Ukonakala koomatshini kwiiJenereyitha zeDizili

Iseti yejeneretha esebenza ngokuchasene nombane ayinabungozi kwi ijenereyitha ngokwayo.Kodwa kukho izithintelo ezimbini:

1. Ngeli xesha, i-generator iba yi-motor, eya kuthatha amandla asebenzayo kwi-system ukuze kugcinwe ukusebenza kwe-synchronous, kwaye inkqubo yokuvuselela ayitshintshi;Nangona kunjalo, i-frequency yenkqubo inokuhla.Kwangaxeshanye amandla asebenzayo kwigridi, awayi kubangela ukuhla kwamandla ombane wenkqubo, aya kuba ngumsebenzi omfiliba kuphela.

2. Njenge-turbogenerator, ivalve engundoqo ye-injini yomoya ivaliwe xa ijika ibe yimeko yokusebenza engaqhelekanga yamandla abuyela umva, kwaye iblade yomsila weinjini yomoya ishushu kakhulu kwaye yonakaliswe ngenxa yokukhuhlana nomphunga oseleyo.Iingozi kwiiinjini zomphunga.Ngenxa yezi zizathu zibini zingentla, umonakalo kwi-injini yomphunga yeyona iphambili.Ke ngoko, iiyunithi ezinkulu kufuneka zixhotyiswe ngokhuseleko lwamandla angasemva.Olu khuselo lukhusela ikakhulu iiinjini zomphunga.

Ukumelana nokumelana nejenereyitha, kubandakanywa nestator insulation resistance measurement, rotor insulation resistance measure, ukuthwala i-insulation resistance measurement, izixhobo ezidityaniswe nejenereyitha kunye ne-exciter excitation loop, njl.

Indlela yokulinganisa yokumelana nokugquma kwejenereyitha

Isetyenziselwa ukujonga ukuba i-insulation ye-generator imanzi, ingcolile, umonakalo womatshini kunye nezinye iingxaki.

1. Umlinganiselo wokumelana ne-stator insulation.

I-wiring yokulinganisa iboniswe kwi-Figure 1. Kwiimoto ezilinganiswe ngaphezu kwe-volts ye-1000, sebenzisa i-2500 volt megohmmeter ukulinganisa ukuxhathisa kwe-insulation ye-15 kunye ne-60 imizuzwana kwaye ubale amazinga okufunxa.Ukuba i-insulation resistance resistance okanye izinga lokufunxa lincinci kakhulu, yongeza i-insulation resistance measurement yemizuzu eyi-10 ukubala i-polarization index.Kwi-epoxy mica powder insulation, izinga lokufunxa akufanele libe ngaphantsi kwe-1.6, isalathisi se-polarization akufanele sibe ngaphantsi kwe-1.6.

2.Ukulinganisa ukunyanzeliswa kwe-insulation ye-bearing housing.

Injongo yokulinganisa: Iibheringi ezikwicala le-exciter zihlala zikhutshiwe ukusuka emhlabeni ukuze zithintele umbane phakathi kombane we-shaft kunye nokuthwala ukutshisa i-bushing ngenxa ye-asymmetric flux ye-generator.

Ubume obuqhelekileyo be-insulation ye-turbogenerator buboniswe kwi-FIG.4. Xa uhlola ukugquma kwe-bearing, sebenzisa i-megohmmeter ye-1000V ukulinganisa ukunyanzeliswa kwe-insulation ye-gasket yensimbi emhlabeni.Ezinye i-turbogenerators zisebenzisa i-bushing insulation, i-bushing nganye ikhokelela kwindawo yokulinganisa, ngoko jonga ukunyanzeliswa kwe-insulation ye-bushing nganye.Ezinye ii-turbogenerators azinazo iindawo zokulinganisa i-bush kwaye zinokujongwa kuphela ngexesha lofakelo.

Ithrasti kunye neebheringi zesikhokelo ze-hydro-generator zineepads zokugquma phantsi kwethrust pad nganye.Ukuxhatshazwa kwe-insulation ye-bearing pad nganye kufuneka kuhlolwe ngexesha lofakelo.Ngaphambi kokuthwala i-oiling, ukunyanzeliswa kwe-insulation yesihlahla ngasinye esithwalayo akufanele kube ngaphantsi kwe-100 mω.

Xa i-insulation of bearing ingafanelekanga, ukongeza ekujongeni i-insulation pad, ingqwalasela kufuneka ihlawulwe ekukhangeleni ukuba i-insulation yamalungu adibaniswe ne-bearing, njengeqondo lokushisa, inzwa yokungcangcazela, umbhobho weoli, njl. .

I-Guangxi Dingbo Power Equipment Manufacturing Co., Ltd. esekwe ngo-2006, ngumvelisi wejenereyitha ye-diesel e-China, edibanisa ukuyila, ukubonelela, ukuthunyelwa kunye nokugcinwa kweseti yejeneretha ye-diesel.Imveliso igubungela iCummins, iPerkins, iVolvo, iYuchai, iShangchai, iDeutz, Ricardo , MTU, Weichai njl kunye noluhlu lwamandla 20kw-3000kw, kwaye babe yimveliso yabo ye-OEM kunye neziko lobuchwepheshe.
