DC fuse yog ib qho khoom siv uas tsim los tiv thaiv hluav taws xob hluav taws xob los ntawm kev puas tsuaj los ntawm cov khoom siv hluav taws xob ntau dhau, feem ntau tshwm sim los ntawm overload lossis luv luv Circuit Court.Nws yog ib hom khoom siv hluav taws xob kev nyab xeeb uas siv hauv DC (direct tam sim no) hluav taws xob tshuab los tiv thaiv overcurrent thiab luv circuits.
DC fuses zoo ib yam li AC fuses, tab sis lawv tau tsim tshwj xeeb rau kev siv hauv DC circuits.Lawv feem ntau yog ua los ntawm cov hlau conductive lossis alloy uas yog tsim los rau yaj thiab cuam tshuam rau hauv Circuit Court thaum tam sim no tshaj ib theem.Lub fuse muaj ib txoj hlua nyias los yog hlau uas ua raws li cov khoom siv hluav taws xob, uas tau tuav hauv qhov chaw los ntawm cov qauv kev txhawb nqa thiab muab ntim rau hauv lub thawv tiv thaiv.Thaum cov tam sim no ntws los ntawm lub fuse tshaj qhov ntsuas tus nqi, cov khoom siv hluav taws xob yuav sov thiab thaum kawg yaj, tawg lub voj voog thiab cuam tshuam qhov ntws ntawm tam sim no.
DC fuses yog siv nyob rau hauv ntau yam kev siv, xws li tsheb thiab aviation hluav taws xob systems, solar panels, roj teeb systems, thiab lwm yam DC hluav taws xob systems.Lawv yog ib qho tseem ceeb ntawm kev nyab xeeb uas pab tiv thaiv hluav taws xob hluav taws xob thiab lwm yam kev phom sij.
