Generator Reverse Power Maintenance

Kev teeb tsa kev suav ntawm chav turbine thim rov qab kev saib xyuas lub zog yog kom paub meej tias lub zog ua haujlwm Pdz thiab kev txiav txim ncua T ntawm kev saib xyuas.

1. Kev ua haujlwm fais fab ntawm Pdz teeb turbogenerator inverse hwj chim txij nkawm kev txiav txim fais fab tuaj yeem xam raws li cov qauv hauv qab no: Pdz = (Krel * P1) / η Pdz- thim rov qab kev tswj fais fab kev lag luam fais fab Krel- kev ntseeg siab coefficient, noj 0.8 P1- lub zog noj los ntawm lub turbine kom tswj tau synchronous kev sib hloov ceev tom qab lub ntsiab valve raug kaw, qhov loj ntawm lub hwj chim no muaj feem xyuam rau cov qauv thiab lub peev xwm ntawm lub turbine, Nws kuj muaj feem xyuam rau cov qauv ntawm lub ntsiab chav system ntawm lub turbogenerator (pipeline qauv thiab seb puas muaj bypass pipeline, thiab lwm yam).Feem ntau, lub zog ntsuas yog 1.5 ~ 2% η - lub zog ntawm lub tshuab hluav taws xob thaum lub tshuab hluav taws xob rub lub tshuab hluav taws xob tig, thiab 0.98 ~ 0.99, yog li: Pdz≈ (1.2 ~ 1.6%) PN PN- lub zog ntsuas ntawm lub tshuab hluav taws xob .Hauv kev xyaum, Pdz = tuaj yeem yog 1-1.5% PN.

2. Kev ua haujlwm qeeb lub tshuab hluav taws xob thim rov qab lub hwj chim txij nkawm ncua sijhawm, yuav tsum ua raws li lub tshuab hluav taws xob lub tshuab hluav taws xob tom qab lub ntsiab valve kaw tso cai rau lub sijhawm ua haujlwm, lub sijhawm tso cai feem ntau yog 10 ~ 15min.Kev suav thiab kev xyaum ua haujlwm qhia tau hais tias thaum lub tshuab ua haujlwm turbine chav muaj bypass yeeb nkab, lub sijhawm ua haujlwm yuav tsum ntev dua.Yog li, yog tias qhov kev saib xyuas ncua sij hawm tau teem caij raws li lub sijhawm tso cai khiav tom qab lub ntsiab chav turbine valve raug kaw, 5 ~ 10min yog qhov pom zoo.Tom qab kev txiav txim, nws yog siv rau disengage magnetic teb.

Tsis tas li ntawd, cov turbogenerators loj hauv kev ua haujlwm feem ntau siv rov qab siv hluav taws xob los pib qhov kev pab cuam mus ncig.Tam sim no, lub sijhawm ua haujlwm feem ntau siv 1 ~ 2s.Rau kev tswj hwm kev tswj xyuas hluav taws xob thim rov qab, vim tias lub sijhawm ua haujlwm luv luv, nyob rau lub sijhawm luv luv tom qab lub ntsiab chav valve tau kaw, vim qhov inertia ntawm lub turbine thiab lub tshuab hluav taws xob, qhov kev siv zog rov qab tuaj yeem tsawg heev, yog li cov khoom siv hluav taws xob tsis zoo. Tus nqi ruaj khov ntawm lub zog hloov pauv yuav tsum tsis txhob siab dua 1% PN.

Kev taw qhia txog lub hauv paus ntsiab lus

Thaum lub tshuab hluav taws xob muaj hluav taws xob rov qab (sab nraud lub zog taw qhia rau lub tshuab hluav taws xob, uas yog, lub tshuab hluav taws xob dhau los ua lub cev muaj zog), lub zog rov qab tswj xyuas kev ua haujlwm Circuit Court breaker mus ncig.Kev thov sau peb-theem voltage thiab ob-theem tam sim no cov cim.

Vim yog cov qauv sib txawv ntawm lub zog tseem ceeb, cov tshuab hluav taws xob sib txawv tuaj yeem ua tau.Siv cov khoom siv dej thiab dej turbine kev koom tes, tuaj yeem ua rau lub tshuab hluav taws xob dej turbine;Vim tias qhov sib txawv ntawm lub peev xwm ntawm lub reservoir thiab lub taub hau poob, hydro-generators muaj peev xwm sib txawv thiab ceev tuaj yeem ua.Siv cov thee, roj thiab lwm yam kev pab cuam thiab kev koom tes nrog boilers thiab turbo-steam xyaw, turbo-generators tuaj yeem ua tau, uas feem ntau yog cov motors siab ceev (3000rpm).Tsis tas li ntawd, muaj txhua yam ntawm cov tshuab hluav taws xob siv lub hnub ci, lub zog cua, lub zog atomic, lub zog hluav taws xob, lub zog tidal, lub zog roj ntsha thiab lwm yam.Tsis tas li ntawd, vim hais tias lub tshuab hluav taws xob ua haujlwm txoj cai sib txawv thiab muab faib ua dc generator, asynchronous generator thiab synchronous generator.Nyob rau hauv dav siv ntawm loj generators yog synchronous generators.

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