Dab tsi ntawm fuse yog muaj?
Ntau hom thiab kev siv ntawm cov fuses uas ib txwm muaj
(1) Plug-nyob rau hauv fuse
Nws feem ntau siv rau ntawm qhov kawg ntawm kab nrog voltage theem ntawm 380V thiab hauv qab raws li luv luv-thaiv kev tiv thaiv rau kev faib ceg kab lossis khoom siv hluav taws xob.
(2) Ntsia thawv fuse
Muaj qhov taw qhia fuse nyob ntawm qaum kawg npog ntawm lub yaj. Thaum cov yaj yaj tag lawm, qhov ntsuas tau tshwm sim tam sim ntawd thiab tuaj yeem pom los ntawm daim iav qhov ntawm lub hau ceramic. Nws feem ntau siv hauv kev tswj hwm hluav taws xob rau cov khoom siv tshuab. Nws yog hu ua cov ntsia hlau fuse.
Qhov tawg tam sim no loj heev, thiab nws tuaj yeem siv rau kev tiv thaiv luv luv hauv kev tiv thaiv kab hluav taws xob nrog qhov voltage ntawm 500V thiab qis dua thiab theem tam sim no ntawm 200A.
(3) Lub kaw fuse
Cov fuses uas tau muab kaw tau muab faib ua ob hom: cov fuses uas muaj lawm thiab cov fuses uas tsis tau puv
Ua fuses feem ntau siv cov plaub hau plooj (veneers) cov hlab nrog quartz xuab zeb thiab yaj sab hauv. Lawv muaj lub zog tawg qhov muaj peev xwm thiab siv tau hauv cov hluav taws xob nrog voltage theem qis dua 500V thiab cov theem tam sim no qis dua 1KA.
Lub kaw lus fuse tsis muaj zog txo nws lub melt mus rau hauv lub tog raj kheej kaw nrog lub pob tawg me me thiab muaj peev xwm siv rau hauv cov xaim hluav taws xob lossis cov khoom siv fais fab faib qis dua 500V thiab qis dua 600A.

Filled kaw raj fuse
1- Porcelain puag 2- nplooj hlav nplooj 3- Lub cev lub cev 4- Insulated kov 5- Yaj
(4) fuse sai
Nws yog tsuas yog siv rau kev tiv thaiv luv luv ntawm semiconductor rectifier Cheebtsam lossis cov khoom siv txuas ntxiv. Vim tias muaj ntau dhau los muaj peev xwm ntawm cov khoom sib txuam.
Nws muaj peev xwm tiv taus qhov loj ntawm cov khoom sib tshooj loj hauv lub sijhawm luv luv, yog li kev tiv thaiv luv luv ntawm kev tiv thaiv yog qhov yuav tsum muaj peev xwm ua kom sai.
Cov qauv ntawm cov fuse ceev yog qhov tseeb tib yam li ntawm qhov puv kaw fuse, tab sis cov khoom sib xyaw thiab cov duab sib txawv. Nws yog cov kuj sib txawv thiab tus ntoo khaub lig-seem yaj nrog V-puab sib sib zog nqus zawj punched los ntawm daim ntawv nyiaj.
(5) Kev rov kho tus kheej rov fuse
Kev siv cov xim hlau tom qab ua cov yaj, nws muaj cov cwj pwm siab ntawm chav tsev kub. Thaum luv luv Circuit Court tshwm sim nyob rau hauv Circuit Court, lub luv-Circuit Court tam sim no ua rau muaj qhov kub kub kom sai sai rau vaporize sodium, thiab vaporized sodium nthuav tawm lub xeev muaj qhov siab tiv thaiv, thiaj li txwv tsis pub luv-tam sim no.
Thaum lub luv-Circuit Court tam sim no ploj, qhov kub poob thiab cov hlau sodium rov qab nws cov thawj coj zoo. Kev rov teeb tsa tus kheej fuse tuaj yeem txwv luv luv-Circuit Court tam sim no thiab tsis tuaj yeem txhaum lub Circuit Court.
Qhov zoo dua yog tias cov yaj tsis tas yuav tsum tau hloov chaw thiab tuaj yeem rov siv dua.
Thaum ua haujlwm, lub fuse txuas nrog hauv cov hluav taws xob tiv thaiv. Thaum lub Circuit Court luv luv-circuited lossis hnyav ntau dhau, lub fuse hauv fuse yuav cia li tshuab thiab ua lub luag haujlwm tiv thaiv. Qhov feem ntau yog tus fuse.
