Isivikelo se-generator kanye nokuvikela okuyisipele

Izinhlobo ezahlukene zamajeneretha zinezivikelo ezihlukene.Isibonelo, isivikelo sejeneretha esingu-30MW sinokulandelayo: umehluko, umkhawulo wesikhathi sokunqamuka, amandla kagesi ayinhlanganisela phezu kwamanje, ukulahleka kukazibuthe, ukugcwala ngokweqile ukuze kuhambe.Izinga lokushisa eliphezulu, ukugcwala ngokweqile, i-alamu ephansi yesigaba esisodwa.

1, isivikelo esikhulu sejeneretha: shintsha umehluko weqembu (umehluko omkhulu), umehluko wejeneretha (umehluko), umehluko oguquguqukayo wejeneretha.

(1) Ukuvikela okuhlukile kobude..

(2) ukunqamula ukuvikelwa kwesifunda esifushane.

a.I-Stator winding yesigaba esisodwa sokuvikela phansi.

b, i-rotor winding isivikelo somhlaba.
c, ukuvikelwa kokulahlekelwa ngugesi kazibuthe.

2, ukuvikelwa kwekhophi yasenqolobaneni: ukuqala kokuhluleka (gxuma ukuvikelwa kokushintshwa kwezinga eliphezulu).

Okusho ukuthi: Uma isenzo sokuvikela ijeneretha, umphumela uba ukuthi isivikelo sejeneretha noma iswishi sinqatshiwe, asikwazi ukuhamba esitobhini.Ngakho-ke ukuze uqale ukuvikela ingxenye eseduze yejeneretha, gxuma usuke eswishi yengxenye eseduze.Isibonelo: ijeneretha enomugqa, i-generator ayigxumi, ibambezeleka ukweqa iswishi yomugqa.

A. Ukuvikelwa kwe-stator overcurrent okubangelwa ukujikeleza okufushane kwangaphandle.

b.Isivikelo sokulayishwa ngokweqile kwe-stator.

c.Ukujika kwe-rotor.

d, ukuvikelwa kokugcwala kwe-rotor.

e.Ukuvikelwa kwe-Stator winding overvoltage.

f.Ukuvikelwa kwamandla okuphambene.

g.Ukuvikela okungaphandle kwesinyathelo.

h.Ukuvikelwa kokuvusa amadlingozi.
i, ukuvikela imvamisa ephansi.

3. Ijeneretha,

eyasungulwa nguFaraday ngoSepthemba 23, 1831, iyinjini eguqula amandla emishini abe amandla kagesi.Ngokuvamile iqhutshwa yi-steam turbine, i-turbine yamanzi noma injini yomlilo yangaphakathi.Amandla kagesi angenye yemithombo yamandla ebaluleke kakhulu emphakathini wanamuhla.Amajeneretha asetshenziswa kakhulu ekukhiqizweni kwezimboni nezolimo, ukuvikela izwe, isayensi nobuchwepheshe kanye nempilo yansuku zonke.Amajeneretha ahlukaniswe abe amajeneretha e-DC kanye namajeneretha e-AC.Lesi sakamuva singahlukaniswa sibe yi-synchronous generator kanye ne-asynchronous generator izinhlobo ezimbili.Uhlobo oluvame kakhulu lwesiteshi sikagesi sesimanje ijeneretha ehambisanayo.
