I-Symmetric Overload Protection For Genset

Isivikelo sokuqongelela imvamisa ephansi

Ukuvikela okunqwabelanayo kwefrikhwensi ephansi kubonisa umthelela okhulayo wokunciphisa imvamisa yesistimu ku-turbine.Isivikelo sakhiwe ngokudluliswa kwefrikhwensi ebucayi kanye nekhawunta, ikhiywe ngokuxhumana okuyisizayo kwe-outlet breaker (okungukuthi, lapho ijeneretha ima ukusebenza, ukuvikela okunqwabelanayo kwefrikhwensi ephansi nakho kuyayeka ukusebenza).Uma imvamisa yesistimu eqoqwayo iphansi kunevelu yokusetha imvamisa engu-47.5Hz, lapho isikhathi esinqwabelanayo sifinyelela inani lokusetha lamasekhondi angu-3000, isenzo sizothumela isignali yokulibaziseka yamasekhondi angu-30.Idivayisi ingaqashelwa ngesikhathi sangempela ngesikhathi sokusebenza: inani elingaguquki, imvamisa F nesikhathi esiqoqiwe kuyaboniswa.Ukuvikelwa okuhlukile kwe-generator transformer, ukuvikelwa okuhlukile kwe-transformer kanye nokuvikelwa okuhlukile kwe-voltage ephezulu ye-transformer kuyisivikelo esiyinhloko ngokumelene nephutha lesifunda esifushane se-interphase yezingxenye ezivikelwe.Esimeni sephutha elingaphandle kwendawo, ukungalingani kwamanje okubangelwa izici ze-CT ezingaguquki zohlangothi ngalunye kungagwenywa ngendlela enokwethenjelwa, futhi ukuvikelwa kwamaphutha endaweni kunesenzo esibucayi.Ukuze ugweme ukuphathwa kabi kokuvikela ngaphansi kwe-transformer inrush current, ukuvikela kusebenzisa ukukhiya kwe-harmonic kwesibili.Isivikelo sinomsebenzi wokunqamula ukuhlukana kwamandla ngaphandle kokukhiya i-harmonic yesibili.Lapho umehluko wamanje ufinyelela inani elimisiwe, iphutha lisuswa ngokushesha.Isivikelo sinomsebenzi wokukhiya umugqa we-CT (awusetshenziswanga ngempela).Ukucwaswa kwe-CT line break kuyafana nokuvikelwa komehluko we-generator.

Isivikelo sokugcwala kwesekethe ejabulisayo

Ukuvikela ukugcwala kwe-loop evusa amadlingozi kusetshenziselwa ukuvikela okuvusa amadlingozi kwe-rotor okudlula kwamanje noma ukuvikela ukulayisha ngokweqile, okuhlukaniswe izigaba ezintathu, ezihlanganisa isikhathi esinqunyiwe nesikhathi esiphambene.

Isenzo samanje sengxenye yesikhathi esimisiwe sisethwa ngokuya ngesimo sokuthi singabuya ngokuthembekile ngaphansi kwamandla amanje alinganiselwe okusebenza okuvamile.Isebenza esignali futhi inciphisa ukuvuthwa kwamanje ngemva komkhawulo wesikhathi T1 (5s) (umphumela wokunciphisa ukuvuthwa kwamanje awusizi);Isici sesenzo somkhawulo wesikhathi esiphambene sinqunywa ngokwamandla okulayisha ngokweqile ama-winding ashukumisayo e-generator, futhi isenzo sokuvikela ukucisha isitimela.Umkhawulo wesikhathi sokubala omkhulu amasekhondi ayi-10.

Isivikelo sendawo ye-rotor ye-generator

Iphuzu elilodwa lokuvikela isisekelo se-rotor ye-generator lisetshenziselwa ukukhombisa iphutha lephoyinti elilodwa le-generator rotor circuit.Ukuvikelwa kusebenzisa isimiso sokushintshwa kwe-ping-pong.I-voltage eqondile nengalungile yesekethe ye-rotor eya phansi isampula ngokulandelana, futhi ukumelana ne-rotor grounding kanye nesimo sokumisa phansi kubalwa ngesikhathi sangempela ngokuxazulula izilinganiso ezimbili ezihlukene zesekethe yesisekelo.Ngemva kokulibaziseka kwamasekhondi angu-2, unogada usebenzisa isignali.

Ukuvikelwa kokulayisha ngokweqile kwe-Symmetric ijeneretha

Idivayisi yokuvikela iqukethe umkhawulo wesikhathi omisiwe kanye nomkhawulo wesikhathi ophambene.Ingxenye yesikhathi esimisiwe amasekhondi angu-5 ngemva kokusetshenziswa kwesignali.Isici sesenzo sesikhathi esiphambene sinqunywa ngokwamandla ejeneretha ukumelana nomthwalo wamanje, futhi isenzo ukuxazulula inkinga.Idivayisi yokuvikela ingabonisa inqubo yokugcina ukushisa ye-generator stator.

Isivikelo sokulayishwa ngokweqile kwe-generator

Idivayisi yokuvikela iqukethe umkhawulo wesikhathi omisiwe kanye nomkhawulo wesikhathi ophambene.Isikhathi esinqunyiwe sesenzo samanje sisethwa ngokuya ngenani lamanje lokulandelana okungalungile ijeneretha elivumela isikhathi eside kanye nenani lamanje ukuze kugwenywe ukungalingani kwesihlungi samanje sokulandelana okungalungile ngaphansi komthwalo omkhulu, futhi sisetshenziswa kusignali ngemva kwe-3- umkhawulo wesikhathi sesibili.Isici sesenzo sesikhathi esiphambene sinqunywa ngokuya nekhono lejeneretha ukumelana namanje okulandelanayo okungalungile, futhi isenzo ukuxazulula ukukhishwa kazibuthe.Idivayisi yokuzivikela ingabonisa inqubo yokugcina ukushisa ye-rotor 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, Shanghai, I-Deutz, i-Ricardo, i-MTU, i-Weichai njll. enebanga lamandla angu-20kw-3000kw, futhi babe isikhungo sabo semboni ye-OEM nobuchwepheshe.
