FIMES PROUNDON DEVICES los ntawm Hluav Taws Xob Tam Sim No thiab Tiv Thaiv Kev Puas Tsuaj Loj Los Ntawm Kev Ua Tsis Txaus. Yog li ntawd, txhua fuse muaj qhov kev ntaus nqi, thiab lub fuse yuav tshuab thaum qhov tam sim no tshaj qhov ntaus nqi. Thaum ib qho tam sim no tau thov rau lub fuse uas yog nruab nrab ntawm cov peev txheej tam sim no thiab cov ntsuas hluav taws xob tau ua haujlwm tau teev tseg, lub fuse yuav tsum ua haujlwm zoo txaus siab thiab tsis muaj kev cuam tshuam ib puag ncig zoo txaus siab.
Qhov kev ua txhaum kev txhaum tam sim no ntawm Circuit uas lub fuse nyob yuav tsum tau nruab yuav tsum yog tsawg dua li cov ntsuas hluav taws xob muaj peev xwm teev hauv tus qauv. Txwv tsis pub, thaum lub txhaum yuav txuas ntxiv mus ya, taws, hlawv cov fuse, yaj ua ke nrog kev tiv tauj, thiab cov fuse tau tsis tuaj yeem lees paub. Ntawm chav kawm, qhov muaj peev xwm tawg ntawm cov tsis tau muaj txiaj ntsig tsis tau raws li cov cai tau hais tseg hauv tus qauv, thiab kev siv cov kev phom sij tib yam yuav tshwm sim.
Ntxiv rau cov fuser resistors, tseem muaj cov fuses genus, thermal fuses thiab tus kheej txoj kev hloov kho tus kheej. Lub ntsiab tiv thaiv yog feem ntau txuas rau hauv Circuit Court, nws nyob rau hauv lub voj voog ntawm dhau tam sim no, tshaj lwm yam kev tsis txaus siab thiab ua si qhov kev tiv thaiv tam sim no, tuaj yeem tiv thaiv kev nthuav dav ntxiv ntawm qhov txhaum.

Cov fuses uas muaj feem ntau muaj cov iav raj iav, lub kaus mom hlau, thiab fuses. Ob lub kaus mom hlau tau muab tso rau ntawm ob qho kawg ntawm lub khob raj. Lub fuse (ua los ntawm cov khoom siv me me) tau muab ntsia rau hauv lub khob raj. Qhov kawg ob kawg yog welded rau lub qhov nruab nrab ntawm ob lub kaus mom hlau feem. Thaum siv, lub fuse yog thauj mus rau hauv lub rooj zaum nyab xeeb thiab tuaj yeem txuas nrog hauv cov koob nrog Circuit Court.
Feem ntau fuses ntawm fuses yog linear, tsuas yog xim TV, lub computer saib xyuas siv hauv kev ncua fuses rau kauv fuses.
Qhov tseem ceebPArameters ntawmCtxhais ua npaujFkev siv
Cov ntsiab lus tseem ceeb ntawm kev fuse ua haujlwm yog rated tam sim no, ntsuas voltage, ambient kub thiab cov kev ceev ceev. Qhov ntsuas (tseem hu ua kev tawg muaj peev xwm, hais txog tus nqi tam sim no uas lub fuse tuaj yeem tawg ntawm kev ntsuas hluav taws xob. Cov kev ua haujlwm ib txwm muaj tam sim no ntawm fuse yuav tsum tau 30% qis dua li cov ntaus nqi tam sim no. Qhov kev ntsuam xyuas tam sim no ntawm kev ua haujlwm hauv tsev feem ntau yog cim ncaj qha rau ntawm lub kaus mom hlau, thaum lub nplhaib xim ntawm cov khoom fuses ntawm cov cim ntawm lub khob raj.
Cov nqi hluav taws xob ntsuas yog hais txog feem ntau cov kev tswj hwm feem ntau ntawm cov fuse, uas yog 32V, 250V, 250V thiab 600v plaub qhov tshwj xeeb. Qhov tseeb ua haujlwm voltage ntawm lub fuse yuav tsum qis dua los yog sib npaug rau cov nqi hluav taws xob ntsuas. Yog tias cov kev ua haujlwm hluav taws xob ntawm lub fuse tau tshaj qhov ntsuas hluav taws xob, nws yuav tau tawg sai.
Txoj kev nqa khoom tam sim no ntawm cov fuse yog xeem ntawm 25 ℃. Cov kev pabcuam lub neej ntawm fuses yog inversely proportional rau cov huab cua sov. Qhov siab dua cov huab cua sov, qhov ntau dua qhov kev ua haujlwm kub ntawm lub fuse, tus luv luv nws lub neej.
Cov lus teb ceev yog hais txog qhov nrawm nrog uas fuse teb rau ntau yam hluav taws xob. Raws li cov tshuaj tiv thaiv ceev thiab kev ua tau zoo, fuses tuaj yeem faib ua hom lus teb ib txwm muaj, kev kawm luv thiab kev txiav txim siab tam sim no.
(2) thermal fuses
Thermal fuse, tseem paub txog qhov kub fuse, tseem muaj hom kev tsis raug cai, lub tshuab nqus tsev, kiv cua hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob. Thermal fuses tuaj yeem muab faib ua cov khoom siv thermal alloy hom thermal

Qhov kub hnov lub cev ntawm qis melting point alloy hom kub fuse yog machined los ntawm alloy melting point. Thaum qhov kub txog rau lub melting taw tes ntawm alloy, qhov kub hnov lub cev yuav tau fused, thiab muaj kev tiv thaiv Circuit Court yuav raug txiav tawm. Raws li nws cov qauv sib txawv, qis melting taw tes alloy hom qis qis melting point tuaj yeem faib ua cov hom kev sib koom ua ke, hom kev xav txog peb.

Kev rov qab kho tus kheej yog qhov ntsuas kub zoo coefficient PTCOSensitate, yog nyob rau hauv Circuit Court, thiab lwm yam.
Thaum lub Circuit Court tab tom ua haujlwm ib txwm ua, tus kheej - rov qab fuse yog nyob. Thaum muaj kev ua txhaum ntau dhau ntawm Circuit Court, qhov ntsuas kub ntawm Fuse nws tus kheej yuav nce nrawm, thiab tus thawj coj yuav dhau los ua insulator, txiav tawm qhov tam sim no hauv Circuit Court thiab ua Circuit Court nkag mus rau lub xeev tiv thaiv. Thaum qhov kev txhaum ploj thiab rov qab kho tus kheej fuse txias, nws yuav siv sijhawm ntawm lub xeev qis thiab txuas ntxiv txuas rau Circuit Court.
Kev khiav hauj lwm nrawm ntawm tus kheej txoj kev rov qab kho tus kheej yog cuam tshuam nrog qhov txawv txav tam sim no thiab huab cua sov. Qhov loj dua qhov tam sim no yog thiab qhov siab dua qhov kub yog, qhov nrawm dua ntawm kev ua haujlwm nrawm yuav yog.
