Hom hluav taws xob thaum muaj xwm ceev
Oct 18, 2022
Thaum cov tsev lag luam thiab pej xeem nyob rau hauv lub xeev hluav taws kub ceev, txhawm rau ua kom muaj kev sib ntaus sib tua hluav taws zoo, cov khoom siv hluav taws xob ywj pheej uas yog lub luag haujlwm rau kev muab cov khoom siv hluav taws xob hluav taws xob hu ua hluav taws xob thaum muaj xwm ceev. Txoj Cai rau Kev Tsim Hluav Taws Xob ntawm Civil Buildings qhia meej meej tias thawj theem load yuav tsum tau siv los ntawm ob lub zog siv hluav taws xob. Thaum ib lub hwj chim tsis ua hauj lwm, lwm lub hwj chim yuav tsis raug puas tsuaj; Cov ntaub ntawv fais fab ntawm thawj theem load muaj xws li ob qhov khoom siv hluav taws xob high-voltage, ib qho hluav taws xob high-voltage thiab ib qho hluav taws xob qis qis, lub tshuab hluav taws xob diesel teeb lossis roj teeb pob; Ntxiv rau cov khoom siv hluav taws xob saum toj no, cov khoom siv hluav taws xob thaum muaj xwm ceev yuav tsum tau ntxiv rau qhov tshwj xeeb tseem ceeb ntawm cov khoom thauj khoom hauv thawj theem.
Hom kev siv hluav taws xob thaum muaj xwm ceev
1. EPS hluav taws xob thaum muaj xwm txheej ceev: Nws yog ib qho khoom siv hluav taws xob thaum muaj xwm txheej ceev uas muaj xws li charger, inverter, cia roj teeb, cais transformer, hloov pauv hloov thiab lwm yam khoom siv uas thim rov qab DC fais fab rau hauv AC zog. Nws muaj feem xyuam rau lub thauj khoom nrog lub sijhawm tso cai cuam tshuam ntau dua 0.25s.
2. UPS: Nws yog ib qho khoom siv hluav taws xob zoo li qub AC uninterruptible fais fab mov uas tsim los ntawm lub zog hloov hluav taws xob lub zog cia khoom (roj teeb) thiab hloov pauv (hluav taws xob thiab khoom siv hluav taws xob) kom ntseeg tau lub zog txuas ntxiv. Nws muaj feem xyuam rau lub load nrog lub sijhawm cuam tshuam millisecond.
3. Self muab thaum muaj xwm ceev diesel generator teeb: nws yog ib lub zog tsim khoom tsim los ntawm diesel cav uas tau tsav lub hwj chim zaus AC synchronous generator. Lub tshuab hluav taws xob pib ceev nws tus kheej yog siv tau rau cov tsev uas muaj lub zog cuam tshuam lub sijhawm ntau dua 15s. Lub sijhawm ua haujlwm ntawm cov khoom siv hluav taws xob thaum muaj xwm txheej ceev yuav tsum raug txiav txim siab raws li lub sijhawm siv hluav taws xob tsis ua haujlwm tau tso cai hauv kev tsim khoom siv tshuab. Thaum nws siv nrog rau qhov pib lub tshuab hluav taws xob pib, nws yuav tsum tsis pub tsawg dua 10min.
4. Tshwj xeeb feeder kab nrog tsis siv neeg switching ntaus ntawv ywj siab ntawm ib txwm fais fab mov. Lub sijhawm ua haujlwm muaj feem xyuam rau cov cuab yeej hloov pauv tsis siv neeg tuaj yeem ua tau raws li cov khoom siv hluav taws xob thaum muaj xwm txheej ceev nrog lub sijhawm cuam tshuam ntawm 1.5 s lossis ntau dua. Yog tias DC fais fab mov tuaj yeem siv tau rau cov khoom tseem ceeb tshwj xeeb nrog lub millisecond fais fab tuag thiab muaj peev xwm me me, cov roj teeb pob yuav tsum tau siv los ua hluav taws xob thaum muaj xwm ceev.
5. Tus kheej muab cov roj turbine generator thaum muaj xwm ceev; Nws yog cov cuab yeej tsim hluav taws xob uas tau tsav los ntawm cov roj turbine thiab tsav los ntawm lub zog zaus AC synchronous generator.
