Xa kuthelekiswa neiinjini ezilinganayo, umazibuthe osisigxinaiinjini ze-synchronouszineengenelo ezicacileyo. Banokusebenza okuphezulu, amandla aphezulu, izikhombisi zokusebenza ezilungileyo, ubungakanani obuncinci, ubunzima obulula, ukunyuka kobushushu obuphantsi, iziphumo ezibalulekileyo zobugcisa, kunye nokuphucula umgangatho wegridi yamandla. izinto, ukusebenzisa ngokupheleleyo umthamo wegridi yamandla ekhoyo, ukonga utyalo-mali kwigridi yamandla, kunye nokusombulula ngcono "ihashe elikhulu nenqwelo encinci" kwizixhobo zombane.
01.Ukusebenza kakuhle kunye namandla factor
Xa i-motor asynchronous isebenza, i-rotor winding ithatha inxalenye yamandla ombane ukusuka kwigridi yamandla yokuvuselela, edla amandla ombane wamandla. Le nxalenye yamandla ombane ekugqibeleni idliwe kwi-rotor winding njengobushushu. Le lahleko ibalelwa malunga ne-20-30% yelahleko iyonke yemoto, enciphisa ukusebenza kakuhle kwemoto. I-rotor excitation current iguqulelwa kwi-stator winding njenge-inductive current, eyenza i-current ingene kwi-stator winding lag emva kombane wegridi yamandla nge-engile, okubangela ukuhla kwamandla e-motor. Ukongeza, ukusuka ekusebenzeni kakuhle kunye namandla factor curves ofumazibuthe osisigxina iimotor synchronouskunye neenjini ze-asynchronous (Umfanekiso 1), kunokubonwa ukuba xa izinga lomthwalo (= P2 / Pn)
Emva kokuba umazibuthe osisigxina efakwe kwi-rotor yemagnethi esisigxina ye-synchronous motor, umazibuthe osisigxina usetyenziselwa ukuseka i-rotor magnetic field. Ngethuba lokusebenza okuqhelekileyo, i-rotor kunye ne-stator magnetic field igijima ngokuhambelanayo, akukho mbane owenziweyo kwi-rotor, kwaye akukho lahleko lokumelana ne-rotor. Oku kukodwa kunokunyusa ukusebenza kwemoto nge-4% ~ 50%. Ekubeni akukho nto ivuselelayo yangoku kwi-hydromagnetic motor rotor, i-stator winding ingaba ngumthwalo ococekileyo ochasayo, okwenza i-motor factor factor iphantse ibe yi-1. 1), kunokubonwa ukuba xa izinga lomthwalo wemagnethi esisigxina ye-synchronous motor i>20%, ukusebenza kwayo ngokufanelekileyo kunye nokusebenza kwamandla akutshintshi kakhulu, kwaye ukusebenza kakuhle ku> 80%.
02. Ukuqala ikhabhinethi
Xa i-asynchronous motor iqaliswa, i-motor ifuneka ukuba ibe ne-torque enkulu ngokwaneleyo, kodwa ukuqala okwangoku akukukhulu kakhulu, ukunqanda ukuhla kwamandla ombane ngokugqithisileyo kwigridi yamandla kwaye kuchaphazele ukusebenza okuqhelekileyo kwezinye iinjini kunye nezixhobo zombane. idityaniswe kwigridi yamandla. Ukongeza, xa isiqalo sangoku sisikhulu kakhulu, i-motor ngokwayo iya kuchaphazeleka ngamandla ombane amaninzi. Ukuba iqalwa rhoqo, kukwakho nengozi yokutshisa i-winding. Ke ngoko, uyilo lokuqala lwee-asynchronous motors luhlala lujongana nengxaki.
Iimotor ezisisigxina zemagnethi ezihambelanayo ngokubanzi zikwasebenzisa ukuqala okungafaniyo. Ekubeni i-rotor winding ingasebenzi xa i-magnetic esisigxina ye-synchronous motor isebenza ngokuqhelekileyo, xa uyila i-motor magnetic esisigxina, i-rotor winding inokufikelela ngokupheleleyo kwiimfuno ze-torque ephezulu, umzekelo, i-torque yokuqala inyuka ukusuka kumaxesha angama-1.8. i-asynchronous motor ukuya kumaxesha angama-2.5, okanye nangaphezulu, eyisombulula ngcono into "yehashe elikhulu elitsala inqwelo encinci" kwizixhobo zamandla.
3. Ukunyuka kobushushu bokusebenza
Ekubeni i-rotor winding ine-curly flowing xa i-asynchronous motor isebenza, kwaye lo mbane ugqitywe ngokupheleleyo ngendlela yamandla obushushu, ubushushu obukhulu buya kuveliswa kwi-rotor winding, eya kwandisa ubushushu bemoto kwaye ichaphazele inkonzo. ubomi bemoto. Ngenxa yokusebenza okuphezulu kweenjini zemagnethi ezisisigxina, akukho lahleko yokuchasa kwi-rotor winding, kwaye kuncinci okanye phantse akukho nto isebenzayo kwi-stator winding, eyenza ukuba ubushushu bemoto bunyuke kwaye bandise ubomi benkonzo yemoto. 4. Impembelelo ekusebenzeni kwegridi yamandla
Ngenxa yamandla asezantsi emoto ye-asynchronous, i-motor ithatha inani elikhulu langoku elisebenzayo ukusuka kwigridi yamandla, okukhokelela kwisixa esikhulu sangoku esisebenzayo kwigridi yamandla, izixhobo zokuguqula kunye nezixhobo zokuvelisa amandla, ezithi zinciphise umgangatho wegridi yamandla kunye nokwandisa umthwalo kwigridi yamandla, izixhobo zokuguqula amandla kunye nezixhobo zokuvelisa amandla. Ngelo xesha, umbane osebenzayo usebenzisa inxalenye yamandla ombane kwigridi yamandla, izixhobo ze-transformer kunye nezixhobo zokuvelisa amandla, okubangelwa ukusebenza okuphantsi kwegridi yamandla kunye nokuchaphazela ukusetyenziswa kakuhle kwamandla ombane. Kwakhona ngenxa yokusebenza kakuhle okuphantsi kwe-asynchronous motor, ukuze kuhlangatyezwane neemfuno zamandla aphumayo, kuyimfuneko ukufunxa amandla ombane amaninzi kwigridi yamandla, ukwandisa ngakumbi ukulahlekelwa kwamandla ombane kunye nokwandisa umthwalo kwigridi yamandla.
Akukho ukunyuswa kwangoku kwe-induction yangoku kwi-rotor yemagnethi esisigxina, i-motor ine-high power factor, ephucula umgangatho wegridi yamandla kunye nokuphelisa isidingo sokufakela umxhasi kwigridi yamandla. Kwangaxeshanye, ngenxa yokusebenza kakuhle kwemagnethi esisigxina, amandla ombane nawo ayagcinwa.
