Ukulimala Kwemishini Kumajeneretha Edizili

Isethi yejeneretha esebenza ngokumelene namandla ayilimazi ijeneretha uqobo.Kodwa kunezixwayiso ezimbili:

1. Ngalesi sikhathi, i-generator iba injini, ezothatha amandla asebenzayo ohlelweni ukuze kugcinwe ukusebenza okuhambisanayo, futhi uhlelo lokuvuselela alushintshi;Nokho, imvamisa yesistimu ingase yehle.Ngesikhathi esifanayo amandla asebenzayo kugridi, ngeke abangele ukwehla kwe-voltage yesistimu, azoba ukusebenza okuncane kuphela.

2. Njenge-turbogenerator, i-valve eyinhloko ye-turbine ivaliwe lapho iphenduka esimweni sokusebenza esingavamile samandla ahlehlayo, futhi i-blade yomsila we-turbine ishisa ngokweqile futhi yonakele ngenxa yokungqubuzana nomusi osele.Izingozi zama-steam turbines.Ngenxa yalezi zizathu ezimbili ezingenhla, ukulimala kwe-steam turbine yikona okuyinhloko.Ngakho-ke, amayunithi amakhulu kufanele afakwe ukuvikelwa kwamandla ahlehlayo.Lokhu kuvikela kuvikela ikakhulukazi izinjini zesitimu.

Ukumelana nokufakwa kwe-generator, okuhlanganisa isilinganiso sokumelana ne-stator insulation, ukulinganisa ukumelana nokufakwa kwe-rotor, isilinganiso sokumelana nokufakwa kwe-insulation, okokusebenza okuxhunywe ne-generator kanye ne-exciter excitation loop, njll.

Indlela yokulinganisa yokumelana nokufakwa kwejeneretha

Isetshenziselwa ukuhlola ukuthi ingabe i-generator insulation imanzi, ingcolile, ukulimala komshini nezinye izinkinga.

1. Isilinganiso sokumelana ne-stator insulation.

Izintambo zokulinganisa ziboniswa kuMfanekiso 1. Kumamotho anesilinganiso esiphakeme kuno-1000 volts, sebenzisa i-2500 volt megohmmeter ukuze ulinganise ukumelana nokufakwa kwe-insulation imizuzwana eyi-15 kanye ne-60 futhi ubale amazinga okumunca.Uma izinga lokumelana nokufakwa kwe-insulation noma izinga lokumunca lilincane kakhulu, engeza isilinganiso sokumelana nokufakwa kwe-insulation imizuzu eyi-10 ukuze ubale inkomba ye-polarization.Ukuze kufakwe i-epoxy mica powder insulation, izinga lokumunca akufanele libe ngaphansi kwe-1.6, inkomba ye-polarization akufanele ibe ngaphansi kwe-1.6.

2.Ukulinganisa ukumelana nokufakwa kwezindlu ezithwalayo.

Inhloso yokulinganisa: Ama-bearings asohlangothini lwe-exciter ngokuvamile afakwa ngaphansi ukuze avimbele amandla akhona phakathi kwe-voltage ye-shaft kanye ne-bearing ekushiseni i-bushing ngenxa yokuguquguquka kwe-asymmetric ye-generator.

Isakhiwo esijwayelekile sokufaka ukufakwa kwe-turbogenerator siboniswa ku-FIG.4. Uma uhlola ukufakwa kwe-bearing, sebenzisa i-megohmmeter engu-1000V ukuze ulinganise ukumelana nokushisa kwe-gasket yensimbi emhlabathini.Amanye ama-turbogenerator asebenzisa ukufakwa kwe-bushing, i-bushing ngayinye iholela endaweni yokulinganisa, ngakho-ke hlola ukumelana nokushisa kwe-bushing ngayinye.Amanye ama-turbogenerator awanawo amaphuzu okulinganisa amahlathi futhi angabhekwa kuphela ngesikhathi sokufakwa.

I-thrust kanye nama-guide bearings we-hydro-generator anamaphedi okufakwa ngaphansi kwe-thrust pad ngayinye.Ukumelana nokufakwa kwephedi ngalinye lokuthwala kufanele kubhekwe ngesikhathi sokufakwa.Ngaphambi kokuthela amafutha, ukumelana nokufakwa kwesihlahla ngasinye esithwalayo akufanele kube ngaphansi kuka-100 mω.

Lapho ukufakwa kwe-bearing kungafaneleki, ngaphezu kokuhlola i-insulation pad, kufanele futhi kukhokhwe ekuhloleni ukuthi ukufakwa kwezingxenye ezixhunywe ne-bearing, njengokushisa, inzwa yokudlidliza, ipayipi likawoyela, njll., kuyinto evamile. .

I-Guangxi Dingbo Power Equipment Manufacturing Co., Ltd. eyasungulwa ngo-2006, ingumkhiqizi wejeneretha kadizili eChina, ehlanganisa ukuklama, ukuhlinzeka, ukugunyazwa nokugcinwa kwesethi yejeneretha yedizili.Umkhiqizo uhlanganisa iCummins, Perkins, Volvo, Yuchai, Shangchai, Deutz, Ricardo , i-MTU, i-Weichai njll. enebanga lamandla angu-20kw-3000kw, futhi ibe yimboni yabo ye-OEM nesikhungo sobuchwepheshe.
