Iinjini zombane ophezulu dlala indima ebalulekileyo kushishino lwangoku, ingakumbi kumandla aphezulu kunye neziganeko zothumelo lomgama omde. Eli nqaku liza kuphonononga kwiingenelo zokusebenza kweenjini zombane ophezulu kunye neendawo zazo eziphambili zesicelo ukunceda abasebenzisi ukuba baqonde ngcono ixabiso kunye nokhetho lweemoto zombane ophezulu.
- Umgaqo osebenzayo wemoto yombane ophezulu
Umgaqo wokusebenza we-high-voltage motor ngokusisiseko uyafana naleyo ye-low-voltage motor, kwaye undoqo wayo ulele ku-electromagnetic induction. Iinjini zombane eziphezulu zihlala zisebenza kwi-3KV, i-6KV kunye ne-voltages ephezulu, kwaye isakhiwo esiphambili sibandakanya i-stator, i-rotor kunye ne-insulation system. Inkqubo yokusebenza imi ngolu hlobo lulandelayo:
Ukujija isitator:I-stator winding ye-high-voltage motor inxeba nge-multi-coil insulated ucingo lobhedu, olunokumelana nombane ophezulu. Unikezelo lwamandla luvelisa intsimi yamagnetic ejikelezayo ngokusebenzisa i-stator winding ukuqhuba i-rotor ukujikeleza.
Ubume beRotor:I-rotor yemoto ephezulu yombane ingaba yikheji ye-squirrel okanye uhlobo olujikelezayo.I-squirrel-cage rotorisetyenziswa ngokubanzi ngenxa yesakhiwo sayo esilula kunye nokuthembeka okuphezulu, okufanelekileyo kusetyenziso oluqhelekileyo lwamashishini. I-rotor ejikelezayo ifanelekile kwizihlandlo apho ukulawulwa kwesantya okanye i-torque enkulu yokuqala kufuneka.
Imo yokuvuselela:I-excitation ye-high-voltage motors idla ngokufezekiswa ngokuzikhupha okanye ukukhupha ngaphandle. I-self-excited high-voltage motors ixhomekeke kwi-stator windings ukubonelela ngokuqhubekayo, ngelixa ii-motor ezinomdla zangaphandle zifuna ukubonelela ngokukhupha amandla ngokusebenzisa umthombo wamandla wangaphandle.
- Yenzaeiingenelo zemoto yombane ophezulu
Ukonga amandla kunye nokhuseleko lokusingqongileyo:Imoto yamandla ombane aphezulu kumandla afanayo, langoku iphantsi, enokunciphisa ilahleko yamandla ombane, ibonelele ngobuchule obuphezulu bamandla, ngokuhambelana nendlela yangoku yokonga amandla kunye nokunciphisa ukukhutshwa kombane.
Nciphisa iindleko zezinto:Imoto yamandla ombane aphezulu inokusebenza kumbane ophezulu, amandla afanayo etyala, indawo enqamlezileyo yocingo efunekayo incinci, ngaloo ndlela inciphisa ukusetyenziswa kweentambo kunye nezixhobo zokugquma, ukonga iindleko zokuvelisa.
Ukunyamezela umthwalo ophezulu:Uyilo lweenjini zombane ophezulu zibavumela ukuba baqhube kakuhle ekuqaliseni nzima kunye nokusebenza, ngakumbi kwizixhobo ezifuna itorque ephezulu.
Inxalenye encinci yentambo yomnqamlezo:Iinjini eziphezulu ze-voltage zingasebenzisa iintambo ezinamacandelwana amancinci anqamlezayo ngenxa yombane omncinci, onciphisa utyalo-mali lweentambo xa uhambisa amandla kumgama omde.
- Ezona ndawo zisetyenziswayo zemoto yombane ophezulu
Iinjini zombane ophezulu zisetyenziswa ngokubanzi kumashishini amaninzi, kwaye ezona ndawo zisetyenziswayo zibandakanya:
Ukumbiwa kwemigodi: Ekuphakamiseni, ukuthutha kunye nokuchoboza izixhobo kwimigodi, ii-motor high-voltage zingumthombo oyintloko wamandla, okwazi ukusebenza ngokuzinzile kwiindawo ezinzima.
Imichiza kunye nepetrochemical:Kwimveliso yeekhemikhali, iinjini zombane eziphezulu zisetyenziselwa ukuqhuba izixhobo ezahlukeneyo zoomatshini, ezinjengeempompo, iicompressors kunye nabalandeli, ukuqinisekisa ukusebenza kakuhle kwenkqubo yokuvelisa.
Ishishini lamandla:Iinjini eziphezulu ze-voltage zisetyenziselwa kwizityalo zamandla kunye neendawo ezincinci zokuqhuba iijeneretha, ii-transformers kunye nezinye izixhobo zokuqinisekisa ukusebenza okuzinzile kwenkqubo yamandla.
Ukucocwa kwamanzi: Kwizityalo zokucocwa kwamanzi amdaka kunye nezikhululo zokumpompa amanzi,iinjini zoxinzelelo oluphezulu zisetyenziselwa ukuqhuba iimpompo ukuhlangabezana neemfuno zokuhanjiswa kwamanzi ahambayo amakhulu.
- Ukugcinwa kunye nokugcinwa kweemoto zamandla aphezulu
Ukuze kuqinisekiswe ukusebenza okuzinzileyo kwexesha elide lemoto yombane ophezulu, ukugcinwa rhoqo kunye nokugcinwa kubaluleke kakhulu. Nanga amanye amanqaku aphambili okugcinwa kwamandla ombane aphezulu:
Ukuhlolwa kwe-Insulation:Rhoqo ujonge izinto zokugquma i-motor ukuqinisekisa ukuba zikwimeko entle yokusebenza ukuthintela ukungaphumeleli okubangelwa kukungaphumeleli kokugquma;
Ukujongwa kobushushu:Xa i-motor ye-voltage ephezulu isebenza, ubushushu bemoto buhlala bubekwe esweni ukuze kuqinisekiswe ukuba kuluhlu olukhuselekileyo kwaye luthintele umonakalo obangelwa kukufudumala.
Ukucoca kunye nokugcinwa:Gcina i-motor ngaphandle kunye nenkqubo yokungenisa umoya icocekile, thintela uthuli kunye ne-debris ithintela ukutshatyalaliswa kobushushu, okuchaphazela ukusebenza kwemoto.
Ulawulo lokuthambisa:Qwalasela kwaye utshintshe ioyile yokuthambisa imotor ukunciphisa ukukhuhlana kunye nokunxiba kunye nokwandisa ubomi bemoto.
Ngokusebenzisa amanyathelo okugcinwa kwesayensi, abasebenzisi banokuqinisekisa ukusebenza ngokufanelekileyo kweenjini zevoltage ephezulu kunye nokunciphisa ukuphindaphindeka kokusilela.
Ngokusebenza kwayo okuphezulu kunye nokusetyenziswa okubanzi, iimoto zombane ophezulu ziye zaba sisixhobo samandla esiyimfuneko kwishishini lanamhlanje.
