Fuse, feem ntau paub txog kev tuav pov hwm, yog ib qho ntawm cov khoom siv hluav taws xob uas yooj yim tshaj plaws. Thaum cov khoom siv hluav taws xob hauv lub hwj chim sib tshooj lossis cov khoom siv hluav taws xob ntau dhau los yog siv hluav taws xob luv luv, nws tuaj yeem tiv thaiv cov hluav taws xob hnyav thiab tiv thaiv kev kis tus huam yuaj.
Ib, qauv ntawm fuse
Thawj tsab ntawv r sawv rau fuse.
Tus thib ob tsab ntawv m txhais tau tias tsis muaj ntim kaw raj;
T txhais tau tias ntim cov hom raj;
U txhais tau tias kauv;
S sawv rau daim foos ceev;
C sawv rau plooj (porcelain ntxig;
Z sawv rau tus kheej-duplex.
Qhov thib peb yog tus tsim qauv ntawm lub fuse.
Plaub sawv cev rau qhov ntsuas uas muaj nyob tam sim no ntawm fuse.
Ob, kev faib tawm ntawm fuses
Raws li cov qauv, fuses tuaj yeem muab faib ua peb pawg: qhib hom, ib nrab-kaw hom thiab kaw hom.
1. QHIB HOM HABT
Thaum melt tsis txwv lub arc nplaim taws thiab cov hlau melting erection tam sim no tsis yog lub sijhawm loj, cov fuse yog feem ntau siv hauv kev sib xyaw nrog rab riam hloov.
2. Semi-txuas nrog fuse
Lub fuse yog ntsia hauv lub raj, thiab ib lossis ob qho tag nrho ntawm lub raj qhib. Thaum lub fuse yog melted, arc nplaim taws thiab cov hlau melting nyob rau hauv ib qho kev raug mob, tab sis nws tseem tsis muaj kev nyab xeeb txaus thiab siv tau tsuas yog muaj qee yam.
3. Nrog fuse
Lub fuse yog ntim tag hauv lub plhaub, tsis muaj arc ejection, thiab yuav tsis ua rau muaj kev txaus ntshai nyob ze ntawm ib feem Flying Arc thiab cov neeg ua haujlwm nyob ze.
Peb, fuse qauv
Lub fuse yog tsuas yog tsim ntawm cov yaj thiab cov raj fuse thiab fuse nrog rau uas mett yog ntsia.
1.Melt yog ib feem tseem ceeb ntawm lub fuse, feem ntau ua rau hauv cov kab ncauj lossis daim ntawv. Muaj ob hom melt cov ntaub ntawv, ib qho yog cov khoom me me me me, xws li cov hmoov txhuas, zinc, tin thiab tin-coj alloy; Lwm tus yog siab yaj taw cov ntaub ntawv, xws li nyiaj thiab tooj.
2.Qhov Tube Melt yog lub plhaub tiv thaiv ntawm yaj, thiab muaj cov txiaj ntsig ntawm extinguishing arc thaum cov yaj yog fused.
Plaub, fuse tsis
Cov kev ntsuas ntawm fuse saib rau cov tsis sib xws ntawm fuse lossis fuse qhuav, tsis yog cov tsis muaj cov yaj.
1. Melt tsis
Cov yaj muaj ob qho tsis muaj, cov ntaus nqi tam sim no thiab fusing tam sim no. Rated tam sim no yog hais txog tus nqi ntawm qhov tam sim no dhau ntawm fuse rau lub sijhawm ntev yam tsis muaj tawg. Qhov fuse tam sim no feem ntau yog ob zaug Rated tam sim no, feem ntau los ntawm Melt tam sim no yog 1.3 npaug ntawm qhov ntsuas (yuav tsum ua fused nyob rau hauv ntau dua ib teev; 1.6 zaug, yuav tsum ua phem rau hauv ib teev; Thaum lub fuse tam sim no tau mus txog, lub fuse yog tawg tom qab 30 ~ 40 vib nas this; Thaum 9 ~ 10 zaug qhov ntsuas nyob tam sim no tau mus txog, cov melt yuav tsum ua txhaum tam sim ntawd. Lub yaj muaj kev tiv thaiv tus yam ntxwv ntawm kev tiv thaiv hluav taws xob, qhov loj dua ntws los ntawm cov yaj tam sim no los ntawm lub sijhawm fuster.
2. VUAM COV YEEB YEEB
Lub fuse muaj peb qho tsis tau, uas yog ntsuas hluav taws xob voltage, ntsuas tam sim no thiab txiav tawm muaj peev xwm.
1) Cov hluav taws xob ntsuas yog npaj siab los ntawm lub kaum sab xis ntawm arc tua. Thaum lub zog ua haujlwm ntawm lub fuse yog ntau dua qhov ntsuas hluav taws xob, tej zaum yuav muaj kev phom sij tias lub arc tsis tuaj yeem tua thaum lub yaj tawg.
2) Cov raj ntsuas tam sim no ntawm lub raj molten yog tus nqi tam sim no txiav txim siab los ntawm cov tub txaij ntev, tab sis cov rated tam sim no ntawm molten raj tuaj yeem Tsis muaj ntau dua li qhov ntsuas ntawm cov raj ntawm molten.
3) Kev txiav tawm yog qhov muaj peev xwm yog qhov tseem ceeb tshaj plaws tam sim no uas tuaj yeem txiav tawm thaum lub fuse tau raug kaw los ntawm cov hluav taws xob ua txhaum ntawm qhov ntsuas hluav taws xob.
Tsib, tus ua haujlwm ntawm lub fuse
Cov txheej txheem fiming ntawm fuse yog ntxhib faib ua plaub theem:
1. Cov yaj yog hauv cov koob hauv Circuit Court, thiab cov thauj khoom tam sim no ntws los ntawm yaj. Vim tias cov cua sov ntawm qhov tam sim no yuav ua rau melt kub ntau, thaum muaj kev kub ntxhov tam sim no lossis luv luv dhau thiab ua kom sov melting kub. Qhov siab dua tam sim no, kev ceev nrawm dua.
2. Lub yaj yuav yaj thiab yaj rau hauv vapor tom qab ncav lub suab kub yaj. Qhov siab dua tam sim no, luv luv lub sijhawm tau melting.
3. Lub sijhawm melt melts, muaj ib qho kev sib txawv me me, muaj ib qho kev sib txawv me me, thiab cov khoom siv tam sim no cuam tshuam. Tab sis qhov sib txawv me me no tau tawg tam sim ntawd los ntawm Circuit Voltage, thiab lub arc hluav taws xob yog tsim tawm, uas nyob rau hauv lem txuas rau Circuit Court.
4. Tom qab Arc tshwm sim, yog tias lub zog txo nrog kev nthuav dav, tab sis nws yuav tsum cia siab rau kev tua hluav taws xob ntawm fuse thaum lub zog loj. Txhawm rau kom txo lub arc extinguishing lub sij hawm thiab nce qhov muaj peev xwm tawg, muaj peev xwm loj fuses yog nruab nrog lub arc extinguishing kev ntsuas. Qhov loj dua lub arc extinguishing muaj peev xwm yog, nrawm dua rau arc yog extinguished, thiab qhov loj dua lub luv luv hluav taws xob tam sim no tuaj yeem tawg los ntawm lub fuse.
Rau, xaiv cov fuse
1. Xaiv cov fuses nrog cov qib voltage raws li lub zog hluav taws xob voltage;
2. Xaiv cov fuses nrog kev sib raug kev sib raug zoo raws li qhov kev txhaum ntau tshaj plaws uas yuav tshwm sim hauv kev faib tawm;
3, lub fuse hauv lub cev muaj zog hluav taws xob rau cov kev tiv thaiv ncig ua ke, kom tsis txhob muaj ib lub cev muaj zog, rau ib lub cev muaj zog tam sim no, rau ib lub cev muaj tsawg dua 1.5 ~ 2.5 zaug cov rated tam sim no ntawm lub cev muaj zog; Rau ntau lub cev muaj ntau, tag nrho cov lative rated tam sim no yuav tsis muaj tsawg dua 1.5 ~ 2.5 zaug qhov muaj peev xwm muaj zog ntawm suav nrog cov thauj khoom tam sim no ntawm cov neeg tsav tsheb.
4. Rau kev tiv thaiv luv luv ntawm teeb pom kev zoo lossis lwm yam hluav taws xob, cov rated tam sim no ntawm me ntsis yuav tsum sib npaug los yog ib nyuag ntau dua li cov rated tam sim no ntawm lub nra.
5. Thaum siv fuses los tiv thaiv kab, fuses yuav tsum tau nruab rau txhua theem kab. Nws yog txwv tsis pub cuam tshuam rau ntawm txoj kab nruab nrab hauv ob-theem peb-theem tawg cov khoom tawg, uas tuaj yeem hlawv cov khoom siv hluav taws xob. Ntawm ib-theem kab muab los ntawm cov kab ke rau pej xeem, fuses yuav tsum tau nruab rau ntawm cov kab nruab nrab, tsis suav nrog tag nrho cov fuses ntawm daim phiaj.
6. Txhua theem ntawm cov fuses yuav tsum koom tes nrog lwm tus thaum siv, thiab cov rated tam sim no yog me dua li ntawd ntawm theem siab.
