Umenzi weJenereyitha woKhuselo olungaphandle kwenyathelo

I-generator stator yokukhusela impazamo yomhlaba kwi-generator stator yesigaba esinye sokukhusela impazamo yomhlaba, izihlandlo ezithathu ngenye i-voltage ye-zero yolandelelwano olusisiseko kunye nombane we-harmonic wamacandelo amabini, umgca wokuqala we-harmonic zero ulandelelwano lombane wokukhusela umsila ukuya kuma-95% kwindawo ye-stator ejikelezayo enye- impazamo yesigaba sokumisa, ipateni yamandla ebonakalisiweyo kumgaqo wombane wolandelelwano lweziro, ngexesha t1 (3 s) dwelisa intshukumo yemagnethi kwisisombululo;I-voltage yesithathu ye-harmonic ikhusela i-stator ejikelezayo yenqanaba elinye lokumisa impazamo ukusuka emsileni ukuya kwi-30% yesiphelo somatshini, oqulunqwe yindawo engathathi hlangothi yejenereyitha kunye nomgaqo we-harmonic yesithathu yokuphela komatshini, kwaye isebenza umqondiso ngexesha T2 (5s).Zombini zenza i-100% yokhuseleko lwe-stator grounding.Ukhuseleko luxhotyiswe nge-PT wire break lock.

Ukujika kweStator ukujika ukhuseleko lwejenereyitha

Ukhuseleko lubandakanya amandla ombane olandelelwano lwe-longitudinal zero kunye nekhrayitheriya yolandelelwano olubi loluhlu lwempazamo.Umlinganiselo we-PT wokuqhawula uxhulumaniso lusekwe njengokhuseleko oluphambili lwe-inter-turn, i-inter-phase short circuit kunye ne-stator winding opening welding ngaphakathi kwe-generator.Icandelo lesiphoso elibi liqonda ikhrayitheriya yolandelelwano lwe-zero yolandelelwano lwe-longitudinal iqonda i-longitudinal ye-3U0 ephumayo yi-3PT evulekileyo yonxantathu ejikelezayo eqhagamshelwe ngokuthe ngqo kwijeneretha engathathi hlangothi kodwa engasekelwanga ngokubhaqa amandla olandelelwano olubi lwejeneretha.Isenzo sokukhusela siyayeka konke konke.

Umenzi wejenereyitha ukhuseleko lwangaphandle

Ukhuseleko lusebenzisa izinto ezintathu zokuthintela, ngotshintsho lwe-impedance trajectory ukubona inani le-slip pole kunye nokumisela indawo yeziko le-oscillation.Kwimeko yesiphambeko sesiphaluka esifutshane, i-oscillation yenkqubo, ikhefu lesiphaluka se-voltage, njl., ukukhuselwa kwi-misoperation.Gada intshukumo jikelele kumqondiso;Xa iziko le-oscillation lingaphakathi kwejenereyitha kunye neqela le-transformer, icandelo lokukhusela ndiqala ukuthumela umyalelo wokuhamba nge-T1 (0.5s), kwaye isenzo kukucima intsimi yamagnetic.Xa isikhungo se-oscillation singaphandle kwesethi ye-generator-transformer, icandelo lokukhusela II liqaliswa ukubonakalisa nge-T2 (2S).Ukhuseleko luxhotyiswe ngesixhobo sokutshixa ngoku ukuqinisekisa ukuba i-current ayidluli kwi-rated out-of-step breaking current of the circuit breaker xa i-breaker circuit ivaliwe.

Ukhuseleko olusezantsi oluqokelelweyo

Uqokelelo oluphantsi lwenkqubo yokusabela yokhuselo lokuphindaphinda ukucutha isiphumo esongezelekayo sempembelelo yeinjini yomphunga, ukhuseleko lubandakanya ireyiji yefrikhwensi ebuthathaka kunye nekhawuntara, ukutshixa abafowunelwa abancedisayo (oko kukuthi, ijenereyitha ephantsi yokuphuma ngexesha lokhuseleko oluqokelelweyo nayo. yeka ukubaleka), i-frequency cumulative system ingaphantsi kune-47.5 Hz ixesha lokumisela i-frequency, xa ixabiso elimiselweyo kwixesha elipheleleyo ukuya kwi-3000 imizuzwana, i-Signal iya kuthunyelwa emva kokulibaziseka kwe-30 imizuzwana.Isixhobo sinokujongwa ngexesha langempela ngexesha lokusebenza: ixabiso eliqhubekayo, i-frequency F kunye nomboniso wexesha eliqokelelweyo.Ukukhuselwa okungafaniyo kwejenereyitha kunye neqela le-transformer, ukukhuselwa okungafaniyo kwe-transformer kunye nokhuseleko oluphezulu lokwahlukana lukhuselo oluphambili lwe-interphase impazamo yesiphaluka esifutshane samacandelo akhuselweyo, usebenzisa umgaqo wokuqhawula umlinganiselo.Iphutha elingaphandle kwendawo lingakwazi ukuphepha ngokunyanisekileyo umbane ongenakulinganiswa owenziwe ngokungahambelani kweempawu ze-CT zecala ngalinye, kwaye ukukhuselwa kwephutha kwi-zone kunokusebenza ngovelwano.Ukuze ugweme i-misoperation yokukhusela phantsi kwe-transformer inrush yangoku, ukhuseleko luthatha ukutshixa okwesibini kwe-harmonic.Ukukhuselwa kuxhotyiswe ngomsebenzi wokuthintela ukwahlukana kokuhamba kwesantya ngaphandle kwe-wave wave ye-harmonic yesibini, kwaye iphoso inokususwa ngokukhawuleza xa i-different current ifikelela kwixabiso lokumisela.Ukhuseleko lunomsebenzi wokuvala umgca we-CT (ongasetyenziswanga ngokwenene).Ucalucalulo lokuqhawula umgca we-CT luyafana nokukhusela umahluko we-generator.

I-Guangxi Dingbo Power Equipment Manufacturing Co., Ltd. esekwe ngo-2006, ngumvelisi wejenereyitha ye-diesel e-China, edibanisa ukuyila, ukubonelela, ukuthunyelwa kunye nokugcinwa kweseti yejeneretha ye-diesel.Imveliso igubungela iCummins, iPerkins, iVolvo, iYuchai, iShangchai, Dutz , Ricardo, MTU, Weichai njl kunye noluhlu lwamandla 20kw-3000kw, kwaye babe ngumzi-mveliso wabo we-OEM kunye neziko lobuchwepheshe.
