Rov qab Fais Fab Ntawm Diesel Generators

Thaum lub tshuab hluav taws xob muaj hluav taws xob rov qab (qhov hluav taws xob sab nraud taw qhia rau lub tshuab hluav taws xob, piv txwv li lub tshuab hluav taws xob dhau los ua lub cev muaj zog), lub zog rov qab tiv thaiv qhov kev txiav txim hluav taws xob los ntawm tripping.Peb theem voltage thiab ob theem tam sim no teeb liab yuav tsum tau sau.

Vim yog cov qauv sib txawv ntawm lub zog tseem ceeb, cov tshuab hluav taws xob sib txawv tuaj yeem ua tau.Hydrogenerators tuaj yeem tsim los ntawm dej thiab turbines.Vim muaj peev xwm sib txawv ntawm cov reservoir thiab poob, hydro-generators nrog lub peev xwm sib txawv thiab ceev tuaj yeem tsim.Siv cov thee, roj thiab lwm yam kev pab, nrog rau cov boilers thiab turbo-steam xyaw, chav turbine generators yuav ua tau, feem ntau high-ceev motors (3000rpm).Kuj tseem muaj cov tshuab hluav taws xob uas siv hnub ci, cua, atomic, geothermal, tidal thiab bioenergy.Tsis tas li ntawd, vim yog cov qauv kev ua haujlwm sib txawv ntawm cov tshuab hluav taws xob, lawv tau muab faib ua DC generators, asynchronous generators thiab synchronous generators.Cov generators loj siv dav yog synchronous generators.

Generator Chaw tsim tshuaj paus lub zog rov qab

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.Tab sis rau qee qhov laj thawj, thaum lub turbine poob lub zog thiab lub tshuab hluav taws xob qhov hluav taws xob hloov tsis mus, cov kev taw qhia ntawm lub zog hloov ntawm lub cev mus rau lub tshuab hluav taws xob, uas yog, lub tshuab hluav taws xob ua lub cev muaj zog hauv kev ua haujlwm.Lub sijhawm no lub tshuab hluav taws xob rub tawm lub zog los ntawm qhov system, hu ua inverse power.

01. Kev puas tsuaj ntawm qhov rov qab fais fab mov.

Generator inverse power tiv thaiv hais txog tias thaum lub turbine poob lub zog vim lub ntsiab valve kaw rau qee yam, lub tshuab hluav taws xob hloov mus rau hauv lub cev muaj zog tsav lub turbine tig.Lub turbine hniav tig ntawm qhov kub ceev yam tsis muaj chav, uas yuav ua rau tawg kev sib txhuam, tshwj xeeb tshaj yog cov hniav theem kawg, uas yuav ua rau overheating thiab puas rotor hniav.Yog li kev tiv thaiv hluav taws xob rov qab yog qhov kev tiv thaiv ntawm lub turbine yam tsis tau khiav.

02.Generator thim rov qab lub zog tiv thaiv kev pab cuam.

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 kev qhib lub qhov hluav taws xob tam sim ntawd, thiab tag nrho cov valve tseem ceeb ntawm lub turbine tsis tuaj yeem raug kaw nyob rau hauv ib qho kev thauj khoom.Nyob rau hauv cov ntaub ntawv no, lub turbine generator teeb yog nquag mus overspeed los yog txawm tawm ntawm kev tswj.Txhawm rau zam qhov no, rau qee qhov kev tiv thaiv tsis raug luv luv, nws thawj zaug kaw lub ntsiab valve ntawm lub turbine tom qab xa tawm cov teeb liab ua haujlwm.Tom qab lub tshuab hluav taws xob hloov hluav taws xob rov qab ua haujlwm, lub teeb liab ntawm kev kaw lub ntsiab valve yog tsim thiab lub rooj vag tsim.Tom qab ib lub sij hawm luv luv, qhov kev zov me nyuam rov tiv thaiv hluav taws xob yog tsim thiab kev ua haujlwm tau nres tag nrho.

03.Kev tiv thaiv hluav taws xob rov qab thiab qhov kev pab cuam rov qab lub zog tiv thaiv qhov sib txawv.

Rov qab fais fab kev tiv thaiv yog los tiv thaiv cov lub tshuab hluav taws xob los ntawm thim rov qab lub zog mus rau hauv lub cev muaj zog, tsav lub turbine tig, ua rau turbine puas.Tom qab tag nrho, kuv ntshai tus thawj mover yuav khiav nrog lub system vim tsis muaj hwj chim! Programmed rov qab hwj chim tiv thaiv yog tsim los tiv thaiv lub turbine los ntawm overspeed tom qab lub generator teeb yog dheev disconnected thiab lub ntsiab valve yog kiag li kaw, uas muaj peev xwm. zam los ntawm kev siv lub zog rov qab.Cov kab hauv qab yog tias tus thawj txav tseem muaj zog dhau los ua rau lub tsev mus dhau nrawm!

Yog li nruj me ntsis hais lus, kev tiv thaiv hluav taws xob rov qab yog kev tiv thaiv relay ntawm lub tshuab hluav taws xob, tab sis feem ntau yog los tiv thaiv lub turbine.Kev tiv thaiv hluav taws xob thim rov qab tsis yog kev tiv thaiv, tab sis cov txheej txheem ua haujlwm tau teeb tsa kom ua tiav qhov kev mus ncig, tseem hu ua kev mus ncig, feem ntau siv rau hauv hom kaw.
