Njengamanje, ukushoda kwamandla emhlabeni wonke kuya ngokuya kuba kubi kakhulu. Izinkampani eziningi kanye nabantu ngabanye bakhetha ukuthenga amasethi ejeneretha ukuze kuncishiswe imikhawulo ekukhiqizweni nasekuphileni okubangelwa ukuntuleka kwamandla. I-AC alternator ingenye yezingxenye ezibalulekile zesethi yejeneretha ephelele. Indlela yokukhetha ama-alternator athembekile, amathiphu alandelayo kudingeka aqashelwe:
I. Izici zikagesi:
1. Uhlelo lokuvusa: Kulesi sigaba, uhlelo lokuvusa lwe-AC alternator esezingeni eliphezulu luyi-self-excitation, evame ukufakwa i-automatic voltage regulator (AVR). Amandla okukhipha e-exciter rotor adluliselwa ku-host rotor nge-rectifier. Izinga lokulungiswa kwe-voltage ye-steady-state ye-AVR ikakhulukazi lingu-≤1%. Phakathi kwazo, i-AVR esezingeni eliphezulu nayo inemisebenzi eminingi efana nokusebenza okuhambisanayo, ukuvikelwa kwemvamisa ephansi, kanye nokulungiswa kwe-voltage yangaphandle.
2. Ukuvikela kanye nokuvanisha: Izinga lokuvikela lama-alternator asezingeni eliphezulu ngokuvamile liyi-class "H", futhi zonke izingxenye zalo ezigoqayo zenziwe ngezinto ezithuthukiswe ngokukhethekile futhi zifakwe inqubo ekhethekile. I-alternator isebenza ezindaweni ezinzima ukuze inikeze isivikelo.
3. Ukusebenza kahle kokugoqa kanye nokusebenza kukagesi: I-stator ye-alternator esezingeni eliphezulu izofakwa amapuleti ensimbi aqoqwe ngokubandayo anokuvuleka okuphezulu kwamagnetic, ama-winding ahlanganiswe kabili, isakhiwo esiqinile kanye nokusebenza kahle kokuvikela.
4. Ukuphazamiseka kocingo: I-THF (njengoba kuchaziwe yi-BS EN 600 34-1) ingaphansi kuka-2%. I-TIF (njengoba ichaziwe yi-NEMA MG1-22) ingaphansi kuka-50
5. Ukuphazamiseka komsakazo: Amadivayisi angenamabhulashi asezingeni eliphezulu kanye ne-AVR kuzoqinisekisa ukuthi akukho ukuphazamiseka okuncane ngesikhathi sokudluliselwa komsakazo. Uma kudingeka, kungafakwa idivayisi eyengeziwe yokucindezela i-RFI.
II. Izici zemishini:
Izinga lokuvikelwa: Izinhlobo ezijwayelekile zazo zonke izinjini ze-AC zomhlaba yi-IP21, IP22 kanye ne-IP23 (NEMA1). Uma kunesidingo sokuvikelwa esiphezulu, ungakhetha ukuthuthukisa izinga lokuvikelwa le-IP23. Uhlobo olujwayelekile lwenjini ye-AC yasolwandle yi-IP23, IP44, IP54. Uma udinga ukuthuthukisa izinga lokuvikelwa, njengokuthi indawo ezungezile iseduze nolwandle, ungahlomisa injini ye-AC ngezinye izesekeli, njengezifudumezi zesikhala, izihlungi zomoya, njll.
Ukuntuleka kukagesi emhlabeni wonke kukhuphule kakhulu ukuthengiswa kwama-alternator/amajeneretha e-AC. Amanani ezesekeli zamajeneretha e-AC njenge-disc couplings nama-rotor akhuphuke kakhulu. Ukunikezwa kukagesi kuncane. Uma udinga ugesi, ungathenga amajeneretha e-AC ngokushesha okukhulu. Intengo yamajeneretha e-AC nayo ikhuphuka njalo!
