Ma fuse a 1000V ndi 450A amateteza milu yolipiritsa ya DC yamagulu onse

Ntchito ya mulu wolipiritsa ndi yofanana ndi ya mafuta operekera mafuta pagawo la gasi. Ikhoza kukhazikitsidwa pansi kapena khoma, kuikidwa m'nyumba za anthu (nyumba za anthu, masitolo, malo oimikapo magalimoto, ndi zina zotero) ndi malo oimikapo magalimoto kapena malo opangira ndalama, ndikulipiritsa mitundu yosiyanasiyana ya magalimoto amagetsi malinga ndi milingo yosiyanasiyana yamagetsi. Mapeto olowera a mulu wolipira amalumikizidwa mwachindunji ndi gridi yamagetsi ya AC. Malo otulutsa amagawidwa kukhala AC ndi DC, ndipo ali ndi mapulagi opangira kuti azilipiritsa magalimoto amagetsi.

Chitetezo ndi kudalirika kuyenera kuganiziridwa popanga mulu wolipira. Chifukwa chake, zida zodzitchinjiriza zotetezeka komanso zodalirika ziyenera kugwiritsidwa ntchito poteteza mopitilira muyeso komanso mopitilira muyeso pamapeto olowera, kumapeto kotuluka komanso kulumikizana. Apa tikupangira ma voliyumu apamwamba komanso fuse yaposachedwa kwambiri spfj160 kuchokera ku Littelfuse, mtsogoleri pamakampani opanga ma fuse. Mtunduwu ndi njira yabwino yotetezera dera pakutulutsa kwa DC kwa mulu wolipiritsa ndipo yakhala ikugwiritsidwa ntchito kwambiri popanga mulu wolipiritsa.

Mndandanda wa Spfj ndiye fuse yoyamba yomwe yalembedwa m'kabuku ka certification ul2579 mumakampani amagetsi, yomwe imagwiritsidwa ntchito kuteteza 1000VDC, 70-450a high voltage ndi zida zamakono. Mapangidwe ake ndi mapangidwe ake amakwaniritsa zofunikira za IEC standard 60269-6, ndipo wadutsa VDE 125-450a application certification. Miyezo yokhwima iyi imatha kuwonetsetsa chitetezo cha zida ndi ogwira ntchito, ndikupanga mndandanda wa spfj kukhala chinthu chapadziko lonse lapansi. Zogulitsa za 125-450a zimapereka kukula kwa nyumba za J-Class, zomwe zimatha kupulumutsa malo ambiri opanga zida ndikuchepetsa kwambiri ndalama. Nthawi yomweyo, Littelfuse wa Shiqiang wothandizira atha kuperekanso chofukizira cha 1000VDC chamndandandawu kuti akwaniritse zosowa zapadera za makasitomala ena.

Magetsi ovotera a spfj160 ndi 1000VDC / 600vac ndipo ovotera pano ndi 160A, omwe amatha kukwaniritsa milu yolipiritsa ya DC yamagawo osiyanasiyana. Chovoteledwa kuswa panopa mpaka 200KA@600VAC mwina 20KA@1000VDC , apamwamba oveteredwa kuswa panopa kumatanthauza kuti fusesi sangathe kuphulika pansi pa malire mikhalidwe, kotero ndi otetezeka kwambiri ndi odalirika.
