Fast- ua fuse yog ib hom fuse, uas yog siv los tiv thaiv luv luv Circuit Court ntawm cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob rectifier. Cov qauv ntawm cov fuse ceev yog qhov pib zoo ib yam li cov fuse kaw nrog cov muab tub lim, tab sis cov khoom yaj thiab cov duab sib txawv. Nws yog qhov sib txawv ntawm tus ntoo khaub lig- ntu yaj nrog V- zoo li qhov sib sib zog nqus groove punched los ntawm ib daim ntawv nyiaj. Ntxiv nrog rau cov hlau hlau uas muaj qee yam zoo li, lub fuse ntawm lub fuse ceev kuj tseem raug cim nrog ib qho kev sib koom ua ke ntawm qee yam khoom ntawm nws, yog li kom tshem tawm lub fuse sai dua.
Fast- ua yeeb yam fuse feem ntau yog siv rau kev tiv thaiv luv luv ntawm cov khoom siv hluav taws xob rectifier lossis cov khoom siv rectifier. Raws li lub peev xwm dhau ntawm cov khoom siv semiconductor tsawg heev, lawv tsuas tuaj yeem tiv taus cov khoom loj dhau tam sim no hauv lub sijhawm luv luv, yog li luv luv - tiv thaiv Circuit Court yuav tsum muaj peev xwm fuse sai. Fast fuse highlights "ceev", uas txhais tau hais tias siab rhiab heev. Thaum lub Circuit Court tam sim no overloaded, lub fuse yuav kub sai sai nyob rau hauv qhov kev txiav txim ntawm lub solder sib koom, thiab sai sai disconnect lub fuse. Lub fuse zoo ceev muaj kev ua haujlwm siab, uas yog siv los tiv thaiv silicon tswj rectifier thiab qee cov khoom siv hluav taws xob hluav taws xob.
