Nthawi zambiri, zomwe zimafunidwa ndi injini poyambira zimakhala zazikulu kuposa zomwe zidavotera pano, zomwe zimakhala pafupifupi ka 6 pakali pano.Pansi pamagetsi oterowo, mota imakhudzidwa kwambiri kuposa momwe imagwira ntchito bwino.Kukhudzidwa kotereku kumawonjezera kutayika kwa mota, kuchepetsa moyo wagalimoto, komanso kuwononga magawo ena mkati mwa makina pomwe mphamvuyo ndi yayikulu kwambiri.Zikatero, anthu amayamba kulabadira kafukufuku wa injini zofewa, ndikuyembekeza kuti injiniyo iyambe bwino komanso bwino kudzera muukadaulo wofananira.
1, injini yofewa yoyambira mfundo
Pazojambula zam'mbuyomu, kafukufuku woyambira mofewa kwambiri amawongolera kuyambika kwa gawo lachitatu la AC asynchronous motor, ndipo kuyambika kofewa kwa mota kumazindikirika pogwiritsa ntchito gawo lachitatu la AC asynchronous motor, lomwe limapereka chitetezo poyambira. ndi kuyimitsa motere.Tekinolojeyi yakhala ikugwiritsidwa ntchito kwambiri m'mafakitale.M'makampani, ukadaulo uwu wagwiritsidwa ntchito m'malo mwa zoyambira za Y/△, ndipo zotsatira zabwino zapezeka.
Three-reverse parallel thyristor (SCR) imatha kusintha voteji ya zoyambira zofewa, ndipo ndiyowongolera voteji ya choyambira chofewa.Pamene thyristor yotsatizana katatu imagwirizanitsidwa ndi dera, imagwira ntchito yolumikizana pakati pa magetsi ndi stator ya galimoto.Mukadina kuti muyambe, voteji mkati mwa thyristor idzawuka pang'onopang'ono, ndipo injiniyo imathamanga pang'onopang'ono pansi pa mphamvu yamagetsi.Liwiro lothamanga likafika pa liwiro lofunikira, thyristor idzatsegulidwa kwathunthu.Panthawiyi, voteji yomwe yadulidwa ndi yofanana ndi magetsi ovotera, omwe sangazindikire M'mikhalidwe yotereyi, galimotoyo imayenda bwino pansi pa chitetezo cha thyristor, chomwe chimapangitsa kuti galimotoyo isavutike kwambiri ndi kuwonongeka, motero kumatalikitsa moyo wautumiki. ya injini ndikusunga motere kuti ikugwira ntchito bwino.

2. Ukadaulo woyambira wofewa wamagalimoto asynchronous
2.1, thyristor AC voteji yowongolera kuyambika kofewa
Magetsi a AC omwe amawongolera kuyambika kofewa kwa thyristor makamaka amasintha njira yolumikizira ya thyristor, kusintha njira yolumikizira yachikhalidwe kukhala yolumikizana ndi ma windings atatu, potero kuzindikira mphamvu ya thyristor molumikizana.Choyambira chofewa cha Thyristor chimakhala ndi kusintha kwamphamvu, kotero ogwiritsa ntchito amatha kupanga zosintha zoyenera pagalimoto molingana ndi zosowa zawo zosiyanasiyana, ndikupanga njira yoyambira yamotoyo kukhala yoyenera pazosowa zawo pogwiritsa ntchito kusintha kofananira.

2.2.Mfundo yosinthira magawo atatu amagetsi a AC owongolera zoyambira zofewa
Magetsi agawo atatu a AC owongolera choyambira chofewa amagwiritsa ntchito mokhazikika pamapindikira amagetsi a AC kuyambitsa mota.Lingaliro logwiritsa ntchito ma curve amtundu wa AC voltage kuti muzindikire kuyambika kofewa kwa mota ngati ili ndilo lingaliro lalikulu la choyambira chofewa.Imagwiritsa ntchito ma trigger atatu mkati mwa mota kulumikiza mota motsatizana, ndikusintha nthawi yotsegulira ndikuwongolera kugunda kwa choyambitsa ndi ngodya yoyambitsa.Pachifukwa ichi, choyimira cholowera cha injini chimatha kusunga ma voliyumu okwanira kuti azitha kuyendetsa injiniyo.injini ikayamba, voteji idzakhala voliyumu yovotera, ndiye kuti zolumikizira zitatu zodulira zidzaphatikizidwa, ndipo galimotoyo imatha kulumikizidwa ku gridi.
3. Ubwino wofewa poyambira pachikhalidwe
"Kuyambira kofewa" sikungochepetsa kwambiri kuyambika kwa njira yopatsira yokha ndikutalikitsa moyo wautumiki wa zigawo zikuluzikulu, komanso kufupikitsa nthawi yamphamvu yagalimoto yoyambira pano, kuchepetsa kuchuluka kwamafuta pagalimoto ndi chikoka. pa gridi yamagetsi, motero kupulumutsa mphamvu yamagetsi ndikutalikitsa moyo wautumiki wagalimoto.Kuphatikiza apo, pogwiritsa ntchito ukadaulo wa "soft start", injini yokhala ndi mphamvu yaying'ono imatha kusankhidwa posankha mota, motero kuchepetsa ndalama zosafunika za zida.Kuyamba kwa nyenyezi kumadalira kusintha mawaya a mawotchi amoto, motero kusintha voteji poyambira.Mphamvu yamagetsi poyambira imachepetsedwa, zomwe zimapangitsa kuti zoyambira zizikhala zazing'ono, ndipo kukhudzidwa kwa basi poyambira kumachepetsedwa, kotero kuti kutsika kwamagetsi kwa basi poyambira kumakhala mkati mwazovomerezeka (pakufunika kuti kutsika kwamagetsi kwa basi sikuyenera kupitirira 10% yamagetsi ovotera).Kuyambika kwa auto-decompression kungathenso kuchepetsa zomwe zikuchitika poyambira, zomwe zimatheka posintha pompopompo yamagetsi ya auto-transformer.
Mwachitsanzo, zofunikira za gululi mphamvu poyambitsa magulu 4 a 36 kilowatts.Yachibadwa ntchito panopa 36 kW galimoto ndi za 70A, ndipo mwachindunji poyambira panopa pafupifupi 5 nthawi yachibadwa panopa, ndiye panopa chofunika magulu anayi a 36 kW Motors kuyamba nthawi yomweyo ndi 1400A;Chofunikira pakuyambitsa nyenyezi kwa gridi yamagetsi ndi nthawi 2-3 yanthawi zonse ndi 560-840A ya gridi yamagetsi, koma izi zidzakhudza kwambiri mphamvu yamagetsi poyambira, yomwe ili yofanana ndi pafupifupi katatu. voteji wamba.Chofunikira pakuyambira kofewa kwa gridi yamagetsi ndi nthawi 2-3 zapano, ndiye kuti, 560-840A.Komabe, mphamvu yoyambira yofewa pamagetsi ndi pafupifupi 10%, zomwe sizingakhale ndi vuto lalikulu.
