(2) Iimfuno zokusingqongileyo zokusetyenziswa kweejeneretha ziphezulu kakhulu kunezo zejenereyitha ezisezantsi;
2, Indlela yokunyusa yeeseti zejeneretha
Kwiindawo ezifuna unikezelo lwe-voltage ephezulu, ngaphezu kokwabelwa iiseti zejeneretha eziphakamileyo, iiseti ze-voltage generator standard kunye ne-step-up transformers nazo zingasetyenziswa.
1. Izinto eziluncedo kwi-Low Voltage ePhantsi ukuya kwi-High Voltage Scheme
(1) Kukho iimfuno zamandla ombane ezimbini okanye ngaphezulu ezahlukeneyo kwindawo yokwakha, okanye umbane ophuma kwiseti yejenereyitha kufuneka itshintshwe;
(2) (Isolation transformation function isolation) Ukuphela kwe-voltage ephezulu yi-angle transformer, kwaye inkqubo yocingo yesigaba sesithathu ayinayo umgca we-zero.Ngaphandle komgca we-zero, akukho kutshintshwa komgca we-zero;Yahlula i-harmonics eveliswa yimithwalo engeyiyo yomgca kwicala le-voltage ephezulu ukusuka kwicala le-voltage ephantsi, ukwenza icala le-voltage ephantsi licoceke kwaye lingachaphazeli ukusebenza kwe-automatic voltage regulator (AVR) ngaphakathi kweseti yejenereyitha, kunye nokusombulula. iingxaki ezahlukeneyo ezibangelwa kukudluliselwa komgca ongu-zero;
3Iziguquli zomthamo omkhulu ziqulethe inani elikhulu lezinto zobhedu, kwaye i-core magnetic enkulu idlala indima ephazamisayo, ukunciphisa impembelelo kwi-generator kunye nokuphucula ukuhla kwamandla ombane ngoko nangoko.
2. Izinto ezingeloncedo kwiSikimu soQhagamshelwano oluFanayo kwiiYunithi zeGenereyitha eziphantsi
Kwisethi ye-380-415Vac generator, ukuba iiseti ezininzi zeejeneretha zixhunyiwe ngokuhambelanayo kwicala eliphantsi-i-voltage kwaye emva koko iphakanyiswe yi-transformer ye-step-up;Umlinganiselo ophezulu ocetyiswayo yi-7500 kVA, 6000 kW.Xa kugqithiswa kumlinganiselo ongaphezulu, le miba ilandelayo kufuneka iqwalaselwe:-
Umthamo we-low-voltage side busbar kufuneka usondele kwi-10kA, kuthathelwa ingqalelo amandla e-busbar yokumelana nemisinga yempazamo kunye nonyango lobushushu ngaphakathi kwi-low-voltage switch (ukunyuka kobushushu besikrini sokutshintsha kwe-low-voltage);
• Umthamo wokukhubeka weeswitshi ze-voltage ephantsi (ukuya kuthi ga kwi-fault currents), ezifana nokuya kuthi ga kwi-65kA kunye ne-100kA;
• Kuyimfuneko ukubala ukuba ukufakelwa kweentambo ze-ampere eziphantse zibe yi-10000, iiswitshi ezine-voltage ephantsi, kunye neendleko kwicala le-low-voltage zifanelekile;
