Dab tsi yog cov khoom ntawm High Voltage Fuses?

Ua ntej tshaj plaws, peb tuaj yeem saib cov yam ntxwv ntawm high voltage fuses.

Raws li peb paub, kev ua haujlwm ntawmhigh voltage fusesyog tiv thaiv Circuit Court.Ntawd yog, thaum tam sim no nyob rau hauv Circuit Court tshaj li tus nqi teev, cov yaj hauv lub fuse yuav tsim ib hom cua sov kom tawg lub Circuit Court.Yog li ntawd, rau high voltage fusing cov ntaub ntawv, yuav tsum muaj tsawg melting point, yooj yim rau extinguish arc yam ntxwv.Feem ntau suav nrog tooj liab, nyiaj, zinc, txhuas, txhuas tin alloy thiab lwm yam ntaub ntawv.Vim tias cov ntsiab lus melting ntawm cov ntaub ntawv no sib txawv, cov ntaub ntawv sib txawv xav tau rau cov dej sib txawv.Lawv melting kub sib haum mus rau 1080 ℃, 960 ℃, 420 ℃, 327 ℃ thiab 200 ℃ feem.

Cov lus qhia rau kev siv cov khoom sib txawv no yog raws li hauv qab no:
1. Lub melting point ntawm zinc, txhuas, lead-tin alloy thiab lwm yam hlau yog kuj tsawg, tab sis lub resistivity yog loj dua.Yog li ntawd, kev siv fuse cross-sectional cheeb tsam yog loj dua, cov hlau vapor generated thaum fusing tsis conducive rau extinguish arc.Feem ntau siv hauv Circuit Court hauv qab 1kV.
2. Tooj thiab nyiaj muaj cov ntsiab lus siab melting, tab sis me me resistivity thiab zoo hluav taws xob thiab thermal conductivity.Yog li ntawd, kev siv fuse cross-sectional cheeb tsam yog me me, cov hlau vapor generated thaum fusing yog tsawg, yooj yim rau extinguish arc.Yuav siv tau nyob rau hauv high voltage, high tam sim no Circuit Court.Txawm li cas los xij, yog tias qhov tam sim no loj dhau, qhov kub ntawm lub sijhawm ntev yog siab dhau, yooj yim rau kev puas tsuaj rau lwm cov khoom hauv lub fuse.Txhawm rau ua kom cov fuse yaj sai sai, nws yuav tsum ntws los ntawm qhov loj dua tam sim no, txwv tsis pub nws yuav ncua lub sijhawm fuse, uas tsis zoo rau cov khoom siv tiv thaiv.Txhawm rau tshem tawm qhov tsis txaus no, tin lossis txhuas pellet feem ntau welded rau ntawm tooj liab lossis nyiaj yaj kom txo qhov kub ntawm melting thiab txhim kho kev tiv thaiv ntawm cov yaj.
