Mota yamagetsi amphamvu imatulutsa mpweya wa corona. N’chifukwa chiyani mota yamagetsi osinthasintha imachita chimodzimodzi?

Kutuluka kwa Korona kumachitika pamene mphamvu yamagetsi yosagwirizana yapangidwa ndi kondakitala yosasalala. Mozungulira mphamvu yamagetsi yosagwirizana komanso pafupi ndi electrode yokhala ndi radius yaying'ono yokhota, pamene mphamvu yamagetsi ikukwera kufika pamlingo winawake, chifukwa cha ionization ya mpweya, kutuluka kwa magetsi kudzachitika, ndikupanga korona.

Kuchokera ku mikhalidwe yopangira korona, titha kupeza kuti minda yamagetsi yosafanana, ma conductor osasalala, ndi ma voltage okwera mokwanira ndi zinthu zofunika kwambiri popanga korona. Chifukwa chake, korona idzachitika kumapeto kwa ma winding a ma mota amphamvu kwambiri, makamaka kwa ma mota omwe ali ndi voltage yoposa 6kV, korona ya ma winding a stator idzakhala yowonekera bwino, ndipo voltage ikakwera, vuto la korona lidzakhala lalikulu kwambiri. Chifukwa chake, pa ma winding a ma mota amphamvu kwambiri, njira zothanirana ndi korona zimatengedwa pogwiritsa ntchito mawaya apadera amagetsi ndi matepi oletsa kukulunga kunja kwa ma winding coils. Ponena za vuto la korona la ma mota amphamvu kwambiri, kumvetsetsa kwa anthu kuli bwino. Ndiye, nchifukwa chiyani korona imapezekanso m'ma mota amphamvu osinthasintha?

Ma mota a ma frequency osinthasintha amayendetsedwa ndi ma frequency osinthasintha. Mphamvu yamagetsi yotuluka ndi ma frequency osinthasintha si mafunde ofanana ndi a magetsi omwe amaperekedwa pa ma frequency a mafakitale, koma mafunde a sikweya okhala ndi kukwera ndi kutsika kwakukulu. Mafunde apadera a pulse awa amachititsa kuti magetsi olowera a mota azikhala ndi ma peak overvoltages owirikiza kawiri kuposa ma voltage ovotera. Chifukwa cha liwiro lothamanga kwambiri la pulse overvoltage iyi, izi zingayambitse kusafanana kwakukulu pakugawa kwa magetsi a ma windings a ma mota. Ngakhale ma mota ambiri a ma frequency osinthasintha ndi ma mota a low-voltage, njira yapadera yoperekera magetsi imatsimikiza kusafanana kwa magetsi mu ma windings awo.

Kutengera ndi makhalidwe a kuchuluka kwa ma windings ndi kutalika kwa winding iliyonse mu mota, ma windings oyamba ndi omaliza a low-voltage high-power winding motor amanyamula pafupifupi mphamvu zonse za voltage, ndipo nawonso ndi omwe amakhala ndi mavuto ambiri pakuzungulira mota. Komanso, kuchokera ku kusanthula kwa njira yolumikizira ma winding, coil yoyamba yozungulira imawonongeka kwambiri, motero imayang'anizana ndi zoopsa zazikulu. Ichi ndichifukwa chake opanga magalimoto ambiri amapereka chitetezo chapadera pa ma windings oyamba ndi omaliza. Pa ma mota otsika-voltage high-power variable frequency, chifukwa cha mphamvu yosafanana yamunda komanso mphamvu yakuthwa ya pulse, malekezero a ma windings a mota ali ndi zofunikira zoyambira popanga corona. Pofuna kupewa kupanga korona mu mota yosinthasintha, ma windings a mota yosinthasintha ayenera kugwiritsa ntchito waya wapadera wa anti-corona electromagnetic, ndipo njira zapadera zotetezera ziyenera kutengedwa pa ma windings oyamba ndi omaliza.
