Isifunda ezintathu okhombisa

The main isimiso samanje yokutholwa manje emhlabeni kukhona ezintathu okhombisa izifunda, okuyinto kunezimo eziningana ezisivunayo phezu owodwa esigabeni.

Ezintathu okhombisa isimiso samanje ngokuthi ezintathu okhombisa imisinga eyenziwe amabutho amathathu electromotive kokuba amplitude efanayo futhi imvamisa kodwa sigudluke maqondana nomunye isigaba ngu 120⁰ noma phakathi nenkathi okwesithathu.

Isifunda ngasinye ehlukile, uhlelo ezintathu okhombisa kuthiwa ukunciphisa isigaba.

Isigaba samanje, okuyinto eyenziwa ezintathu okhombisa wesifunda ingatholakala ngokuhlanganisa ezintathu generator efanayo, enikeza owodwa esigabeni uhlelo lokwabelana ngamafayela, rotors, okuyinto zisesimweni esinqunyiwe, kuthiwa isandla enamathiselwe nomunye futhi musa ukushintsha isikhundla sabo ngesikhathi ngokushintshana. Kulesi generator stator Windings kuthiwa zenzeka kusukela nomunye by 120⁰ ohlangothini Rotor. Ngaphansi kwezimo ezinjalo, kusobala ngempela ukuthi amandla electromotive generator lesibili isikhathi eside lapho izinguquko abo maqondana generator kuqala ku 120⁰, okusho seqiwe bebutho electromotive ka ohlangothini olufanayo wokuphehla yesibili ethanda ukuza emva zonke Rotor generator izovuleka 120⁰. Amandla electromotive generator lwesithathu uzophinde zephuze isihlobo ukuba generator yesibili 120⁰.

Kodwa indlela enjalo lokuveza zamanje, okuyizinto ezintathu okhombisa wesifunda, akuyona iphila ngendlela eyongayo ngokomthetho inselele. Okuningi kulula ezintathu stator Windings axhunyiwe in iphasela single. generator okunjalo kwezinkolo kubizwa ngokuthi wamanje generator isigaba.

Ngakho, stator alternator zamanje has Windings ezintathu (esibizwa i-generator izigaba), at 120⁰ isihlobo abangenamakhaya ukuba nomunye. Rotor kuyinto ezintathu okhombisa generator zamanje nge Rotor ikhipha ezifanayo owodwa esigabeni AC generator.

Phakathi ukujikeleza Windings Rotor zonke badalwa belingana imvamisa futhi amplitude we force electromotive, kepha kanyekanye ukuthola izinga eliphelele yabo. Uma kucatshangwa ukuthi amandla esiphezulu electromotive ekhiqizwa ngesikhathi ukudlula maphakathi isigxobo enyakatho Rotor ekuqaleni emazombezombe, kulula ukubona ukuthi amandla esiphezulu electromotive isiqondiso ofanayo ikhoyili yesibili ethanda ukuza emva ukujikeleza Rotor ku 120⁰, kanti eyesithathu - emva ukuvula 240⁰ isihlobo ngezokuqala. '

Ixhuma i wesifunda zangaphandle ngamunye isigaba generator, thina ukuthola ezintathu isigaba wesifunda yamanje abangenalo oxhumene kungekho uxhumano kagesi, lapho ngamunye ehlukile wesifunda imisinga ngesikhathi esifanayo ukumelana labo liyoba belingana amplitude kodwa sigudluke esigabeni isihlobo komunye nomunye futhi ngezinye 120⁰.

Ukuze uxhume i-generator kangaka wesifunda zangaphandle, kudingeka izintambo eziyisithupha. Ukuze unciphise inani izintambo ukuthi ukuya wesifunda zangaphandle, kubalulekile ukuxhuma ikhoyili umamukeli bese generator kuhlobene indlela kagesi oluhambisana ohlelweni ezintathu okhombisa. Lokhu uxhumano kungenziwa ngezindlela ezimbili ezihlukene: unxantathu inkanyezi.

Bobabili compounds enze kube nokwenzeka ukuba bayolanda ukudluliselwa amandla efanayo kusukela ezizimele ezintathu ezintathu okhombisa ugesi.

Ezintathu okhombisa izifunda kwenza ukuba ukudala elula ezanele umshini ukuba usebenze motor kagesi, okuthiwa indlela. kudivayisi yakhe esekelwe isicelo ligijima kazibuthe. Endabeni elula, amandla kazibuthe ingatholakala ligijima uzibuthe ukhamba.

Uma ngabe inkambu ibekwe endaweni ujikelezisa umqhubi avaliwe, nasezinsikeni eksisi emuva, amandla kazibuthe ngokushintshana yayo intersecting ohlangothini wesifunda umqhubi ntombazane amandla electromotive therein lokungeniswa ekhiqiza i zamanje lokungeniswa kule iluphu avaliwe. Lokhu uxhumana wamanje amandla kazibuthe ujikelezisa uzibuthe ikhoyili sizophenduka. uphendulela isiqondiso ujikeleza kunqunywa usebenzisa ngesandla sokunxele umthetho.

Three Isigaba izinjini zenziwe ngezinto ezimbili: ingxenye ujikelezisa - Rotor kanye umile - the stator.

I ujikelezisa kazibuthe ekhiqizwa e injini Akukhona Ukujikeleza mechanical zezingongolo kazibuthe, futhi ngesikhathi ukugeleza kushintshana samanje fixed-isigaba stator Windings.

Ezintathu okhombisa izifunda saklanywa omunye onjiniyela enkulu kagesi XIX and zakuqala XX leminyaka. - unjiniyela Russian MO nge Dolivo-Dobrovolsky (1862-1919). Lolu hlelo ivule amathuba okukhulu nokuba angasetshenziswa ezimbonini kukagesi. Into ebaluleke kakhulu:

• ukonga wiring umugqa ohlanganisa esiteshini kumthengi;
• kungenzeka ujikelezisa kazibuthe isicelo ezintathu okhombisa izinjini.
