NH fuse yog dab tsi?
Dab tsi yog cov txheej txheem ntawm NH fuse ceramic lub cev?
NH fuse yog ib hom high-voltage, high-power fuse uas feem ntau siv hauv kev lag luam thiab kev lag luam hluav taws xob. NH stands rau "Neozed-Hochspannungs" uas txhais mus rau "Neozed high-voltage" ua lus Askiv. Cov fuses no yog tsim los pab tiv thaiv overcurrent tej yam kev mob nyob rau hauv high-voltage hluav taws xob systems.
NH fuse ceramic lub cev yog ib feem ntawm lub fuse uas muaj cov khoom siv fuse thiab muab cov khoom siv hluav taws xob thiab hluav taws xob rwb thaiv tsev tsim nyog rau kev ua haujlwm zoo ntawm fuse. Cov txheej txheem tsim khoom ntawm NH fuse ceramic lub cev feem ntau suav nrog cov kauj ruam hauv qab no:
1-Kev npaj cov ntaub ntawv raw: Cov khoom siv tseem ceeb siv los tsim NH fuse ceramic lub cev yog alumina hmoov, av nplaum, thiab feldspar. Cov ntaub ntawv no yog sib tov ua ke nyob rau hauv tej proportions los tsim ib homogenous sib tov.
2-Kev sib sau: Cov sib tov yog tom qab ntawd tsim rau hauv cov duab uas xav tau ntawm NH fuse ceramic lub cev siv ntau yam txuj ci xws li extrusion, nias, lossis casting.
3-Kev ziab: Cov tsim NH fuse ceramic lub cev yog tom qab ntawd qhuav kom tshem tawm cov dej noo seem ntawm cov khoom. Qhov no feem ntau yog ua tiav hauv qhov cub lossis qhov cub ntawm qhov kub thiab txias thiab lub sijhawm.
4-Kev tua hluav taws: NH fuse ceramic lub cev qhuav yog tom qab ntawd raug rho tawm haujlwm hauv qhov cub kub kub kom sinter cov khoom siv thiab muab nws qhov xav tau lub zog thiab cov khoom hluav taws xob.
5-Tiav: NH fuse ceramic lub cev tiav lawm tom qab kuaj xyuas qhov zoo thiab muaj qhov tsis xws luag raug tshem tawm. Lawv kuj yuav raug coated los yog glazed rau kev tiv thaiv ntxiv tiv thaiv ya raws los yog ib puag ncig yam.
Zuag qhia tag nrho, cov txheej txheem tsim khoom ntawm NH fuse ceramic lub cev yog cov txheej txheem nyuaj thiab meej uas yuav tsum tau ua tib zoo tswj qhov kub, siab, thiab lwm yam kev hloov pauv kom ntseeg tau zoo thiab ua haujlwm ntawm cov khoom tiav.
