tsis txawm pib lub cav yog tias lub zog tawm mus. Hmoov tsis zoo, ntau tus neeg tsav tsheb "ua luam dej" nyob rau hauv cheeb tsam no thiab tsis tas yuav muaj peev xwm tiv tau cov teeb meem hauv hluav taws xob hluav taws xob, txawm tias muaj teeb meem feem ntau tsuas yog cuam tshuam nrog lub tshuab hluav taws xob. Nws yog ib qho kev tiv thaiv mechanism uas feem ntau tawg thiab disorients tsav tsheb. Nyob rau hauv cov ntaub ntawv hauv qab no, peb yuav tham ntxiv txog qhov fuse yog dab tsi, nws ua haujlwm li cas thiab hloov nws li cas yog tias ib qho tsis ua tiav.
fuse yog dab tsi?
Lub fuse yog ib qho tshwj xeeb hloov khoom siv hluav taws xob, txoj haujlwm uas yog los tua hluav taws xob tiv thaiv los ntawm kev qhib los yog rhuav tshem (hluav taws) cov khoom siv hluav taws xob ua ntej thaum muaj hluav taws xob ntau dhau los ntawm lawv. Hais lus ntxhib, lub fuse yog ib qho kev tiv thaiv kev tiv thaiv tus kheej thaum muaj kev hem thawj rau txhua yam khoom siv hluav taws xob (hauv tsheb lossis khoom siv hluav taws xob). Ib hom kev txi rau tus kheej, hais lus piv txwv.
Fuse txoj cai
Tsheb siv fusiblefuses thiab raug xaiv raws li qhov ntsuas load peev xwm. Thaum muaj xwm txheej ceev, thaum qhov hluav taws xob nce, lub fuse fuse tawg thiab qhib hluav taws xob hluav taws xob.
Tus txheej txheem ntawm kev rhuav tshem tus kheej pib thaum:
- luv luv - tshwm sim yog tias cov rwb thaiv tsev ntawm cov khoom siv hluav taws xob tau tawg lossis tsis raug kev sib txuas ntawm cov khoom siv. Qhov teeb meem ntawm frayed rwb thaiv tsev cables nyob rau hauv ib lub tsheb feem ntau yog ib qho ntawm feem ntau ua rau cua tshuab fuses.
- Incompatibility ntawm lub zog ntawm cov neeg siv khoom thiab cov ntsuas tam sim no tso cai rau ib qho hluav taws xob hluav taws xob. Qhov teeb meem no tau ntsib los ntawm cov neeg uas txiav txim siab los teeb tsa cov khoom siv hluav taws xob ntxiv hauv lawv lub tsheb (teeb pom kev zoo, xov tooj cua kaw suab thiab lwm yam zoo li lawv). Xws li cov neeg siv khoom muaj zog ntawm lub zog yog siv los ntawm cov kab hluav taws xob yooj yim, uas tsis yog tsim los rau cov khoom siv tam sim no. Vim tias qhov tam sim no dhau lawm, cov xov hlau yaj thiab ua rau luv luv, uas ua rau lub fuses tsis ua haujlwm.
Fuse Threshold
Los ntawm cov lus saum toj no, nws pom tseeb tias lub fuse hauv lub tsheb raug puas tsuaj yog tias tus nqi hluav taws xob ntau dhau. Lub fuse fuse overheats thiab hlawv tawm.
Tus ntsuas tam sim no ntawm lub fuse yog xam los ntawm tus qauv: Inom=Pmax/U.
- Inom yog qhov ntsuas tam sim no ntsuas hauv Amps;
- Pmax yog qhov siab tshaj plaws uas tuaj yeem ua haujlwm tauib qho khoom siv lossis lwm qhov. Lub zog yog qhia ntawm cov twj paj nruag thiab ntsuas hauv Watts;
- U yog qhov ntsuas hluav taws xob loj. Qhov ntsuas no ntsuas hauv Volts. Qib voltage hauv lub tsheb network yog 12 Volts.
Fuse yam
fuses raug cais los ntawm lub zog ntsuas raws li qhov loj ntawm fuse.
Fuses muab faib los ntawm qhov loj me rau hauv:
- Micro - lub compact tshaj plaws.
- Mini - loj me ntsis (16 millimeters).
- Ib txwm - qhov loj me (19 millimeters).
- Maxi yog qhov loj tshaj plaws (34 mm).
Qhov twg tseem ceeb dua yog kev faib los ntawm lub zog tam sim no. Txhawm rau kom yooj yim, lawv txhua tus tau cim nrog qee cov xim, tab sis koj yuav tsum tsis txhob tsom rau xim ib leeg, txij li cov fuses hauv VAZ tsheb tau cim nrog cov xim txawv ntawm cov tsheb txawv teb chaws, vim tias tsis muaj cov qauv hauv cheeb tsam no.
Fuse qhov chaw
Thawj qhov uas tus neeg tsav tsheb yuav tsum tau ntsib thaum sim tshuaj xyuas qhov xwm txheej ntawm lub fuses lossis hloov lawv yog kev tshawb nrhiav qhov thaiv kev nyab xeeb. Qhov tseeb yog tias nrhiav kom paub qhov twg fuse nyob tsis yog ib txoj haujlwm tseem ceeb. Hauv cov qauv sib txawv ntawm lub tsheb, lub thawv fuse yog nyob rau hauv ntau qhov chaw ntawm lub tsev lossis txawm nyob hauv qab lub hood. Qee lub sij hawm tus naj npawb ntawm fuses nce ntau heev, thiab cov chaw tsim khoom pib tso ob peb lub blocks hauv ntau qhov chaw ntawm lub tsheb. Vim tias qhov tsis meej pem no, nws tsuas yog tsis yooj yim sua kom muab lub universal circuit lossis kev qhia kom nrhiav tau qhov thaiv kev nyab xeeb. Piv txwv li,Hauv cov tsheb tsim hauv tsev, fuses nyob hauv qab lub hood (qhov chaw classic rau Zhiguli). Hauv cov tsheb txawv teb chaws, qhov xwm txheej nyuaj dua. Lub fuses nyob rau hauv Toyota Corolla yog nyob rau sab xis ntawm lub kauj tsheb ntawm lub dashboard. Nws yuav zoo li tias cov neeg tsim khoom ntawm ib lub tebchaws yuav tsum zoo sib xws hauv kev xaiv qhov chaw ntawm cov ntsiab lus, tab sis qhov tseeb txhua yam txawv. Fuses nyob rau hauv Nissan Almera nyob rau sab laug ntawm lub kauj, nyob rau hauv ib lub hnab me me.
Kaws fuses
Ib lub fuse ua haujlwm yog kev nyab xeeb ua ntej. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum ua kom lawv nyob hauv kev ua haujlwm. Yog tias ib qho ntawm cov khoom siv hluav taws xob hauv lub tsheb tsis zoo, nws yog ib qho tsim nyog los xyuas qhov kev ua tau zoo ntawm cov khoom. Yuav ua li cas? Ntau tus neeg tsav tsheb tsuas yog nkag mus rau lub thawv fuse thiab tshem tawm cov fuses ib zaug kom pom qhov muag ntsuas lawv tus mob. Cov tswv tsheb tsuas yog saib xyuas seb lub jumper hauv lub fuse puas puas lawm. Tau kawg, txoj kev no ua haujlwm, tab sis nws yog ib qho tseem ceeb rau cov neeg nyiam ua haujlwm, thiab tsis tas li ntawd, nws tsis yog ib txwm ntseeg tau, vim tias lub jumper tuaj yeem nyob twj ywm txawm tias lub fuse tau tshuab. Txhawm rau txheeb xyuas qhov xwm txheej ntawm qhov chaw, nws yog qhov zoo dua los qhib lub voj voog uas tsis ua haujlwm (nws tuaj yeem yog cov khoom siv hluav taws xob, xws li lub taub hau, lub qhov cub lossis lub tso suab), thiab tom qab ntawd siv multimeter los xyuas qhov voltage. nyob rau hauv lub fuse lub luag hauj lwm rau lub Circuit Court no. Xws li daim tshev yuav siv sij hawm tsawg dua thiab yuav muab qhov tseeb.
Kev hloov pauvfuses
Yog tias lub fuse tawg lawm, nws yuav tsum tau hloov tam sim ntawd. Ua ntej, peb pom lub thawv fuse (yog tias lub thawv nyob hauv qab lub hood, ces lub roj teeb yuav tsum tau txiav ua ntej). Peb tshem cov bolts ntawm lub hau ntawm lub thaiv kev ruaj ntseg. Nrog ib tug 10 wrench, unscrew lub txiv ntseej uas tuav lub clamp nrog nyob ntawm tej. Qhov no yog ua kom txav lawv (lawv thaiv kev nkag mus rau lub fuses). Tsis tas li ntawd, kom muaj kev nplij siab ntau dua, koj tuaj yeem rhuav tshem lub vaj huam sib luag fuse, tab sis qhov no tsis tsim nyog. Tom qab ntawd peb tsuas yog tshem tawm cov fuse uas tsis ua haujlwm thiab muab ib qho tshiab rau hauv nws qhov chaw (naturally, haum rau qhov loj thiab tus nqi).
Xaiv thiab kuaj lub fuse
Thaum xaiv lub fuse koj xav tau, koj yuav tsum nco ntsoov ntau yam xwm txheej. Thaum xaiv ib feem tshiab, koj yuav tsum hu rau cov tuam txhab ntseeg siab nkaus xwb uas yog lub luag haujlwm rau qhov zoo ntawm lawv cov khoom. Nws raug nquahu kom sab laj nrog lwm tus neeg tsav tsheb uas muaj lub tsheb zoo ib yam thiab muaj kev thauj khoom ntawm lub tshuab hluav taws xob. Qhov no yog qhov tseem ceeb heev, txij li feem ntau ntawm cov fuses yog tsim nyob rau hauv Suav teb, uas tsis muaj leej twg tswj cov txheej txheem no. Vim cov khoom tsis zoo, koj tuaj yeem tsis tsuas yog rhuav tshem cov khoom siv hluav taws xob, tab sis tag nrho lub tsheb. Muaj cov xwm txheej thaum lub thawv fuse hlawv tawm, thiab cov fuses lawv tus kheej tseem nyob ruaj khov.
txhawm rau txheeb xyuas qhov zoo ntawm qhov, nws yog ib qho tsim nyog yuav tsum ua kom luv luv Circuit Court sab nraum lub tsheb, thiab yog tias lub fuse hlawv tawm, ces nws yog qhov zoo thiab koj tuaj yeem nqa tag nrho cov khoom los hloov cov khoom puas. hauv kojauto.
Txhawm rau tsim qhov hluav taws xob luv luv, koj yuav tsum tau khi ib lub xaim mus rau qhov kawg ntawm lub fuse, thiab tom qab ntawd txuas ib qho ntawm lawv mus rau qhov ntxiv, thiab qhov thib ob rau qhov rho tawm thiab cia cov hluav taws xob ntws los ntawm lawv nrog. qhov voltage siab tshaj qhov nominal ib.
Txhim kho cov khoom siv
Yog tias koj npaj yuav txhim kho cov khoom siv ntxiv hauv lub tsheb, koj yuav tsum paub seb qhov kev xaim li niaj zaus ntawm koj lub tsheb tuaj yeem tiv taus qhov hnyav li no. Yog tias tsis yog, cov cuab yeej tshiab yuav tsum tau xaim nyias nyias, thiab qhov ntsuas fuse rau nws yuav tsum yog ib thiab ib nrab npaug siab dua qhov ntsuas tam sim no hauv Circuit Court. Txhawm rau xam cov load, koj tuaj yeem siv Ohm txoj cai thiab cov rooj tshwj xeeb.
