Iyini Imithelela Yokulahlekelwa Kwenjabulo Kujeneretha

Ngesikhathi sokusebenza okuvamile kwe-generator, ukuvuswa kuyanyamalala ngokuzumayo noma kancane, okubizwa ngokuthi ukulahlekelwa kwe-excitation ye-generator.

Phakathi kwezingxenye zesethi ye-generator diesel, i-generator ibaluleke kakhulu.Ngemva kokusetshenziswa isikhathi eside kwesethi yejeneretha yedizili, ijeneretha ingase ilahlekelwe injabulo.Lesi simo sijwayelekile.Kodwa lesi simo sizothinta uhlelo. Iyini imithelela yokulahlekelwa kwe-excitation ku-generator?

1.Amajeneretha ane-excitation ephansi kanye nokulahlekelwa yi-excitation amunca amandla asebenzayo ohlelweni, okubangela ukuba i-voltage yesistimu yamandla yehle.Uma indawo yokugcina amandla asebenzayo ohlelweni lwamandla inganele, i-voltage yamanye amaphuzu kusistimu yamandla izoba ngaphansi kunevelu elivumelekile licekela phansi ukusebenza okuzinzile phakathi komthwalo kanye nomthombo wamandla ngamunye, futhi libangele ngisho ne-voltage yesistimu yamandla ukuthi bhidlika.

2.Lapho ijeneretha ilahlekelwa yinjabulo yayo, ngenxa yokwehla kwamandla kagesi, amanye amajeneretha ohlelweni lwamandla azokwandisa ukuphuma kwawo kwamandla asebenzayo ngaphansi kwesenzo sokulungiswa okuzenzakalelayo kwedivayisi evusa amadlingozi, ngaleyo ndlela kubangele ezinye. amajeneretha , ama-transformer noma imigqa eya ku-overcurrent , Isivikelo saso sokulondoloza singase singasebenzi kahle ngenxa ye-overcurrent, okuzokwandisa ububanzi bengozi.

3. Ngemuva kokuthi i-generator ilahlekelwe ukudonsa kwayo, ngenxa yokushwibeka kwamandla asebenzayo ejeneretha kanye nokwehla kwamandla kagesi wesistimu, kungase kubangele ukulahlekelwa amajeneretha asebenzayo aseduze nesistimu, noma phakathi kwezingxenye ezihlukahlukene zesistimu yamandla, ukulahlekelwa. ukuvumelanisa, okwenza isistimu ilahlekelwe ukuvumelanisa.I-oscillation iyenzeka.

4.Uma sikhulu umthamo olinganisiwe wejeneretha, kukhulu ukushoda kwamandla asebenzayo okubangelwa isasasa eliphansi kanye nokulahlekelwa yinjabulo, kanye nomthamo wesistimu yamandla mancane, ikhono lokunxephezela lokhu kuncipha kwamandla asebenzayo mancane.Ngakho-ke, uma sikhulu isilinganiso somthamo we-generator eyodwa kumthamo ophelele wesistimu yamandla, kuba mkhulu kakhulu umthelela omubi ohlelweni lwamandla.

Siyini isizathu sokulahlekelwa yi-excitation ye-generator?

(1) Uphawu ngemva kokuba ijeneretha ilahlekelwa injabulo yayo: amandla e-stator amanje namandla asebenzayo ejeneretha akhuphuka ngokushesha ngemva kokuwa osheshayo, futhi isilinganiso siyakhula futhi siqala ukushwiba.

(2) Ijeneretha isengathumela inani elithile lamandla asebenzayo ngemva kokulahlekelwa yinjabulo, futhi igcine isiqondiso samandla asebenzayo ethunyelwe, kodwa isikhombi semitha yamandla siyashintshashintsha ngezikhathi ezithile.

(3) Njengoba i-stator current ikhula, i-ammeter pointer nayo iyashintshashintsha ngezikhathi ezithile.

(4) Kusukela emandleni asebenzayo athunyelwe kuya emandleni asebenzayo amuncwa, isikhombisi sibuye sinyakaze.Inani lamandla asebenzayo elimuncwa licishe lilingane nenani lamandla asebenzayo ngaphambi kokulahlekelwa yinjabulo.

(5) Umjikelezo we-rotor uheha amandla ashintshayo wamanje nashintshanayo amagnetomotive anefrikhwensi yokushelela, ngakho-ke isikhombi se-voltmeter ye-rotor siphinde sinyakaze.

(6) Isikhombi se-ammeter yerotor siphinde sijike ngezikhathi ezithile, futhi inani lamanje lincane kunalelo ngaphambi kokulahlekelwa yinjabulo.

(7) Uma isifunda se-rotor sivulekile, i-eddy current ethile ifakwa ebusweni bomzimba we-rotor ukuze yakhe insimu yamagnetic ejikelezayo, ebuye ikhiqize inani elithile lamandla asynchronous.

Indlela yokubhekana nenkinga yokulahlekelwa yi-excitation ye-generator?

(1) Ngemuva kokuthi ukulahleka kokuvikela okuvusa amadlingozi kwenziwe kusebenze, imodi yokuvusa ishintsha ngokuzenzakalelayo, futhi ukuncishiswa komthwalo okusebenzayo akuvumelekile futhi kusebenza ohambweni, kuzophathwa njengokuvalwa kwengozi;

(2) Uma iswishi yokususa isasasa iwiswe ngephutha, iswishi yokususa isasasa kufanele ivalwe kabusha ngokushesha.Uma ukuvala kabusha kungasebenzi, i-generator izokhishwa futhi imiswe ngokushesha;

(3) Uma ukulahlekelwa yizinto ezivusa amadlingozi kungenxa yokwehluleka kwe-AVR yesilawuli esivusa amadlingozi, shintsha ngokushesha i-AVR isuke esiteshini esisebenzayo iye esiteshini esilindile, bese ushintshela ekusebenzeni mathupha uma imodi ezenzakalelayo ihluleka;

(4) Ngemva kokuba i-generator ilahlekelwa ukukhuthazwa futhi i-generator ingakhubeki, umthwalo osebenzayo kufanele wehliswe ube ngu-120MW phakathi kwe-1.5min, futhi isikhathi esivumelekile sokugijima ngemva kokulahlekelwa yi-magnetism yi-15min;

(5) Uma ukulahlekelwa kwe-excitation kubangela ukuba i-generator iguqe, i-generator kufanele inqanyulwe futhi ivalwe ngokushesha, bese iphinde ixhunywe kugridi ngemva kokubuyiselwa kokuvuselela.

Lapho i-generator kwenzeka ukulahlekelwa injabulo, kufanele sithole isizathu futhi sixazulule inkinga ngesikhathi, ukugwema umthelela ku-generator.I-Dingbo Power ayinikezi nje kuphela ukwesekwa kwezobuchwepheshe, kodwa futhi ikhiqize amasethi generator diesel , uma unecebo lokuthenga, wamukelekile ukusithinta nge-imeyili dingbo@dieselgeneratortech.com.
