Perkins Generator EMC Design Criteria

Electromagnetic compatibility design criteria ya Perkins jenereta yogwiritsa ntchito data center.

(1) Gwiritsani ntchito mokwanira ndikusewera kwathunthu pamagetsi amagetsi amagetsi omwe amagwiritsidwa ntchito.Kuphatikizirapo: ① kusankha zida zamagetsi zomwe zimalolera ma sign akulu;② Sankhani zida zamagetsi ndi liwiro loyenera;③ Chepetsani kulowererapo kwa gawo lolowera (makamaka gawo lolowera kutali) momwe mungathere;④ Chepetsani kusokoneza kotulutsa moyenera.

(2) Mapangidwe amagetsi amagetsi a Perkins dizilo jenereta .Kuphatikizirapo: ① sankhani gawo lamphamvu lokhala ndi mphamvu yolumikizira pang'ono kumbali yoyambira ndi yachiwiri ndi mphamvu yayikulu yolumikizira pansi kumbali yoyambira;② Landirani mphamvu zogawidwa momwe mungathere;③ Mitundu yogwiritsira ntchito mphamvu ya AC ya module yamagetsi iyenera kukhala yayikulu mokwanira.

(3) Kusankha njira yoyambira pansi.① Nthawi zambiri, kukhazikitsa mwachindunji kumatengedwa;② Pamene gawo lowongolera likulumikizidwa ndi magetsi ndi zida zamphamvu kwambiri, njira yapansi yoyandama imatengedwa;③ Mphamvu yogawidwa ya nthaka yoyandama iyenera kuyendetsedwa mosamalitsa.

(4) Kukonzekera kwa kugawidwa kwa capacitance ya dongosolo lolamulira.① Yesetsani kuchepetsa kulumikizana pakati pa mbali zoyambira ndi zachiwiri kuti mutseke njira yosokoneza wamba;② Mphete yodziwika bwino ya maginito imakutidwa pamalo olowera padoko, ndiyeno symmetrical high-frequency capacitance to ground imalumikizidwa;③ Sungani waya woyatsira kutali ndi mawaya ena;④ Kuchepetsa kugawidwa kwadongosolo;⑤ Yesani mphamvu yogawidwa ya gawo lililonse mpaka pansi, fufuzani kagawidwe ka kusokoneza wamba, yerekezerani zotsatira za kusokoneza wamba, ndipo pangani njira zamakono zoletsa kusokoneza.

Kodi zizindikiro zazikulu zaumisiri za chizindikiro chachikulu ndi zizindikiro zazing'ono ndi ziti?

Zizindikiro zazikulu zaukadaulo zamakina osangalatsa ndi:

(1) Main luso lolozera wa makhalidwe lalikulu chizindikiro: ① kwa ochiritsira poyankha dongosolo malemeredwe, ndi milozera luso pamwamba voteji angapo ndi chisangalalo voteji poyankha chiŵerengero;② Pachisangalalo chokhala ndi kuyankha kwakukulu koyambirira, ma index aukadaulo ndi ma voltage apamwamba angapo komanso nthawi yoyankhira voteji.

(2) Zolozera zazikulu zaukadaulo zamawonekedwe ang'onoang'ono azizindikiro ndi: nthawi yowuka, nthawi yosintha, nthawi yopitilira muyeso ndi nthawi ya oscillation.Ma indexes okhazikika ndi awa: overshoot ≤ 50%, nthawi yosintha ≤ IOS, nthawi za oscillation ≤ 3 nthawi.

Chifukwa chiyani kuyeza kutsekereza kothamanga kwa rotor pamene jenereta yayamba?Kwa ma rotor ena a jenereta, kulakwitsa koyambira kwa jenereta yokhotakhota nthawi zambiri kumakhudzana ndi mphamvu yapakati pomwe rotor imazungulira, koma cholakwika chamtunduwu sichingawonekere pakuyesa kotseka.Chifukwa chake, jenereta ikakwera kuchokera pa liwiro la zero kupita ku liwiro lovotera, kuyeza kutsekeka kwa mafunde a rotor pa siteji iyi kumatha kuweruza ngati pali cholakwika chotere pakuyenda kwa rotor, kuti tipeze cholakwikacho ndikuwonetsetsa kuti palibe ngozi yobisika. ntchito yachibadwa ya mafunde a rotor.

Semiconductor excitation regulator

Mu dongosolo lachisangalalo la semiconductor, gawo lamphamvu lachisangalalo ndi semiconductor rectifier ndi magetsi ake a AC, ndipo chowongolera chosangalatsa chimapangidwa ndi zida za semiconductor, zida zolimba ndi mabwalo apakompyuta.Woyang'anira woyambirira amangowonetsa kupotoka kwamagetsi a jenereta ndikuwongolera voteji.Nthawi zambiri amatchedwa voltage regulator (voltage regulator mwachidule).Wowongolera wapano amatha kuwonetsa momveka bwino ma siginecha osiyanasiyana ophatikizirapo ma siginecha opatuka pamagetsi kuti athe kuwongolera chisangalalo, chifukwa chake amatchedwa excitation regulator.Mwachiwonekere, chowongolera chosangalatsa chimaphatikizapo ntchito yamagetsi owongolera.
