Indlela kokuxhuma ezintathu okhombisa motor 220V inethiwekhi: amathiphu

Ngokuvamile kunesidingo kulelikhaya noma ngesikhathi umsebenzi wokulungisa ukwenza ukuxhumana inethiwekhi ezintathu okhombisa motor 220 volts. Lezi amadivayisi ezisebenzela zinamandla of 380 V Kodwa, njengoba sazi, emakhaya iningi amapayipi kuyinto 220V kuphela. Indlela ukuxhuma nenjini ezintathu okhombisa e inethiwekhi 220? Sifunda ngalokhu esihlokweni sethu.

Indlela ukuxhuma nenjini ezintathu okhombisa esigabeni kunethiwekhi eyodwa

Cabangela isibonelo nge umshini wokuthunga. Izinkinga embonini nge uxhumano Yiqiniso, asivelanga. Kodwa isigaba esisodwa motor kagesi kudingeka ushintshe. Ngokwesibonelo, ukushintsha wiring we Windings ukwakha inkanyezi-delta. Yiqiniso, isidingo abanamathela polarity. Ngenxa yalesi ukulungiswa, ke uyokwazi kokuxhuma ezintathu okhombisa motor 220V inethiwekhi.

Amandla motor umshini wokuthunga kuyinto 0.4 kW. Uma kungenzeka ukuthola kokuqala metallized capacitors MBTT, MBGO MBGO noma nge 50 noma 100 MF capacitance kanye voltage zokusebenza 450 kuya kwangu-600, bese kuba izinkinga ngeke ukuqala. Noma kunjalo, kungase kubize kakhulu. Ngakho-ke kungcono ufune enye izixazululo "ezishibhile" inkinga.

Kule ndaba ingase ibe nomphumela wesikhashana ezengeziwe capacitor electrolytic. Kufanele basebenze ukuze nje ababili noma abathathu imizuzwana, engasekho. Phela, umsebenzi wakhe kuyadingeka kuphela ukusebenzisa motor. Khona-ke lona wamuva izobe seyisebenza ngo ezimbili-isigaba imodi, futhi ulahlekelwe kuze kube amandla nengxenye. I stock ngakho Nokho, kungenziwa enikeziwe. Phela, lo nokulahlekelwa okufanayo kwamandla sizoba lapho esebenza capacitor isigaba-kwethunzi.

Ububi indlela futhi isixazululo

Abantu abaningi bayazi ukuthi capacitor electrolytic ngokushesha okukhulu sekuqala ukufudumala kunethiwekhi AC. I electrolyte kuwo amathumba Kuqhuma. Prakthiza selukhombisile ukuthi lokhu kwenzeke isikhathi imizuzwana eyishumi kuya nanhlanu. Kodwa uma epholisayo ukufaka imizuzwana eyodwa nengxenye kuphela usebenzisa ukumelana encane, idivayisi ngeke konakale, njengoba isikhathi elifudumele-up wamane ngeke.

Ngo imishini yokuwasha for short-term inkinobho ukusetshenziswa PNVS. Yena emithathu prong. Ababili babo waba nesifo sokuwa, futhi umuntu owenza ngaphandle kwalo. Ngenxa zokugcina contact epholisayo ivuliwe futhi ayisavumelekile ngemva kokuqedwa ngokucindezela.

Voltage phezu capacitors electrolytic akufanele kube ngaphansi kuka-450V. Ngakho-ke, lesi umthamo ezoshayelwa kusukela capacitors amaningi afakwe ebhokisini zokuzivikela. Le ndlela uxhumano practice ukuba sidlule siye sabonisa ukusebenza yayo. Nokho, ucwaningo yayiqhutshelwa kuphela motors kagesi, amandla okuyinto engaphansi kW. Ukuze izinjini ezinamandla kakhudlwana, cishe lokho kuzodinga ukufakwa Resistor encane nge capacitor nge komkhawulo wamanje kanye le ezidingekayo amandla ukushabalalisa.

Indlela yesibili

Cabanga indlela exhunyiwe indlela ezintathu okhombisa squirrel yezinyoni motor e owodwa esigabeni amanethiwekhi.

Ekusebenteni, ngisho ne lesikahle yesigaba-ukuguquguquka capacitor umthamo torque engu ngeke idlule amaphesenti amathathu nanhlanu we bokuzisholo. Lisuselwa yokuthi egeleza ngokusebenzisa zamanje ikhoyili, isigaba-sigudluke mayelana nezinye Windings. Ngakho-ke, amandla kazibuthe stator kudala kwenye ingxenyana ngaphezu eyodwa ukuthi uzungeza Rotor ohlangothini oyifunayo.

Uphiko kwakhiwa ijikeleziswa okuhlukile amabhuleki Rotor, ekunciphiseni torque kushaft ngakho ukuchitha amandla ngokubeka amalahle motor ezivamile futhi wire kazibuthe. Kodwa uma uvala emazombezombe, torque luyanda amaphesenti amane nanye. Futhi uma ushintsha isiqondiso zamanje kuwo bese uxhuma futhi, khona-ke ukwandisa nakakhulu, futhi ungaba amaphesenti amahlanu nesishiyagalombili.

Indlela sithuthukise inqubo

Le nqubo nokwenza kungenzeka hhayi kuphela ngenxa ushintsho isiqondiso ukuzungeza yezingxenye. Futhi uphendulela isinxephezelo nakweminye imikhakha Windings, okuyinto luqondane esiqondisweni futhi awahlanganyeli ukujikeleza Rotor. Qala injini futhi kuthuthukisa ukusetshenziswa capacitors ezimbili isigaba-kwethunzi.

umthamo wabo kumele kube okufanayo. izinkomba ezinjalo ibalwe ifomula. Basuke uhlolwa ekukaleni voltage phezu Windings futhi kufanele sikubonise imiphumela efanayo.

voltages Equal kungenziwa oppositely exhunywe parallel nge umugqa ashabalala.

Indlela ukuxhuma AC motor kwenethiwekhi 220 volts

Hams ngokuvamile kudingeka sisebenzise izinjini enixoxa ngalo. Ngakho-ke, indlela kokuxhuma ezintathu okhombisa motor 220V inethiwekhi, kubaluleke kakhulu ukwazi. Sesiyazi ukuthi akudingekile ukuba inethiwekhi ezintathu okhombisa salokhu. Kungcono ukuxhuma lwesithathu kokugwingciza capacitor isigaba-kwethunzi.

Ukuze operation evamile motor capacitance ushintsho, unikezwa inombolo linemibhikisho. In practice, lokhu isimo kunzima ukuphumelela. Kusukela isikhundla elise by ezimbili isigaba: injini kufaka umthamo ukuziqalela futhi bavunyelwe ngenkathi usebenza. yena bashintshele ukusebenza kwimodi manual.

I capacitor kuphela uhlobo ephepheni, kanye namasistimu okusebenza yayo voltage kumele kube izikhathi ezingaphezu kwesisodwa nesigamu ngaphezu kwezihlalo amapayipi voltage. Ukushayela imoto elungisa isiqalo capacitor oluphakeme elula. Lapho kwabangela, inkinobho kushintsha isiqondiso motor ngokushintshana. Kodwa kudingeka sazi izici ekusebenzeni izinjini enjalo. Uma idivayisi emazombezombe ingenzi lutho, lamanje azogeleza esukela amabili ukuba amaphesenti amane we bokuzisholo. Ngakho-ke, kufanele kwebhizinisi lapho uqhuba nge umthwalo umthamo ukusebenza kungancipha. Uma injini ilayishwe, ke sivaliwe, futhi ngiqale ukuphila okusha aphinde Udinga ukufaka i-capacitor isiqalo.

Xhuma motor kunethiwekhi 220V kungaba noma ikuphi, ngisho ezintathu okhombisa. Nokho, ezinye zazo zingase zingasebenzi kahle. Isibonelo double squirrel-yezinyoni Rotor MA. Kodwa uma umdwebo wiring lilungile, futhi ngendlela efanele akhethiwe nemingcele edingekayo capacitors, ukuhamba komsebenzi kuyoba kakhulu. Ngokwesibonelo, ezahlukeneyo eziphumelelayo ziyakujabulela motors indlela A, AO2, ALP, AO, AOL futhi Uad.

Nebubi izindlela ezintathu ukuxhuma

I yokuntula endleleni ngenhla echazwe okulandelayo:

• isigamu ezilahlekile amandla ukalwe ;
• lapho ifakwa amandla kunethiwekhi eyodwa okhombisa akusho ugijime yonke amamodeli we motors kagesi;
• Ukusebenza pad esitsheni lekufanele sisetjentiswe: Nini
• Idling zamanje ageleza ngaphezulu kusukela kwabaneminyaka engamashumi amabili kuya amaphesenti amane we okuzisholo;
• okuzenzakalelayo ukuvala shaqa inqubo qala-up capacitor bese ushintsha izakhi iphepha isivinini xaxa esetshenziswa electrolytic.

Indlela yesine

Ukuphungula lezi yokuntula can, besebenzisa indlela elandelayo. Indlela ukuxhuma nenjini ezintathu okhombisa e inethiwekhi 220?

Voltage ezintathu okhombisa ka ijika ngamunye kugudlukela ngomunye yesithathu kuqhathaniswa nabanye.

Njengoba imvamisa umugqa amahlanu kuya kwangu isikhathi ilingana microseconds amabili. Khona-ke kuyoba eyesithathu ... 6.666 microseconds. Thatha sinusoidal voltage isigaba esisodwa 220V futhi 50 Hz. Uma uyisebenzise ngokusebenzisa wesifunda ukubambezeleka esikhathini lwesithathu, uthola voltage sigudluke okungukuthi amplitude futhi imvamisa ilingane yasekuqaleni. Uma-ke badabula efanayo ukubambezeleka wesifunda, voltage etholwe sigudluke ngu nenkathi yesithathu.

Awazi ukuthi ukuxhuma nenjini ezintathu okhombisa isigaba esisodwa? Isikimu kufanele ihlolisiswe nguwe njengoba kubekiwe ngangokunokwenzeka. Futhi kubukeka kanje.

Mshini kuhlanganisa BP kanye ishayela generator polarity elihle transformer. Okuphakela amandla kuhlanganisa a transformer yesibili, ibhuloho rectifier futhi isimame. Le njini babuthana yesithathu emazombezombe we transformer, a Resistor kanye diode rectifier. Zener diode ivikela izinto zokufaka kusuka ngephutha anda ngenhla voltage kuvunyelwe, okungukuthi, ezingaphezu kuka volts nambili. Izinto egcinwe generator pulses unxande. Ngesikhathi okukhiphayo pulses square ezidla kuya polarity omuhle amahlanu Hertz.

Lapho aguqulayo wamanje ezintathu okhombisa singasebenza ezintathu okhombisa noma ekhethekile ezintathu okhombisa transformer core ngesimo izinduku. Xhuma izakhi ngabanye Kumelwe ube "inkanyezi inkanyezi".

isiphetho

Ngakho, ikhambi umbuzo, indlela kokuxhuma ezintathu okhombisa motor 220V inethiwekhi, mhlawumbe ngezindlela eziningana. Ezinye zazo nzima ukuba kusebenze, kodwa inqubo kuyoba ngcono. izindlela Okunye kulula, kodwa futhi ngeke ngaphandle nemiphumela ethile engathandeki.
