Dab tsi yog hom siv feem ntau fuses?
1. Lub tshuab hluav taws xob txuas muaj cov qauv yooj yim, tus nqi qis thiab kev hloov pauv yooj yim. Thaum siv, ntxig daim plooj npog rau hauv plooj (porcelain) thiab tshem daim plooj (porcelain cover) los hloov lub fuse. Plug-in fuses feem ntau siv nyob rau hauv qhov kawg ntawm cov xov hluav taws xob tsawg lossis ceg kab hluav taws xob nrog cov ntsuas hluav taws xob ntawm 380V thiab qis dua thiab ntsuas cov dej ntws ntawm 5 ~ 200A, raws li kev tiv thaiv luv luv ntawm cov kab thiab cov khoom siv hluav taws xob, thiab tseem ua kev tiv thaiv kev sib tshooj. hauv qhov hluav taws xob ncig.
2. Lub tshuab fuse ntawm qhov muab kauv fuse yog nruab nrog quartz xuab zeb, fuse thiab fuse qhov taw qhia nrog lub ntsej muag me me. Lub quartz xuab zeb yog siv los txhim kho arc extinguishing kev ua tau zoo. Tom qab fuse tshuab, muaj ib qho pov thawj pom tseeb. Thaum lub fuse raug cua tshuab, qhov ntsuas tau tshwm sim tam sim ntawd thiab tuaj yeem pom los ntawm lub khob qhov ntawm daim iav ntim. Nws yog feem ntau siv rau hauv kev siv hluav taws xob tswj ntawm cov cuab yeej siv tshuab. Nws muaj qhov tawg loj tam sim no thiab tuaj yeem siv rau kev tiv thaiv luv luv hauv kev tiv thaiv hauv Circuit Court nrog qhov ntsuas voltage ntawm 500V thiab qis dua thiab theem tam sim no ntawm 200A.
3. Cov fuses raug kaw tau muab faib ua ob hom: cov fuses uas muaj lawm thiab fuses tsis puv. Ua cov fuses feem ntau siv cov nplais square plooj zeb nrog quartz xuab zeb thiab yaj sab hauv, nrog muaj zog rhuav lub peev xwm. Lub raj fuse yog ua los ntawm cov ntawv hlau, thiab ob qhov kawg yog cov kaus mom uas tshem tau yog ua los ntawm tooj dag. Qhov yaj ntawm lub raj yog qhov sib txawv ntawm qhov chaw hla. Qhuav, nws yog qhov yooj yim dua los hloov cov yaj. Ntawm cov fuses uas siv tau yog siv hauv cov hluav taws xob nrog hluav taws xob qis dua 500V thiab cov theem tam sim no qis dua 1kA; non-muab tub ntim cov fuses muab cov melt rau hauv lub tog raj kheej kaw nrog lub pob tawg me me muaj peev xwm. Nws siv rau kev siv fais fab lossis cov xa tawm hauv qab 500V thiab qis dua 600A. Cov khoom siv hluav taws xob.
4. Lub thawv hluav taws xob sai yog siv rau qhov luv tiv thaiv ntawm kev tiv thaiv ntawm cov khoom sib txuas ntawm cov khoom sib txuas lossis cov twj txuas hluav taws xob. 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. Nws cov qauv yog ib txwm zoo ib yam li ntawm cov fuse uas muaj qhov muab tub lim, tab sis cov khoom yaj 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 ua haujlwm tus kheej fuse siv sodium hlau li lub melt, uas muaj qhov siab ua haujlwm ntawm chav tsev kub. Thaum luv luv Circuit Court tshwm sim nyob rau hauv Circuit Court, luv luv-Circuit Court tam sim no ua rau muaj lub siab kub kom ceev ceev cov dej sodium, thiab cov vaporized sodium nthuav tawm lub xeev muaj qhov siab tiv thaiv, thiaj li txwv tsis pub luv 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 zoo conductivity. 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.
