Hauv kev faib khoom siv nyiaj siv ua haujlwm, qhov txuas fuse yog ib qho ntawm cov khoom uas tsis tau txais kev saib xyuas ntau txog thaum muaj qee yam tsis raug. Nws zaum ntsiag to hauv qhov kev txiav tawm, thiab lub sijhawm muaj kev tshwm sim overcurrent hits kab, nws melts thiab cuam tshuam qhov txhaum ua ntej muaj dab tsi tshwm sim loj dua. Lub fuse txuas yog, nyob rau hauv qhov tseeb heev, kab kawg ntawm kev tiv thaiv rau transformers thiab kab seem. Tab sis tsis yog txhua qhov kev sib txuas fuse coj zoo ib yam. Ntawm cov kev faib khoom siv dav tshaj plaws hauv North American thiab thoob ntiaj teb kev faib tawm yog Hom K thiab Hom T, thiab kev nkag siab qhov sib txawv ntawm lawv yog qhov tseem ceeb rau txhua tus neeg koom nrog hauv kev tsim hluav taws xob tiv thaiv.
Kev faib tawm hauv qab Cov Ntawv
Cov qauv K thiab T yog los ntawm ANSI / IEEE cov qauv, thiab lawv piav qhia seb txhua qhov txuas fuse teb li cas rau cov xwm txheej dhau sijhawm. Tus cwj pwm no raug ntes nyob rau lub sijhawm- tus yam ntxwv nkhaus tam sim no, ib zaj dab neeg ntawm qhov ntev npaum li cas lub fuse yuav yaj ntawm ntau qhov ntau ntawm nws qhov ntsuas tam sim no. Cov duab ntawm qhov nkhaus no yog dab tsi engineers cia siab rau thaum tsim cov phiaj xwm kev tiv thaiv, vim tias kev sib koom tes ntawm cov khoom siv yog nyob ntawm txhua qhov kev ua haujlwm ntawm lub sijhawm thiab nyob rau hauv raws li txoj cai.
Cov metric tseem ceeb siv los txhais cov hom no yog hu ua qhov sib piv ceev, xam raws li qhov piv ntawm cov melting tam sim no ntawm 0.1 vib nas this mus rau lub melting tam sim no ntawm 300 vib nas this. Rau Hom K, qhov sib piv no poob ntawm 6 thiab 8. Rau Hom T, nws ntog ntawm 10 thiab 13. Qhov sib txawv ntawm qhov sib piv yog qhov sib cais ceev fuse los ntawm ib qho qeeb, thiab nws muaj qhov cuam tshuam loj rau txhua hom coj li cas hauv thaj teb.
Hom K: Fast Fuse
Hom Kfuse txuas react sai sai thaum muaj qhov tseem ceeb overcurrent tshwm sim. Vim tias qhov sib piv ceev qis dua, lub fuse mus txog nws qhov melting point sai dua ntawm ib qho kev ua txhaum cai. Qhov no ua rau Hom K zoo haum rau cov ntawv thov uas qhov kev ua txhaum sai sai yog qhov tseem ceeb, tshwj xeeb tshaj yog qhov txwv tsis pub thermal thiab kev ntxhov siab ntawm cov cuab yeej nyob ze yog qhov tseem ceeb.
Lateral kais kab, capacitor bank tiv thaiv, thiab kab kab nyob ze rau lub substation yog cov tsev nyob rau hom K fuses. Nyob rau hauv cov chaw no, qhov txhaum tam sim no feem ntau yuav siab thiab tus engineer lub hom phiaj yog kom tshem tawm qhov yuam kev sai, txo lub zog tso tawm ntawm qhov txhaum thiab txo qhov kev pheej hmoo ntawm kev puas tsuaj los yog cov khoom siv tsis ua haujlwm. Hom K fuses kuj tseem muaj nuj nqis hauv cov tshuab uas muaj kev sib koom tes nrog cov neeg siv dej ntws rov qab kom nruj thiab txhua millisecond ntawm lub sijhawm teb tseem ceeb.
Kev lag luam tawm yog txwv kam rau ua rau cov caij nyoog dhau los. Yog hais tias lub load ntawm lub tiv thaiv Circuit Court rub ib tug surge ntawm tam sim no luv luv, txawm rau ib tug tag nrho vim li cas, hom K fuse yuav txhais hais tias surge raws li ib tug txhaum thiab qhib lub Circuit Court. Qhov no yog qhov teeb meem kev ua haujlwm tsis zoo, thiab nws yog ib qho ntawm cov laj thawj tseem ceeb ntawm Hom T muaj.

Hom T: Slow Fuse
Hom Tfuse txuas tau tsim nrog qhov sib piv ceev dua, uas txhais tau hais tias lawv tuaj yeem caij dhau ib ntus overcurrent yam tsis tau qhib. Lawv siv sijhawm ntev dua kom yaj, thiab lub sijhawm ntxiv yog qhov ua rau lawv muaj txiaj ntsig zoo hauv cov ntawv thov uas cov dej ntws tawm yog ib feem ntawm kev ua haujlwm ib txwm muaj.
Qhov piv txwv classic tshaj plaws yog kev tiv thaiv transformer. Thaum lub tshuab hluav taws xob faib hluav taws xob muaj zog, nws rub lub zog loj magnetizing inrush tam sim no rau lub sijhawm luv luv, qee zaum ncav cuag rau rau rau kaum npaug ntawm qhov ntsuas tam sim no, txawm tias tsis muaj dab tsi tiag tiag nrog lub kaw lus. Lub fuse ceev nrooj ntsia rau ntawm lub tshuab hloov pauv tuaj yeem qhib rau qhov kev tshwm sim inrush, ua rau muaj kev cuam tshuam uas yuav tsum muaj cov neeg ua haujlwm teb, hloov lub fuse, thiab cov neeg siv khoom tos hauv qhov tsaus ntuj tsis muaj laj thawj zoo. Hom T fuses zam cov kev hloov pauv hloov pauv thaum tseem tab tom tshem tawm cov kev ua txhaum tiag tiag. Lub cev muaj zog loads ntawm thaj chaw ua liaj ua teb lossis kev lag luam coj zoo ib yam, kos cov dej pib hnyav ua ntej ua haujlwm ua haujlwm.
Qhov twg tej yam tau txais ntau nuanced yog nyob rau hauv qhov chaw ntawm lub zog yuam kev cia- los ntawm. Vim tias Hom T fuses siv sijhawm ntev dua los ua haujlwm, lawv tso cai rau lub zog ua txhaum ntau dhau mus rau hauv Circuit Court ua ntej cuam tshuam nws. Nyob rau hauv ib puag ncig siab tam sim no, lub zog ntxiv tuaj yeem ua rau muaj kev puas tsuaj ntau dua rau cov neeg siv hluav taws xob, cables, thiab cov khoom siv nyob ze. Slower tsis tau txais kev nyab xeeb dua. Nws tsuas yog ua lag luam ib qho kev pheej hmoo rau lwm tus, thiab qhov nyiaj tshuav yog nyob ntawm qhov tshwj xeeb.

Kev Sib Koom Tes: Tus Tsav Tsheb Txiav Txim Siab
Kev xaiv ntawm Hom K thiab Hom T thaum kawg yog ib qho kev tawm dag zog hauv kev tiv thaiv kev sib koom tes. Lub hauv paus ntsiab lus yog tias cov cuab yeej ze tshaj plaws rau qhov txhaum yuav tsum ua haujlwm ua ntej, cais tsuas yog qhov tsawg tshaj plaws ntawm lub network. Yog tias lub fuse sab nraud qeeb dhau lawm, nws yuav tso cai rau lub tshuab hluav taws xob rov qab los yog lub tshuab hluav taws xob ua haujlwm hloov, txiav lub zog mus rau thaj tsam loj dua. Yog tias nws nrawm dhau, nws yuav ua rau lub sijhawm luv luv thiab ua rau muaj kev tawm tsam uas yuav tsum tsis txhob tshwm sim.
Cov kws ua haujlwm npaj lub sijhawm-khoov tam sim no rau txhua lub cuab yeej tiv thaiv hauv lub cev thiab xyuas seb cov kab nkhaus puas sib cais kom huv si thoob plaws tag nrho cov kev ua txhaum tam sim no. Lub tswv yim sib koom ua ke tsim kom muaj qhov pom tseeb: lub fuse sab nraud pom qhov txhaum ua ntej lub feeder recloser ua, tus recloser pom nws ua ntej lub substation breaker, thiab hais txog. Hom K thiab Hom T fuses nyob hauv ntau txoj haujlwm hauv qhov cascade nyob ntawm seb lawv tau nruab thiab tiv thaiv dab tsi.
Cov kev faib tawm nyob deb nroog, qhov uas xob laim - cuam tshuam cov kev cuam tshuam ntau zaus thiab kev ua liaj ua teb lub cev muaj zog muaj ntau, feem ntau nyiam hom T ntawm transformer cutouts. Dense urban systems with high available fault currents and tight conductor spacing may lean toward Type K to keep fault clearing times short. Nyob rau hauv lub qhov dej -tsim feeder, nws yog ib txwm ib txwm nrhiav tau ob hom nyob rau hauv kev siv ntawm txawv cov ntsiab lus nyob rau hauv tib txoj kab.
Kev tsim kho thiab kev ua tau zoo
Ob hom K thiab Hom T fuse txuas sib koom ua ke kev tsim kho lub cev zoo sib xws. Cov khoom fusible, feem ntau yog ua los ntawm cov nyiaj los yog cov nyiaj alloy, yog nyob rau hauv ib lub raj fiberglass los yog fiberglass raj. Qhov txawv ntawm ib qho los ntawm lwm qhov yog qhov tseeb geometry ntawm lub ntsiab lus: cov ntawv sau, hla - ntu, thiab cov ntsiab lus seem uas tswj raws nraim qhov twg thiab ceev npaum li cas nws melts. Lub fuse uas sib koom ua ke zoo kawg nkaus hauv txoj kev xav tsuas yog ua raws li qhov xav tau hauv kev coj ua yog tias kev tsim khoom zoo sib xws. Qhov kev kam rau siab, cov khoom siv purity, thiab cov txheej txheem tswj txhua qhov cuam tshuam ncaj qha rau lub sijhawm- tus yam ntxwv tam sim no, thiab txhua qhov sib txawv ntawm qhov tshwj xeeb tuaj yeem hloov qhov nkhaus txaus los ua txhaum kev sib koom tes hauv thaj chaw.
Qhov twg los Tau Hom K thiab Hom T Fuse Txuas
Rau cov pab pawg neeg yuav khoom thiab cov engineers uas xav tau kev sib txuas fuse txhim khu kev qha los ntawm cov khoom pov thawj, Victory Electric Power Equipment Co., Ltd. yog cov chaw tsim khoom tsim nyog xav txog. Founded hauv 1998 thiab headquartered nyob rau hauv Lishui City, Zhejiang Province, yeej tau tsim tis hardware rau ntau tshaj ob xyoo lawm thiab xa mus rau ntau tshaj 50 lub teb chaws thoob plaws South America, North America, Africa, thiab Asia. Lawv cov fuse txuas ntau yam suav nrog Hom K thiab Hom T hla cov qauv ntsuas tam sim no los ntawm 6A txog 150A, nrog rau cov ntsuas tam sim no ua raws li ANSI specifications. Lub tuam txhab tuav ISO9001 ntawv pov thawj thiab ua haujlwm ntau tshaj 60,000 square meters, ua tiav nrog nws tus kheej R & D department thiab kuaj kuaj.
Txawm hais tias koj tab tom qhia txog kev sib txuas fuse rau ib txoj haujlwm tshiab nyiaj siv ua haujlwm lossis hloov cov kev laus txiav tawm ntawm cov khoom noj uas twb muaj lawm, Victory's Type K thiab Type T cov khoom muaj rau kev nug ncaj qha.Tiv tauj pebmus saib tag nrho ntau yam thiab thov ib nqe lus.
