Yintoni sisigaba ezintathu-current

ubomi bale mihla nanto ngaphandle kombane kunye nezibonelelo ezihlobene nayo. Ukungabikho irhasi yendalo ngokulula uyahlawulwa imithombo ubushushu amafutha eqinileyo, amanzi iyafumaneka, kodwa ngaphandle kombane kufike yokwenene "isiphelo sehlabathi."

Uninzi izityalo namhlanje amandla kudaleke ontlantlu-ntathu ifildi yangoku. Phakathi eziluncedo esidumileyo ezithile lula amalungiselelo kunye nenguqu kamva, ukuthembeka aphezulu kunye nokusebenziseka loyilo ekujongwe kuye Iimoto emgudu munye. -Isigaba Ezintathu yangoku - luhlobo umbane lonke kakhulu.

kwisigaba ezintathu-nkqubo yangoku yiseti kwesigaba ezintathu-iziphaluka yangoku nge frequency efanayo kunye namandla awo kodwa kwatshintsha xa kuthelekiswa bodwa degrees 120 (okanye, yintoni na enye, 1/3 period). Nganye kwezi iziphaluka kuthiwa kwisigaba, ngokulandelelana, zonke zontathu benza kwisigaba ezintathu ngoku.

Iziseko senkolelo zilula: ifreyim yesinyithi lijikeleza into mhlaba otsalayo, ukunqumla amaphaphu umgca. Ngokutsho komthetho yoqheliso magnetic ukufumana ombane, uqhagamshele ezinjengeetheminali zawo umthwalo ngokwaneleyo kwaye adale chain. Ukuba kufuneka ontlantlu-ntathu ngoku, izixhobo ubanzima ngakumbi indlela zibekwe ezintathu isakhelo efana kwatshintsha xa kuthelekiswa omnye komnye degrees 120. Isiphumo sisizukulwana emithathu amandla electromotive (EMF). Kwamazinga ephehla isantya ujikelezo njalo.

Ukuziqhelisa, ukuphunyezwa yi isuntswana eyahlukileyo imfundiso. phase-amathathu yangoku kumisa izixhobo ezikhethekileyo - generator. Kwezi sigaba iziphaluka ngokubhijela ayinakutshintshwa (thelekisa kunye theory), kwaye ngendlela ethile akhiwe kwi izibonda stator (inxalenye ezisisigxina kumatshini). A batshintshana Imagnethi yomhlaba into eyenziwe ivili. Torque ibika amandla wamanzi kwizikhululo aphehla amandla, injini umphunga izityalo amandla enyukliya njalo njalo.

Enye iimpawu isekethe usebenzise ontlantlu-ntathu ngoku, ilele ngokumandla umsebenzisi-icala ezintathu kuphela okanye ezine iingcingo - isigaba emithathu cala. Kuyenzeka ukuba ukufikelela yinkqubo yokuqhagamshelwa wenkunkuma jiko - nkwenkwezi okanye unxantathu.

uqhagamshelo Star kuthetha ukuba iziphelo zontathu engathi idibane abakwindawo eqandeni. Ngokusekelwe umthetho Kirchhoff kaThixo, kulandela ukuba sum of imisinga kwindawo (node) nothi, ngoko akukho tyala kwenzeka. Ukususela zero point output zero umqhubi. Le ombane kulinganiswa phakathi umqhubi kunye nayiphi na kumgama ezintathu, amaxesha 1.73 incinane ixabiso ombane phakathi komgca beSifundo ngokwabo. Kwimeko yokuqala, amandla ombane ayi kwisigaba, kunye nemicwe yesibini.

Inkalo ebalulekileyo zo xhulumaniso nkwenkwezi imfuneko ukunqanda ukungalingani sigaba, oko kukuthi, ukulawula, ukuya imisinga eliqukuqela emasebeni kwakukho malunga ngokulinganayo. Loo umahluko omncane kukhokelela engaphephekiyo ukuba ngoku encinane umqhubi cala, kodwa incinci.

A uhlobo ngokupheleleyo Uxhulumaniso engathi generator - unxantathu, ivumela kuziphelisa ezi wire cala. Xa ngokulandelwa nokuphunyezwa kwayo, ekupheleni nganye oko kwayijikeleza liqhagamshelaniswe ekuqaleni olandelayo, enyanisweni, unxantathu, kwaye yombane zisuswe eziphezulu yayo. Ngale ndlela kwesigaba kunye ombane yomgama bayalingana. Kuyimfuneko ukuba esweni imisinga emasebeni lenxaki, ukususela indelelo epheleleyo ye yangoku kwisekethe closed basenokuba ngokugqithiseleyo, ebangela ubushushu yomvelisi kunye nokungaphumeleli kwawo.

Uninzi Iimoto zombane senzelwe lothungelwano ontlantlu-ntathu kuquka indlela yokukhetha indlela ngokubhijela uqhagamshelwano kwenkwenkwezi okanye nxantathu. Oku kukuvumela ukuba ukhethe i ombane yokusebenza. Ngoko, xa odibanisa engathi umthwalo inkwenkwezi rated ombane kuya kubakho amaxesha 1.73 ezincinane kunokuba loo nxantathu.
