Kwimveliso yanamhlanje yamashishini, iimotor zombane zisetyenziswa kakhulu.Iindidi ezahlukeneyo, iifom zombane kunye namanqanaba ombane weenjini zombane zivela ngokungapheliyo.Oku kulandelayo yinkcazo emfutshane yezizathu zokusebenza kwesigaba esisodwa kunye namanyathelo okuthintela.
Ukuhlelwa kweenjini
Iimotor zombane zinokwahlulwa zibe ziinjini zeDC, iimotor ezilinganayo kunye neemotor ezihambelanayo ngokwezakhiwo ezahlukeneyo kunye nemigaqo yokusebenza.Iimotor ze-synchronous zinokwahlulwa zibe ziimotor ze-synchronous zemagnethi ezisisigxina, iimotor ezi-synchronous zokungafuni kunye ne-hysteresis synchronous motors.Iinjini zeAsynchronous zinokwahlulwa zibe ziimotor induction kunye neemotor AC commutator.Iinjini zokungeniswa zikwahlulahlulwe ngokwamanqanaba amathathu eenjini zeasynchronous, iimotor ezinenqanaba elinye kunye neemotor ezinomthunzi we-asynchronous motors.Iimotor ze-AC commutator zahlulwe ngakumbi kwiimotor zenqanaba elinye,Iinjini ze-AC kunye ne-DC ezineenjongo ezimbini kunye neenjini zokugxotha.
Iingozi ezibangelwa kukusebenza kwesigaba esinye sesigaba sesithathu se-asynchronous motors
Izigaba ezintathu ze-asynchronous motors zineendlela ezimbini zocingo: u-Y-uhlobo kunye no-Δ-uhlobo.Xa i-motor edibeneyo ye-Y isebenza kwisigaba esisodwa, okwangoku kwisigaba esinqanyuliweyo ngu-zero.Imisinga yesigaba sezinye izigaba ezibini iba yimisinga yomgca.Kwangaxeshanye, iya kubangela i-zero point drift kwaye i-voltage yesigaba sayo nayo iya kunyuka.
Xa i-motor ene-Δ-type i-wiring inqanyuliwe ngaphakathi, i-motor iyatshintsha ibe yi-V-type wiring phantsi kwesenzo sombane wesigaba sesithathu, kwaye inqanaba lesibini langoku linyuka ngamaxesha angama-1.5.Xa i-motor ene-Δ-type i-wiring inqanyuliwe ngaphandle, ilingana ne-winging phases ezibini ezidityanisiweyo kwi-series kunye neqela lesithathu le-wingings elidityaniswe ngokuhambelana phakathi kweendlela ezimbini zombane.Umsinga kwezi zimbiniamajiko-jikoidityaniswe kuthotho ihlala ingatshintshi.Ixesha elongezelelweyo leqela lesithathu liya kwandiswa ngamaxesha angama-1.5.
Ukushwankathela, xa i-motor isebenza kwisigaba esinye, ukujikeleza kwayo kwangoku kunyuka ngokukhawuleza, kwaye i-winging kunye ne-casing casing ishushu ngokukhawuleza, itshisa i-insulation ejikelezayo kwaye itshise i-motor winding, echaphazela imisebenzi yesiqhelo yemveliso.Ukuba imeko yendawo yesayithi ayilungile, indawo engqongileyo iya kuqokelelana.Kukho izinto ezinokutsha ezinokubangela umlilo ngokulula kwaye zibangele iziphumo ezibi kakhulu.
Izizathu zemoto yesigaba esisodwa kunye namanyathelo okuthintela
1.Xa i-motor ingakwazi ukuqalisa, kukho isandi esikhalayo, kwaye igobolondo inokunyuka kweqondo lokushisa okanye isantya siyancipha kakhulu ngexesha lokusebenza, kwaye ukunyuka kweqondo lokushisa kuyanda, umbane kufuneka unqunyulwe ngokukhawuleza kwaye unobangela wokungaphumeleli zifunyenwe ngononophelo.Qinisekisa ukuba imeko engentla ibangelwa ukungabikho kwesigaba.
2.Xa umgca wamandla wesiphaluka esiphambili uncinci kakhulu okanye udibana nomonakalo wangaphandle, ukunikezelwa kwamandla ombane wesigaba sesithathu kuya kubangela ukusebenza kwesigaba esisodwa ngenxa yokutshiswa kwesigaba okanye ukubetha kwamandla angaphandle.Umthamo okhuselekileyo wokuthwala umgca wamandla oyintloko we-motor yi-1.5 ukuya kuma-2.5 amaxesha alinganiswayo ngoku yemoto, kunye nomthamo okhuselekileyo wokuthwala umbane wombane uhambelana ngokusondeleyo kwindlela yokubeka umgca wamandla.Ngokukodwa xa ihambelana okanye idibanisa nombhobho wokushisa, ikhefu kufuneka libe likhulu kune-50cm.Umthamo okhuselekileyo wokuthwala wentambo yamandla enokuthi ihambe ixesha elide kwi-70 ° C yokunyuka kobushushu kunokujongwa ngokubanzi ngencwadana yesikhokelo sombane.Ngokwamava adlulileyo, umthamo okhuselekileyo wokuthwala iingcingo zobhedu yi-6A nge-square millimeter, kwaye iingcingo ze-aluminium ziyi-4A nge-square millimeter.Ukongezelela, i-copper-aluminium transition joints kufuneka isetyenziswe xa i-copper-aluminium wire joints, ukwenzela ukuba ugweme i-oxidation phakathi kwezinto zobhedu-aluminiyam kunye nokuchaphazela ukuxhathisa ngokubambisana.
3. Ukucwangciswa okungafanelekanga kokutshintsha umoya okanye umkhuseli wokuvuza kunokubangela ukusebenza kwesigaba esinye semoto.Ukuba uqwalaselo lokutshintsha komoya luncinci kakhulu, lunokuba ngenxa yonikezelo lwamandla lwangoku lukhulu kakhulu ukutshisa abafowunelwa bangaphakathi bokutshintsha umoya, okukhokelela ekuxhathiseni koqhagamshelwano lwesigaba kukhulu kakhulu, kusenza inqanaba elinye lokusebenza kwemoto.Umjelo olinganisiweyo wokutshintsha umoya kufuneka ube ngama-1.5 ukuya kuma-2.5 amaxesha ombane olinganisiweyo wemoto.Ukongezelela, ngexesha lokusebenza kwe-motor, kufuneka kubekwe iliso ukuba ukulungiswa kokutshintshwa komoya kuncinci kakhulu, okanye umgangatho wokutshintsha umoya ngokwawo uyingxaki, kwaye ukutshintshwa komoya ofanelekileyo kufuneka kuthathelwe indawo.
4.Umgca wokudibanisa phakathi kwamacandelo kwikhabhinethi yokulawula utshiswa, enokubangela ukuba i-motor iqhube kwisigaba esisodwa.Izizathu zokuvutha komgca woqhagamshelo zezi zilandelayo:
① Umgca woqhagamshelo uncinci kakhulu, xa i-motor overload yangoku inyuka, inokutshisa umgca wokudibanisa.② Iziqhagamshelo kwiziphelo zombini zomgca woxhulumaniso zinxibelelana kakubi, zibangela ukuba umgca wokudibanisa ugqithise, ngaloo ndlela utshisa umgca wokudibanisa.Kukho umonakalo omncinci wezilwanyana, ezifana nokunyuka kweempuku phakathi kwemigca emibini, kubangela isiphaluka esifutshane phakathi kwemigca kunye nokutshisa umgca wokudibanisa.Isisombululo kukuba: ngaphambi kokuqala umsebenzi ngamnye, ikhabhinethi yokulawula kufuneka ivulwe ukuba ihlolisise ngokucophelela ukuba umbala womgca wokudibanisa ngamnye utshintshile, kwaye ingaba ulusu lwe-insulation lunamanqaku okutshisa.Umgca wamandla uxhotyiswe ngokufanelekileyo ngokuhambelana nomthwalo wangoku wemoto, kwaye ikhonkco ixhunyiwe ngokweemfuno zenkqubo.
Ukugqobhoza
Ekwakhiweni, kufuneka sithobele ngokuthe ngqo inkcazo yeenkqubo ezahlukeneyo zokwakha ukuqinisekisa umgangatho wofakelo.Ukugcinwa rhoqo kwezixhobo ezahlukeneyo kunye nokuhlolwa rhoqo kunye nokulungiswa ngexesha lokusebenza ngokuqinisekileyo kuya kuphepha ilahleko engadingekile kunye neengozi ezibangelwa kukusebenza kwesigaba esinye semoto.
