Poyerekeza ndima asynchronous motors, maginito okhazikikama synchronous motorskukhala ndi ubwino woonekeratu. Ali ndi mphamvu zambiri, mphamvu zambiri, zizindikiro zogwira ntchito bwino, kukula kochepa, kulemera kochepa, kutentha kwapansi, kukwera kwakukulu kwa luso, komanso kupititsa patsogolo luso la gridi yamagetsi. zinthu, kugwiritsa ntchito mphamvu ya gululi yamagetsi yomwe ilipo, kupulumutsa ndalama mu gridi yamagetsi, komanso kuthetsa bwino zochitika za "kavalo wamkulu ndi ngolo yaying'ono" pazida zamagetsi.​
01.Kuchita bwino ndi mphamvu
Pamene injini ya asynchronous ikugwira ntchito, kuzungulira kwa rotor kumatenga mbali ya mphamvu yamagetsi kuchokera ku gridi yamagetsi kuti ikhale yosangalatsa, yomwe imawononga mphamvu ya gridi yamagetsi. Gawo ili la mphamvu yamagetsi pamapeto pake limadyedwa mukuyenda kozungulira ngati kutentha. Kutayika kumeneku kumakhala pafupifupi 20-30% ya kutayika kwathunthu kwa mota, zomwe zimachepetsa mphamvu yagalimoto. The rotor excitation panopa ndi n'kukhala stator mapiringidzo monga inductive panopa, zomwe zimapanga panopa kulowa stator makhotedwe lag kuseri kwa mphamvu gululi voteji ndi ngodya, chifukwa mu kuchepa mphamvu chinthu galimoto. Komanso, kuchokera dzuwa ndi mphamvu factor curves wamaginito okhazikika ma synchronous motorsndi ma asynchronous motors (Chithunzi 1), zikhoza kuwoneka kuti pamene kuchuluka kwa katundu (= P2 / Pn) ndi
Pambuyo maginito okhazikika ophatikizidwa mu rotor ya okhazikika maginito synchronous galimoto, maginito okhazikika ntchito kukhazikitsa rotor maginito munda. Panthawi yogwira ntchito bwino, rotor ndi stator magnetic field zimayenda mofanana, palibe mphamvu zowonongeka mu rotor, ndipo palibe kutayika kwa rotor. Izi zokha zitha kuwonjezera mphamvu zamagalimoto ndi 4% ~ 50%. Popeza palibe chisangalalo chapano chomwe chimapangidwa mu hydromagnetic motor rotor, mafunde a stator akhoza kukhala katundu wokhazikika, kupangitsa mphamvu yamagetsi yamagetsi pafupifupi 1. Kuchokera pakuchita bwino komanso mphamvu zamagetsi zamakina okhazikika amotor synchronous motor ndi asynchronous motor (Chithunzi 1), zitha kuwoneka kuti kuchuluka kwa magalimoto okhazikika a maginito osinthika ndi> 20%, magwiridwe ake ogwiritsira ntchito komanso mphamvu zogwiritsira ntchito sizisintha kwambiri, ndipo magwiridwe antchito ndi> 80%.
02. Kuyambitsa nduna
injini ya asynchronous ikayamba, injiniyo imayenera kukhala ndi torque yayikulu yokwanira, koma poyambira siili yayikulu kwambiri, kuti mupewe kutsika kwamagetsi ochulukirapo mu gridi yamagetsi ndikusokoneza magwiridwe antchito amtundu wina wamagetsi ndi zida zamagetsi. olumikizidwa ku gridi yamagetsi. Kuphatikiza apo, pomwe choyambira chimakhala chachikulu kwambiri, injiniyo yokha imakhudzidwa ndi mphamvu yamagetsi yochulukirapo. Ngati ayambika pafupipafupi, palinso ngozi yowotcha mopiringa. Chifukwa chake, mapangidwe oyambira a ma asynchronous motors nthawi zambiri amakumana ndi vuto.
Maginito okhazikika a ma synchronous motors nthawi zambiri amagwiritsa ntchito poyambira. Popeza mafunde a rotor sagwira ntchito ngati maginito okhazikika a synchronous motor akugwira ntchito moyenera, popanga maginito okhazikika, mafunde a rotor amatha kukwaniritsa zofunikira za torque yayikulu, mwachitsanzo, ma torque oyambira akuchulukira kuchokera nthawi 1.8. injini ya asynchronous mpaka nthawi 2.5, kapena yokulirapo, yomwe imathetsa vuto la "kavalo wamkulu kukoka ngolo yaying'ono" mu zida zamagetsi.
3. Kutentha kwa ntchito
Popeza mafunde a rotor ali ndikuyenda kwaposachedwa pamene injini ya asynchronous ikugwira ntchito, ndipo izi zimatha kudyedwa ngati mphamvu ya kutentha, kutentha kwakukulu kumapangidwa mu mafunde a rotor, zomwe zidzawonjezera kutentha kwa injini ndikukhudza ntchitoyo. moyo wa injini. Chifukwa chakuchita bwino kwambiri kwa maginito okhazikika a maginito, palibe kutayika kwa ma rotator, ndipo pamakhala pang'ono kapena pafupifupi palibenso mphamvu yamagetsi pamayendedwe a stator, zomwe zimapangitsa kutentha kwa injini kutsika ndikuwonjezera moyo wautumiki wagalimoto. 4. Zokhudza kugwira ntchito kwa gridi yamagetsi
Chifukwa cha mphamvu yochepa ya injini ya asynchronous, galimotoyo imatenga mphamvu zambiri zowonongeka kuchokera ku gridi yamagetsi, zomwe zimapangitsa kuti pakhale mphamvu zambiri zomwe zimagwiritsidwa ntchito mu gridi yamagetsi, zida za thiransifoma ndi zida zopangira magetsi, zomwe zimachepetsanso mphamvu. mtundu wa gridi yamagetsi ndikuwonjezera katundu pa gridi yamagetsi, zida za thiransifoma ndi zida zopangira magetsi. Panthawi imodzimodziyo, mphamvu yowonongeka imagwiritsa ntchito mbali ya mphamvu yamagetsi mu gridi yamagetsi, zipangizo za transformer ndi zipangizo zopangira magetsi, zomwe zimapangitsa kuti magetsi azikhala ochepa komanso amakhudza kugwiritsa ntchito mphamvu zamagetsi. Komanso chifukwa cha mphamvu yochepa ya injini ya asynchronous, kuti ikwaniritse zofunikira za mphamvu zamagetsi, m'pofunika kuti mutenge mphamvu zambiri zamagetsi kuchokera ku gridi yamagetsi, kuwonjezera kutayika kwa mphamvu yamagetsi ndikuwonjezera katundu pa gridi yamagetsi.
Palibe kulowetsedwa kwaposachedwa mumagetsi okhazikika amagetsi ozungulira, injiniyo imakhala ndi mphamvu yayikulu, yomwe imapangitsa kuti gridi yamagetsi ikhale yabwino ndikuchotsa kufunikira kokhazikitsa chowongolera mu gridi yamagetsi. Nthawi yomweyo, chifukwa champhamvu kwambiri yamagetsi okhazikika amagetsi, mphamvu yamagetsi imapulumutsidwanso.
