Jenareta Reverse Power Maintenance

Kuseta kuverenga kweiyo steam turbine inverse magetsi kugadzirisa ndeyekusimbisa simba rekushanda Pdz uye kunonoka kwekuita T kwekugadzirisa.

1. Simba rekuita rePdz set turbogenerator inverse simba rekugadzirisa simba rekuita rinogona kuverengerwa maererano neformula inotevera: Pdz=(Krel*P1)/η Pdz- inverse simba rekuchengetedza simba rekushanda simba Krel- reliability coefficient, tora 0.8 P1- simba rinoshandiswa. ne turbine kuchengetedza synchronous kutenderera kumhanya mushure mekunge vharafu huru yavharwa, ukuru hwesimba iri hune hukama nechimiro uye kugona kweiyo turbine, Izvo zvakare zvine chekuita nechimiro cheiyo main steam system ye turbogenerator (pipeline chimiro uye kunyangwe paine pombi yekunzvenga, nezvimwewo).Kazhinji, iyo yakarongerwa simba ndeye 1.5 ~ 2% η- simba rejenareta kana jenareta ichikwevera iyo turbogenerator kutenderera, uye 0.98 ~ 0.99, saka: Pdz≈ (1.2~1.6%) PN PN- iyo yakatarwa simba rejenareta. .Mukuita, Pdz = inogona kuva 1-1.5% PN.

2.Action kunonoka jenareta inverse simba rekugadzirisa chiito kunonoka, kunofanira kuenderana nemhepo turbine jenareta mushure mekunge vharafu huru yakavharwa inobvumirwa kushanda nguva yekuisa, nguva inobvumirwa inowanzo 10 ~ 15min.Iko kuverenga uye kuita kwekuita kunoratidza kuti kana iyo steam turbine steam system ine bypass pombi, nguva yekushanda inofanira kunge yakareba.Nokudaro, kana kunonoka kwechiito chekugadzirisa kwakagadzirirwa maererano nenguva yakabvumirwa kumhanya mushure mokunge vheji huru ye turbine yakavharwa, 5 ~ 10min inokurudzirwa.Mushure mekuita, inoshandiswa kubvisa magnetic field.

Pamusoro pezvo, iwo maturbogenerator makuru ari kushanda anonyanya kushandisa reverse magetsi kugadzirisa kutanga chirongwa cherwendo loop.Parizvino, nguva yekuita inowanzotora 1 ~ 2s.Kune chirongwa-inodzorwa inverse kuchengetedza simba, nekuti nguva yekushanda ipfupi, munguva pfupi pfupi mushure meiyo huru yevhavhavhavha yavharwa, nekuda kweiyo inertia ye turbine uye jenareta, iyo inoshanda inverse simba inogona kunge iri diki kwazvo, saka kukosha kwakatarwa kwesimba rinopesana haifanire kunge yakakura kupfuura 1% PN.

Nhanganyaya kumusimboti

Kana jenareta iine reverse simba (yekunze simba mapoinzi kune jenareta, kureva, jenareta inova mamiriro emota), reverse simba rekugadzirisa oparesheni redunhu breaker nzendo.Demand inounganidza matatu-phase voltage uye maviri-chikamu masaini masaini.

Nekuda kwemhando dzakasiyana dzesimba rekutanga, majenareta akasiyana anogona kugadzirwa.Kushandisa zviwanikwa zvemvura uye kushandira pamwe kwemvura turbine, inogona kugadzirwa mumvura turbine jenareta;Nekuda kwekusiyana kwesimba rekuchengetedza uye kudonha kwemusoro, ma hydro-jenareta ane huwandu hwakasiyana uye kumhanya anogona kugadzirwa.Uchishandisa marasha, mafuta uye zvimwe zviwanikwa uye kushandira pamwe nema boilers uye turbo-steam injini, turbo-jenareta anogona kugadzirwa, ayo anonyanya kumhanyisa mota (3000rpm).Pamusoro pezvo, kune marudzi ese emajenareta anoshandisa simba rezuva, simba remhepo, atomu simba, geothermal simba, tidal simba, biological simba zvichingodaro.Uye zvakare, nekuti iyo jenareta inoshanda musimboti yakasiyana uye yakakamurwa kuita dc jenareta, asynchronous jenareta uye synchronous jenareta.Mukushandiswa kwakapararira kwemajenareta makuru ari synchronous generator.

Guangxi Dingbo Power Equipment Manufacturing Co., Ltd. yakavambwa muna 2006, inogadzira dhiziri jenareta muChina, iyo inobatanidza dhizaini, kugovera, kutumira uye kugadzirisa dhiziri jenareta.Chigadzirwa chinofukidza Cummins, Perkins, Volvo , Yuchai, Shangchai, Deutz, Ricardo, MTU, Weichai etc. nesimba siyana 20kw-3000kw, uye kuva yavo OEM fekitari uye tekinoroji centre.
