Zofunikira za Kutentha kwa Jenereta ndi Kuziziritsa

Monga gwero lamphamvu ladzidzidzi, jenereta ya dizilo iyenera kugwira ntchito mosadodometsedwa kwa nthawi yayitali pakagwiritsidwe ntchito.Ndi katundu waukulu wotere, kutentha kwa jenereta kumakhala vuto.Kuti ntchito isasokonezeke bwino, kutentha kuyenera kusungidwa m'malo oyenera.Mkati mwa izi, kotero tiyenera kumvetsetsa zofunika kutentha ndi njira kuzirala.

1. Zofunikira za kutentha

Malinga ndi mitundu yosiyanasiyana yotchinjiriza ya ma jenereta a dizilo, kukwera kwa kutentha kumasiyana.Nthawi zambiri, kutentha kwa stator winding, field winding, iron core, collector ring ndi pafupifupi 80 ° C pamene jenereta ikugwira ntchito.Ngati ipitilira, ndiye Kutentha kwapamwamba kwambiri.

2. Kuziziritsa

Mitundu yosiyanasiyana ndi mphamvu zamajenereta zimakhala ndi mitundu yosiyanasiyana yozizirira.Komabe, njira yozizirira yomwe imagwiritsidwa ntchito nthawi zambiri imakhala mpweya, haidrojeni, ndi madzi.Tengani jenereta ya turbine synchronous mwachitsanzo.Dongosolo lake lozizirira limatsekedwa, ndipo sing'anga yozizira imagwiritsidwa ntchito pozungulira.

① Kuziziritsa mpweya

Kuziziritsa mpweya kumagwiritsa ntchito fani kutumiza mpweya.Mpweya wozizira umagwiritsidwa ntchito kuwomba kumapeto kwa mafunde a jenereta, stator ya jenereta ndi rotor kuti awononge kutentha.Mpweya wozizira umatenga kutentha ndipo umasanduka mpweya wotentha.Akaphatikizana, amatulutsidwa kudzera munjira ya mpweya wapakati pachitsulo ndikuzimitsidwa ndi chozizira.Mpweya wozizirawo umatumizidwa ku jenereta kuti ubwezeretsedwenso ndi fani kuti ukwaniritse cholinga cha kutentha.Majenereta apakati ndi ang'onoang'ono ama synchronous nthawi zambiri amagwiritsa ntchito kuziziritsa mpweya.

② Kuzizira kwa haidrojeni

Kuziziritsa kwa haidrojeni kumagwiritsa ntchito haidrojeni ngati sing'anga yozizirira, ndipo kutulutsa kutentha kwa haidrojeni ndikwabwino kuposa mpweya.Mwachitsanzo, majenereta ambiri a turbo amagwiritsa ntchito haidrojeni pozizirira.

③ Kuziziritsa madzi

Kuziziritsa kwamadzi kumatengera njira yozizirira yamkati ya stator ndi rotor.Madzi ozizira a dongosolo la madzi a stator amayenda kuchokera kumadzi akunja kupyolera mu chitoliro cha madzi kupita ku mphete yamadzi yolowera pa stator, ndiyeno amapita ku ma coils kupyolera mu mapaipi otsekedwa.Pambuyo kuyamwa kutentha, amasonkhanitsidwa ndi insulated madzi chitoliro kwa madzi kubwereketsa mphete anaika pa chimango.Kenako amatulutsidwa m'madzi akunja kwa jenereta kuti aziziziritsa.Kuziziritsa kwa dongosolo lamadzi la rotor kumayamba kulowa m'malo olowera madzi omwe amayikidwa kumapeto kwa shaft ya exciter, ndiyeno kumathamangira m'dzenje lapakati la shaft yozungulira, kumayenda m'mabowo angapo oyambira kupita ku thanki yosonkhanitsa madzi, kenako ndikuyenderera kupita zozungulira kudzera mu insulating chubu.Madzi ozizira akamayamwa kutentha, amalowa mu thanki yotulutsiramo kudzera mu chitoliro chotsekeredwa, kenako amathamangira kumalo otulutsirako kudzera pabowo lakunja kwa thanki, ndikutsogozedwa ndi chitoliro chachikulu chotulutsira.Popeza kuti kutentha kwa madzi ndikokwera kwambiri kuposa mpweya ndi haidrojeni, jenereta wamkulu watsopano nthawi zambiri amagwiritsa ntchito kuziziritsa madzi.
