Mozungulira mozungulira

Pali mitundu yambiri yamakina amagetsi ozungulira.Malinga ndi ntchito zawo, iwo anawagawa jenereta ndi injini.Kutengera mtundu wamagetsi, amagawidwa kukhala ma mota a DC ndi ma AC motors.Malingana ndi mapangidwe awo, amagawidwa kukhala ma synchronous motors ndi asynchronous motors.Malinga ndi kuchuluka kwa magawo, ma asynchronous motors amatha kugawidwa mu magawo atatu asynchronous motors ndi single phase asynchronous motors;molingana ndi mawonekedwe awo osiyanasiyana a rotor, amagawidwa kukhala khola ndi mitundu yozungulira yamabala.Mwa iwo, khola la magawo atatu asynchronous motors ndi osavuta kupanga komanso kupanga.Kusavuta, mtengo wotsika, ntchito yodalirika, yomwe imagwiritsidwa ntchito kwambiri pamagalimoto osiyanasiyana, chofunikira kwambiri.Kutetezedwa kwa mphezi kwa makina ozungulira magetsi (jenereta, kusintha makamera, ma motors akuluakulu, ndi zina zotero) ndizovuta kwambiri kuposa za transformers, ndipo ngozi ya mphezi nthawi zambiri imakhala yochuluka kuposa ya transformers.Izi ndichifukwa choti makina amagetsi ozungulira amakhala ndi mikhalidwe yosiyana ndi thiransifoma potengera kapangidwe kanyumba, magwiridwe antchito komanso kulumikizana.
(1) Pakati pa zida zamagetsi zomwe zili mulingo womwewo wa voteji, mphamvu yolimbana ndi voteji yamakina amagetsi ozungulira ndiyotsika kwambiri.
Chifukwa chake ndi: ①Motor ili ndi rotor yothamanga kwambiri, kotero imatha kugwiritsa ntchito sing'anga yolimba, ndipo singathe kugwiritsa ntchito madzi olimba (mafuta osinthika) ophatikizika apakati ngati thiransifoma: panthawi yopanga, sing'anga yolimba imawonongeka mosavuta. , ndi kutchinjiriza ndi Voids kapena mipata sachedwa kuchitika, kotero kukhetsa pang'ono ndi sachedwa kuchitika pa ntchito, kumabweretsa kuwonongeka kutchinjiriza;②Njira zogwirira ntchito zotsekemera zamagalimoto ndizowopsa kwambiri, zomwe zimatengera kutentha, kugwedezeka kwamakina, chinyezi mumlengalenga, kuipitsidwa, kupsinjika kwamagetsi, ndi zina zambiri, Kuthamanga kwa ukalamba kumathamanga;③Munda wamagetsi wamagetsi opangira magetsi ndi ofanana, ndipo mphamvu yake imakhala pafupi ndi 1. Mphamvu yamagetsi pansi pa overvoltage ndiyo ulalo wofooka kwambiri.Chifukwa chake, ma voliyumu ovoteledwa ndi mulingo wotsekemera wa mota sangakhale wokwera kwambiri.
(2) Mphamvu yotsalira ya chomangira mphezi yomwe imagwiritsidwa ntchito kuteteza mota yozungulira ili pafupi kwambiri ndi mphamvu yolimbana ndi mphamvu yamotoyo, ndipo malirewo ndi ochepa.
Mwachitsanzo, mphamvu ya fakitale kupirira voteji mayeso mtengo wa jenereta ndi 25% mpaka 30% apamwamba kuposa 3kA yotsalira voteji mtengo wa zinc okusayidi arrester, ndi m'mphepete mwa maginito kuwombeza arrester ndi yaing'ono, ndi kutchinjiriza malire adzakhala kutsika pamene jenereta ikuyenda.Choncho, sikokwanira kuti galimotoyo itetezedwe ndi womanga mphezi.Iyenera kutetezedwa ndi kuphatikiza kwa ma capacitor, ma reactors, ndi zigawo za chingwe.
(3) Kutsekereza kwapakati-kutembenuza kumafuna kuti kutsetsereka kwa mafunde olowera kumakhala kochepa.
Chifukwa capacitance yapakati-kutembenukira mphamvu ya mafunde agalimoto ndi yaying'ono komanso yosalekeza, mafunde opitilira muyeso amatha kufalikira mozungulira kokondakita akalowa m'mapiritsi agalimoto, ndipo kutalika kwa kutembenuka kulikonse kumakhala kokulirapo kuposa kupiringa kwa thiransifoma. , kuchita mozungulira kuwiri koyandikana Kuchuluka kwamagetsi kumayenderana ndi kutsetsereka kwa mafunde olowera.Kuti muteteze kutsekereza kwapakati pa injini, kutsetsereka kwa mafunde olowera kuyenera kukhala kochepa.
Mwachidule, zofunikira zotetezera mphezi zamakina ozungulira magetsi ndizokwera komanso zovuta.Ndikofunikira kuganizira mozama zofunikira zachitetezo cha kutsekereza kwakukulu, kutsekereza kwapakati-kutembenuka ndi kutsekereza kopanda ndale kwa mafunde.
