Lub charger pawg fuse yog raws li qhov tseeb hais tias tom qab qhov tam sim no tshaj qhov teev nqi rau ib lub sij hawm ntawm lub sij hawm, lub tshav kub generated los ntawm nws tus kheej melts melts, yog li disconnecting lub Circuit Court; tus tiv thaiv tam sim no tau siv txoj cai no. Fuses tau dav siv hauv cov tshuab hluav taws xob qis hluav taws xob, tswj cov tshuab thiab cov khoom siv hluav taws xob. Raws li lub voj voog luv luv thiab dhau tam sim no them pawg tiv thaiv, nws yog ib qho ntawm cov khoom siv tiv thaiv feem ntau.
Lub charger pawg fuse yog ib qho kev tiv thaiv overcurrent. Lub charger pawg fuse yog tsim los ntawm yaj, melting tube thiab lwm tus muab tub lim. Thaum siv, txuas lub charger pawg fuse hauv series nrog cov tiv thaiv Circuit Court. Thaum qhov tam sim no ntawm cov kev tiv thaiv Circuit Court tshaj li tus nqi teev thiab tom qab ib lub sij hawm ntawm lub sij hawm, lub tshav kub generated los ntawm yaj nws tus kheej fuses lub yaj thiab disconnects lub Circuit Court. Tiv thaiv lub luag haujlwm ntawm kev them cov pawg.
Ib qho khoom siv hluav taws xob uas siv cov khoom siv hlau ua cov yaj los ua kom tawg rau hauv Circuit Court yog txuas nrog rau hauv series hauv Circuit Court. Thaum lub overload los yog luv-circuit tam sim no dhau los ntawm cov yaj, cov yaj nws tus kheej yuav sov thiab fuse, yog li ua lub luag haujlwm hauv lub zog hluav taws xob, ntau yam khoom siv hluav taws xob thiab khoom siv hauv tsev. kev tiv thaiv. Nws muaj cov yam ntxwv ntawm kev ncua sijhawm ncua sijhawm. Thaum lub overload tam sim no me me, lub sij hawm fusing yog ntev; thaum lub overload tam sim no loj, lub sij hawm fusing yog luv. Yog li ntawd, nyob rau hauv ib tug tej yam overload tam sim no ntau yam kom txog rau thaum tam sim no rov qab mus rau qhov qub, lub fuse yuav tsis raug tshuab thiab siv tau mus ntxiv. Lub fuse feem ntau yog tsim los ntawm peb ntu: yaj, lub plhaub thiab kev txhawb nqa. Lub yaj yog lub hauv paus tseem ceeb los tswj cov yam ntxwv fuse.
