Fuses tiv thaiv cov khoom siv hluav taws xob los ntawm cov hluav taws xob tam sim no thiab tiv thaiv kev puas tsuaj loj los ntawm kev ua tsis tiav sab hauv.Yog li ntawd, txhua lub fuse muaj qhov ntsuas, thiab lub fuse yuav tshuab thaum tam sim no tshaj qhov ntsuas.Thaum ib tug tam sim no siv rau ib tug fuse uas nyob nruab nrab ntawm cov pa unfused tam sim no thiab cov rated tawg muaj peev xwm teev nyob rau hauv tus txheej txheem, lub fuse yuav tsum ua hauj lwm txaus siab thiab tsis muaj kev puas tsuaj rau ib puag ncig ib puag ncig.
Qhov kev cia siab tam sim no ntawm lub voj voog uas lub fuse raug teeb tsa yuav tsum tsawg dua li qhov ntsuas qhov muaj peev xwm tam sim no tau teev tseg hauv tus qauv.Txwv tsis pub, thaum muaj qhov txhaum tshwm sim, lub fuse yuav txuas ntxiv ya mus, ignite, hlawv lub fuse, yaj ua ke nrog kev sib cuag, thiab lub cim fuse tsis tuaj yeem lees paub.Tau kawg, lub peev xwm tawg ntawm lub fuse tsis zoo tuaj yeem ua tsis tau raws li qhov yuav tsum tau teev tseg hauv tus qauv, thiab kev siv tib yam kev puas tsuaj yuav tshwm sim.
Ntxiv nrog rau fusing resistors, kuj tseem muaj cov fuses dav dav, thermal fuses thiab nws tus kheej fuses.Cov khoom tiv thaiv feem ntau txuas nrog hauv series hauv Circuit Court, nws nyob rau hauv Circuit Court ntawm dhau tam sim no, dhau voltage lossis overheating thiab lwm yam txawv txav tshwm sim, yuav tam sim ntawd fuse thiab ua lub luag haujlwm tiv thaiv, tuaj yeem tiv thaiv kev nthuav dav ntxiv ntawm qhov txhaum.
(1) OrdinaryFsiv
Cov fuses qub, feem ntau hu ua fuses lossis fuses, yog cov fuses uas tsis tuaj yeem rov qab tau, thiab tsuas yog hloov tau nrog cov fuses tshiab tom qab fuses.Nws tau qhia los ntawm "F" lossis "FU" hauv Circuit Court.
Kev tsim qauvCharacteristics ntawmCommon uaFsiv
Cov fuses feem ntau muaj cov iav raj, lub kaus mom hlau, thiab fuses.Ob lub kaus mom hlau yog muab tso rau ntawm ob qho kawg ntawm lub iav raj.Lub fuse (ua los ntawm cov khoom siv hlau melting tsawg) yog ntsia rau hauv lub khob raj.Ob qhov kawg yog welded rau qhov chaw nruab nrab ntawm ob lub kaus mom hlau feem.Thaum siv, lub fuse yog loaded rau hauv lub rooj zaum muaj kev ruaj ntseg thiab tuaj yeem txuas rau hauv series nrog lub voj voog.
Feem ntau cov fuses ntawm fuses yog linear, tsuas yog xim TV, lub computer saib siv nyob rau hauv ncua fuses rau kauv fuses.
MainParameters ntawmCommon uaFsiv
Lub ntsiab tsis zoo ntawm cov fuse zoo tib yam yog ntsuas tam sim no, ntsuas qhov ntsuas hluav taws xob, qhov ntsuas kub thiab cov tshuaj tiv thaiv ceev.Rated tam sim no, tseem hu ua tawg peev xwm, hais txog tus nqi tam sim no uas lub fuse tuaj yeem tawg ntawm qhov ntsuas hluav taws xob.Qhov kev khiav hauj lwm tam sim no ntawm lub fuse yuav tsum yog 30% qis dua qhov ntsuas tam sim no.Qhov ntsuas tam sim no ntawm cov fuses hauv tsev feem ntau yog cim ncaj qha rau ntawm lub hau hlau, thaum lub nplhaib xim ntawm cov fuses txawv teb chaws raug cim rau ntawm lub iav raj.
Rated voltage yog hais txog qhov feem ntau tswj voltage ntawm lub fuse, uas yog 32V, 125V, 250V thiab 600V plaub specifications.Qhov tseeb ua hauj lwm voltage ntawm lub fuse yuav tsum qis dua los yog sib npaug rau qhov ntsuas voltage tus nqi.Yog hais tias qhov kev khiav hauj lwm voltage ntawm lub fuse tshaj qhov ntsuas voltage, nws yuav raug cua tshuab sai sai.
Lub peev xwm nqa tam sim no ntawm lub fuse raug kuaj ntawm 25 ℃.Lub neej kev pab cuam ntawm fuses yog inversely proportional rau ambient kub.Qhov siab dua qhov kub ntawm qhov chaw, qhov siab dua qhov kev ua haujlwm ntawm lub fuse, lub neej luv dua.
Teb ceev yog hais txog qhov ceev uas lub fuse teb rau ntau yam hluav taws xob loads.Raws li cov tshuaj tiv thaiv ceev thiab kev ua tau zoo, fuses tuaj yeem muab faib ua hom lus teb ib txwm, ncua sijhawm so, hom kev ua haujlwm ceev thiab tam sim no txwv hom.
(2) Thermal Fuses
Thermal fuse, tseem hu ua kub fuse, yog ib yam ntawm unrecoverable overheating pov hwm lub caij, lug siv nyob rau hauv txhua yam ntawm hluav taws xob cookware, lub cev muaj zog, ntxhua khaub ncaws, hluav taws xob kiv cua, transformer fais fab thiab lwm yam khoom siv hluav taws xob.Thermal fuses tuaj yeem muab faib ua qis melting point alloy hom thermal fuses, organic compound type thermal fuses thiab yas-hlau hom thermal fuses raws li qhov sib txawv ntawm qhov ntsuas kub ntawm lub cev.
TsawgMeltingPtshuaj pleevAlojType uaTtshuaj ntsuabFsiv
Qhov ntsuas kub ntawm lub cev ntawm qhov tsis tshua muaj melting point alloy hom kub fuse yog machined los ntawm cov khoom siv alloy nrog tsau melting point.Thaum qhov kub nce mus txog qhov melting point ntawm cov hlau, qhov ntsuas kub ntawm lub cev yuav raug txiav tawm, thiab kev tiv thaiv Circuit Court yuav raug txiav.Raws li nws cov qauv sib txawv, qis melting point alloy hom kub tsis tshua muaj melting point alloy hom kub fuse tuaj yeem muab faib ua hom gravity, nto nro hom thiab lub caij nplooj ntoos hlav tshuaj tiv thaiv hom peb.
OrganicCompoundType uaTtshuaj ntsuabFsiv
Organic compound thermal fuse yog tsim los ntawm qhov ntsuas kub ntawm lub cev, txav tau electrode, caij nplooj ntoos hlav thiab lwm yam.Kev ntsuas kub ntawm lub cev yog ua tiav los ntawm cov organic tebchaw nrog siab purity thiab qis fusing kub ntau.Feem ntau, cov khoom siv hluav taws xob txav tau thiab qhov kawg ntawm qhov chaw sib cuag, lub voj voog txuas nrog lub fuse;Thaum qhov kub thiab txias mus txog qhov melting point, qhov ntsuas kub ntawm lub cev txiav txim siab fuses, thiab cov hluav taws xob txav tau raug txiav tawm ntawm qhov kawg taw tes nyob rau hauv qhov kev txiav txim ntawm lub caij nplooj ntoos hlav, thiab lub Circuit Court raug txiav tawm rau kev tiv thaiv.
Yas -MetalTtshuaj ntsuabFsiv
Yas-hlau thermal fuses txais cov qauv nro saum npoo, thiab tus nqi ntawm qhov ntsuas kub ntawm lub cev yog yuav luag 0. Thaum qhov kub thiab txias ua haujlwm nce mus txog qhov ntsuas kub, qhov ntsuas qhov ntsuas kub ntawm lub cev yuav dheev nce, tiv thaiv qhov tam sim no dhau los.
(3) Self-Restoring Fuse
Self-restoring fuse yog ib yam tshiab ntawm kev nyab xeeb lub caij nrog overcurrent thiab overheat tiv thaiv muaj nuj nqi, uas yuav siv tau ntau zaus.
Kev tsim qauvPrinciple ntawmSelf -Rkhaws ciaFsiv
Self-restoring fuse yog ib tug zoo kub coefficient PTC thermosensitive caij, ua los ntawm polymer thiab conductive cov ntaub ntawv, thiab lwm yam, nws yog nyob rau hauv series nyob rau hauv lub Circuit Court, yuav hloov cov tsoos fuse.
Thaum lub Circuit Court ua hauj lwm ib txwm, tus kheej-restore fuse yog nyob rau.Thaum muaj overcurrent txhaum nyob rau hauv lub Circuit Court, qhov kub ntawm lub fuse nws tus kheej yuav nce sai heev, thiab cov khoom polymeric yuav sai sai nkag mus rau lub siab tiv thaiv lub xeev tom qab rhuab, thiab tus neeg xyuas pib yuav ua ib tug insulator, txiav tawm tam sim no nyob rau hauv lub Circuit Court. thiab ua rau lub voj voog nkag mus rau hauv lub xeev tiv thaiv.Thaum qhov kev ua txhaum ploj mus thiab tus kheej rov kho lub fuse txias, nws yuav siv sij hawm nyob rau hauv lub xeev uas tsis muaj zog conduction thiab cia li txuas lub Circuit Court.
Kev khiav hauj lwm ceev ntawm tus kheej fuse rov qab muaj feem xyuam rau qhov txawv txav tam sim no thiab qhov kub thiab txias.Qhov loj dua qhov tam sim no thiab qhov kub thiab txias dua, qhov kev khiav hauj lwm ceev yuav nrawm dua.
Feem ntauSelf -Rkhaws ciaFsiv
Self-resoring fuses muaj plug-in hom, nto mounted hom, nti hom thiab lwm yam qauv duab.Feem ntau siv plug-in fuses yog RGE series, RXE series, RUE series, RUSR series, thiab lwm yam., uas yog siv rau hauv computers thiab cov khoom siv hluav taws xob.
