Perkins Jenareta EMC Dhizaini Criteria

Electromagnetic inoenderana dhizaini dhizaini yePerkins jenareta yekushandisa data data.

(1) Shandisa zvizere uye ipa yakazara kutamba kune electromagnetic kuenderana kwezvinhu zvemagetsi zvinoshandiswa.Kusanganisira: ① kusarudza zvinhu zvemagetsi zvine kushivirira kwechiratidzo chikuru;② Sarudza zvigadzirwa zvemagetsi zvine kumhanya kwakakodzera;③ Deredza iyo impedance yekupinza yedunhu rekuisa (kunyanya iyo iri kure yekuisa reketi) zvakanyanya sezvinobvira;④ Deredza kuburitsa impedance zvakakodzera.

(2) Simba rekupa system dhizaini ye Perkins dizeli jenareta .Kusanganisira: ① sarudza iyo module yemagetsi ine diki coupling capacitance kudivi rekutanga uye yechipiri divi uye yakakura coupling capacitance pasi kudivi rekutanga;② Adopt yakagoverwa simba chimiro zvakanyanya sezvinobvira;③ Kushanda kweiyo AC voltage yemagetsi module inofanira kunge yakakura zvakakwana.

(3) Kusarudzwa kwepasi mode.① Kazhinji, kudzika kwakananga kunogamuchirwa;② Kana chikamu chekutonga chakabatana nemagetsi ne-high-voltage midziyo, iyo inoyangarara pasi modhi inogamuchirwa;③ Iyo yakagovaniswa capacitance yeinoyangarara pasi system inofanira kunyatsodzorwa.

(4) Kugadziriswa kweiyo yakagoverwa capacitance yekutonga system.① Edza kuderedza coupling capacitance pakati pekutanga uye yechipiri mativi kuvharira nzira yeyakajairwa kupindira;② A common mode magineti mhete inovharirwa panzvimbo yekupinza yechiteshi, uye ipapo symmetrical high-frequency capacitance kusvika pasi yakabatana;③ Chengetedza waya yekudzika kure nedzimwe waya dzechiratidzo;④ Deredza kugovaniswa kweiyo system;⑤ Edza kugona kwakagoverwa kwechikamu chimwe nechimwe pasi, ongorora kuyerera kugoverwa kwezvakajairwa modhi kupindira, fungidzira kukanganisa kwezvakajairwa modhi kukanganiswa, uye gadzira matanho ehunyanzvi ekudzvinyirira kupindira.

Ndeapi makuru ehunyanzvi zviratidzo zvechiratidzo chikuru uye diki chiratidzo hunhu?

Huru tekinoroji indexes ye excitation system inosanganisira:

(1) Huru tekinoroji indekisi yeakakura masaini maitiro: ① kune yakajairwa mhinduro yekukurudzira sisitimu, iyo tekinoroji indexes ndeyepamusoro voltage akawanda uye excitation voltage mhinduro reshiyo;② Kune iyo yekunakidzwa sisitimu ine yakakwirira yekutanga mhinduro, iyo tekinoroji indexes ndiyo yepamusoro voltage kuwanda uye excitation voltage mhinduro nguva.

(2) Iyo huru tekinoroji indexes yediki masaini maitiro ndeaya: kusimuka nguva, kugadzirisa nguva, overshoot uye oscillation nguva.Nhamba dzakajairika ndeidzi: overshoot ≤ 50%, nguva yekugadzirisa ≤ IOS, oscillation nguva ≤ 3 nguva.

Sei kuyera rotor speed-up insulation kana jenareta yatangwa?Kune mamwe majenareta ejenareta, kukanganisa kwepasi kwejenareta rotor winding inowanzoenderana necentrifugal simba kana rotor inotenderera, asi rudzi urwu rwekukanganisa harugone kuratidzwa mukuedzwa pasi pekuvhara.Naizvozvo, kana jenareta ichisimuka kubva pa zero kumhanya kusvika kumhanyisa yakayerwa, kuyera kuvharirwa kwe rotor mhepo panguva ino kunogona kutonga kana paine chikanganiso chakadai mukutenderera kwerotor, kuitira kuti uwane chokwadi chikanganiso uye kuve nechokwadi kuti hapana njodzi yakavanzika mukati. iyo yakajairika kushanda kwe rotor winding.

Semiconductor excitation regulator

Mune semiconductor excitation system, iyo yekukurudzira simba unit ndiyo semiconductor rectifier uye yayo AC simba rekupa, uye excitation regulator inoumbwa semiconductor zvikamu, yakasimba zvikamu uye zvemagetsi maseketi.Iyo yekutanga regulator yaingoratidza kutsauka kwejenareta uye kuita kugadzirisa kwemagetsi.Inowanzonzi voltage regulator (voltage regulator kwenguva pfupi).Iyo yazvino regulator inogona kunyatso ratidza zvakasiyana-siyana zvekudzora masiginecha anosanganisira voltage deviation signal yeexcitation regulation, saka inonzi excitation regulator.Zviripachena, iyo excitation regulator inosanganisira basa remagetsi regulator.
