Lus Cim: Cov khoom siv hluav taws xob qis qis tam sim no yog qhov kev xaiv hluav taws xob thaum muaj xwm txheej ceev rau cov neeg siv feem ntau, thiab cov qauv no feem ntau yog hais txog cov feem ntau siv 230V / 400V diesel generator teeb hauv khw.Txawm li cas los xij, hauv qee qhov chaw, vim qhov kev ncua deb ntawm chav tsev hluav taws xob diesel thiab cov chaw hluav taws xob, qhov hluav taws xob poob yuav tshwm sim, ua rau tsis muaj peev xwm siv hluav taws xob ib txwm muaj, thiab qhov xwm txheej hnyav, txawm tias cov khoom siv hluav taws xob hlawv.Yog li ntawd, rau cov neeg siv uas twb tau yuav lub tshuab hluav taws xob qis qis qis, kev ntsuas kev hloov kho los ntawm kev siv hluav taws xob qis mus rau qhov siab siab dhau los ua qhov kev xaiv zoo tshaj plaws, yog li tsis txhob cuam tshuam cov khoom siv hluav taws xob qis qis thiab ua rau poob nyiaj txiag loj.
1 、 Kev sib piv ntawm qhov zoo thiab qhov tsis zoo ntawm qhov siab thiab qis
1. Qhov zoo ntawm high-voltage generator teeb:
(1) Lub zog ntawm lub tshuab hluav taws xob tuaj yeem nce ntxiv, thiab lub zog siab tshaj plaws ntawm lub tshuab hluav taws xob high-voltage teeb tuaj yeem ncav cuag ntau txhiab, lossis txawm tias kaum txhiab kilowatts.Qhov no yog vim hais tias, thaum tso tawm tib lub hwj chim, tam sim no ntawm lub tshuab hluav taws xob high-voltage tuaj yeem me dua li ntawm lub tshuab hluav taws xob tsawg.Yog li high-voltage generator windings tuaj yeem siv cov kab me me.Yog li ntawd, lub stator tooj liab poob ntawm high-voltage generators tseem yuav me dua li ntawm cov hluav taws xob tsawg-voltage generators.Rau cov tshuab hluav taws xob siab, thaum siv hluav taws xob tsawg, qhov loj stator yuav tsum tau vim qhov xav tau ntawm cov xov hlau tuab, ua rau lub taub loj ntawm stator core thiab lub ntim loj ntawm tag nrho lub tshuab hluav taws xob;
(2) Rau cov tshuab hluav taws xob muaj peev xwm loj dua, cov tshuab hluav taws xob muaj hluav taws xob siv hluav taws xob tsawg thiab cov khoom siv hluav taws xob tsawg dua cov tshuab hluav taws xob tsawg, thiab muaj cov kab qis qis, uas tuaj yeem txuag tau qee qhov kev siv hluav taws xob.Tshwj xeeb tshaj yog rau 10KV high-voltage generators, lawv tuaj yeem siv ncaj qha rau hauv daim phiaj hluav taws xob, uas yuav txo qis peev hauv cov khoom siv hluav taws xob, yooj yim siv, thiab txo qhov tsis ua haujlwm.
2. Qhov tsis zoo ntawm cov khoom siv hluav taws xob hluav taws xob siab
(1) Tus nqi ntawm lub tshuab hluav taws xob windings yog qhov siab, thiab tus nqi ntawm cov khoom siv rwb thaiv tsev kuj tseem yuav nce ntxiv;
(2) Cov kev cai rau kev siv ib puag ncig ntawm cov tshuab hluav taws xob ntau dua li cov khoom siv hluav taws xob tsawg;
2, Boosting txoj kev rau generator poob lawm
Rau cov chaw uas xav tau cov khoom siv hluav taws xob siab, ntxiv rau kev faib rau cov khoom siv hluav taws xob siab, cov qauv hluav taws xob hluav taws xob teeb tsa nrog cov kauj ruam-up transformers kuj siv tau.
1. Qhov zoo ntawm Tsawg Voltage rau High Voltage Scheme
(1) Muaj ob lossis ntau qhov sib txawv ntawm qhov yuav tsum tau ua ntawm qhov chaw tsim kho, lossis qhov hluav taws xob tawm ntawm lub tshuab hluav taws xob yuav tsum tau hloov pauv;
(2) (Kev rho tawm kev hloov pauv kev cais tawm muaj nuj nqi) Lub siab-voltage kawg yog lub kaum sab xis transformer, thiab peb-theem peb xaim system tsis muaj xoom kab.Yog tsis muaj ib tug xoom kab, tsis muaj xoom kab hloov;Cais cov kev sib haum xeeb uas tsim los ntawm cov kab tsis muaj zog ntawm sab high-voltage los ntawm sab qis-voltage, ua rau sab qis-voltage huv si thiab tsis cuam tshuam rau kev ua haujlwm ntawm lub tshuab hluav taws xob tsis siv neeg voltage (AVR) hauv lub tshuab hluav taws xob teeb, nrog rau kev daws teeb meem. ntau yam teeb meem tshwm sim los ntawm xoom kab hloov chaw;
(3) Lub Great Inertia buffering muaj nuj nqi tshwj xeeb yog pab tau rau kev pib lub cev muaj zog loj.Lub peev xwm loj transformers muaj cov khoom siv tooj liab ntau dua, thiab cov tub ntxhais sib nqus loj ua lub luag haujlwm buffering, txo qhov cuam tshuam rau lub tshuab hluav taws xob thiab txhim kho qhov tam sim no voltage poob.
2. Qhov tsis zoo ntawm Parallel Connection Scheme rau Low Voltage Generator Units
Nyob rau hauv ib tug 380-415Vac generator teeb, yog hais tias ntau lub tshuab hluav taws xob teeb muaj kev cob cog rua nyob rau hauv parallel ntawm lub low-voltage sab thiab ces boosted los ntawm ib tug step-up transformer;Qhov kev pom zoo sab saud yog 7500 kVA, 6000 kW.Thaum tshaj qhov txwv, cov hauv qab no yuav tsum tau xav txog: -
Lub peev xwm ntawm qhov tsawg-voltage sab busbar yuav tsum nyob ze rau 10kA, coj mus rau hauv tus account lub busbar muaj peev xwm tiv taus qhov txhaum tam sim no thiab kev kho cua sov hauv qhov hloov hluav taws xob tsawg (kub nce ntawm qhov qis-voltage hloov screen);
• Lub peev xwm tripping ntawm low-voltage keyboards (txog mus rau qhov txhaum tam sim no), xws li mus txog 65kA thiab 100kA;
• Nws yog ib qho tsim nyog los xam seb qhov kev teeb tsa ntawm ze li ntawm 10000 ampere cables, cov hloov hluav taws xob tsawg, thiab cov nqi ntawm cov hluav taws xob tsawg yog qhov tsim nyog;
3 、 Cov ntaub ntawv kho dua tshiab
1. Cov khoom muaj pes tsawg leeg thiab cov tsis muaj
Tus neeg siv: Ib qhov project hauv Macau
