Txheej txheem cej luam
Qhov poob fuse thiab load hloov fuse yog cov khoom siv tiv thaiv hluav taws xob sab nraum zoov.Lawv txuas nrog cov khoom xa tuaj lossis cov kab xa tawm ntawm cov khoom xa tawm.Cov no yog siv los tiv thaiv transformers los yog kab los ntawm luv luv Circuit Court, overload thiab hloov tam sim no.Qhov poob fuse muaj ib qho hluav taws xob bracket thiab lub raj fuse.Cov kev sib cuag zoo li qub yog tsau rau ntawm ob sab ntawm lub insulator bracket, thiab cov kev sib tiv tauj tau raug ntsia rau ntawm ob qho kawg ntawm lub raj fuse.Nyob rau hauv lub fuse tube yog ib tug hluav taws hose.Sab nrauv yog ua los ntawm phenolic composite ntawv raj lossis epoxy iav.Lub load hloov fuse muab kev pabcuam txuas ntxiv thiab arc extinguishing chamber kaw rau qhib / kaw lub sijhawm tam sim no.
Thaum lub sijhawm ua haujlwm ib txwm, lub fuse raug rub mus rau qhov chaw kaw.Nyob rau hauv qhov teeb meem tam sim no, lub fuse txuas melts thiab tsim ib qho arc.Qhov no yog qhov xwm txheej ntawm arc extinguishing chamber.Qhov no ua rau muaj kev kub siab hauv lub raj thiab ua rau lub raj cais tawm ntawm cov neeg sib cuag.Thaum lub fuse melts, lub zog ntawm cov neeg sib cuag yuav so.Lub Circuit Court breaker tam sim no nyob rau hauv txoj hauj lwm qhib thiab tus neeg teb xov tooj yuav tsum tau tua tam sim no.Tom qab ntawd cov kev sib tiv tauj tuaj yeem rub tau los ntawm kev siv insulated levers.Kev sib cuag tseem ceeb thiab kev pabcuam pabcuam txuas nrog.
tswj
(1) Txhawm rau ua kom lub fuse ua haujlwm zoo dua thiab muaj kev nyab xeeb, ntxiv rau kev xaiv nruj me ntsis cov khoom tsim nyog thiab cov khoom siv (nrog rau cov khoom fusible) uas tsim los ntawm cov tuam txhab tsim khoom raws li cov cai ntawm cov cai, cov teeb meem hauv qab no yuav tsum tau them nyiaj tshwj xeeb. rau hauv kev khiav hauj lwm thiab kev tswj xyuas:
① Txheeb xyuas seb qhov ntsuas tam sim no ntawm lub fuse puas phim cov yaj thiab thauj khoom tam sim no kom raug.Yog tias qhov sib piv tsis raug, nws yuav tsum tau kho.
② Txhua qhov kev ua haujlwm ntawm lub fuse yuav tsum tau ceev faj thiab ceev faj, tsis txhob saib xyuas, tshwj xeeb tshaj yog kev kaw haujlwm.Cov kev sib cuag dynamic thiab zoo li qub yuav tsum muaj kev sib cuag zoo.
③ Cov txheej txheem yaj yuav tsum tau siv rau hauv cov yeeb nkab yaj.Nws yog txwv tsis pub siv tooj liab hlau thiab txhuas hlau es tsis txhob yaj, thiab nws tsis raug tso cai siv tooj liab hlau, txhuas hlau thiab hlau hlau los khi kev sib cuag.
④ Rau cov fuses tshiab los yog hloov tshiab, cov txheej txheem txais yuav tsum tau ua nruj me ntsis, thiab cov kev cai zoo ntawm cov kev cai yuav tsum tau ua.Lub kaum sab xis ntawm lub fuse tube yuav tsum ncav cuag li 25 °.
⑤ Lub fused yaj yuav tsum tau hloov nrog ib qho tshiab ntawm tib cov lus qhia.Nws tsis raug tso cai los txuas lub fused yaj thiab muab tso rau hauv lub raj yaj rau kev siv ntxiv.
⑥ Lub fuse yuav tsum tau tshuaj xyuas tsis tu ncua, tsawg kawg ib hlis ib zaug thaum hmo ntuj, txhawm rau xyuas seb puas muaj cov pa paug tawm thiab kev sib cuag tsis zoo.Yog tias muaj paug tawm, yuav muaj lub suab nrov nrov, uas yuav tsum tau ua kom sai li sai tau.
(2) Kev tshuaj xyuas hauv qab no yuav tsum tau ua rau cov fuses thaum lub caij nplooj ntoos hlav tshuaj xyuas thiab kev saib xyuas tsis raug:
① Txawm hais tias kev sib cuag ntawm kev sib cuag zoo li qub thiab txav mus los yog sib xws, nruj thiab tsis zoo, thiab seb puas muaj qhov kub hnyiab.
② Txawm hais tias qhov sib hloov ntawm lub fuse yog hloov tau, xeb, hloov tsis tau, thiab lwm yam, seb cov khoom puas puas, thiab seb lub caij nplooj ntoos hlav puas xeb.
③ Txawm tias lub yaj nws tus kheej puas lawm los yog tsis, thiab seb puas muaj cua sov elongation ntau dhau thiab ua tsis muaj zog tom qab lub hwj chim mus ntev.
④ Seb lub arc suppression tube rau roj ntau lawm nyob rau hauv lub melting tube yog hlawv, puas thiab deformed tom qab raug rau lub hnub thiab los nag, thiab seb qhov ntev yog luv luv tom qab ntau yam kev ua.
⑤ Ntxuav lub rwb thaiv tsev thiab xyuas seb puas muaj kev puas tsuaj, tawg lossis paug tawm.Tom qab tshem tawm cov coj mus rau sab sauv thiab sab qis, siv lub 2500V megger los ntsuas cov rwb thaiv tsev tiv thaiv, uas yuav tsum siab tshaj 300M Ω.
⑥ Txheeb xyuas seb qhov txuas sab sauv thiab sab qis ntawm lub fuse puas xoob, tawm los yog overheated.
Qhov tsis xws luag hauv cov khoom saum toj no yuav tsum tau ua tib zoo kho thiab ua haujlwm.
Melting tube qauv:
Lub fuse yog ua los ntawm flberglsaa, uas yog noo noo thiab corrosion resistant.
Fuse Base:
Lub hauv paus khoom yog embedded nrog mechanical lug thiab insulators.Cov hlau pas nrig mechanism yog ntsia nrog cov khoom nplaum tshwj xeeb thiab cov rwb thaiv tsev, uas tuaj yeem tiv taus luv luv Circuit Court tam sim no tig rau lub zog.
Moisture-proof fuse tsis muaj npuas, tsis muaj deformation, tsis qhib Circuit Court, muaj peev xwm loj, tiv thaiv ultraviolet, lub neej ntev, superior hluav taws xob zog, dielectric zog thiab zoo heev mechanical rigidity thiab mob siab rau.
Tag nrho cov mechanism yog nruab nrab, yooj yim rau nruab, nyab xeeb thiab txhim khu kev qha.
