Lub hauv paus ntsiab lus ntawm fuse

Lub hauv paus tseem ceeb ntawm lub fuse yog nws cov hlau sab hauv los yog alloy. Thaum tam sim no ntws los ntawm nws, cov hlau heats li vim lub thermal nyhuv ntawm tam sim no. Yog tias qhov tam sim no tshaj qhov fuse tus nqi ntsuas, cov hlau melts thiab tawg lub voj voog. Qhov no yog ib qho - siv cov cuab yeej tiv thaiv; Thaum nws tshuab, lub fuse yuav tsum tau hloov.

Hauv kev tsim cov fuses, cov hlau sab hauv yog feem ntau yog ua los ntawm cov hlau ntshiab lossis hlau, nrog rau cov khoom xaiv uas muaj cov ntsiab lus melting tsawg thiab muaj qee yam tsis kam. Lub resistivity thiab melting point ntawm lub fuse lub internal hlau hlau yog precisely xaiv raws li nws cov kev khiav hauj lwm ib puag ncig. Piv txwv li, cov khoom siv xws li txhuas, tin, thiab nyiaj tuaj yeem ua kom sov sai sai rau lawv qhov melting point thiab yaj thaum tam sim no overloaded.
