fuses tuaj yeem muab faib ua high-voltage fuses thiab low-voltage fuses raws li qhov voltage siv. Raws li cov khoom tiv thaiv, nws tuaj yeem muab faib ua fuses rau kev tiv thaiv transformers thiab cov khoom siv hluav taws xob dav dav, fuses rau kev tiv thaiv hluav taws xob transformers, fuses tiv thaiv lub hwj chim capacitors, fuses tiv thaiv semiconductor Cheebtsam, fuses tiv thaiv motors thiab fuses tiv thaiv cov khoom siv hauv tsev. fuses, thiab lwm yam raws li cov qauv, nws tuaj yeem muab faib ua hom qhib, semi-kaw hom, tubular hom thiab tshuaj tsuag hom fuse.
Qhov qhib fuse muaj cov qauv yooj yim, cov yaj yog tag nrho raug rau saum huab cua, thiab tau txais kev txhawb nqa los ntawm cov porcelain kem tsis muaj kev txhawb nqa, uas yog tsim rau kev siv hluav taws xob sab nraum zoov. Thaum qhov tam sim no cuam tshuam, lub suab loj thiab lub teeb raug tsim tawm hauv qhov chaw.
Lub yaj ntawm lub semi-enclosed fuse yog ntsia rau ntawm ib tug porcelain thav duab thiab muab tso rau hauv lub porcelain lub thawv nrog hlau sockets ntawm ob hnub, uas yog haum rau tsawg-voltage siv sab hauv tsev. Thaum rhuav tshem tam sim no, lub suab thiab lub teeb tsim tau raug thaiv los ntawm lub thawv plooj (porcelain box).
Cov yaj ntawm tubular fuse yog muaj nyob rau hauv lub cev fuse. Tom qab ntawd ntsaws rau hauv qhov chaw muag khoom lossis txuas ncaj qha rau hauv Circuit Court rau siv. Qhov txuas fuse yog ib lub raj kaw tag nrho nrog lub hau hlau lossis cov hniav sib txuas ntawm ob qho kawg. Yog hais tias lub insulating raj ntawm no fuse yog ntim nrog quartz xuab zeb, nws yuav muaj kev txwv tam sim no thaum tawg tam sim no, uas tuaj yeem txhim kho lub peev xwm tawg tau zoo, yog li nws tseem hu ua lub peev xwm tawg siab. Yog tias lub raj raug tshem tawm, nws yog hu ua lub tshuab nqus tsev fuse. Yog hais tias lub raj yog ntim nrog SF6 roj, nws yog hu ua SF6 fuse, thiab nws lub hom phiaj yog los txhim kho lub arc extinguishing kev ua tau zoo. Txij li thaum quartz xuab zeb, lub tshuab nqus tsev thiab SF6 roj muaj cov khoom zoo insulating, cov fuse no tsis yog tsuas yog tsim rau cov hluav taws xob tsawg tab sis kuj muaj hluav taws xob siab.
Lub dav hlau fuses muaj cov yaj nyob rau hauv ib lub raj insulating ua los ntawm cov khoom siv roj tsim. Cov khoom siv hluav taws xob tsim hluav taws xob tuaj yeem ua los ntawm hluav taws xob los tiv thaiv dawb cardboard lossis plexiglass khoom. Thaum lub caij luv luv tam sim no dhau los ntawm cov yaj, cov yaj yog tam sim ntawd fused los tsim ib qho arc, thiab qhov kub-kub arc ua rau cov khoom siv roj ua kom sai decompose los tsim cov roj ntau ntau, yog li ntawd. cov roj ionized yog ejected ntawm ob kawg ntawm lub raj nrog ib tug arc, emitting zoo suab thiab lub teeb, Thiab thaum lub AC tam sim no hla xoom, lub arc yog extinguished thiab tam sim no cuam tshuam. Lub raj insulating feem ntau yog mounted ntawm ib qho insulating bracket los tsim tag nrho cov fuse. Qee zaum sab sauv kawg ntawm lub raj insulating yog ua txav tau, thiab tom qab tawg tam sim no, nws raug txiav thiab poob. Hom dav hlau fuse no feem ntau hu ua fuse poob. Feem ntau haum rau sab nraum zoov qhov twg qhov voltage siab tshaj 6 kV.
Tsis tas li ntawd, fuses tuaj yeem muab faib ua cov fuses dav dav, cov fuses thaub qab thiab cov fuses tag nrho raws li qhov tawg tam sim no. Kev tawg tam sim no ntau yam ntawm lub hom phiaj fuses yog hais txog qhov ntau ntawm cov khoom siv tam sim no ntau dua 1.6 txog 2 npaug ntawm qhov ntsuas tam sim no mus rau qhov siab tshaj plaws tawg tam sim no. Xws li fuses feem ntau yog siv los tiv thaiv lub zog transformers thiab cov khoom siv hluav taws xob. Qhov kev tawg tam sim no ntawm cov fuse thaub qab yog hais txog qhov ntau ntawm cov khoom siv tam sim no ntau dua 4 txog 7 npaug ntawm qhov ntsuas tam sim no mus rau qhov siab tshaj plaws tawg tam sim no. Qhov no fuse feem ntau yog siv nyob rau hauv series nrog tus contactor. Thaum lub overload tam sim no tsawg dua 4 mus rau 7 npaug ntawm qhov ntsuas tam sim no, tus contactor yog siv los paub txog kev tiv thaiv tawg. Feem ntau yog siv los tiv thaiv lub cev muaj zog.
Nrog rau cov kev xav tau ntawm kev tsim kho, tshwj xeeb fuses haum rau ntau yam yuav tsum tau tsim, xws li hluav taws xob fuses, thermal fuses thiab resettable fuses.
