Isivikelo Esingaphandle Kwesinyathelo Somkhiqizi Wejeneretha

Isivikelo sephutha se-generator stator sokuvikela amaphutha e-generator stator yesigaba esisodwa, kathathu ngogesi othize olandelanayo onguziro kanye nogesi we-harmonic wezingxenye ezimbili, umsila wokuqala we-harmonic ziro olandelanayo wokuvikela umsila ufinyelela ku-95% endaweni ye-stator ejikajikayo eyodwa- iphutha lesigaba, iphethini yamandla ebonisiwe kumgomo kagesi wokulandelana kukaziro, ngesikhathi u-t1 (3 s) ekhipha isenzo sikazibuthe esixazululweni;I-voltage yesithathu ye-harmonic ivikela iphutha le-stator elivunguzayo lesigaba esisodwa ukusuka emsileni ukuya ku-30% wokuphela komshini, elakhiwe iphuzu elingathathi hlangothi le-generator kanye nesimiso se-harmonic yesithathu yokuphela komshini, futhi isebenza isignali ngesikhathi t2 (5s).Kokubili kuhlanganisa ukuvikelwa okungu-100% kwe-stator grounding.Isivikelo sifakwe i-PT wire break lock.

I-Stator Turn ukuvula ukuvikelwa kwejeneretha

Isivikelo sakhiwe ngevolthi yelongitudinal elandelanayo eyiziro kanye nesimiso sokulandelana esingalungile sokuhlukaniswa kwephutha.Isilinganiso sokuvimbela ukunqanyulwa kwe-PT sisethwe njengesivikelo esiyinhloko se-inter-turn, inter-phase short circuit kanye ne-stator winding opening welding ngaphakathi kwe-generator.Isici sephutha inkomba yendlela yokulandelana eyinegethivu ibona umbandela wevoltheji ye-longitudinal uziro wokulandelana ibona ukuphuma kwe-longitudinal 3U0 ngokujika kukanxantathu ovulekile we-3PT exhunywe ngokuqondile ku-generator neutral kodwa engasekelwe ngokuthola amandla alandelanayo angalungile ejeneretha.Isenzo sokuvikela siyama nhlobo.

Umkhiqizi we-generator ukuvikela ngaphandle kwesinyathelo

Isivikelo sisebenzisa izakhi ezintathu ze-impedance, ngoshintsho lwe-impedance trajectory ukuze kutholwe inani le-slip pole nokunquma indawo yesikhungo se-oscillation.Endabeni yephutha lesifunda esifushane, i-oscillation yesistimu, ikhefu lesifunda se-voltage, njll., ukuvikelwa ekusetshenzisweni kabi.Gada isenzo esijwayelekile esignali;Uma isikhungo se-oscillation singaphakathi kweqembu le-generator ne-transformer, isigaba sokuvikela siqala ukuthumela umyalo wokukhubeka nge-T1 (0.5s), futhi isenzo siwukuvala inkambu kazibuthe.Uma isikhungo se-oscillation singaphandle kwesethi ye-generator-transformer, isigaba sokuvikela II siqaliswa ukuze sisayine nge-T2 (2S).Isivikelo sifakwe idivayisi yamanje yokukhiya ukuze kuqinisekiswe ukuthi i-current ayidluli isilinganiso sokuphuma ngaphandle kwesinyathelo samanje se-circuit breaker uma i-circuit breaker ivaliwe.

Ukuvikelwa kokuqongelela imvamisa ephansi

Imvamisa ephansi yesistimu yokusabela evikela imvamisa ephansi yokunciphisa umthelela wokuqongelela womthelela weturbine yesitimu, ukuvikelwa kwakhiwe i-relay ebucayi nekhawunta, ukukhiya oxhumana nabo abasizayo be-outlet circuit breaker (okungukuthi, i-low frequency generator exit runtime generator ukuvikela okunqwabelanayo nakho. yeka ukusebenza), imvamisa yesistimu eqoqiwe ingaphansi kwesikhathi sokusetha esingu-47.5 Hz, lapho amanani asethiwe esikhathi esiphelele ukuya kumasekhondi angu-3000, Isiginali izothunyelwa ngemva kokulibaziseka kwamasekhondi angu-30.Idivayisi ingaqashelwa ngesikhathi sangempela ngesikhathi sokusebenza: inani elingaguquki, imvamisa F kanye nesibonisi sesikhathi esiqoqiwe.Ukuvikelwa okuhlukile kwe-generator kanye neqembu le-transformer, ukuvikelwa okuhlukile kwe-transformer kanye nokuvikelwa okuphezulu kokuhluka kuyisivikelo esiyinhloko sephutha lesifunda esifushane se-interphase yezingxenye ezivikelwe, kusetshenziswa isimiso sokubhuleka isilinganiso.Iphutha langaphandle kwendawo lingagwema ngokuthembekile imanje elingalinganiseli elikhiqizwe ukungahambisani kwezimpawu ze-CT zohlangothi ngalunye, futhi ukuvikelwa kwamaphutha okungaphakathi kwendawo kungenza ngokuzwela.Ukuze ugweme ukuphathwa kabi kokuvikela ngaphansi kwe-transformer inrush current, ukuvikela kusebenzisa ukukhiya kwe-harmonic kwesibili.Ukuvikelwa kufakwe umsebenzi wokuvimbela ukugeleza kokuhluka ngaphandle kwegagasi lesibili le-harmonic, futhi iphutha lingasuswa ngokushesha lapho umehluko wamanje ufinyelela inani lokusetha.Isivikelo sinomsebenzi wokukhiya umugqa we-CT (awusetshenziswanga ngempela).Ukucwaswa kwe-CT line break kuyafana nokuvikelwa komehluko we-generator.

I-Guangxi Dingbo Power Equipment Manufacturing Co., Ltd. eyasungulwa ngo-2006, ingumkhiqizi wejeneretha kadizili eChina, ehlanganisa ukuklama, ukuhlinzeka, ukugunyazwa nokugcinwa kwesethi yejeneretha yedizili.Umkhiqizo uhlanganisa iCummins, iPerkins, iVolvo, iYuchai, iShangchai, Duutz , Ricardo, MTU, Weichai njll. enebanga lamandla angu-20kw-3000kw, futhi babe yisikhungo sabo semboni ye-OEM nobuchwepheshe.
