Kodi kupopera utoto kungathetse vuto la kufupika kwa magetsi pakati pa kuzungulira kwa ma windings a mota?

Kusinthasintha kwafupipafupi kwa magetsi (inter-turn short circuit) ndi vuto lamagetsi lomwe lingachitike panthawi yopanga, kukonza ndi kugwiritsa ntchito magetsi aliwonse.motaKuzungulira. Ngati vuto la inter-turn short circuit lachitika, kodi lingakonzedwe ndipo ndi njira ziti zomwe ziyenera kutengedwa?

Kupindika ndi kuyika ma winding a mota kungakhale ndi zotsatirapo zoyipa pa insulation layer ya mawaya amagetsi. Kaya ndi waya wamagetsi wopangidwa ndi enamel kapena waya wokutidwa ndi waya wa mica womwe umagwiritsidwa ntchito popanga ma winding, n'kovuta kupewa mavuto otere. Njira yopangira ma winding yopangidwa imakhudzanso kwambiri ubwino wa electromagnetic waya wopangidwa ndi ma winding. Ngati nkhungu si yoyenera ndipo kapangidwe ka mawonekedwe ozungulira sikoyenera, zimabweretsa mavuto akulu pakuwononga insulation panthawi yopangira, zomwe ndi chiopsezo cha mavuto afupiafupi pakati pa ma turn.

Ngati mavuto ofanana achitika mu kuzunguliza musanalowetse utoto, njira zofunika zothetsera kusungunula zitha kutengedwa kuti zichotse ndikuteteza mawaya amagetsi owonongeka; panthawi yokonza kusungunula kuzunguliza, utoto wosungunula ungathandize kwambiri pakulimbitsa kusungunula pakati pa kuzungulira. Zikuoneka kuti Kusungunula kwa waya wamagetsi wovulala kungakwaniritse mokwanira zofunikira pakugwira ntchito kwa kusungunula kwa mota; komabe, ngati kusungunula sikuonekera bwino, kungayambitse kulephera kwamagetsi panthawi yogwira ntchito ya mota, kutanthauza, mavuto afupipafupi pakati pa kuzungulira panthawi yogwira ntchito.

Poyerekeza, vuto la inter-turn short circuit lomwe limachitika mu winding motor isanayambe kugwira ntchito limapezeka kwambiri kudzera mu inter-turn insulation tester, ndipo pali mwayi woti tipeze njira zothanirana ndi vutoli; pamene winding short circuit ikuchitika panthawi yoyesa makina onse kapena kugwiritsa ntchito injini popanda kuthekera kokonza.

Pamene vuto la inter-turn short circuit likuchitika panthawi yogwira ntchito ya mota, vutolo limawonekera ngati vuto la multi-turn insulation, ndipo zina zimakhudzanso coil yonse. Zotsatirapo zoyipa kwambiri zidzakhala pa phase-to-phase insulation ndi ground insulation. Izi zikutanthauza kuti, inter-turn short circuit failure ili ndi zotsatira zazikulu zotumphukira, ndipo mlingo wa inter-turn fault udzakhala woopsa kwambiri. Chitsulo choteteza cha waya wamagetsi chili pafupi kutseguka, kotero kuzungulira konse kuyenera kusinthidwa.

Chifukwa chake, opanga magalimoto ambiri amaika patsogolo kwambiri ukadaulo wokonza makina ozungulira, amayesetsa kuchepetsa ndikuchotsa zoopsa zobisika za zolakwika zoteteza kutentha, ndikukweza kwambiri magwiridwe antchito amagetsi a injini.
