fuses tuaj yeem muab faib ua high-voltage fuses thiab low-voltage fuses raws li qhov voltage siv. Yog xav paub ntxiv txog qhov tseeb fuse kev lag luam kev lag luam tsom xam, thov mus saib Daim Ntawv Qhia Txog Kev Tshawb Fawb ntawm Tuam Tshoj Fuse Kev Lag Luam Kev Lag Luam Kev Lag Luam thiab Kev Lag Luam Kev Lag Luam Kev Lag Luam hauv 2016-2021 tawm los ntawm Tuam Tshoj Report Hall.
Raws li cov khoom tiv thaiv, nws tuaj yeem muab faib ua fuses rau kev tiv thaiv kev hloov pauv thiab cov khoom siv hluav taws xob dav dav, fuses rau kev tiv thaiv Voltage transformer, fuses rau kev tiv thaiv hluav taws xob capacitors, fuses tiv thaiv semiconductor ntsiab, fuses tiv thaiv motors thiab fuses tiv thaiv cov khoom siv hauv tsev. Raws li cov qauv, nws tuaj yeem muab faib ua hom qhib, semi kaw hom, raj hom, thiab dav hlau hom fuses.
Qhov qhib hom fuse muaj cov qauv yooj yim, thiab cov yaj yog kiag li raug rau huab cua. Nws tau txais kev txhawb nqa los ntawm cov kab porcelain thiab tsis muaj kev txhawb nqa, ua rau nws tsim nyog rau kev siv sab nraum zoov tsawg. Thaum rhuav tshem tam sim no, ntau lub suab thiab lub teeb tsim tawm hauv qhov chaw.
Lub yaj ntawm lub semi-enclosed fuse yog ntsia rau ntawm lub plooj (porcelain thav duab) thiab muab tso rau hauv ib lub thawv porcelain nrog hlau sockets ntawm ob qho kawg, tsim nyog rau kev siv hluav taws xob tsawg hauv tsev. Thaum rhuav tshem tam sim no, lub suab thiab lub teeb tsim tau raug thaiv los ntawm lub thawv plooj (porcelain box).
Lub yaj ntawm tubular fuse yog ntsia rau hauv lub cev fuse. Tom qab ntawd ntxig nws rau hauv qhov kev txhawb nqa lossis txuas ncaj qha rau hauv Circuit Court rau kev siv. Lub fuse yog ib lub raj kaw tag nrho nrog lub hau hlau los yog sib cuag riam ntawm ob qho kawg. Yog hais tias lub rwb thaiv tsev ntawm hom fuse no tau ntim nrog quartz xuab zeb, nws muaj qhov 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 tshuab nqus tsev tau kos rau hauv cov yeeb nkab, nws yog hu ua lub tshuab nqus tsev fuse. Yog tias lub raj ntim nrog SF6 roj, nws yog hu ua SF6 fuse, uas yog lub hom phiaj los txhim kho kev ua haujlwm ntawm kev tua hluav taws. Vim tias qhov kev ua haujlwm zoo ntawm cov quartz xuab zeb, lub tshuab nqus tsev, thiab SF6 roj, hom fuse no tsis yog tsuas yog tsim rau cov hluav taws xob tsawg tab sis kuj muaj hluav taws xob siab.
Lub dav hlau hom fuses yog cov raj rwb thaiv tsev ua los ntawm cov khoom siv roj ua cov khoom uas muaj cov yaj. Cov khoom siv roj av tuaj yeem ua los ntawm hluav taws xob dawb cardboard lossis cov khoom siv iav organic. Thaum lub voj voog luv luv dhau los ntawm cov yaj, cov yaj tam sim ntawd melts thiab tsim ib qho arc. Qhov kub-kub arc sai sai decomposes cov khoom siv roj ua kom tsim tau cov pa roj ntau ntau, uas txau cov roj ionized nrog ib qho kev them nqi ntawm ob qho kawg ntawm cov yeeb nkab, emitting lub suab zoo thiab lub teeb. Thaum AC tam sim no dhau xoom, lub arc raug tua thiab tam sim no tawg. Insulating raj feem ntau yog ntsia rau ntawm ib qho insulating bracket los tsim tag nrho cov fuse. Qee lub sij hawm qhov kawg ntawm cov yeeb nkab rwb thaiv tsev yog ua rau hauv hom txav tau, uas tam sim ntawd disconnects thiab tee tom qab tawg tam sim no. Hom dav hlau fuse no feem ntau hu ua fuse poob. Feem ntau haum rau kev siv sab nraum zoov nrog voltages siab dua 6 kV.
Tsis tas li ntawd, fuses tseem tuaj yeem muab faib ua cov hom phiaj dav dav, cov fuses thaub qab, thiab ntau yam fuses raws li qhov kev sib tsoo tam sim no. Qhov kev sib tsoo tam sim no ntawm lub hom phiaj dav dav fuses hais txog qhov ntau ntawm cov khoom siv tam sim no tshaj li 1.6-2 npaug ntawm qhov ntsuas tam sim no mus rau qhov siab tshaj plaws tawg tam sim no. Hom fuse no tsuas 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 tshaj 4-7 npaug ntawm qhov ntsuas tam sim no mus rau qhov siab tshaj plaws tawg tam sim no. Hom fuse no feem ntau yog siv nyob rau hauv series nrog ib tug contactor, uas ua tiav kev tiv thaiv tawg thaum lub overload tam sim no tsawg dua 4-7 npaug ntawm qhov ntsuas tam sim no. Feem ntau yog siv los tiv thaiv hluav taws xob motors.
Nrog rau cov kev xav tau ntawm kev tsim kho, tshwj xeeb fuses haum rau ntau yam kev xav tau kuj tau tsim, xws li hluav taws xob fuses, thermal fuses, thiab nws tus kheej reset fuses.
