Nws nyob hauv nws lub peev xwm los tiv thaiv qhov tam sim no mem tes tam sim no, uas yog hais tias, nws tuaj yeem tiv thaiv qhov cuam tshuam ntawm qhov hluav taws xob tam sim no thaum hloov mus rau thiab tawm yam tsis muaj kev ua yeeb yam, txhawm rau ua kom lub cev ua haujlwm ntawm cov khoom siv. Yog li ntawd, lub tshuab qeeb qeeb feem ntau hu ua surge-resistant fuse. Los ntawm cov kev taw qhia ntawm kev pom, lub tshuab qeeb qeeb muaj qhov loj dua melting kub nqi I2t, thiab lub zog xav tau rau lub fuse tshuab yog loj dua. Yog li ntawd, rau lub fuse nrog tib lub ntsuas tam sim no, lub tshuab qeeb qeeb muaj zog ntau dua li qhov nrawm nrawm nrawm.
Txij li thaum I2t ntawm lub tshuab qeeb qeeb yog loj dua li ntawm lub tshuab nrawm nrawm ntawm tib qhov kev qhia tshwj xeeb, lub sijhawm fuses yuav qeeb dua li ntawm lub tshuab hluav taws xob nrawm thaum muaj overcurrent tshwm sim hauv Circuit Court. Puas yuav tiv thaiv kev ua haujlwm tsis zoo li qee cov neeg txhawj xeeb? ? Peb hais tsis yog! Vim hais tias ib zaug lub Circuit Court tawg, lub overcurrent yuav tsis ploj los ntawm nws tus kheej, thiab lub zog ntawm lub nruam overcurrent yuav zoo heev tshaj I2t ntawm lub fuse. Tsis muaj teeb meem dab tsi ntawm fuse yuav raug tshuab, lub sij hawm sib txawv ntawm lub tshuab qeeb thiab ceev tshuab yog qhov tseem ceeb rau nws cov kev tiv thaiv. Nws tsis tseem ceeb heev. Tsuas yog thaum muaj cov khoom siv rhiab hauv kev tiv thaiv hluav taws xob uas xav tau kev tiv thaiv, lub tshuab qeeb qeeb yuav muaj kev cuam tshuam rau kev tiv thaiv kev ua haujlwm.
Vim yog qhov sib txawv saum toj no, cov fuses qeeb thiab lub tshuab nrawm yog siv nyob rau hauv ntau lub circuits: fast-blow fuses yuav tsum tau siv nyob rau hauv purely resistive circuits (tsis muaj los yog ob peb surges) los yog circuits uas yuav tsum tau tiv thaiv rhiab thiab muaj nuj nqis Cheebtsam xws li ICs; Rau cov capacitive lossis inductive circuits (muaj qhov tshwm sim thaum hloov mus rau thiab tawm), nws yog qhov zoo tshaj plaws los siv lub tshuab qeeb qeeb rau cov khoom siv hluav taws xob / tawm ntawm lub zog; Ntxiv nrog rau kev tiv thaiv Circuit Court ntawm IC, feem ntau ntawm lub sijhawm uas siv lub tshuab hluav taws xob nrawm tuaj yeem hloov nrog lub tshuab qeeb qeeb. Txhawm rau txhim kho lub peev xwm tiv thaiv kev cuam tshuam; ntawm qhov tsis sib xws, yog tias lub fuse ua haujlwm nrawm siv los hloov lub fuse ua haujlwm qeeb, nws yuav ua rau muaj qhov tshwm sim uas lub fuse tam sim no tsis tuaj yeem ua haujlwm ib txwm.
