Reverse Mphamvu Yamagetsi a Dizilo

Pamene jenereta ali ndi n'zosiyana mphamvu (kunja mphamvu malo kwa jenereta, mwachitsanzo jenereta amakhala galimoto), n'zosiyana mphamvu amateteza kanthu dera wosweka kuti asagwe.Magetsi a magawo atatu ndi ma sign apano a magawo awiri ayenera kusonkhanitsidwa.

Chifukwa cha mitundu yosiyanasiyana ya mphamvu zoyambira, ma jenereta osiyanasiyana amatha kupangidwa.Ma hydrogenerator amatha kupangidwa kuchokera kumadzi ndi ma turbines.Chifukwa cha mphamvu zosiyanasiyana zosungiramo madzi ndi dontho, ma hydro-generator okhala ndi mphamvu zosiyanasiyana komanso liwiro amatha kupangidwa.Pogwiritsa ntchito malasha, mafuta ndi zinthu zina, ndi ma boilers ndi ma injini a turbo-steam, ma jenereta opangira nthunzi amatha kupangidwa, makamaka ma mota othamanga kwambiri (3000rpm).Palinso ma jenereta omwe amagwiritsa ntchito solar, mphepo, atomiki, geothermal, tidal ndi bioenergy.Kuphatikiza apo, chifukwa cha mfundo zosiyanasiyana zogwirira ntchito za ma jenereta, amagawidwa kukhala majenereta a DC, majenereta asynchronous ndi majenereta ofananira.Majenereta akuluakulu omwe amagwiritsidwa ntchito kwambiri ndi majenereta a synchronous.

Wopanga ma jenereta 's reverse mphamvu

Monga tonse tikudziwira, mphamvu yamagetsi ya jenereta iyenera kuyenda kuchokera kumbali ya jenereta kupita ku dongosolo.Koma pazifukwa zina, pamene turbine wataya mphamvu ndi chosinthira jenereta kubwereketsa sikuyenda, malangizo mphamvu kusintha kuchokera dongosolo kwa jenereta, ndiko kuti, jenereta amakhala galimoto ntchito.Panthawiyi jenereta imakoka mphamvu yogwira ntchito kuchokera ku dongosolo, lotchedwa inverse power.

01. Zowopsa zamagetsi am'mbuyo.

Kutetezedwa kwa mphamvu ya jenereta kumatanthawuza kuti pamene turbine itaya mphamvu chifukwa cha kutseka kwa valve yaikulu pazifukwa zina, jeneretayo imasandulika kukhala injini yoyendetsa turbine kuti izungulire.Tsamba la turbine limayenda mothamanga kwambiri popanda nthunzi, zomwe zingayambitse mikangano yophulika, makamaka tsamba lomaliza, lomwe lingayambitse kutentha kwambiri ndikuwononga tsamba la rotor.Chifukwa chake chitetezo cham'mbuyo ndicho chitetezo cha turbine popanda kuthamanga.

02.Jenereta reverse mphamvu chitetezo pulogalamu.

Dongosolo la jenereta lachitetezo champhamvu kwambiri limateteza jenereta kuti lisatsegule mwadzidzidzi chosinthira chamagetsi, ndipo mavavu onse akulu a turbine sangathe kutsekedwa ndi katundu wina.Pankhaniyi, turbine jenereta akonzedwa sachedwa overspeed kapena ngakhale kulamulira.Kuti mupewe izi, pachitetezo china chosafupikitsa, choyamba chimatseka valavu yayikulu ya turbine pambuyo potumiza chizindikiro.Pambuyo pa jenereta yodutsa mphamvu yowonjezera mphamvu, chizindikiro cha kutseka valavu yaikulu chimapangidwa ndipo chipata chimapangidwa.Pakapita nthawi yochepa, chitetezo chamagetsi chimapangidwa ndipo ntchitoyi imayimitsidwa.

03.Reverse chitetezo mphamvu ndi pulogalamu reverse chitetezo mphamvu kusiyana.

Reverse mphamvu chitetezo ndi kuteteza jenereta kuchokera kumagetsi obwerera m'mbuyo kupita ku injini, kuyendetsa kasinthasintha wa turbine, zomwe zimapangitsa kuwonongeka kwa turbine.Pambuyo pake, ndikuwopa kuti woyendetsa wamkulu adzathamanga ndi dongosolo chifukwa cha kusowa mphamvu! Chitetezo chamagetsi chosinthika chakonzedwa kuti chiteteze turbine kuchokera ku overspeed pambuyo poti jenereta imachotsedwa mwadzidzidzi ndipo valavu yaikulu yatsekedwa kwathunthu, yomwe imatha. kupewedwa pogwiritsa ntchito mphamvu yakumbuyo.Chofunikira ndichakuti woyendetsa wamkuluyo ndi wamphamvu kwambiri kuti apangitse kuti gawolo liwonjezeke!

Kunena mosamalitsa, chitetezo chosinthira mphamvu ndi chitetezo cha jenereta, koma makamaka kuteteza turbine.Kutetezedwa kwamphamvu kwa pulogalamu sichitetezo, koma ndi njira yokhazikitsidwa kuti mukwaniritse ulendo wa pulogalamu, womwe umadziwikanso kuti ulendo wa pulogalamu, womwe umagwiritsidwa ntchito potseka.
