Common Generator Faults Ntawm Detuz Generator

Los ntawm kev txheeb xyuas qhov ua tsis zoo ntawm cov tshuab hluav taws xob hauv thermal fais fab nroj tsuag, peb tuaj yeem paub cov yam ntxwv ntawm lub tshuab hluav taws xob tsis raug los ntawm kev sau cov kev cai ntawm lub tshuab hluav taws xob, thiab muab lub hauv paus thiab siv rau kev saib xyuas thiab teeb meem ntawm lub tshuab hluav taws xob.

Cov kev ua tsis tiav ntawm cov tshuab hluav taws xob yog raws li nram no:

(1) cov dej-txias stator windings, cov khoom tsim hluav taws xob hauv tsev thiab txawv teb chaws feem ntau siv hydrohydrogen txias hom.Dej-txias stator winding dej to yog ib qho txhaum.Cov xwm txheej hnyav feem ntau ua rau muaj kev sib tsoo hauv av thiab theem luv luv Circuit Court.Cov laj thawj tseem ceeb ntawm cov xwm txheej zoo li no yog tsim, txheej txheem thiab cov khoom siv.Lub ntsiab lus tseem ceeb ntawm kev kuaj xyuas cov pa tawm ntawm stator windings yuav tsum yog txoj kev ntsuas huab cua nruj (thawj sau cov cua compressed nrog nitrogen lossis freon siab ntawm 0.1 mpa, thiab thaum kawg ncav cuag qhov ntsuas siab, siv cov dej soapy lossis halogen leak detector txhawm rau txheeb xyuas qhov to. ).Thaum siv txoj kev airtight hauv thaj teb, cov dej hauv lub voj voog dej yuav tsum tau muab tshem tawm thiab qhuav ua ntej qhov kev sim kom tshem tawm cov dej tsis ruaj.

(2) dej-txias stator thiab rotor winding blockage kuj yog ib qho txhaum cai.Qhov laj thawj tseem ceeb ntawm kev ua tsis tiav yog tias cov dej txias txias tsis yog raws li tus qauv, tsim los ntawm precipitated oxide blockage, los yog muaj cov khoom txawv teb chaws (rubber pad, asbestos av nkos los yog rags).Nyob hauv lub voj voog dej.Qhov kev ntsuas tseem ceeb txhawm rau tshem tawm cov kev thaiv lub cev txawv teb chaws yog tswj hwm lub cev muaj zog sib dhos thiab kev saib xyuas cov txheej txheem thiab cov kev tshuaj xyuas zoo sib xws.Tsis tas li ntawd, kev kuaj rov qab thiab dej ntws yuav tsum tau ua raws li cov qauv thiab cov txheej txheem.

(3) Theem luv Circuit Court tshwm sim los ntawm qhov kawg coil tsis ua haujlwm.Cov laj thawj tseem ceeb ntawm kev sib tsoo luv luv yog qhov tsim tsis tsim nyog ntawm qhov kawg ruaj ruaj, txheej txheem rwb thaiv tsev tsis zoo, cov txheej txheem vuam tsis zoo.

tooj liab hlau, tsis tsim nyog xaiv cov khoom siv thiab tshuaj xyuas, thiab lwm yam. Cov av noo siab ntawm hydrogen hauv cov tshuab, uas tsis yog raws li tus qauv, feem ntau yog qhov ua rau muaj xwm txheej.

(4) luv luv Circuit Court thiab grounding txhaum ntawm lem ntawm rotor windings yog ib qho txhaum cai, uas yog tshwm sim los ntawm thermal deformation los yog siab kub khiav hauj lwm ntawm rotor windings, uas ua rau rwb thaiv tsev puas ntawm lem.Cov kev cai ntawm lub tshuab hluav taws xob ua haujlwm tau tshaj tawm los ntawm Ministry of Electric Power tau teev tseg tias thaum lub rotor winding ntawm lub tshuab hluav taws xob zais zais yog grounded ntawm ib qho chaw, qhov chaw thiab qhov xwm txheej ntawm qhov txhaum yuav tsum raug pom tam sim ntawd.Yog tias nws yog qhov ruaj khov hlau hauv av, lub tshuab hluav taws xob rotor-txias nrog lub peev xwm ntawm 100 MW lossis ntau dua yuav tsum raug kaw kom sai li sai tau.Rau cov tshuab hluav taws xob qis dua 100MW, ob lub ntsiab lus hauv av tiv thaiv yuav tsum tau txuas nrog lub zog hluav taws xob, thiab sai li sai tau los npaj kev kaw haujlwm.

(5) Axial voltage ntawm turbogenerator teeb;Lub axial voltage feem ntau yog tshwm sim los ntawm tus nqi zoo li qub ntawm lub tog raj kheej tsis tshua muaj siab ntawm lub turbine.Sib nqus Circuit Court asymmetry thaum lub tshuab hluav taws xob tsim khoom lossis ua haujlwm;Lub pulsation tivthaiv ntawm static excitation system;Monopole tej zaum tshwm sim los ntawm luv luv Circuit Court ntawm lem ntawm rotor winding.

Guangxi Dingbo Fais fab Equipment Manufacturing Co., Ltd. tsim nyob rau hauv 2006, yog ib lub chaw tsim tshuaj paus ntawm diesel generator nyob rau hauv Tuam Tshoj, uas integrates tsim, muab, commissioning thiab txij nkawm ntawm diesel generator teeb.Cov khoom lag luam npog Cummins, Perkins, Volvo, Yuchai, Shangchai, Deutz, Ricardo, MTU, Weichai thiab lwm yam nrog lub hwj chim ntau 20kw-3000kw, thiab dhau los ua lawv lub Hoobkas OEM thiab chaw siv tshuab.
