I-Perkins Generator EMC Design Criteria

I-electromagnetic compatibility design criteria ye-Perkins generator yokusetshenziswa kwesikhungo sedatha.

(1) Sebenzisa ngokugcwele futhi unikeze ukudlala okugcwele ekusebenzisaneni kukazibuthe kwezingxenye ze-elekthronikhi ezisetshenzisiwe.Kubandakanya: ① ​​ukukhetha izingxenye ze-elekthronikhi ezinokubekezelela isignali enkulu;② Khetha izingxenye zikagesi ezinejubane elifanele;③ Yehlisa i-impedance yokokufaka kwesekethe yokufaka (ikakhulukazi isekethe yokufaka eyirimothi) ngangokunokwenzeka;④ Nciphisa okukhiphayo ngendlela efanele.

(2) Idizayini yesistimu yokuphakelwa kwamandla kagesi I-Perkins generator diesel .Kubandakanya: ① ​​khetha imojula yamandla enekhono elincane lokuhlanganisa ohlangothini oluyinhloko nohlangothi lwesibili namandla amakhulu okuhlanganisa phansi ohlangothini oluyinhloko;② Yamukela isakhiwo samandla asabalalisiwe ngangokunokwenzeka;③ Ibanga lokusebenza le-voltage ye-AC yemojuli yamandla kufanele libe likhulu ngokwanele.

(3) Ukukhethwa kwemodi yokubeka phansi.① Ngokuvamile, ukusekela okuqondile kuyamukelwa;② Uma ingxenye yokulawula ixhunywe ngogesi nemishini ye-high-voltage, imodi yaphansi entantayo iyamukelwa;③ Amandla asabalalisiwe wesistimu yaphansi entantayo kufanele ilawulwe ngokuqinile.

(4) Ukucubungula amandla asabalalisiwe wesistimu yokulawula.① Zama ukunciphisa amandla okuhlanganisa phakathi kwezinhlangothi eziyinhloko nesesibili ukuze uvimbe indlela yokuphazamiseka kwemodi evamile;② Indandatho kazibuthe yemodi evamile imbozwa endaweni yokufaka yembobo, bese kuxhunywa i-symmetrical high-frequency capacitance emhlabathini;③ Gcina intambo yaphansi ikude kwezinye izintambo zesignali;④ Yehlisa amandla asabalalisiwe wesistimu;⑤ Hlola amandla asabalalisiwe engxenye ngayinye phansi, hlaziya ukugeleza kokusatshalaliswa kokuphazamiseka kwemodi evamile, linganisa umthelela wokuphazamiseka kwemodi evamile, futhi wenze izinyathelo zobuchwepheshe zokucindezela ukuphazamiseka.

Yiziphi izinkomba zobuchwepheshe eziyinhloko zesignali enkulu nezici zesignali ezincane?

Izinkomba eziyinhloko zobuchwepheshe zesistimu yokuvusa zihlanganisa:

(1) Main izinkomba lobuchwepheshe izici ezinkulu isignali: ① for ezivamile impendulo uhlelo excitation, izinkomba lobuchwepheshe kukhona voltage phezulu multiple kanye excitation voltage impendulo ratio;② Ohlelweni lwe-excitation olunempendulo ephezulu yokuqala, izinkomba zobuchwepheshe ziyi-voltage ephezulu ephindaphindekayo kanye nesikhathi sokuphendula samandla kagesi.

(2) Izinkomba eziyinhloko zobuchwepheshe zezici zesignali ezincane yilezi: isikhathi sokukhuphuka, isikhathi sokulungiswa, izikhathi zokudubuleka ngokweqile kanye nezikhathi ze-oscillation.Izinkomba ezijwayelekile ziyi: overshoot ≤ 50%, isikhathi sokulungiswa ≤ IOS, izikhathi ze-oscillation ≤ izikhathi ezingu-3.

Kungani ulinganisa i-rotor speed-up insulation lapho i-generator iqalisiwe?Kwamanye ama-rotor akhiqiza i-generator, iphutha lokumisa i-generator rotor winding ngokuvamile lihlobene namandla aphakathi nendawo lapho i-rotor izungeza, kodwa lolu hlobo lwephutha alukwazi ukuboniswa ekuhlolweni ngaphansi kokuvala shaqa.Ngakho-ke, lapho i-generator ikhuphuka isuka ku-zero isivinini iye kwisivinini esilinganisiwe, ukulinganisa ukufakwa kwe-rotor mawinding kulesi sigaba kungahlulela ukuthi ngabe kukhona iphutha elinjalo ekujikeni kwe-rotor, ukuze uthole ngokunembile iphutha futhi uqinisekise ukuthi ayikho ingozi efihliwe. ukusebenza okuvamile kwe-rotor winding.

Isilawuli sokuthakazelisa se-semiconductor

Kusistimu ye-semiconductor evusa amadlingozi, iyunithi yamandla avusa amadlingozi iyisilungisi se-semiconductor namandla ayo e-AC, futhi isilawuli esivusa amadlingozi sakhiwe izingxenye ze-semiconductor, izingxenye eziqinile namasekhethi kagesi.Isilawuli sokuqala sibonisa kuphela ukuchezuka kwe-voltage ye-generator futhi senza ukulungiswa kwe-voltage.Ngokuvamile kubizwa ngokuthi i-voltage regulator (i-voltage regulator ngamafuphi).Isilawuli samanje singabonisa ngokuphelele amasiginali okulawula ahlukahlukene okuhlanganisa isignali yokuchezuka kagesi yokulawula ukuvusa, ngakho-ke kubizwa nge-excitation regulator.Ngokusobala, i-excitation regulator ihlanganisa umsebenzi we-voltage regulator.
