1. Dab tsi yog cov yam ntxwv ntawm cov ntsia hlau fuse?
Lub tshuab fuse ntawm cov faus qeeb mentshis yog nruab nrog pob zeb xuab zeb, thiab lub yaj tau npaj nyob hauv nws. Thaum cov hmoov av yaj tag, cov arc tsuag rau ntawm cov xuab zeb quartz thiab nws qhov sib txawv tuaj yeem txias sai thiab tua. Txhawm rau ua kom yooj yim saib xyuas, ib qho kawg ntawm tus breaker yog nruab nrog xim taw tes. Cov xim sib txawv qhia cov dej sib txawv ntawm lub cev. Thaum lub cev tau tawg, cov xim taw tes jumps tawm qhia tias lub ntsws tau tawg. Nws ntsuas tam sim no yog 5 ~ 200A. Nws yog tsuas yog siv rau ceg nrog loj luv luv-xov tooj cua xob. Kev hluav taws xob hluav taws xob lossis qhov chaw nrog roj tawg.
Nws muaj lub hauv paus ntawm cov plooj (porcelain base), fuse tube, cov plooj (porcelain cap), thiab lwm yam Raws li qhia hauv daim duab 1 (a), muaj cov dav hlau thiab qis dua ntawm ob sab ntawm cov plooj (porcelain) coj los txuas rau hauv Circuit Court. Thaum xaim, txuas lub davhlau ya nyob twg mus rau lub zog hluav taws xob hauv txoj kev no, thaum hloov lub raj fuse, lub raj hloov pauv yog tub raj plooj nrog lub hau hlau kawg ntawm txhua qhov kawg, thiab cov fuse hauv fuse tube txuas nrog ob kawg lub kaus mom, raws li qhia hauv daim duab 1 (b), lub hau kawg ntawm lub taub fuse Muaj qhov taw qhia fuse nyob rau hauv qhov chaw, uas yuav hloov xim xim qhia thaum fuse raug phom. Ntawm qhov chaw ntawm lub ncov qaum ntawm cov plooj (cap) yog lub qhov muag pom kom pom tseeb kom pom lub qhov taw qhia fuse.
Thaum siv, muab lub ntsej muag fuse rau hauv qhov ntim cap, thiab tom qab ntawd ntsia hlau lub hau ntim mus rau hauv qhov chaw ntim cov pob zeb. Thaum txhim kho, them sai sai rau qhov
Qhov taw qhia fuse ntsib lub qhov rai saib ntawm tus khav theeb cap kom yooj yim saib.
2. Dab tsi yog cov yam ntxwv ntawm cov leeg ntim cov fuse RT?
Filled tube fuse yog hom fuse nrog qhov ntws tsawg, uas yog tsim los ntawm cov plooj (plooj plooj) fuse tub raj uas muaj cov xuab zeb quartz, kev tiv tauj thiab cov xim plated tooj liab ua kom yaj, raws li pom hauv daim duab 2. Cov khoom siv ua kua raj fuse raug ntsia rau ntawm qhov tshwj xeeb , xws li lub hauv paus nrog kev rho tawm riam hloov los yog lub hauv paus nrog kev fuse li cov riam cais tawm, thiab nws tau ua haujlwm los ntawm phau ntawv siv tshuab. Nws ntsuas tam sim no yog 50 ~ 1000A. Nws yog siv hauv kev xa hluav taws xob thiab kev faib khoom nrog AC 380V thiab hauv qab thiab loj luv luv-Circuit Court tam sim no. Nws siv raws li kev tiv thaiv luv-Circuit Court thiab overload tiv thaiv rau kab thiab khoom siv hluav taws xob. Nws yog tsuas yog siv rau hauv Circuit Court nrog loj luv luv-Circuit Court tam sim no los yog qhov chaw tau tawg ntawm Roj.
3. Dab tsi yog cov yam ntxwv ntawm qhov tsis tiav ntawm tubular fuse RM?
Lub kaw hluav taws xob ntawm lub raj tsis zoo fuse yog ua los ntawm cov khoom siv fibrous. Cov yaj siv yog ua cov zinc alloy daim nrog cov ntu sib faib. Raws li pom hauv daim duab 3, thaum lub hmoov yaj yog yaj, ib feem ntawm cov khoom siv ntawm cov fibrous yog ua los ntawm cov cua kub. Nws yog decomposed los tsim cov pa roj ua kom lub siab, uas ceev tua cov roj. Nws muaj cov yam ntxwv ntawm cov qauv yooj yim, tiv thaiv kev ua tau zoo, thiab siv tau yooj yim. Feem ntau, nws yog siv ua ke nrog riam txuas txhawm rau txhawm rau fuse riam hloov.
4. Dab tsi yog cov yam ntxwv ntawm kev muab tub lim Zeng-hom ceev fuse RS?
Filled kaw raj hom fuse ceev yog lub fuse ua yeeb yam, tsim ntawm fuse raj, tiv tauj lub hauv paus, qhov taw qhia kev txiav txim siab thiab yaj, raws li muaj nyob hauv daim duab 48. Lub suab yaj yog nyob rau hauv daim ntawv ntawm nqaim hla ntawm nyiaj lossis lub mesh. Qhov yaj yog rau kev siv ib zaug thiab tsis tuaj yeem hloov nws tus kheej. Vim tias qhov kev txiav txim nrawm nrawm, feem ntau siv rau kev tiv thaiv semiconductor rectifier Cheebtsam.
5. Dab tsi yog kev tiv thaiv tus yam ntxwv ntawm kev fuse?
Teb: Qhov tiv thaiv tus yam ntxwv ntawm kev fuse hais txog cov yam ntxwv ntawm lub yaj yaj. Feem ntau, txoj kev tam sim no dhau ntawm yaj
Nws yuav siv sij hawm kom tuab. Cov yam ntxwv no yog lub sijhawm tsis hloov. Muaj tsawg kawg melting tam sim no tus nqi nyob rau hauv kev tiv thaiv cov yam ntxwv ntawm lub fuse. Tsuas yog thaum tam sim no mus txog ntawm lub yaj yog ntau dua lossis sib npaug nrog tus nqi no, cov yaj yuav yaj tau nyob rau ib lub sijhawm. Raws li qhov yuav tsum tau ua, cov rated tam sim no ntawm yaj yuav tsum tsawg dua qhov tsawg kawg melting tam sim no. Qhov sib piv ntawm qhov ntsuas tam sim no ntawm tus ntsuas hluav taws xob rau qhov hloov tsawg kawg tam sim no yog hu ua melting coefficient [formula], qhov coefficient yog qhov rhiab heev ntawm qhov fuse los tiv thaiv lub teeb liab me dhau, nws tus nqi feem ntau yog nyob ntawm cov khoom siv thiab cov qauv ntawm yaj thiab nws ua hauj lwm kub. Qhov tsawg dua tus nqi los ntawm kev tiv thaiv overload yog, qhov ntau dua haum me me ntau.
Lub sijhawm fuse ntawm lub fuse yog sib npaug rau qhov suav ntawm lub sijhawm melting thiab lub sijhawm sib cav. Txij li lub sijhawm arcing yog luv heev thiab tuaj yeem tsis quav ntsej, lub ntsej muag melting yog tus ua ntej-arc tam sim no-lub sijhawm tus yam ntxwv ntawm lub fuse.
Txhawm rau kom ntseeg tau tias lub fuse tsis tawg raws li nws cov theem tam sim no, 10% -20% pawg xov xwm yuam kev feem ntau sab laug ntawm nws cov yam ntxwv nkhaus, uas yog, 10% -20% npoo yog sab laug thaum xaiv.
6. Dab tsi yog cov yam ntxwv ntawm kev qeeb qeeb?
Teb: Lub fuse qeeb tseem hu ua lub sijhawm ncua sij hawm fuse, raws li qhia hauv daim duab 5. Nws lub sijhawm ncua sijhawm hais tias lub Circuit Court tseem nyob thaum muaj qhov tsis cuam tshuam rau cov mem tes tam sim no thiab tuaj yeem muab kev tiv thaiv ntev dhau. Qhov tam sim no ntawm qee qhov kev sib luag ntawm lub sij hawm hloov hluav taws xob muaj ntau dua li ob peb zaug ntawm qhov haujlwm niaj hnub. Txawm hais tias tam sim no tus nqi tam sim no siab heev, nws tshwm sim rau ib lub sijhawm luv. Peb hu nws cov mem tes tam sim no lossis kab tam sim no lossis nrov tam sim no. Cov fuses zoo tib yam tsis tuaj yeem tiv thaiv qhov tam sim no. Yog tias qhov fuse zoo siv hauv qhov hauv Circuit Court, nws yuav tsis tuaj yeem pib ua qub; yog tias kev siv fuse loj dua, nws yuav tsis muaj kev tiv thaiv thaum lub sijhawm Circuit Court overloaded; Cov yaj ntawm lub sijhawm ncua sij hawm fuse raug tshwj xeeb ua. Nws muaj cov haujlwm ntawm kev nqus lub zog. Hloov kho cov nqi ntawm lub zog hluav taws xob tuaj yeem ua kom nws tsis tsuas tuaj yeem tiv thaiv qhov cuam tshuam tam sim no tab sis kuj muab kev tiv thaiv tiv thaiv ntau dhau. Cov qauv muaj cov kev cai hais txog ncua cov yam ntxwv, yog tias tus qauv stipulates. Cov yam ntxwv ua tsis tau raws li qhov yuav tsum tau ua, koj tuaj yeem tiv toj rau cov chaw tsim khoom tsim tshwj xeeb.
