Njengamanje, ukushoda kukagesi emhlabeni wonke kuya ngokuya kuba kubi kakhulu. Izinkampani eziningi nabantu ngabanye bakhetha ukuthenga amasethi ejeneretha ukuze kuncishiswe imingcele yokukhiqiza nokuphila okubangelwa ukuntuleka kwamandla. I-AC alternator ingenye yezingxenye ezibalulekile zesethi yonke yejeneretha. Ungakhetha kanjani ama-alternators athembekile, amathiphu alandelayo kufanele aqashelwe:
I. Izici zikagesi:
1. Uhlelo lokuvusa amadlingozi: Kulesi sigaba, isistimu ethokozisayo ye-alternator yekhwalithi ephezulu ye-AC iyazivusa ngokwayo, evamise ukufakwa isilawuli sikagesi esizenzakalelayo (AVR). Amandla okukhipha we-exciter rotor adluliselwa ku-rotor host ngokusebenzisa i-rectifier. Izinga lokulungiswa kwamandla kagesi we-AVR ngokuvamile lingu-≤1%. Phakathi kwazo, i-AVR yekhwalithi ephezulu futhi inemisebenzi eminingi efana nokusebenza okufanayo, ukuvikela imvamisa ephansi, nokulungiswa kwamandla kagesi kwangaphandle.
2. I-Insulation kanye ne-varnishing: Ibanga lokufakwa kwe-insulation lama-alternator ekhwalithi ephezulu ngokuvamile liyisigaba "H", futhi zonke izingxenye zalo ezisongayo zenziwe ngezinto ezithuthukiswe ngokukhethekile futhi zifakwe inqubo ekhethekile. I-alternator isebenza ezindaweni ezinzima ukuze inikeze ukuvikeleka.
3. Ukusebenza kwe-Winding kanye nogesi: I-stator ye-alternator yekhwalithi ephezulu izokwenziwa i-laminated ngamapuleti ensimbi abandayo ane-permeability yamagnetic ephezulu, ama-windings aphindwe kabili, isakhiwo esiqinile kanye nokusebenza okuhle kokushisa.
4. Ukuphazamiseka kocingo: I-THF (njengoba ichazwe yi-BS EN 600 34-1) ingaphansi kuka-2%. I-TIF (njengoba ichazwe yi-NEMA MG1-22) ingaphansi kwama-50
5. Ukuphazamiseka komsakazo: Imishini ye-brushless yekhwalithi ephezulu kanye ne-AVR izoqinisekisa ukuthi kukhona ukuphazamiseka okuncane phakathi nokusakazwa komsakazo. Uma kunesidingo, idivayisi eyengeziwe yokucindezela i-RFI ingafakwa.
II. Izici zemishini:
Izinga lokuvikela: Izinhlobo ezijwayelekile zawo wonke amajeneretha e-AC asemhlabeni yi-IP21, IP22 ne-IP23 (NEMA1). Uma kunesidingo sokuvikela esiphezulu, ungakhetha ukuthuthukisa izinga lokuvikela le-IP23. Uhlobo olujwayelekile lwejeneretha ye-AC yasolwandle yi-IP23, IP44, IP54. Uma udinga ukuthuthukisa izinga lokuvikela, njengokuthi indawo ezungezile ingasolwandle, ungahlomisa ijeneretha ye-AC ngezinye izesekeli, njengezifudumezi zasemkhathini, izihlungi zomoya, njll.
Ukushoda kwamandla emhlabeni kunyuse kakhulu ukuthengiswa kwe-AC alternator/ generator. Izintengo zezinsiza zejeneretha ye-AC ezifana nama-disc coupling nama-rotor akhuphuke kakhulu. Ukunikezwa kuqinile. Uma udinga ugesi, ungathenga amajeneretha e-AC ngokushesha okukhulu. Intengo yamajeneretha e-AC nayo ikhuphuka njalo!
