Mota ine simba guru
Kazhinji zvinotendwa kuti mota ine voltage ye3KV ~ 10KV inonzimota ine simba guru.Mota dze6300V ne10000V ndidzo dzinoshandiswa zvakanyanya. Simba remota rinoenderana nemagetsi nemagetsi, saka simba remota ine magetsi mashoma rinowedzera kusvika pamwero wakati (se300KW/380V), magetsi akayerwa achava makuru kwazvo, kurasikirwa kwemutsetse kuchave kwakaenzana nekuwedzera kwemagetsi (I^2*r), nzvimbo yewaya inodiwa kuti ive yakakura kwazvo, saka kugona kwekutakura kwetambo kwakaganhurirwa, uye mutengo wakanyanya kukwira. Panguva ino, zvinodikanwa kuwedzera magetsi akayerwa kuti uwane simba rakawanda rekubudisa.
Mota ine simba shoma
Mota ine voltage yakaderera inoreva AC voltage iri pasi pe1000V mota, inowanzo kureva mota yeAC 380V, 440V kana 660V nedzimwe nhanho dzemota dzisina kuenderanachaizvoizvo hadzishandiswi zvakanyanya. Mota ine voltage shoma yakakamurwa kuita mota dzisina AC uye mota yeDC mhando mbiri.
Zvakanakira nekuipira kwemamota ane simba guru kana tichienzanisa nemamota ane simba shoma
(1) Zvakanakira
(1) inogona kugadzirwa nesimba guru, kusvika kuzviuru kana kunyange makumi ezviuru zve kilowatts. Izvi zvinodaro nekuti, musimba rimwe chete rekuburitsa, simba remagetsi e ...
② Kune mota dzine simba guru, mota dzine simba guru dzinoshandiswa mumidziyo yemagetsi nemidziyo yekuparadzira magetsi kupfuura mari inoshandiswa mumota dzine simba shoma, uye kurasikirwa kwemutsetse kudiki, kunogona kuchengetedza simba rakati wandei. Kunyanya, mota dzine simba guru re10kV, unogona kushandisa zvakananga network power supply (magetsi emagetsi eChina anopiwa kune vashandisi kazhinji 10kV), kuitira kuti mari inoshandiswa mumidziyo yemagetsi (kunyanya transformers) ive shoma, kushandiswa kwayo kuri nyore, uye mwero wekukundikana uchava mudiki.
(2) Zvakashata
① Mutengo wekumonera wakakwira zvakanyanya (zvikurukuru unokonzerwa nekumonera), uye mutengo wezvinhu zvine chekuita nekumonera uchava wakakwirawo.
(ii) Maitiro ekugadzirisa insulation akaoma, uye mari yevashandi yakakwira.
③ Zvinodiwa pakushandisa nharaunda zvakanyanya kuoma kupfuura zvemamota ane voltage shoma.
Kuenzanisa musiyano uripo pakati pemota ine voltage shoma nemota ine voltage yakakwira
Musiyano mukuru muchimiro
Chekutanga, zvinhu zvekudzivirira macoil zvinoita mutsauko, mota dzine voltage shoma, coil inonyanya kushandisa waya dzakapfava kana dzimwe nzira dziri nyore dzekudzivirira, dzakadai sepepa re composite, high-voltage motor insulation inowanzo shandiswa mu multi-layer structure, senge powdered mica tape, chimiro chacho chakaoma, uye chinodzivisa kumanikidzwa zvakanyanya.
Chechipiri, musiyano uripo pakutonhodza, mota dzine voltage shoma dzinonyanya kushandisa mafeni ecoaxial anofemera zvakananga kuti abvise kupisa, mota dzine voltage yakawanda dzine radiator yakazvimirira, kazhinji mhando mbiri dzemafeni, seti yefeni yekutenderera kwemukati, seti yefeni yekutenderera kwekunze, seti mbiri dzemafeni dzinomhanya panguva imwe chete, kuchinjana kwekupisa pa radiator kuchaburitswa kunze kwekupisa kwemota.
Chechitatu, chimiro chebearing chakasiyana, mota dzine voltage shoma dzinowanzova nemabearing asati asvika uye apera, nepo mota dzine voltage yepamusoro, nekuda kwemutoro unorema, kazhinji dzine mabearing maviri pamucheto weaxial, uye huwandu hwemabearing pamucheto weaxial hunotsanangurwa zvichienderana nemamiriro emutoro, uye kunyanya mota hombe dzinoshandisa mabearing anotsvedza.
Kuenzanisa mashandiro emota nemutengo wayo
1. Kana voltage yakakwira, simba remota rinokurawo.
2, kana voltage yakakwira, mutengo wekuisa wakakwira; kunyangwe voltage ichiwedzera, magetsi anova madiki, waya netambo zvinogona kusarudzwa zvidiki, asi kudiwa kwema "high-voltage circuit breakers", ma "transformers", ma "switchgear" nezvimwe zvinodhura zvichiri kuwedzera mukudyara kwekutanga mu "hombe", saka mabhizinesi madiki ari mukuvaka kutsva anoda kushandisa michina ine "low-voltage".
3, kana voltage yakakwira, mari yekushandisa yese yakaderera; diki current inoderedza kurasikirwa kwemagetsi, nekufamba kwenguva yakakodzera, mhedzisiro yekuunganidza yekuchengetedza simba inoshamisa, saka mabhizinesi mazhinji makuru mukushandurwa kwetekinoroji kwemamota ane voltage shoma akachinjwa kuita mota dzine voltage yakawanda.
4, kana voltage yakakwira, nzvimbo yakawanda inotorwa; nekuti kune makabati ekudzora ane voltage yakawanda nevamwe vanogaramo.
5, kana voltage yakakwira, mota iri nyore kutanga, torque yekutanga inowedzera, kutanga, kutonga kuri nyore.
6, kana voltage yakakwira, manejimendi ekugadzirisa akaomarara; saka mabhizinesi madiki anoda kushandisa voltage yakaderera, mabhizinesi makuru anoda kushandisa mota dzine voltage yakawanda.
