Perkins Generator EMC Design Ma'auni

Ma'auni na ƙirar dacewa da lantarki na janareta na Perkins don amfanin cibiyar bayanai.

(1) Yi cikakken amfani da ba da cikakken wasa ga daidaituwar lantarki na abubuwan lantarki da aka yi amfani da su.Ciki har da: ① zabar kayan aikin lantarki tare da babban juriyar sigina;② Zaɓi kayan aikin lantarki tare da saurin da ya dace;③ Rage tasirin shigarwar da'irar shigarwa (musamman da'irar shigarwa mai nisa) gwargwadon yiwuwa;④ Rage abin da ake fitarwa daidai.

(2) Tsarin tsarin samar da wutar lantarki na Perkins dizal janareta .Ciki har da: ① zaži ma'aunin wutar lantarki tare da ƙananan ƙarfin haɗin gwiwa a gefe na farko da na biyu da kuma babban ƙarfin haɗin gwiwa zuwa ƙasa a gefen farko;② Karɓar tsarin wutar lantarki da aka rarraba gwargwadon yiwuwa;③ Matsakaicin aiki na wutar lantarki na AC na tsarin wutar lantarki dole ne ya zama babba.

(3) Zaɓin yanayin ƙasa.① Gabaɗaya, ana ɗaukar ƙasa kai tsaye;② Lokacin da aka haɗa sashin sarrafawa ta hanyar lantarki tare da kayan aiki mai ƙarfi, ana ɗaukar yanayin ƙasa mai iyo;③ Dole ne a sarrafa ƙarfin ƙarfin da aka rarraba na tsarin ƙasa mai iyo.

(4) Gudanar da ikon rarraba tsarin sarrafawa.① Yi ƙoƙarin rage ƙarfin haɗin kai tsakanin bangarorin farko da na biyu don toshe hanyar tsangwama na gama gari;② Ana lulluɓe zoben maganadisu na yau da kullun a wurin shigar da tashar jiragen ruwa, sannan an haɗa ƙarfin mitoci mai misaltuwa zuwa ƙasa;③ Ka kiyaye waya ta ƙasa daga sauran wayoyi na sigina;④ Rage karfin da aka rarraba na tsarin;⑤ Gwada ƙarfin da aka rarraba na kowane bangare zuwa ƙasa, bincika rarraba kwararar tsangwama na yanayin gama gari, ƙididdige tasirin tsangwama na gama gari, da tsara matakan fasaha don murkushe tsangwama.

Menene manyan alamun fasaha na manyan sigina da ƙananan sigina?

Manyan fihirisar fasaha na tsarin tashin hankali sun haɗa da:

(1) Babban firikwensin fasaha na manyan siginar sigina: ① don tsarin haɓakawa na al'ada na al'ada, ƙididdigar fasaha sune manyan ƙarfin ƙarfin lantarki da yawa da ƙimar amsawar ƙarfin lantarki;② Don tsarin haɓakawa tare da babban amsawar farko, ƙididdiga na fasaha sune babban ƙarfin lantarki da yawa da lokacin amsawar ƙarfin lantarki.

(2) Babban ma'auni na fasaha na ƙananan halayen sigina sune: lokacin tashi, lokacin daidaitawa, overshoot da lokutan oscillation.Matsakaicin ma'auni sune: overshoot ≤ 50%, lokacin daidaitawa ≤ IOS, lokutan oscillation ≤ sau 3.

Me yasa ake auna rufin saurin rotor lokacin da aka fara janareta?Ga wasu rotors na janareta, kuskuren ƙasa na jujjuyawar injin janareta galibi yana da alaƙa da ƙarfin centrifugal lokacin da rotor ke juyawa, amma irin wannan kuskuren ba za a iya nunawa a gwajin da ke ƙarƙashin rufewa ba.Don haka, lokacin da janareta ya tashi daga saurin sifili zuwa saurin da aka ƙididdige shi, auna insulation na rotor winding a wannan matakin zai iya yin hukunci ko akwai irin wannan laifin a cikin injin rotor, ta yadda za a gano kuskuren daidai da tabbatar da cewa babu wani ɓoyayyiyar haɗari a ciki. na al'ada aiki na rotor winding.

Semiconductor excitation regulator

A cikin tsarin motsa jiki na semiconductor, rukunin wutar lantarki shine mai gyara semiconductor da samar da wutar lantarki ta AC, kuma mai sarrafa kuzarin ya ƙunshi abubuwan semiconductor, ingantattun abubuwan haɗin gwiwa da na'urorin lantarki.Mai daidaitawa na farko kawai ya nuna karkatar da wutar lantarki ta janareta kuma ya aiwatar da gyaran wutar lantarki.Yawancin lokaci ana kiransa mai sarrafa wutar lantarki (mai sarrafa wutar lantarki a takaice).Mai sarrafa na yanzu na iya nuna cikakken siginar sarrafawa iri-iri gami da siginar karkatar da wutar lantarki don ƙa'idar tashin hankali, don haka ana kiranta mai sarrafa tashin hankali.Babu shakka, mai sarrafa motsa jiki ya haɗa da aikin mai sarrafa wutar lantarki.
