Indlela yoNyango yeSekethe eMfutshane kwiStator Wining of Explosion-Proven Motor

I-stator windings yee-motor-proof-proof motors zineengxaki ze-short-circuit, ikakhulukazi ezibandakanya i-interphase short-circuit (isigaba sesithathu okanye isigaba esifutshane-isigaba esifutshane) kunye ne-inter-turn short-circuit, edla ngokubangelwa ngumonakalo wokugquma.Xa ujongene nezi meko, amanyathelo afanelekileyo kufuneka athathwe ukujongana nayo ukuphepha umonakalo wemoto okanye iingozi zokhuseleko.

I-Interphase yonyango olufutshane lwesiphaluka: Xa i-interphase i-short circuit iyenzeka, ngenxa yokuncipha kwenani lokujika kunye nokutshintshwa kwe-slip, i-impedance ye-motor iyancitshiswa, kwaye igalelo langoku elivela kumbane liya kwanda ngokukhawuleza.Ukuze kuthintelwe ukugqithiswa kwemoto kunye nomonakalo ojikelezayo, umsebenzi oqhelekileyo wokulondoloza kukunqumla ngokukhawuleza ukunikezelwa kwamandla, njengokuvala i-breaker circuit okanye i-fuse.Ukuba unyango lulibazisekile, i-windings inokonakala.Kwimeko yesigaba sesibini okanye sesithathu sesiphaluka esifutshane, ukuba indawo yesigaba ngasinye sesekhethi emfutshane ayihambelani, kunokukhokelela ekusebenzeni kwe-asymmetrical yemoto, ulandelelwano olubi lwangoku kunye nezinye iimeko ezingaqhelekanga, eziya kuchaphazela ukusebenza kunye ubomi bemoto.

I-interturn short circuit unyango: i-interturn short circuit ibhekisela kwisehlo sesiphaluka esifutshane phakathi kweekhoyili kwi-winging efanayo.Oku kunokubangela ingxolo engaqhelekanga yemoto kunye nokungcangcazela.Indlela yonyango ikakhulu kukulungisa i-motor ngokulungisa okanye ukubuyisela indawo eyonakeleyo yokujija.Kwangaxeshanye, amanye amajiko-jiko nawo kufuneka ajongwe ukuqinisekisa ukuba azikho ezinye iingxaki ezinokubakho.

Kufuneka kuqatshelwe ukuba i-interphase short circuit ye-motor-proof proof yeyona nto inzima kakhulu, ngakumbi imeko eyenzeka ekupheleni kwe-stator winding.Nje ukuba ujiko lufutshane phakathi kojiko, ujiko olonakeleyo luya kutshisa ngokukhawuleza, okunokukhokelela kumonakalo wokugquma okanye ukudinwa.Ukongeza, i-motor inokuvelisa ingxolo engaqhelekanga, nto leyo engumqondiso ocacileyo.

Ngokubanzi, xa i-stator winding ye-motor-proof-proof is short-circuiting, inyathelo lokuqala kukunqumla umbane ngokukhawuleza ukuphepha umonakalo wemoto okanye iingxaki zokhuseleko.Emva koko, ukuhlolwa ngokucophelela kunye nokugcinwa kuyadingeka ukulungisa inxalenye eyonakalisiweyo ye-winding kwaye uqinisekise ukuba i-motor ibuyela ekusebenzeni okuqhelekileyo.Ukuba imeko inzima kakhulu, inokufuna ukugcinwa okunzulu kunye nokuxilongwa kweengcali zokuqinisekisa ukusebenza kunye nokhuseleko lwemoto.Kwangaxeshanye, ukuvavanywa rhoqo kunye nokugcinwa kwe-insulation kubalulekile ukukhusela iingxaki zesekethe emfutshane.
