Isigaba ezintathu-circuit

Inkqubo yangoku engundoqo yamkelwa ngoku jikelele ukuba ontlantlu-ntathu iziphaluka, nto leyo banamalungelo eziliqela phezu ezi-.

-Isigaba Three inkqubo ngoku ebizwa imisinga ontlantlu-ntathu eyenziwe yimikhosi ezintathu electromotive kokuba awo efanayo kunye nobungakanani kodwa yasiwa ngokubhekiselele enye kwenye kwisigaba ngo 120⁰ okanye ngethuba okwesithathu.

kwisekethe nganye eyahlukileyo, inkqubo ontlantlu-ntathu obunjalo kuthiwa ukunciphisa isigaba.

Phase lwangoku, oluqhutywa ontlantlu-ntathu yesekethe inokufunyanwa ngokudibanisa ezintathu wenkunkuma efanayo, enika a single-phase ifildi ngoku, rotors, nto leyo bakwimeko ezisisigxina, ukuba ubeka incamathele omnye komnye yaye musa ukutshintsha indawo yazo ngethuba ujikelezo. Kule generator engathi stator ukuba kwenzeka ukusuka kwenye nenye 120⁰ ecaleni ivili le. Phantsi kweemeko ezinjalo, oko kakhulu kucacile ukuba amandla electromotive yomvelisi yesibini iya lusala utshintsho zabo ngokunxulumene wenkunkuma yokuqala 120⁰, ie ixabiso liphezulu amandla electromotive ye kwicala efanayo wokuphehla yesibini uya kuza emva onke plane wenkunkuma luzakujika kwi 120⁰. Umkhosi electromotive yomvelisi wesithathu uya kulibaziseka kuthelekiswa sesibini generator 120⁰.

Kodwa indlela enjalo yokuvelisa ngoku, ezo ontlantlu-ntathu wesiphaluka, ayikho imali kwaye indlela mngeni. Kakhulu lula ezintathu stator engathi sinxulumene iphakheji enye. Loo generator ubizwa ngokuba kwisigaba generator yangoku.

Ngoko ke, lo stator Alternator lwanamhlanje engathi ezintathu (ebizwa ngokuba izigaba generator), kwi 120⁰ kuthelekiswa abangenamakhaya ukuba omnye komnye. Le plane sisigaba ezintathu-generator omiyo plane ezakheke ncam ezi-AC generator.

Ngexesha ukujikeleza engathi plane kuzo zonke badalwe belingana rhoqo kunye namandla awo le amandla electromotive, kodwa azikho ngaxeshanye ukufikelela ubuninzi babo. Sazigqibela ukuba amandla eliphezulu electromotive wenziwa ngexesha lokudlula embindini kwipali esentla le plane ekuqaleni ngokubhijela, kulula ukubona ukuba amandla eliphezulu electromotive ye kwicala elinye kwi-coil yesibini uya kuza emva njengokujikeleza plane ngomhla 120⁰, kwaye eyesithathu - emva kokuqinisekiswa 240⁰ kuthelekiswa kuqala.

Idibanisa isekethe yangaphandle kwisigaba ngasinye wenkunkuma, sinokuyifumana kwisigaba ezintathu yesekethe ngoku ukuba akukho amaqhina oqhagamshelwano akukho umbane, apho nganye imisinga beesekethe eqhiwukileyo enye ukumelana yabo iya kuba alingana awo kodwa yasiwa kwisigaba xa kuthelekiswa nabanye ibuye 120⁰.

To connect wenkunkuma isekethe wangaphandle, kufuneka iingcingo ezintandathu. Ukunciphisa inani ngcingo ukuba aye wesekethe yangaphandle, kuyimfuneko ukuba ukudibanisa coil receiver kunye generator amaqhina oqhagamshelwano ukwenza ngombane kukhatshwa kwindlela ontlantlu-ntathu. Le uxhulumaniso kunokwenziwa ngeendlela ezimbini ezahlukeneyo: unxantathu kunye inkwenkwezi.

Zombini ezi zinto zenza kube lula ukugcina izinto ekudluliseni besikhundla enye evela umbane ezintathu ontlantlu-ntathu ezizimeleyo.

iisekethe phase-ntathu iindebe kube lula ukwenza i elula lula ukuba isixhobo sisebenzise i-injini yombane, leyo kuthiwa emgudu munye. device esisekelwe phezu isicelo kwezi batshintshana emagneti. Kwimeko kwecacileyo, ngaba kukho mhlaba otsalayo ingafumaneka ngokuthi kokutshintsha umazibuthe intsimbi yehashe.

Ukuba endle ibekwe ngendlela ejikelezayo umqhubi lavalwa, nto zibambene nayo esqwini, lo mhlaba otsalayo betshintshana ezidibanayo kwicala umqhubi wayo wesekethe uya wakhuthaza amandla electromotive kulo induction elenza i induction yangoku kule loop ezivaliweyo. Le ukuzibandakanya yangoku nge mhlaba otsalayo le batshintshana umazibuthe coil uya uphendule. ejika kwicala ukujikeleza bubonwa ngokusebenzisa umthetho ngesandla sasekhohlo.

Motors sigaba Ezintathu iqanjwa iinxalenye ezimbini: inxalenye ejikelezayo - i ivili kunye umile - le stator.

Le batshintshana zibuthe wenziwa kwi injini hayi ujikelezo ngomatshini zezibonda zemagneti, kwakunye ithombo alternating current of engathi stator fixed-isigaba.

iisekethe phase-amathathu aye yenzelwe ngomnye iinjineli ezinkulu wombane XIX kunye kwenkulungwane XX ekuqaleni. - injineli Russian MO Dolivo-Dobrovolsky (1862-1919). Le nkqubo iye uvule amathuba kakhulu asetyenziswa kwimizi umbane. Into ebaluleke kakhulu:

• ukonga kumgca kweentambo osuka kwisitishi kubathengi;
• ithuba batshintshana mhlaba otsalayo isetyenziswe Motors ontlantlu-ntathu.
