Kodi zosungunulira za injini zimatsimikiziridwa ndi kukula kwa magetsi kapena magetsi?

Ndi insulationzakuthupiya injini yotsimikiziridwa ndi kukula kwa magetsi kapena magetsi?

Insulation zakuthupindi chinthu chofunikira kwambiri pazinthu zamagalimoto. Ma motors okhala ndi ma voliyumu osiyanasiyana amakhala ndi kusiyana kwakukulu pamapangidwe otsekera a ma windings awo ndi zigawo zawo zazikulu. Mwachitsanzo, kamangidwe ka kutchinjiriza kwa high-voltage motor ndi low-voltage motor windings ndizosiyana kwambiri. .


Zida zotetezera, yomwe imadziwikanso kuti dielectrics, ndi zipangizo zomwe zimakhala ndi resistivity yapamwamba kwambiri komanso kusayenda bwino kwambiri. Amagwiritsidwanso ntchito pazinthu zamagalimoto chifukwa cha kusayenda bwino kwawo. M'zinthu zamagalimoto, kudzera muzitsulo zotetezera, mbali imodzi, mawaya a conductive amagwirizanitsidwa ndi zigawo zina. Kupatukana, kumbali ina, ndiko kulekanitsa mfundo zosiyanasiyana za mzere wa conductive, monga inter-turn insulation ndi inter-phase insulation. Zida zosiyanasiyana zotsekera zimathanso kukhala ndi zinthu zosiyanasiyana monga kuthandizira, kukonza, kuzimitsa kwa arc, kukana kwa mildew, kuteteza ma radiation ndi kukana dzimbiri.

Kuwotcha kwa ma windings a motor ndi chiwonetsero cha konkire cha kuwonongeka kapena kutha kwa ntchito yotsekera. Ndiye, kodi ntchito yotchinjiriza ya mota yawonongeka chifukwa cha mafunde akulu kapena mphamvu yayikulu?

Mapiritsi a injini akachuluka kwambiri, kuchulukiraku kumapangitsa kuti kukana kwa mafunde kuchuluke ndikuyambitsa kutentha kwakukulu. Kutentha kopangidwa ndi injini kudzatayidwa kudzera mu kutsekereza. Kutentha kukafika pamlingo wina, kapangidwe kazinthu zotsekerako zimasintha bwino, monga mota. Zofunikira pakugwira ntchito kwamakalasi osiyanasiyana otchinjiriza monga B, F, ndi H omwe akuphatikizidwa patebulo amafanana ndi kutentha kwakukulu komwezipangizo zotetezeraakhoza kupirira.

Pamapindidwe a mota, zofunikira zotsekera pakati pa kutembenuka ndi kutembenuka, pakati pa magawo osiyanasiyana a mota yamagawo angapo, komanso pakati pa kondakitala ndi nthaka. Pamene mphamvu yamagetsi yamagetsi ikukwera, mphamvu yamagetsi yamagetsi imakhalanso yokwera, zomwe zingakhale zosavuta Ganizirani izi ngati ma capacitors osiyanasiyana. Ngati voteji pakati pa capacitors ndi okwera kwambiri, zimabweretsa vuto la kusweka capacitor, ndiko kuti, kulephera kutchinjiriza kwa galimoto yokhotakhota pansi, pakati mokhota ndi pakati magawo.

Kuchokera pazomwe zili pamwambapa, titha kumvetsetsa kuti ngakhale mphamvu yamagetsi yamagetsi yamagetsi ndi yaying'ono, magetsi otsekera a ma windings ndi okwera, chifukwa chake njira yapadera yotsekera iyenera kugwiritsidwa ntchito kuwonetsetsa kuti magetsi agalimoto amakwaniritsa zofunikira. ; pamene otsika-voltage galimoto, chifukwa kutchinjiriza voteji ndi wokwera Choncho, kusankha zipangizo insulating n'kosavuta, koma kachulukidwe panopa, mpweya wabwino ndi dissipation kutentha ndi zinthu zofunika kuonetsetsa magetsi ntchito galimoto. The panopa ndi voteji wa galimoto ndi zikoka zosiyanasiyana pazipangizo zotetezerandipo ziyenera kuganiziridwa nthawi yomweyo.
