Ama-stator windings amamotho angaqhumi anezinkinga zesiyingi esifushane, ikakhulukazi okuhlanganisa i-interphase short-circuit (isigaba esifushane sezigaba ezintathu noma ezimbili) kanye ne-inter-turn short-circuit, okuvamise ukubangelwa ukulimala kokufakelwa.Uma kubhekwa lezi zimo, kufanele kuthathwe izinyathelo ezifanele ukubhekana nakho ukugwema ukulimala kwezimoto noma izingozi zokuphepha.
Ukwelashwa kwesifunda esifushane se-Interphase: Uma i-interphase iDemo ye-interphase yenzeka, ngenxa yokuncipha kwenani lokuphenduka kanye noshintsho lwe-slip, i-impedance ye-motor iyancishiswa, futhi okokufaka kwamanje okuvela ekunikezeni amandla kuzokhula ngokushesha.Ukuze ugweme ukugcwala kwemoto kanye nokulimala okumazombezombe, umsebenzi ojwayelekile wokulungisa uwukunqamula ngokushesha ukunikezwa kwamandla, njengokuvala i-breaker circuit noma i-fuse.Uma ukwelashwa kubambezelekile, ama-windings angalimala.Endabeni yesifunda esifushane sesigaba ezimbili noma sesithathu, uma isikhundla sephoyinti lesifunda ngasinye singahambisani, kungase kuholele ekusebenzeni kwe-asymmetrical ye-motor, ukulandelana okungalungile kwamanje kanye nezinye izimo ezingavamile, ezizothinta ukusebenza kanye impilo yemoto.
I-Interturn short circuit treatment: interturn short circuit isho ukwenzeka kwe-short circuit phakathi kwamakhoyili ekujikeni okufanayo.Lokhu kungase kubangele umsindo ongavamile wemoto nokudlidliza.Indlela yokwelapha ngokuyinhloko iwukulungisa injini ngokulungisa noma ngokushintsha ingxenye eyonakele yokusonteka.Ngesikhathi esifanayo, amanye ama-windings nawo adinga ukubhekwa ukuze kuqinisekiswe ukuthi azikho ezinye izinkinga ezingase zibe khona.
Kumele kuqashelwe ukuthi i-interphase short circuit ye-motor-proof-proof motor iyingozi kakhulu, ikakhulukazi icala elenzeka ekupheleni kwe-stator winding.Uma ukujikajika sekufinyeziwe phakathi kokujika, amajika awonakele azoshisa ngokushesha, okungase kuholele ekulimaleni kokufakwa ngaphakathi noma ngisho nokutubeka.Ngaphezu kwalokho, injini ingase ikhiphe umsindo ongajwayelekile, okuwuphawu olusobala.
Ngokuvamile, lapho i-stator winding ye-motor-proof-proof i-short-circuiting, isinyathelo sokuqala ukunqamula ukunikezwa kwamandla ngokushesha ukuze ugweme ukulimala kwemoto noma izinkinga zokuphepha.Kamuva, ukuhlolwa nokugcinwa ngokucophelela kuyadingeka ukuze kulungiswe ingxenye eyonakele yama-winding futhi kuqinisekiswe ukuthi injini ibuyela ekusebenzeni okujwayelekile.Uma isimo sibucayi kakhulu, kungase kudinge ukunakekelwa okujulile nokuxilongwa ochwepheshe ukuze kuqinisekiswe ukusebenza nokuphepha kwemoto.Ngasikhathi sinye, ukuhlolwa nokugcinwa kwe-insulation njalo kubalulekile ukuvimbela izinkinga zesekethe emfishane.
