Indlela ukuxhuma motor 380 kuya 220: schema

Kunezimo lapho imishini ukalwe nganoma 380 volts, kudingeka ukuxhuma kunethiwekhi ekhaya 220 V Kusukela injini awukaqali, udinga ukushintsha ke kwezinye imininingwane. Lokhu kungenziwa kalula wedwa. Ngisho naphezu kweqiniso lokuthi nekusebenta ukuze wehlise kancane le ndlela kuyafaneleka.

Ezintathu okhombisa nasezakhini isigaba motors

Ukuze uqonde ukuthi ukuxhuma motor kagesi nge volts 380 220, sifunda ukuthi kusho ukuthini amandla at 380 volts.

Ezintathu okhombisa motors kunezimo eziningi kuqhathaniswa single phase yasendlini. Ngakho-ke, basuke kabanzi embonini. Futhi amandla hhayi kuphela, kodwa futhi kahle. Futhi inqobo ikhoyili ukuqala futhi capacitors. Lokhu lula design mshini. Ngokwesibonelo, lo nogada inhlamvu we edluliselwe esiqandisini ilandelela vrublyus eziningi kanjani emazombezombe. A ezintathu okhombisa motor kule isici okudingeka akudingekile.

Lokhu kufezwa ngezinkathi zezikhathi izigaba ezintathu, phakathi kwesikhathi lapho siphenduka ngaphakathi stator kazibuthe.

Kungani 380?

Lapho le nsimu uzungeza ngaphakathi stator, Rotor futhi ihamba. Revolutions musa uqondane amahlanu inethiwekhi Hertz ngenxa yokuthi ngaphezulu Windings, inani izingongolo kuyinto enhle kakhulu, kanye ngenxa yezizathu ezihlukahlukene, ukushelela kwenzeka. Lezi zinkomba asetshenziselwa motor kushaft isivinini isiqondiso.

Zonke izigaba ezintathu abe ukubaluleka 220 V Nokho, umehluko phakathi yimuphi bobabili, nganoma isiphi isikhathi kuyoba sihluke 220. Ngakho uthole 380 volts. Okungukuthi, injini isebenzisa 220 ukusebenza, kuyilapho kukhona shift isigaba, ingenye namashumi amabili degrees.

Ngenxa yendlela yokuxhuma motor volts 380 kuya 220 ngokuqondile engenakwenzeka, esinalo ukusebenzisa amaqhinga. I capacitor ubhekwa ngendlela elula. Lapho isitsha sihamba isigaba, lona wamuva sishintshwe degrees ayisishiyagalolunye. Okungenani eyodwa namashumi amabili, yena akezi, kwanele ukuqala futhi ugijime nenjini ezintathu okhombisa.

Indlela ukuxhuma motor 380 kuya 220

Ukuqalisa imisebenzi udinga ukuba baqonde indlela ukwakha Windings. Ngokuvamile, umzimba ivikelwe izindlu kanye wiring elise ngaphansi kwalo. Ngemva kokususa ke, kudingeka uhlole okuqukethwe. Ngokuvamile ungathola umdwebo wiring. Ukuze uxhume motor kunethiwekhi senzeka 380-220, usuke isetshenziswa ngendlela izinkanyezi. Imikhawulo emazombezombe kukhona at iphuzu ovamile, okuthiwa hlangothi. Isigaba fed uhlangothi.

"Inkanyezi" kuyomelwe bashintshe. Ukuze wenze lokhu, kumele motor Windings ixhumeke uhlobo oluhlukile - ngesimo unxantathu, hlanganisa them enisemikhawulweni komunye nomunye.

Indlela ukuxhuma motor 380 kuya 220: schema

Isikimu kungenzeka kanje:

• voltage amapayipi lisetshenzisiwe lwesithathu emazombezombe;
• ke ikhoyili voltage lokuqala egcina epholisayo nge shift isigaba lamadigri ayisishiyagalolunye;
• ikhoyili wesibili sizothinta umehluko voltage.

Kuyaqondakala ukuthi shift isigaba izovuleka degrees ayisishiyagalolunye amane nanhlanu. Ngenxa yalokhu Ukujikeleza iyunifomu ngeke zisebenze. Ngaphezu kwalokho, ukuma sesibili emazombezombe ngeke sinusoidal. Ngakho-ke, ngemva motor ezintathu okhombisa exhunywe kwi 220 volts aphumelele, ngeke isebenze ngaphandle kokuba amandla ukulahlekelwa. Ngezinye izikhathi, ngisho izinti kushaft nabongci ukuphotha.

umthamo Ukusebenza

Ngemva kuyodingeka ekuqaleni-up yokudayela okusheshayo umthamo cha, kusukela ukunyakaza ukumelana kuyoba abangelutho. Ukuchithela amandla ayo unciphise ukumelana lapho wamanje ngeke adlule. Ukuze sikhethe kahle ka yokusebenza umthamo qala-up kwasekuqaleni kufanele inake ukuthi voltage yokusebenza ye capacitor kumele kakhulu kuyendlulela 220 volts. Okungenani kufanele kube 400 V Kuyadingeka ukuba banake izintambo ukuthi imisinga yayiklanyelwe owodwa esigabeni inethiwekhi.

Nge incane kakhulu esihlahleni isitsha yokusebenza okunamathelayo, ngakho ukusheshisa kokuqala isetshenziselwa ke.

umthamo Ukusebenza nalo ehlaselwe lezi zinto ezilandelayo:

• Enamandla ngokwengeziwe motor, aba maningi capacitor okuzisholo edingekayo. Uma inani 250 W, tando suffice futhi amashumi amaningana microfarads. Nokho, uma amandla kuyoba ephakeme, futhi ukubaluleka okuzisholo angabhekwa ngamakhulu. Capacitors kangcono ukuthenga ifilimu, ngoba uyoba amandla angeziwe ukuqedela (ziklanyelwe for okuqhubekayo, kunokuba AC, futhi akukho ushintsho engase aqhume).
• I emikhulu ijubane injini, futhi ihlelo idinga ngenhla. Uma uthatha injini at 3000 ngomzuzu futhi 2.2 kW, ibhethri kwakuzodingeka microfarads 200 kuya 250. Futhi lokhu kubaluleke kakhulu.

Kodwa, lo umthamo incike umthwalo.

Isigaba sokugcina

Kuyaziwa ukuthi i-motor kagesi volts 380 kuya 220 izosebenza kangcono uma kwenzeka ukuthi amagugu voltage etholakala nge alinganayo. Ngenxa yalesi ikhoyili uxhumeke kwinethiwekhi, akudingeki uthinte, kodwa ezingaba kukalwa ngesikhathi abanye ababili.

Ngo motor indlela has zayo reactance. Kuyadingeka ukuchaza ubuncane lapho ke uzoqala spin. Ngemva kwalokho, ihlelo ukwanda kancane kancane ukuze nje bonke Windings baye equalized.

Kodwa lapho injini spin up, kungase kwenzeke ukuthi ukulingana woniwa. It proiskhodtit ngoba uhudula ukunciphisa. Ngakho-ke, ngaphambi ohlanganisa motor kagesi volts 380 220 futhi ukukulungisa, kubalulekile nokulinganisa abakuzuzile iyunithi ngesikhatsi kokuhlinzwa.

Voltage sibe phezu 220 V Niyabo, eqinisekisa esitebeleni kokuzalela oxhumana nabo, futhi kwakungekho ukulahlekelwa amandla noma okweqile. Okuhle kunakho konke ukuthi usuke kwenziwa ezikhumulweni ekhethekile nge bolts isilungisiwe. Uma exhunywe kwi-motor volts 380 kuya 220 kwenzeka lokho kwabase-nemingcele ezidingekayo ku iyunithi futhi agqoke bezinhlamvu, kanye izintambo zidlulela izinhlangothi kophawu zenjoloba.

Yini enye zenzeka nokuthi singamukelwa kanjani ekuxazululeni izinkinga

Ngokuvamile, ngemva kokuba umkhandlu wembula ukuthi singene kushaft uzungeza ohlangothini olungafanele ofuna. udinga ukushintsha isiqondiso.

Ngenxa yalesi ikhoyili lwesithathu ixhunyiwe ngokusebenzisa capacitor ukuba terminals isikulufa we stator yesibili emazombezombe.

Kwenzeka ukuthi ngenxa yomsebenzi yesikhathi eside Ngomsindo injini kwenzeka ngokuhamba kwesikhathi. Nokho, umsindo ohluke njengoba kuqhathaniswa indumo uxhumano ayilungile. Kwenzeka ngokuhamba kwesikhathi injini vibration. Ngezinye izikhathi ngisho banamandla ukujikisa Rotor. Ngokuvamile lokhu kubangelwa ukuwohloka kwamangqamuzana amabombo, ngenxa okuyinto kukhona isikhala esiningi futhi umsindo. Ngokuhamba kwesikhathi, lokhu kungase kuholele wenza umcimbi, futhi kamuva - ngokonakalisa injini izingxenye.

Kungcono ukugwema lokhu, kungenjalo indlela ngeke baba yize. Vele esikhundleni amabombo emisha. Khona-ke motor izothatha iminyaka eminingi ezayo.
