Iseti yejenereyitha ngokubanzi ibandakanya injini, ijenereyitha, inkqubo yolawulo ebanzi, inkqubo yesekethe yeoli, kunye nenkqubo yokuhambisa amandla.Inxalenye yamandla yejeneretha ebekwe kwinkqubo yonxibelelwano - i-injini ye-diesel okanye i-injini ye-turbine ye-gas - ngokusisiseko iyafana kuxinzelelo oluphezulu kunye neeyunithi zoxinzelelo oluphantsi;Ukucwangciswa kunye nomthamo wepetroli wenkqubo yeoli inxulumene kakhulu namandla, ngoko akukho mmahluko obalulekileyo phakathi kweeyunithi zoxinzelelo oluphezulu kunye noluphantsi, ngoko ke akukho mahluko kwiimfuno zokungenisa umoya kunye neenkqubo zokukhupha iiyunithi ezibonelela ngokupholisa.Umahluko kwiiparameters kunye nokusebenza phakathi kweesethi zejeneretha eziphezulu kunye ne-low-voltage generator sets zibonakaliswa ngokukodwa kwi-generator inxalenye kunye nenkqubo yokusabalalisa inxalenye.
1. Umahluko kumthamo kunye nobunzima
Iiseti zejenereyitha zombane ophezulu zisebenzisa iijenereyitha ezinevoltage ephezulu, kwaye ukonyuka komgangatho wombane kwenza ukuba iimfuno zabo zokugquma zibe phezulu.Ngokuhambelanayo, umthamo kunye nobunzima benxalenye yejeneretha zikhulu kunezo zeeyunithi ezisezantsi.Ngoko ke, umthamo womzimba uwonke kunye nobunzima beseti yejenereyitha ye-10kV bukhulu kancinane kunobo beyunithi yombane ophantsi.Akukho mahluko ubalulekileyo kwinkangeleko ngaphandle kwenxalenye yejeneretha.
2. Umahluko kwiindlela zokumisa
Iindlela zokumisa ezingathathi hlangothi zeesethi ezimbini zejeneretha ziyahluka.Ukujija kweyunithi ye-380V yinkwenkwezi edibeneyo.Ngokuqhelekileyo, inkqubo ye-low-voltage yinkqubo yokumisa ngokuthe ngqo kwinqanaba elingathathi hlangothi, ngoko ke inkwenkwezi idibanise indawo engathathi hlangothi yejeneretha imiselwe ukurhoxiswa kwaye inokusekwa ngokuthe ngqo xa kuyimfuneko.Inkqubo ye-10kV yinkqubo encinci yomhlaba yangoku, kwaye indawo engathathi hlangothi ayisekelwanga okanye isekelwe phantsi ngenxa yokuxhathisa.Ngoko ke, xa kuthelekiswa neeyunithi eziphantsi kwe-voltage, iiyunithi ze-10kV zifuna ukongezwa kwezixhobo zokusabalalisa iindawo ezingathathi hlangothi ezifana neekhabhinethi zokumelana kunye neekhabhinethi zoqhagamshelwano.
3. Umahluko kwiindlela zokukhusela
Iisethi zejeneretha zombane ophezulu ngokubanzi zifuna ukufakelwa kokhuseleko olukhawulezayo lwangoku, ukukhuselwa komthwalo ogqithisileyo, ukukhuselwa komhlaba, njl.
Xa i-grounding iphosakele ekusebenzeni kwe-high-voltage generator set, ibeka ingozi enkulu yokhuseleko kubasebenzi kunye nezixhobo, ngoko ke kuyimfuneko ukuseta ukukhuselwa kwempazamo yomhlaba.
Indawo engathathi hlangothi yejeneretha isekelwe kwi-resistor.Xa i-single-phase-grounding iphoso yenzeke, i-foult current ejikelezayo kwindawo engathathi hlangothi ingabonwa, kwaye ukukhubeka okanye ukukhuselwa kokuvalwa kunokufezekiswa ngokukhuselwa kwe-relay.Indawo engathathi hlangothi yejeneretha isekelwe kwi-resistor, enokuthi inciphise i-foult current ngaphakathi kwe-curve yomonakalo ovumelekileyo we-generator, kwaye i-generator inokusebenza ngeempazamo.Ngokuxhathisa ukumisa, iziphene zokumisa zingabonwa ngokufanelekileyo kwaye izenzo zokukhusela i-relay zingaqhutywa.Xa kuthelekiswa neeyunithi eziphantsi kwe-voltage, iiseti ze-generator high-voltage zifuna ukongezwa kwezixhobo zokusabalalisa iindawo ezingathathi hlangothi ezifana neekhabhinethi zokumelana kunye neekhabhinethi zoqhagamshelwano.
Ukuba kuyimfuneko, ukukhuselwa okungafaniyo kufuneka kufakwe kwiisethi ze-generator high-voltage.
Ukubonelela ngokhuseleko oluhlukeneyo lwangoku lwamanqanaba amathathu kwi-stator winding ye-generator.Ngokufakela ii-transformers zangoku kwii-terminals ezimbini eziphumayo zekhoyili nganye kwi-generator, umahluko okhoyo phakathi kwee-terminals ezingenayo neziphumayo zekhoyili ulinganiswa ukugqiba imeko yokukhusela i-coil.Xa isiphaluka esifutshane okanye isiseko senzeke kuzo naziphi na izigaba ezimbini okanye ezintathu, i-fault current ingabonwa kuzo zombini ii-transformers, ngaloo ndlela ikhuselwa.
4. Umahluko kwiintambo zemveliso
Ngaphantsi komgangatho ofanayo womthamo, i-diameter ye-outlet cable ye-high-voltage units incinci kakhulu kuneeyunithi ze-low-voltage, ngoko ke iimfuno zomsebenzi wendawo kwiitshaneli zokuphuma ziphantsi.
5. Umahluko kwiiNkqubo zoLawulo lweYunithi
Inkqubo yokulawula iyunithi yeeyunithi eziphantsi kwe-voltage ingadityaniswa ngokubanzi kwicala elinye lecandelo le-generator kumzimba womatshini, ngelixa iiyunithi eziphezulu ze-voltage zifuna ngokubanzi ibhokisi yokulawula iyunithi ezimeleyo ukuba ihlelwe ngokwahlukileyo kwiyunithi ngenxa yeengxaki zokuphazamiseka komqondiso.
6. Umahluko kwiimfuno zolondolozo
Iimfuno zokugcinwa kweeyunithi ze-high-voltage generator kwiinkalo ezahlukeneyo ezifana nenkqubo yesekethe yeoli kunye nenkqubo yokungenisa umoya kunye nenkqubo yokukhupha ilingana naleyo yeeyunithi eziphantsi-voltage, kodwa ukuhanjiswa kwamandla kweeyunithi yinkqubo ephezulu yombane, kunye nabasebenzi bokulondoloza. kufuneka ixhotyiswe ngeemvume zokusebenza ezinombane ophezulu.
