Uyenza njani iMajeneyitha

Ukuba ijenereyitha ayinamagneti, inokwenziwa nguzibuthe ngebhetri eyi-12V.Indlela ethile yile: qhagamshela iingcingo ezimbini ukusuka kwi- + - pole yebhetri.Vula i-case yentsimbi ekhuselekileyo yebhodi yesiphaluka yokulawula i-generator.Qala ijenereyitha.Qhagamshela i-+ - pole ku-F + F - (yebhodi yesekethe yolawulo lwejenereyitha, kwaye ixesha loqhagamshelo aliyi kudlula umzuzwana omnye. Emva kwemagneti, jonga umbane kunye namaxesha. Qaphela ukuba ijenereyitha ayinakulayishwa phambi kokuba imagneti ifakwe igqitywe, kwaye ke inokulayishwa emva kokuba ikhangelwe ukuba yesiqhelo.Omnye umcimbi kukuqalisa ijenereyitha kwaye iya kuhlawulisa ngokuzenzekelayo malunga nemizuzu elishumi.

Kodwa ukuba i-generator ilahlekelwa yi-excitation ngenxa yeengxaki zeempazamo, kufuneka siyisombulule ngokweempazamo ezahlukeneyo.

Yintoni unobangela wokulahleka kwejenereyitha yovuselelo?

Ngethuba lokusebenza okuqhelekileyo kwejeneretha, ukutshatyalaliswa ngokukhawuleza kuyanyamalala ngokupheleleyo okanye inxalenye, okubizwa ngokuba yilahleko ye-excitation ye-generator.Izizathu zokulahleka kwejenereyitha ye-excitation ngokubanzi zinokushwankathelwa njengesekethe evulekileyo okanye isiphaluka esifutshane sesekethe yokuvuselela, kubandakanya ukusilela kwe-exciter, i-excitation transformer okanye i-excitation circuit, ukubamba ngengozi kwi-excitation switch, ukutshintshela okungafanelekanga kwe-excitation yokulinda, ukulahlekelwa ngumbane oncedisayo. inkqubo yokuvuselela, isiphaluka esivulekileyo se-rotor winding okanye i-excitation circuit okanye i-circuit short ye-rotor winding, ukungaphumeleli kwenkqubo yokuvuselela i-semiconductor, ukuvutha okanye ukutshiswa kwe-rotor slip ring.

1. I-excitation transformer fault trip ibangela ilahleko yejenereyitha yolonwabo

Ngenxa yesiphene sokwenziwa kwe-insulation ye-transformer okanye ukuwohloka ngokuthe ngcembe kwesiphene sokugquma ngexesha lokusebenza, kwenzeka into yokukhutshwa, okukhokelela ekukhubekeni kwesenzo sokukhusela i-excitation transformer kunye nokukhubeka kweyunithi ngenxa yokulahleka kwesenzo sokukhusela i-excitation.Iinkqubo kunye nemigangatho iya kuphunyezwa ngokungqongqo, kwaye iimvavanyo zarhoqo, ukuphunyezwa kunye nokusombulula ingxaki ziya kwenziwa.Ngokwemigaqo kunye nemigangatho efanelekileyo, ukuphunyezwa kovavanyo lwamaxesha athile loqeqesho lwe-insulation luya kwenziwa ngononophelo.

2. Ilahleko ye-excitation ye-generator ebangelwa kukukhubeka kwe-de excitation switch

Izizathu zohambo lotshintsho lwe-de excitation zibandakanya: (1) umyalelo wohambo we-de excitation switch uthunyelwe ngempazamo kwi-DCS.(2) Umyalelo wokuhamba we-deexcitation switch uthunyelwa ngaphandle kwimeko yempazamo yokuhanjiswa kwe-outlet.(3) Uqhagamshelwano lweqhosha lohambo lwesitshixo sokuphuma kwiphaneli yombane ethe nkqo kwigumbi eliphakathi lolawulo liyatsalwa ukuze kuthunyelwe umyalelo wohambo.(4) Iphaneli yokulawula yendawo yegumbi lokuvuselela ihlula ngesandla i-de excitation switch.(5) I-insulation yentambo yesiphaluka yokulawula ye-de excitation switch ihla.(6) Umzimba wokutshintsha ngoomatshini ukhubekisa iswitshi ye-de excitation.(7) Ukumiswa okukhawulezileyo kwenkqubo ye-DC kubangela ukuba utshintsho lwe-de excitation luhambe.

3. Ukulahleka kovuselelo lwejenereyitha okubangelwa kukutsha kweringi ye-excitation slip

Unobangela wengozi yayikukuba uxinzelelo lwe-carbon brush compression spring lwalungalingani, nto leyo ebangele ukusasazwa kokungalingani kwangoku kwezinye iibhrashi zekhabhoni, okukhokelela ekugqithiseni ngokugqithisileyo kweebhrashi zekhabhoni kunye nokubangela ubushushu.Ukongeza, ibrashi yekhabhoni imdaka, ingcolisa umphezulu wonxibelelwano webrashi yekhabhoni kunye neringi yokutyibilika, ibangela ukuxhathisa koqhagamshelwano kwezinye iibhrashi zekhabhoni kunye neringi yokutyibilika yanda kwaye emva koko intlantsi.Ukongeza, ukunxitywa kweebrashi zekhabhoni ezilungileyo kunye nezingalunganga azilingani, kwaye ukunxiba kwe-electrode engalunganga kuhlala kubi kakhulu kune-electrode entle.Uburhabaxa bomphezulu bomsesane wokutyibilika buyanda ngenxa yokunxitywa okunzulu, kunye nomlilo weringi wokutyibilika ubangelwa ngenxa yokusilela ukulawula ngexesha.

4. Ukulahleka kovuselelo lwejenereyitha okubangelwa kukumisa inkqubo ye-DC

Emva kokumiswa kwe-electrode elungileyo yenkqubo ye-DC, intambo ende isasaze amandla, kwaye amandla ombane kwiziphelo zombini ze-capacitance ayinakutshintsha ngequbuliso, nto leyo ebangela ukuba i-capacitance yangoku yentambo ende kwisekethe yangaphandle ye-generator deexcitation switch to. ukugeleza kwi-relay ephakathi kwindawo yokuphuma yangaphandle, kwaye i-relay ithatha isenzo sokutshintsha i-generator deexcitation switch, ekhokelela ekukhubekeni kwesenzo sokukhusela i-generator deexcitation.

5. Ukulahlekelwa yi-excitation yejenereyitha okubangelwa yimpazamo yenkqubo yokulawula i-excitation

Impazamo yebhodi ye-EGC yomlawuli wenkqubo yokuvuselela i-generator ibangele isenzo sokukhusela i-voltage engaphezulu kwe-rotor ye-generator excitation regulator, okubangelwa ukukhubeka kokulahleka kwesenzo sokukhusela.
