Lub luag haujlwm tseem ceeb ntawm lub fuse yog los tiv thaiv hluav taws xob hluav taws xob los ntawm kev puas tsuaj vim tam sim no ntau dhau. Nov yog yuav ua li cas lub fuse ua tiav qhov no:
Kev tiv thaiv overcurrent:Lub fuse yog tsim los cuam tshuam qhov ntws ntawm tam sim no hauv ib lub voj voog yog tias qhov tam sim no tshaj li ib qib (rated tam sim no). Qhov no tshwm sim thaum muaj qhov txhaum, xws li luv luv lossis overload.
Fusing Element:Cov ntsiab lus tseem ceeb ntawm lub fuse yog ib daim nyias nyias los yog cov hlau ua los ntawm cov khoom uas tsis tshua muaj melting point, xws li tooj liab, nyiaj, los yog hlau alloy. Lub strip no hu ua lub fuse.
Kev ntsuas tam sim no:Txhua lub fuse raug ntsuas rau tus nqi tam sim no, feem ntau ntsuas hauv amperes (A). Thaum cov tam sim no ntws los ntawm Circuit Court tshaj qhov ntsuas tus nqi rau lub sij hawm tseem ceeb, lub fuses heats li vim hluav taws xob tsis kam.
Kev ua haujlwm fuse:Raws li qhov tam sim no tshaj qhov ntsuas tus nqi, cov khoom sib xyaw ua kom sov thiab nws thiaj li melts (los yog tshuab) vim cov cua kub ntau dhau. Qhov no melting ntawm lub fuse caij lov cov hluav taws xob Circuit Court thiab nres cov ndlwg ntawm tam sim no.
Lub luag haujlwm tiv thaiv:Los ntawm kev rhuav tshem lub voj voog, lub fuse tiv thaiv kev ntws ntawm tam sim no los ntawm qhov txhaum, yog li tiv thaiv cov cuab yeej rhiab thiab cov khoom siv los ntawm kev puas tsuaj lossis hluav taws kub nyhiab uas tuaj yeem tshwm sim los ntawm overheating lossis overcurrent tej yam kev mob.
Rov pib dua:Fuses feem ntau yog siv ib zaug xwb; thaum lawv tshuab (melt), lawv yuav tsum tau hloov. Qhov no ua kom ntseeg tau tias lub Circuit Court tseem tiv thaiv kev ua txhaum tom ntej.
Daim ntawv thov:Fuses yog siv nyob rau hauv ntau yam khoom siv hluav taws xob thiab hluav taws xob, los ntawm cov khoom siv hauv tsev thiab cov khoom siv teeb pom kev zoo rau cov khoom siv thiab cov tshuab tsheb. Lawv yog cov khoom tseem ceeb hauv kev ua kom muaj kev nyab xeeb hluav taws xob thiab tiv thaiv kev puas tsuaj rau cov khoom siv muaj txiaj ntsig.
