UKhuseleko lwe-Symmetric Overload ye-Genset

Ukhuseleko lokuqokelelwa kwamaza aphantsi

Ukhuseleko lokuqokelelwa kwamaza aphantsi lubonisa isiphumo esongezelekayo sokunciphisa amaza enkqubo kwi-injini yomoya.Ukhuseleko luqulunqwe nge-relay frequency kunye ne-counter, itshixiwe ngoqhagamshelwano oluncedisayo lwe-breaker circuit outlet (oko kukuthi, xa i-generator iyeka ukusebenza, ukhuseleko lwe-accumulative low-frequency luyayeka ukusebenza).Xa i-frequency accumulative system iphantsi kunexabiso lokumisela i-frequency ye-47.5Hz, xa ixesha lokuqokelela lifikelela kwixabiso lokumisela imizuzwana ye-3000, isenzo siya kuthumela isignali yokulibaziseka kwemizuzwana ye-30.Isixhobo sinokujongwa ngexesha langempela ngexesha lokusebenza: ixabiso eliqhubekayo, i-frequency F kunye nexesha eliqokelelweyo liboniswa.Ukukhuselwa okungafaniyo kwe-generator transformer, ukukhuselwa okungafaniyo kwe-transformer kunye nokukhusela okungafaniyo kwe-voltage ephezulu ye-voltage lukhuselo oluphambili kwi-interphase impazamo yesiphaluka esifutshane samacandelo akhuselweyo.Kwimeko yephutha elingaphandle kwendawo, ukungalingani kwangoku okubangelwa iimpawu ze-CT ezingahambelaniyo zecala ngalinye kunokuphetshwa ngokuthembekileyo, kwaye ukukhuselwa kwephutha kwi-zone kunesenzo esibucayi.Ukuze ugweme i-misoperation yokukhusela phantsi kwe-transformer inrush yangoku, ukhuseleko luthatha ukutshixa okwesibini kwe-harmonic.Ukukhuselwa kunomsebenzi wokuqhawula umbane ohlukeneyo ngaphandle kokutshixa i-harmonic yesibini.Xa ulwahlulo lwangoku lufikelela kwixabiso elimiselweyo, impazamo isuswa ngoko nangoko.Ukhuseleko lunomsebenzi wokuvala umgca we-CT (ongasetyenziswanga ngokwenene).Ucalucalulo lokuqhawula umgca we-CT luyafana nokukhusela umahluko we-generator.

Ukukhuselwa komthwalo wesekethe yokuvuselela

I-excitation loop overload protection isetyenziselwa ukubuyisela i-rotor excitation edlulayo yangoku okanye ukhuseleko lomthwalo ogqithisiweyo, olwahlulahlulwe lwaba zizigaba ezithathu, ezibandakanya ixesha elimiselweyo kunye nexesha eliguquguqukayo.

Intshukumo yangoku yenxalenye yexesha elimiselweyo imiselwe ngokwemeko yokuba inokubuyela ngokuthembekileyo phantsi komlinganiselo olinganisiweyo wokusebenza okuqhelekileyo.Isebenza kwisignali kwaye inciphisa i-excitation current emva komda wexesha le-T1 (5s) (isiphumo sokunciphisa i-excitation current ayinamsebenzi);Uphawu lwesenzo somda wexesha eliguqukileyo lumiselwa ngokomthamo ogqithisiweyo we-winding evuselela ijenereyitha, kwaye isenzo sokhuseleko kukukhupha uloliwe.Elona xesha liphezulu lekhawuntari yimizuzwana eyi-10.

I-Jeneretha ye-rotor yokukhusela indawo yokukhusela

Inqaku elinye lokukhusela i-rotor ye-generator isetyenziselwa ukubonakalisa impazamo yesiseko esisodwa se-generator rotor circuit.Ukhuseleko lwamkela umgaqo wokutshintsha i-ping-pong.I-voltage echanekileyo kunye nengalunganga yesiphaluka se-rotor emhlabeni isampuli ngokulandelelana, kwaye ukuxhathisa i-rotor grounding kunye ne-grounding positioning kubalwa ngexesha langempela ngokusombulula ii-equations zesiphaluka ezimbini ezahlukeneyo.Emva kokulibaziseka kwemizuzwana ye-2, umlindi usebenzisa umqondiso.

Ukhuseleko lomthwalo omninzi we-Symmetric ijenereyitha

Isixhobo sokhuseleko siquka umda wexesha elimiselweyo kunye nomda wexesha elichaseneyo.Icandelo lexesha elimiselweyo imizuzwana emi-5 emva kokusetyenziswa komqondiso.Uphawu lwesenzo sexesha eliguquguqukayo luchongwa ngokomthamo wejeneretha yokumelana nomthwalo ogqithisileyo wangoku, kwaye isenzo kukusombulula ingxaki.Isixhobo sokukhusela sinokubonakalisa inkqubo yokugcinwa kokushisa kwe-generator stator.

Ijenereyitha engalunganga ngokulandelelana kokhuseleko lomthwalo ogqithisiweyo

Isixhobo sokhuseleko siquka umda wexesha elimiselweyo kunye nomda wexesha elichaseneyo.Ixesha elimiselweyo lesenzo sangoku sisetwa ngokulandelelana okungalunganga kwexabiso langoku elivumela i-generator ixesha elide kunye nexabiso langoku ukuphepha ukungalingani kwesihluzo sangoku sokulandelelana okungalunganga phantsi komthwalo omkhulu, kwaye isetyenziswe kwisignali emva kwe-3- ixesha lesibini umda.Uphawu lwesenzo sexesha eliguquguqukayo lumiselwa ngokwamandla ejeneretha yokumelana nolandelelwano olungalunganga lwangoku, kwaye isenzo kukusombulula i-demagnetization.Isixhobo sokukhusela sinokubonakalisa inkqubo yokugcina ukushisa kwe-rotor ye-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, Shanghai, Deutz, Ricardo, MTU, Weichai njl kunye noluhlu lwamandla 20kw-3000kw, kwaye babe ngumzi-mveliso wabo we-OEM kunye neziko lobuchwepheshe.
