Fuse yog dab tsi?
Kev Txhais Hauv Electronics / Hluav Taws Xob
Cov cuab yeej tseem ceeb rau kev tiv thaiv los ntawm overcurrent tej yam
Hlau sawb dissolves nrog ntau tam sim no, qhib Circuit Court
Kuj tsis siv neeg raws li tsis siv neeg disconnection ntawm cov khoom (ADS)
Pheej yig thiab cov siv tau siv rau cov kev tiv thaiv luv luv lossis kev tiv thaiv zoo tam sim no
Vim li cas peb thiaj li xav tau fuse?
Lub hom phiaj:
Tiv thaiv cov khoom siv hauv tsev los ntawm qhov siab tam sim no lossis overload kev puas tsuaj
Tiv thaiv kev thaiv kev yuam kev thiab cov phom phom
Abrupt spark thaum fuse soam tuaj yeem ua rau cov khoom siv kev puas tsuaj
Xav tau ntau yam sib txawv ntawm cov fuses rau kev tiv thaiv zoo
Fuses rated hauv amperes; raws li cov cua sov tsim los ntawm kev tiv thaiv
Cov Hlau Ntsej Muag Ntev, tsawg kawg
Minimal hlau ntev, tsawg kawg tsis kam
Cov yam ntxwv ntawm Fuses
Tus nqi ntsuas tus nqi tam sim no
Qhov siab tshaj plaws tam sim no tsis melting
Ntsuas hauv amperes; muaj cov yam ntxwv thermal
Voltage ntsuas nqi
Kev sib txuas; Voltage ntsuas tsis tau augmented
Qho so
Kev ua haujlwm siab dua kub txo tus nqi tam sim no, ua rau melting
Tso tseg
Ntxiv tam sim no nce ntxiv kub, ua rau melting; Volfage poob yog tsawg heev tom qab melting
Ua haujlwm ua haujlwm ntawm Fuse
Cua sov cov nyhuv ntawm tam sim no
Constructed nrog nyias xim hlau strip / xov
Ib txwm txuas nrog hauv koob
Siab Tam Sim No Cov Khoom Siv Hluav Taws Xob, qhib Circuit Court, txwv tsis pub muaj
Kev Ua Haujlwm Li Qub: Thaum tshav kub dissipated, kub me me melting point
Txhaum Cai: Muaj Kub Tam Sim No, Kev Kub Siab, Fuse thiab so, tiv thaiv los ntawm overload / Luv Circuit Court
FOLT
Ua los ntawm kev xaiv cov hlau pib
Tso cai rau tsuas yog txwv tam sim no; tawg Circuit Court yog tshaj
Muab OvervolTage Kev Txawj Ntse
Cov ntsiab lus tsim:
Hloov tau nrog tib lub zog ntsuas ntsuas pob qij
Cov Khoom Siv: Tooj (Cu), Zinc (Zinc (Zn), Al), Nyiaj (AG)
Muaj nuj nqi raws li cov breaker thiab cov khoom siv kev nyab xeeb
Fuse cov lus ntsuas:
Fuse=(fais fab (watts) / voltage (volt)) x 1.25
Cov kauj ruam fuse:
Xaiv cov fuse
Sau cov khoom siv siv khoom siv (v) thiab lub zog (w)
Xam ntsuas nyiaj fuse fuse
Siv ntxiv siab tshaj plaws muaj kev ntsuas fuse (E {. g., 7.689a → siv 8a fuse)
OverVolTage Supression hauv FIMES
Ntxiv nrog rau kev txwv tam sim no, Fused kuj tseem ua lub luag haujlwm ntawm kev tiv thaiv cov khoom siv ntawm qhov no, uas tuaj yeem siv nrog kev tiv thaiv kev nyab xeeb rau ob qho tib si tam sim no thiab qhov hluav taws xob Spikes .
Cov khoom siv zoo li cov cua sov tsis zoo (NTC) cov cua nab cij feem ntau yog muab tso rau hauv parallel {}} Cov khoom siv hluav taws xob ntau dhau, cov khoom siv hlau ua kom muaj peev xwm nqus tau cov khoom siv hluav taws xob ntau dhau, muab kev tiv thaiv ntxiv los ntawm kev hloov pauv hloov pauv .
Los ntawm kev sib xyaw ua ke cov ntsiab lus no, lub fuse tsis muaj kev tiv thaiv kev nyab xeeb thiab luv luv ntawm kev nyab xeeb ntawm cov hluav taws xob ntawm cov hluav taws xob uas muaj teeb meem hluav taws xob .
Qhov kev tsim kho yooj yim ntawm lub fuse yog qhia raws li hauv qab no:
Ib lub fuse hauv hluav taws xob hluav taws xob tuaj yeem hloov pauv los ntawm kev tso cov hluav taws xob tshiab uas muaj cov hluav taws zoo sib xws xws li CU (tooj liab), Zn (zinc),
Al (Aluminium), thiab AG (Nyiaj) . Lawv tseem ua tau zoo li lub Circuit Court breaker tshwm sim hauv Circuit Court {}} Qhov no ua haujlwm zoo li kev nyab xeeb
ntsuas lossis tiv thaiv rau tib neeg los ntawm kev pheej hmoo . zoo li no, lub fuse ua haujlwm .
Fuse=(fais fab (watts) / voltage (volt)) x 1.25
Kev xaiv ntawm fuse tuaj yeem ua tau los ntawm kev suav cov ntsuas fuse los ntawm kev siv cov mis saum toj no .
Xaiv lub fuse .
Sau cia lub voltage (volts) thiab fais fab (watts) ntawm cov khoom siv .
Xam cov fuse qhov ntsuas .
Tom qab qhov tshwm sim, siv cov nyiaj fuse siab tshaj plaws .}}}} nws txhais tau tias thaum xam qhov ntsuas fuse
Puas yog 7 {. 689 amps, ces ib lub fuse nrog 8 amps yuav tsum haum hauv hluav taws xob hluav taws xob.
