Ziziphi iimpembelelo zeLahleko yoVuso kwiGenereyitha

Ngethuba lokusebenza okuqhelekileyo kwejenereyitha, ukutshatyalaliswa ngokukhawuleza kuyanyamalala ngokupheleleyo okanye ngokuyinxenye, okubizwa ngokuba yilahleko ye-excitation ye-generator.

Phakathi kwamacandelo esethi ye-diesel generator, i-generator ibaluleke kakhulu.Emva kwexesha elide lokusetyenziswa kwesethi yejenereyitha ye-diesel, i-generator inokulahlekelwa yimincili.Le meko iqhelekile.Kodwa le meko iya kuchaphazela inkqubo. Ziziphi iimpembelelo zelokhwe evuselelayo kwijenereyitha?

I-1.I-Low-excitation kunye nokulahlekelwa kwe-excitation generators ithatha amandla asebenzayo kwi-system, ebangela ukuba i-voltage yenkqubo yamandla yehle.Ukuba ugcino lwamandla asebenzayo kwinkqubo yamandla ayonelanga, umbane wamanye amanqaku kwisixokelelwano samandla uya kuba ngaphantsi kunexabiso elivumelekileyo litshabalalisa ukusebenza okuzinzileyo phakathi komthwalo kunye nomthombo wamandla ngamnye, kwaye ibangele nokuba umbane wenkqubo yamandla ukuwa.

2.Xa ijenereyitha ilahlekelwa ngumdla wayo, ngenxa yokuhla kwamandla ombane, ezinye iijeneretha kwinkqubo yamandla ziya kwandisa amandla azo asebenzayo phantsi kwesenzo sohlengahlengiso oluzenzekelayo lwesixhobo sokuvuselela, ngaloo ndlela kubangele ezinye. iijenereyitha , i-transformers okanye imigca kwi-overcurrent , Ukukhuselwa kwayo kwe-backup inokusebenza kakubi ngenxa ye-overcurrent, eya kwandisa ububanzi bengozi.

3.Emva kokuba ijenereyitha ilahlekelwe nguzibuthe, ngenxa yokujinga kwamandla asebenzayo ejenereyitha kunye nokuhla kwamandla ombane wenkqubo, kunokubangela ukuba iijenereyitha zokusebenza eziqhelekileyo ezikufuphi kunye nenkqubo, okanye phakathi kweendawo ezahlukeneyo zenkqubo yamandla, ziphulukane. ungqamaniso, obangela inkqubo ukuba ilahlekelwe lungqamaniso.I-oscillation iyenzeka.

4.Okukhona ubungakanani bomthamo olinganisiweyo wejenereyitha, kokukhona ukusilela kombane osebenzayo okubangelwa kukuvuseleleka okuphantsi kunye nokulahleka kovuselelo, kunye nokuncinci umthamo wenkqubo yamandla, okukhona kuncinci ukukwazi ukubuyisela le ntsilelo yamandla asebenzayo.Ke ngoko, okukhona umlinganiselo omkhulu womthamo wejenereyitha enye ukuya kumthamo uwonke wenkqubo yamandla, kokukhona ifuthe elibi kwinkqubo yamandla.

Sisiphi isizathu sokulahlekelwa yi-excitation ye-generator?

(1) Uphawu emva kokuba i-generator ilahlekelwe yi-excitation yayo: i-stator yangoku kunye namandla asebenzayo e-generator iphakama ngokukhawuleza emva kokuhla ngokukhawuleza, kwaye umlinganiselo uyanda kwaye uqala ukuguquka.

(2) Ijenereyitha isenako ukuthumela isixa esithile samandla asebenzayo emva kokulahleka kovuselelo, kwaye igcine isalathiso samandla asebenzayo athunyelweyo, kodwa isalathisi semitha yamandla siyaguquka ngamaxesha athile.

(3) Njengoko i-stator yangoku isanda, isalathisi se-ammeter saso siphinda sijinge.

(4) Ukusuka kumandla asebenzayo athunyelweyo ukuya kumandla asebenzayo afunxwayo, isalathisi sibuye sijinge ngamaxesha athile.Ubungakanani bamandla asebenzayo afunnyiweyo buphantse bulingane nesixa samandla asebenzayo phambi kokulahleka kovuselelo.

(5) Isekethe ye-rotor idala amandla atshintshayo akhoyo kunye ne-magnetomotive yangoku kunye ne-slip frequency, ngoko ke isalathisi se-rotor voltmeter siphinda sijinge ngamaxesha athile.

(6) Isalathiso se-ammeter ye-rotor nayo i-oscillates ngamaxesha, kwaye ixabiso langoku lincinci kunelo ngaphambi kokulahlekelwa yi-excitation.

(7) Xa i-circuit ye-rotor ivuliwe, i-eddy yangoku ethile iqhutywe kumphezulu womzimba we-rotor ukwenza intsimi yamagnetic ejikelezayo, ephinda ivelise inani elithile lamandla asynchronous.

Indlela yokujongana nengxaki yokulahlekelwa yi-excitation ye-generator?

(1) Emva kokuba ukulahlekelwa kokhuseleko lokuvuselela kusebenze, imodi yokuvuselela iguqulwa ngokuzenzekelayo, kwaye ukunciphisa umthwalo osebenzayo akuvumelekile kwaye kusebenza kuhambo, kuya kusingathwa njengokuvalwa kwengozi;

(2) Ukuba i-de-excitation switch ikhutshwe ngempazamo, i-de-excitation switch kufuneka iphinde ivalwe ngokukhawuleza.Ukuba ukuvala kwakhona akuphumelelanga, i-generator iya kukhutshelwa kwaye imiswe ngokukhawuleza;

(3) Ukuba ukulahleka kwe-excitation ngenxa yokungaphumeleli kwe-excitation regulator AVR, tshintshela ngokukhawuleza i-AVR ukusuka kwitshaneli esebenzayo ukuya kwisitishi sokulinda, kwaye utshintshele ekusebenzeni ngesandla ukuba imo ezenzekelayo iyahluleka;

(4) Emva kokuba i-generator ilahlekelwe yimincili kwaye i-generator ayihambi, umthwalo osebenzayo kufuneka uthotywe ube yi-120MW ngaphakathi kwe-1.5min, kunye nexesha elivumelekileyo lokugijima emva kokulahlekelwa kwemagnetism yi-15min;

(5) Ukuba ukulahlekelwa kwe-excitation kubangela ukuba i-generator i-oscillate, i-generator kufuneka ikhutshwe kwaye ivalwe ngokukhawuleza, kwaye iphinde idibaniswe kwigridi emva kokuba i-excitation ibuyiselwe.

Xa i-generator ilahleka kwi-excitation, kufuneka sifumane isizathu kunye nokusombulula ingxaki ngexesha, ukuphepha impembelelo kwi-generator.I-Dingbo Power ayinikeli kuphela inkxaso yobugcisa, kodwa ivelise kwakhona iiseti generator diesel , ukuba unesicwangciso sokuthenga, wamkelekile ukuba uqhagamshelane nathi nge-imeyile dingbo@dieselgeneratortech.com.
