Dab tsi yog cov khoom siv sab hauv ntawm high voltage fuses?

Nyob rau hauv lub hwj chim system, high-voltage fuses yog ib qho tseem ceeb ntawm kev tiv thaiv Circuit Court. Lawv tuaj yeem txiav tawm hluav taws xob sai sai thaum muaj overload lossis luv luv los tiv thaiv cov cuab yeej los ntawm kev puas tsuaj. Kev ua tau zoo ntawm high-voltage fuses nyob ntawm qhov tsis tsuas yog nyob ntawm lawv tus qauv, tab sis kuj nyob ntawm lawv cov khoom siv sab hauv. Yog li dab tsi yog cov ntsiab lus thiab cov ntaub ntawv ntawm high-voltage fuses?
Internal khoom ntawm high-voltage fuses:
1. Cov khoom siv yaj: Cov yaj yog cov tseem ceeb ntawm lub fuse. Feem ntau siv yaj cov ntaub ntawv muaj xws li tooj liab, nyiaj, txhuas-antimony alloy, thiab lwm yam. tooj liab thiab nyiaj yog haum rau cov ntaub ntawv siab tam sim no vim lawv cov conductivity siab thiab nruab nrab melting point. Lead-antimony alloy yog tsim rau me me thiab nruab nrab-muaj peev xwm fuses vim nws ruaj khov thiab qis melting point.
2. Cov khoom siv sib cuag: Cov kev sib cuag yog ib feem tseem ceeb ntawm kev sib txuas hauv Circuit Court thiab feem ntau yog ua los ntawm cov ntaub ntawv xws li tooj liab, nyiaj lossis txhuas. tooj liab yog dav siv rau nws zoo conductivity thiab mechanical zog, thaum nyiaj yog siv nyob rau hauv high-end fuses rau nws zoo heev conductive zog.
3. Ceramic lub cev: Lub plhaub sab nraud ntawm lub fuse feem ntau yog ua los ntawm cov ceramic, uas muab cov rwb thaiv tsev zoo thiab lub zog txhua yam los tiv thaiv cov khoom sab hauv los ntawm kev cuam tshuam sab nraud.
4. Cov khoom siv muab tub lim: cov ntaub ntawv sau xws li quartz xuab zeb txhim kho lub peev xwm tawg hauv lub fuse thiab pab tua cov arc.
5. Cov raj tiv thaiv: Cov raj tiv thaiv feem ntau yog ua los ntawm cov ntaub ntawv insulating, xws li cov porcelain raj lossis plexiglass, los muab cov rwb thaiv tsev ntxiv thiab kev tiv thaiv txhua yam rau lub fuse.
Cov kev xaiv sib txawv ntawm cov ntaub ntawv no muaj qhov sib txawv ntawm kev ua haujlwm, raws li tau piav qhia hauv qab no:
● Kev ua tau zoo: Kev ua tau zoo ntawm cov fuse feem ntau yog nyob ntawm cov khoom yaj thiab cov ntaub ntawv sib cuag. Cov ntaub ntawv uas muaj cov conductivity siab tuaj yeem txo lub zog poob thiab ua kom cov lus teb ceev ntawm lub fuse.
● Cov yam ntxwv Fusing: Lub melting point ntawm cov khoom melting txiav txim siab fusing yam ntxwv ntawm lub fuse. Cov ntaub ntawv uas tsis tshua muaj melting point tuaj yeem muab cov lus teb ceev ceev, thaum cov ntaub ntawv melting siab muab lub peev xwm ntau dua.
● Mechanical zog: Fuses raug rau cov neeg kho tshuab kev nyuaj siab thaum lub sij hawm ua hauj lwm, yog li cov khoom siv sab hauv yuav tsum muaj lub zog txhua yam txaus los tiv thaiv kev puas tsuaj.
● Thermal stability: fuses ua kom muaj cua sov ntau nyob rau hauv cov xwm txheej dhau los, yog li cov khoom siv sab hauv yuav tsum muaj thermal stability zoo los tiv thaiv kev ua tsis tiav los ntawm overheating.
● Kev ua haujlwm rwb thaiv tsev: Txhawm rau kom muaj kev nyab xeeb, lub fuse vaj tse thiab cov raj tiv thaiv yuav tsum muaj kev ua haujlwm zoo rwb thaiv tsev kom tiv thaiv kom tsis txhob tawg tam sim no.
Cov khoom siv sab hauv ntawm high-voltage fuse muaj kev txiav txim siab ntawm nws qhov kev ua tau zoo. Xaiv cov khoom tsim nyog, ua ke nrog nws cov txheej txheem tsim thiab tsim, tuaj yeem ua kom ntseeg tau tias lub fuse muab kev tiv thaiv kev tiv thaiv overcurrent hauv ntau lub zog.
