Lub tshuab hluav taws xob thiab lub cev muaj zog yog lub npe hu ua ob hom khoom siv tshuab.Ib qho yog hloov lwm lub zog rau hauv lub zog hluav taws xob rau lub zog tsim hluav taws xob, thaum lub cev muaj zog hloov hluav taws xob rau hauv lub zog siv hluav taws xob kom rub lwm yam khoom.Txawm li cas los xij, ob qho tib si tsis tuaj yeem nruab thiab hloov nrog ib leeg.Qee hom tshuab hluav taws xob thiab lub cev muaj zog tuaj yeem hloov pauv tom qab tsim thiab hloov kho.Txawm li cas los xij, yog tias muaj kev txhaum, lub tshuab hluav taws xob kuj tau hloov mus rau kev ua haujlwm ntawm lub cev muaj zog, uas yog kev tiv thaiv rov qab los ntawm lub zog rov qab ntawm lub tshuab hluav taws xob peb xav tham txog hnub no.
Lub zog rov qab yog dab tsi?
Raws li peb txhua tus paub, lub zog kev taw qhia ntawm lub tshuab hluav taws xob yuav tsum ntws los ntawm lub tshuab hluav taws xob kev taw qhia mus rau qhov system kev taw qhia.Txawm li cas los xij, rau qee qhov laj thawj, thaum lub tshuab hluav taws xob poob lub zog thiab lub tshuab hluav taws xob hluav taws xob hloov pauv tsis mus, lub zog kev taw qhia hloov ntawm lub cev mus rau lub tshuab hluav taws xob, uas yog, lub tshuab hluav taws xob hloov mus rau lub cev muaj zog hauv kev ua haujlwm.Lub sijhawm no, lub tshuab hluav taws xob absorbs lub zog ua haujlwm ntawm lub cev, uas yog hu ua rov qab fais fab.
Kev puas tsuaj ntawm lub zog rov qab
Lub tshuab hluav taws xob rov qab tiv thaiv hluav taws xob yog tias thaum lub ntsiab throttle valve ntawm chav turbine raug kaw vim qee qhov laj thawj thiab lub zog qub ploj, lub tshuab hluav taws xob hloov mus rau hauv lub cev muaj zog los tsav lub chav turbine tig.Kev sib hloov ceev ceev ntawm chav turbine hniav yam tsis muaj chav yuav ua rau tawg kev sib txhuam, tshwj xeeb tshaj yog nyob rau theem kawg hniav, nws yuav ua rau overheating thiab ua rau muaj kev puas tsuaj ntawm lub rotor hniav.
Yog li ntawd, kev tiv thaiv hluav taws xob rov qab yog qhov kev tiv thaiv ntawm chav turbine yam tsis muaj chav ua haujlwm.
Programmed rov qab fais fab kev tiv thaiv ntawm generator
Lub tshuab hluav taws xob qhov kev tiv thaiv hluav taws xob thim rov qab yog qhov tseem ceeb los tiv thaiv lub tshuab hluav taws xob los ntawm dheev tripping lub tshuab hluav taws xob qhov hluav taws xob hloov nyob rau hauv ib qho kev thauj khoom thiab lub ntsiab throttle valve ntawm chav turbine tsis kaw tag nrho.Nyob rau hauv cov ntaub ntawv no, chav turbine generator yog nquag mus overspeed thiab txawm speeding.Txhawm rau zam qhov xwm txheej no, rau qee qhov kev tiv thaiv yam tsis muaj kev cuam tshuam luv luv, tom qab xa cov teeb liab ua haujlwm, nws yuav xub ua rau kaw lub ntsiab chav valve ntawm chav turbine.Tom qab lub zog rov qab * * * ntawm lub tshuab hluav taws xob ua haujlwm, nws yuav tsim thiab valve nrog lub teeb liab kaw lub ntsiab chav valve, daim ntawv thov rov qab lub zog tiv thaiv tom qab lub sijhawm luv luv, thiab qhov kev txiav txim yuav ua tiav tag nrho.
Qhov sib txawv ntawm kev tiv thaiv hluav taws xob rov qab thiab kev tiv thaiv hluav taws xob rov qab
Kev tiv thaiv hluav taws xob rov qab yog txhawm rau tiv thaiv lub tshuab hluav taws xob los ntawm kev tig mus rau hauv lub cev muaj zog tom qab rov qab lub zog, tsav lub zog turbine tig thiab ua rau muaj kev puas tsuaj rau lub tshuab hluav taws xob.Nyob rau hauv qhov kev ntsuam xyuas zaum kawg, kuv ntshai tias tus thawj tswj hwm yuav raug tsav los ntawm lub kaw lus yog tias nws tsis muaj hwj chim!
Qhov kev pab cuam rov qab fais fab kev tiv thaiv yog los tiv thaiv lub turbine overspeed los ntawm lub ntsiab throttle valve tsis tag nrho kaw tom qab lub tshuab hluav taws xob chav tsev yog dheev disconnected, yog li ntawd lub hwj chim rov qab yog siv kom tsis txhob.Nyob rau hauv qhov kev ntsuam xyuas zaum kawg, kuv ntshai tias ntau dhau lub zog ntawm tus thawj txav yuav ua rau overspeed ntawm chav tsev.
Yog li ntawd, nruj me ntsis hais lus, thim rov qab lub hwj chim tiv thaiv yog ib hom generator relay tiv thaiv, tab sis nws tsuas yog tiv thaiv chav turbine.Qhov kev pab cuam thim rov qab kev tiv thaiv hluav taws xob tsis yog kev tiv thaiv, tab sis txheej txheem kev nqis tes ua kom paub txog qhov program tripping, tseem hu ua program tripping, uas feem ntau siv rau kev kaw hom.
Qhov tseem ceeb yog tias ntev npaum li lub hwj chim rov qab mus txog qhov teeb tsa, nws yuav mus.Ntxiv nrog rau kev ncav cuag tus nqi, qhov kev pab cuam rov qab fais fab tseem yuav tsum tau kaw lub ntsiab valve ntawm chav turbine kom raug kaw.Yog li ntawd, qhov rov qab fais fab yuav tsum tau zam thaum lub sij hawm ntawm daim phiaj sib txuas thaum lub sij hawm pib chav tsev.
Cov no yog cov haujlwm ntawm lub tshuab hluav taws xob rov qab tiv thaiv thiab kev piav qhia ntawm lub tshuab hluav taws xob rov qab fais fab.Rau cov chav turbine generator nyob rau hauv daim phiaj kev sib txuas ua haujlwm, nws yuav ua haujlwm raws li lub cev muaj zog synchronous tom qab lub ntsiab throttle valve ntawm chav turbine raug kaw: nqus lub zog nquag thiab rub lub chav turbine tig, uas tuaj yeem xa rov qab lub zog rau lub zog.Raws li lub ntsiab throttle valve ntawm chav turbine tau raug kaw, tus Tsov tus tw hniav ntawm chav turbine muaj kev sib txhuam nrog cov seem seem los ua blast poob, uas yog puas los ntawm overheating thaum lub sij hawm ua hauj lwm mus sij hawm ntev.Nyob rau lub sijhawm no, kev tiv thaiv rov qab tuaj yeem tiv thaiv lub tshuab hluav taws xob los ntawm kev puas tsuaj.
