Kutheni le nto i-winding ye-motor-phase motor itshisa xa isigaba singekho? Ingakanani yangoku enokwenziwa uqhagamshelwano lwenkwenkwezi kunye nedelta?

Kuyo nayiphi na i-motor, nje ukuba eyona nto isebenzayo ye-motor ingagqithisi i-motor rated, i-motor ikhuselekile, kwaye xa i-current idlula i-current rated current, i-motor windings isengozini yokutshiswa.Kwiimpazamo zenqanaba lesithathu, ukulahleka kwesigaba luhlobo oluqhelekileyo lwesiphoso, kodwa ngokuvela kwezixhobo zokukhusela iimoto, iingxaki ezinjalo ziye zagwenywa ngcono.

Nangona kunjalo, xa kukho ingxaki yokulahleka kwesigaba kwi-motor yesigaba sesithathu, i-windings iya kutshiswa rhoqo ngexesha elifutshane. Iindlela ezahlukeneyo zokudibanisa zinemigaqo eyahlukeneyo yokutshiswa kwee-windings. I-motor windings yendlela yokudibanisa i-delta iya kuba nengxaki yokulahleka kwesigaba. Xa kusenzeka, esinye isigaba sokujika siya kutshiswa kwaye ezinye izigaba ezibini azichanekanga; ngelixa ujiko oludityaniswe lenkwenkwezi, ukujika-jika kwezigaba ezibini kuya kutshiswa kwaye esinye isigaba siya kuba sinjalo.

 

Kumajiko-jiko atshileyo, esona sizathu singundoqo kukuba umsinga omelana nawo udlula umsinga obekiweyo, kodwa ukuba mkhulu kangakanani na lo msinga yingxaki uninzi lwabasebenzisi be-intanethi abayixhalabele kakhulu. Wonke umntu uzama ukuyiqonda ngokobungakanani ngokusebenzisa iifomula zokubala ezithile.Kukho neengcali ezininzi eziye zenza uhlalutyo olukhethekileyo kulo mba, kodwa ekubaleni okuhlukeneyo kunye nohlalutyo, kukho rhoqo izinto ezingenakulinganiswa, eziya kukhokelela ekuphambukeni okukhulu kwangoku, okuye kwabuye kwaba sisihloko sengxoxo eqhubekayo.

Xa i-motor iqala kwaye iqhuba ngokuqhelekileyo, i-alternating current yesigaba sesithathu ngumthwalo we-symmetrical, kwaye imisinga yesigaba sesithathu ilingana nobukhulu kwaye ingaphantsi okanye ilingana nexabiso elilinganisiweyo.Xa ukuqhawulwa kwesigaba esisodwa kwenzeka, i-current of one or two-phase lines iya kuba yi-zero, kwaye i-current yemigca yesigaba esisele iya kwanda.Sithatha umthwalo ngexesha lokusebenza kombane njengomthwalo olinganisiweyo, kwaye sihlalutye imeko yangoku ngokusemgangathweni ukusuka kubudlelwane bokusabalalisa ukuchasana nokuphefumula kunye ne-torque emva kokungaphumeleli kwesigaba.

 

Xa i-motor edibeneyo ye-delta isebenza ngokuqhelekileyo kumaxabiso alinganisiweyo, isigaba sangoku seqela ngalinye le-windings li-1 / 1.732 ngamaxesha akhoyo (umgca wangoku) we-motor.Xa isigaba esinye sinqanyuliwe, i-winding phases ezibini idibaniswe kwi-series kwaye esinye isigaba sidibaniswe ngokufanayo.Umbane ojikelezayo ophethe umbane womgca wedwa uya kufikelela ngaphezu kwe-2.5 amaxesha akhoyo, okuya kubangela ukuba i-winging itshiswe ngexesha elifutshane kakhulu, kunye nezinye izigaba ezibini ezijikelezayo zincinci kwaye zisemgangathweni jikelele.

Kwimoto edityaniswe yinkwenkwezi, xa isigaba sinqanyuliwe, ezinye izigaba ezimbini zomoya ziqhagamshelwe kuthotho kunye nombane,

Xa umthwalo uhlala ungatshintshi, i-current yesigaba esinqanyuliweyo i-zero, kwaye i-current yezinye i-wind-phase-fase windings inyuka ibe ngaphezu kokuphindwe kabini i-current rated current, ibangela ukuba i-winding phases ezibini zigqithise kwaye zitshise.

Nangona kunjalo, ukusuka kuhlalutyo lwenkqubo yonke yokulahleka kwesigaba, izinto ezahlukahlukeneyo ezifana ne-windings eyahlukeneyo, umgangatho ohlukeneyo womgangatho we-windings, kunye neemeko zangempela zomthwalo ziya kubangela utshintsho olunzima lwangoku, olungenakubalwa kwaye luhlalutywe kwiifomyula ezilula. Singakwazi kuphela Uhlalutyo olurhabaxa lwenziwa kwezinye iindawo zomda kunye neendlela ezifanelekileyo.
