Emikhiqizweni yezimboni yanamuhla, ama-motor kagesi asetshenziswa kabanzi. Izinhlobo ezahlukene, izinhlobo zama-voltage kanye namazinga e-voltage ama-motor kagesi avela ngokungenamkhawulo. Okulandelayo incazelo emfushane yezizathu zokusebenza kwesigaba esisodwa kanye nezinyathelo zokuvimbela.
Ukuhlukaniswa kwama-motor
Ama-motor kagesi angahlukaniswa ngama-DC motors, ama-motor asynchronous kanye nama-motor asynchronous ngokwezakhiwo ezahlukene kanye nezimiso zokusebenza. Ama-motor asynchronous angahlukaniswa futhi abe ama-motor asynchronous amagnet ahlala njalo, ama-motor asynchronous asynchronous kanye nama-motor asynchronous asynchronous. Ama-motor asynchronous angahlukaniswa abe ama-motor angenisayo kanye nama-motor a-AC commutator. Ama-motor angenisayo ahlukaniswe futhi abe ama-motor asynchronous anezigaba ezintathu, ama-motor asynchronous anezigaba esisodwa kanye nama-motor asynchronous anezimbobo ezimnyama. Ama-motor a-AC commutator ahlukaniswe futhi abe ama-motor achungechunge lwesigaba esisodwa,Ama-motor e-AC ne-DC anezinjongo ezimbili kanye nama-motor okuxosha.
Izingozi ezibangelwa ukusebenza kwesigaba esisodwa kwama-motor angenazo izigaba ezintathu
Ama-motor angenazo izintambo anezigaba ezintathu anezindlela ezimbili zokuxhuma: uhlobo lwe-Y kanye nohlobo lwe-Δ. Uma i-motor exhunywe ku-Y isebenza ngesigaba esisodwa, ugesi esigabeni esinqanyuliwe uba yi-zero. Ugesi wesigaba wezinye izigaba ezimbili uba ugesi womugqa. Ngesikhathi esifanayo, uzobangela ukukhukhuleka kwephuzu elingu-zero futhi ugesi wayo wesigaba nawo uzokwanda.
Uma imoto enezintambo zohlobo lwe-Δ inqanyuliwe ngaphakathi, imoto ishintsha ibe yizintambo zohlobo lwe-V ngaphansi kwesenzo sokunikezwa kwamandla kwezigaba ezintathu, futhi ugesi wezigaba ezimbili ukhuphuka ngokuphindwe ka-1.5. Uma imoto enezintambo zohlobo lwe-Δ inqanyuliwe ngaphandle, ilingana nogesi wezigaba ezimbili oxhunywe ngokulandelana kanye neqembu lesithathu lama-windings axhunywe ngokuhambisana phakathi kwama-voltage emigqa emibili. Ugesi kulezo ezimbiliama-windingsokuxhunywe ochungechungeni akukashintshi. Ugesi owengeziwe weqembu lesithathu uzokhushulwa ngokuphindwe ka-1.5.
Ngamafuphi, uma injini isebenza ngesigaba esisodwa, ugesi wayo wokugoqa uyanda ngokushesha, futhi isivalo sokugoqa nesensimbi sishisa ngokushesha, sishise i-insulation yokugoqa bese sishisa i-motor winding, okuthinta imisebenzi evamile yokukhiqiza. Uma indawo esendaweni ingalungile, indawo ezungezile izoqongelela. Kunezinto ezivuthayo ezingadala kalula imililo futhi zibangele imiphumela emibi kakhulu.
Izimbangela zokusebenza kwesigaba esisodwa semoto kanye nezinyathelo zokuvimbela
1. Uma injini ingakwazi ukuqala, kuba nomsindo wokubhonga, futhi igobolondo likhuphuka izinga lokushisa noma ijubane lehla kakhulu ngesikhathi sokusebenza, futhi izinga lokushisa lenyuka, ukunikezwa kwamandla kufanele kunqanyulwe ngokushesha futhi imbangela yokwehluleka kufanele itholakale ngokucophelela. Thola ukuthi isimo esingenhla sibangelwa ukuntuleka kwesigaba.
2. Uma umugqa wamandla wesekethe eyinhloko umncane kakhulu noma ubhekene nomonakalo wangaphandle, ukunikezwa kwamandla emoto kwezigaba ezintathu kuzobangela ukusebenza kwesigaba esisodwa ngenxa yokusha kwesigaba noma ukushaya kwamandla angaphandle. Umthamo wokuthwala ophephile womugqa wamandla oyinhloko wemoto uphindwe izikhathi eziyi-1.5 kuya kwezingu-2.5 kunomthamo wamandla olinganiselwe wemoto, futhi umthamo wokuthwala ophephile womugqa wamandla uhlobene eduze nendlela yokubeka umugqa wamandla. Ikakhulukazi uma uhambisana noma uhlangana nepayipi lokushisa, isikhawu kumele sibe ngaphezu kwama-50cm. Umthamo wokuthwala ophephile wentambo yamandla ongasebenza isikhathi eside ekukhuphukeni kwezinga lokushisa elingu-70°C ngokuvamile ungahlolwa yincwadi kagesi. Ngokusho kokuhlangenwe nakho kwangaphambilini, umthamo wokuthwala ophephile wezintambo zethusi ungu-6A ngemilimitha yesikwele, kanti owezintambo ze-aluminium ungu-4A ngemilimitha yesikwele. Ngaphezu kwalokho, amalunga okushintshana ethusi ne-aluminium kufanele asetshenziswe lapho kuhlanganiswa izintambo zethusi ne-aluminium, ukuze kugwenywe ukushiswa phakathi kwezinto zethusi ne-aluminium futhi kuthinte ukumelana kwamalunga.
3. Ukulungiselelwa okungalungile kweswishi yomoya noma isivikelo sokuvuza kungabangela ukusebenza kwemoto ngesigaba esisodwa. Uma ukulungiselelwa kweswishi yomoya kuncane kakhulu, kungase kube ngenxa yokuthi ugesi wamanje mkhulu kakhulu ukushisa oxhumana nabo bangaphakathi beswishi yomoya, okuholela ekutheni ukumelana kokuxhumana kwesigaba kukhulu kakhulu, okwakha ukusebenza kwemoto yesigaba esisodwa. Ugesi wamanje olinganiselwe weswishi yomoya kufanele ube izikhathi ezingu-1.5 kuya kwezingu-2.5 kunogesi olinganiselwe wemoto. Ngaphezu kwalokho, ngesikhathi sokusebenza kwemoto, kufanele kuqashwe ukuthi ukulungiselelwa kweswishi yomoya kuncane kakhulu, noma ikhwalithi yeswishi yomoya ngokwayo iyinkinga, futhi kufanele kushintshwe iswishi yomoya efanele.
4. Umugqa wokuxhumanisa phakathi kwezingxenye ezikukhabhinethi yokulawula uyasha, okungase kubangele ukuthi imoto isebenze ngesigaba esisodwa. Izizathu zokusha komugqa wokuxhumanisa yilezi ezilandelayo:
① Umugqa wokuxhuma uncane kakhulu, uma ugesi we-overload motor ukhuphuka, ungase ushise umugqa wokuxhuma. ② Izixhumi kuzo zombili izinhlangothi zomugqa wokuxhuma azixhumene kahle, okubangela ukuthi umugqa wokuxhuma ushise ngokweqile, ngaleyo ndlela kushiswe umugqa wokuxhuma. Kukhona umonakalo omncane wezilwane, njengokukhuphuka kwamagundane phakathi kwemigqa emibili, okubangela ukujikeleza okufushane phakathi kwemigqa nokushiswa komugqa wokuxhuma. Isixazululo yilesi: ngaphambi kokuqala umsebenzi ngamunye, ikhabhinethi yokulawula kufanele ivulwe ukuze kuhlolwe ngokucophelela ukuthi umbala womugqa ngamunye wokuxhuma ushintshile yini, nokuthi isikhumba sokuvikela sinezimpawu zokusha yini. Umugqa wamandla ufakwe kahle ngokuya ngomthamo womthwalo wemoto, futhi isixhumi sixhunywe ngokuya ngezidingo zenqubo.
Ukuguqulwa
Ekwakhiweni, kumele silandele ngokuqinile izincazelo zezinqubo ezahlukene zokwakha ukuqinisekisa ikhwalithi yokufaka. Ukugcinwa njalo kwemishini ehlukahlukene kanye nokuhlolwa njalo nokulungiswa ngesikhathi sokusebenza kuzogwema ukulahlekelwa okungadingekile nezingozi ezibangelwa ukusebenza kwemoto kwesigaba esisodwa.
