Umsebenzi we-Transformer ohlelweni lwe-Wind Turbine
Amandla omoya asephenduke umthombo wamandla avuselelekayo okhula ngokushesha emazweni ahlukahlukene, okuhlanganisa ne-Indonesia. Ama-turbine omoya aguqula amandla e-kinetic omoya abe amandla kagesi angasetshenziswa yimindeni, izimboni, ngisho namagridi amakhulu kagesi. Kodwa-ke, inqubo yokukhiqiza ugesi kusuka ku-turbine yomoya ayigcini kujeneretha. Imishini ebalulekile evame ukunganakwa yi-transformer. I-transformer idlala indima ebalulekile ekuqinisekiseni ukuthi ugesi okhiqizwa yi-turbine yomoya usatshalaliswa ngokuphepha, ngempumelelo, nangokuhambisana nezindinganiso zegridi.
Ukubuka Konke Kwesistimu Ye-Wind Turbine
Ngokuvamile, i-wind turbine iqukethe i-rotor (blade), i-nacelle (indlu yengxenye eyinhloko), i-shaft, i-gearbox (kwezinye izinhlobo), i-generator, uhlelo lokulawula, nezinye izingxenye zikagesi. Lapho umoya uphendula i-rotor, amandla omshini adluliselwa ku-generator ukuze akhiqize ugesi. Lo gesi ngokuvamile usesimweni se-alternating current (AC) enezici ezithile, njenge-voltage kanye nemvamisa, ezingahluka kuye ngesivinini somoya kanye nohlobo lwe-generator.
Yilapho izinhlelo zokuguqulwa kwamandla kanye nama-transformer zisebenza khona. Ukuze ulethe ugesi kumthwalo noma kugridi, i-voltage kumele ilungiswe, ikhwalithi yamandla ithuthukiswe, futhi ukulahlekelwa kokudlulisela kuncishiswe. Ama-transformer ayisisombululo esiyinhloko salezi zidingo.
Iyini i-Transformer futhi kungani idingeka?
I-transformer iyithuluzi likagesi elandisa noma elinciphisa i-AC voltage kusetshenziswa isimiso sokungeniswa kwe-electromagnetic. Ama-transformer awakhiqizi amandla, kodwa kunalokho ashintsha amazinga e-voltage ukuze amandla kagesi adluliselwe kahle.
Uma kukhulunywa ngama-wind turbine, ama-generator output voltage ngokuvamile asezingeni eliphakathi noma eliphansi (isb., amakhulu ama-volts kuya kuma-kilovolts ambalwa). Okwamanje, amanethiwekhi okusatshalaliswa kukagesi kanye nokudlulisa adinga amazinga aphezulu e-voltage (isb., 20 kV, 33 kV, 70 kV, noma ngaphezulu). Ngaphandle kwama-transformer, ugesi ovela kuma-wind turbine ubungaba nzima ukuwudlulisa amabanga amade ngoba imisinga ephezulu ibingabangela ukulahlekelwa okukhulu kanye nokushisa okukhulu ezintanjeni.
Umsebenzi Oyinhloko We-Transformer Kuhlelo Lwe-Wind Turbine
