Cov chaw hluav taws xob tsis tuaj yeem ntseeg tau thiab qee zaum kaw, uas ua rau muaj kev cuam tshuam tsis zoo rau cov neeg siv khoom. Qhov no tsis tsim nyog rau cov khoom siv tseem ceeb, yog li lawv tau siv los ntawm ob lossis ntau qhov chaw ntxiv. Thaum lawv txuas nrog, ATS cov cuab yeej siv. Nws yog dab tsi, piav qhia txog kev txiav txim siab ntawm cov ntawv luv - "automatic input of the reserve." Nws yog ib txoj hauv kev los tsim kom muaj lub zog tsis cuam tshuam rau cov neeg siv khoom nrog ob lossis ntau lub zog nkag. Qhov no tau lees paub los ntawm kev sib txuas tsis siv neeg ntawm cov ntaub ntawv thaub qab thaum poob ntawm qhov tseem ceeb.
Ob lub zog siv hluav taws xob tuaj yeem txuas rau tib lub sijhawm. Qhov tsis zoo ntawm txoj kev no yog qhov luv luv Circuit Court tam sim no, siab poob thiab nyuaj ntawm kev tiv thaiv network. Cov tswv yim ntawm qhov cia yog feem ntau yog ua los ntawm kev siv lub tshuab hloov pauv uas tig tawm lub zog loj. Lub zog cia yuav tsum sib haum nrog cov loads. Yog tias tsis txaus, tsuas yog cov neeg siv khoom tseem ceeb tshaj plaws tau txuas nrog.
ATS cov tseev kom muaj
- Kev hloov pauv ceev ceev tom qab ua haujlwm relayvoltage.
- Tig rau txhua qhov xwm txheej thaum lub zog tsis ua haujlwm, tshwj tsis yog cov luv luv.
- Tsis teb rau qhov poob qis thaum pib muaj zog ntawm cov neeg siv khoom.
- Kev ua ib leeg.
Kev faib tawm
Cov khoom siv tau muab faib ua raws li txoj cai ntawm kev ua haujlwm.
- ib leeg ib sab. Cov txheej txheem muaj ob ntu: cov khoom siv hluav taws xob thiab khaws cia. Cov tom kawg txuas nrog thaum lub ntsiab voltage poob.
- ob sab. Ib qho ntawm cov kab tuaj yeem ua haujlwm thiab khaws cia.
- Rov qab ATS. Thaum lub zog tseem ceeb rov qab los, lub voj voog yav dhau los tau muab tso rau hauv kev ua haujlwm, thiab lub voj voog thaub qab raug kaw.
- Tsis siv neeg rov qab. Kev ua haujlwm hom nrog lub ntsiab fais fab mov yog teem manually.
ATS txoj cai ua haujlwm
Hauv cov tes hauj lwm uas tsis muaj hluav taws xob, nws yooj yim siv cov relay tshwj xeeb uas tswj qhov hluav taws xob hauv kev tiv thaiv circuits (ATS circuits, thiab lwm yam). ATS yog qhov zoo dua ntawm no, vim tias tsis yog txhua yam khoom siv tuaj yeem tiv taus kev hloov pauv ntawm lub zog. AVR zoo li cas? Nws yog dab tsi thiab nws ua haujlwm li cas? Cov cuab yeej no pom meej meej hauv daim duab yooj yim.
- Relay EL-11 tswj peb-theem voltage, saib xyuas cov theem tsis sib xws, lawv tawg thiab hloov pauv.
- Electromagnetic relays nrog cov neeg muaj zog yog siv los txuas cov khoom thauj. Nyob rau hauv ib txwm hom, lub kauj ntawm lub magnetic starter ntawm lub ntsiab input yog powered los ntawm nws thiab nrog nws cov neeg KM 1 txuas lub hwj chim mov rau lub load.
- Thaum qhov hluav taws xob hauv qhov hluav taws xob tseem ceeb ploj mus, relay KM 1 tig tawm thiab lub hwj chim tau muab rau lub kauj ntawm relay KM 2, uas txuas cov kev tawm tswv yim thaub qab.
Lub tswv yim ATS no tuaj yeem siv rau hauv tsev ntiag tug, cov tsev lag luam thiab kev tswj hwm, qhov twg qhov hloov pauv mus txog kaum tawm kilowatts. Qhov tsis zoo ntawm Circuit Court yog qhov nyuaj ntawm kev xaiv ib qho relay rau cov dej ntws siab. Nws tseem yog qhov tsim nyog rau kev hloov cov neeg siv hluav taws xob tsawg, tab sis rau cov khoom hnyav nws yog qhov zoo dua los siv ATS pib lossis triac.
Qhov tseem ceeb ntawm lub zog ntxiv yog roj av lossis diesel generators. Cov tom kawg tau pom cov ntawv thov dav vim lawv txoj kev lag luam thiab lub zog loj dua. Kev ua lag luam muaj ntau yam ntawm cov tshuab hluav taws xob diesel (DGS) uas muaj kev tiv thaiv ntau dhau.
ATS haujlwm
ATS ua haujlwm li cas? Nws yog dab tsi nyob rau hauv cov nqe lus ntawm kev ntseeg siab nyob rau hauv kev muab hluav taws xob rau cov neeg siv khoom? Cov khoom siv tau muab faib ua 3 pawg. Cov khoom siv hluav taws xob ntawm tsev nyob yog qhov qis tshaj plaws. Nrog tsis tshua muaj hluav taws xob tsis zoo, nws yog qhov zoo dua rau nruab ib qho chaw cia hauv tsev, txij li qhov ua tau zoo ntawm cov khoom siv hauv tsev, nrog rau kev nyob zoo, nyob ntawm qhov no. Cov roj teeb uas tsis muaj kev cuam tshuam tau teeb tsa hauv cov tsev, uas yog siv rau cov khoom siv hluav taws xob. Cov tshuab hluav taws xob feem ntau yog cov khoom siv hluav taws xob standby rau cov tsev ntiag tug.
Qhov yooj yim tshaj plaws ntawm lub tshuab hluav taws xob roj av txuas nrog lub zog ntawm lub tsev los ntawm kev hloov pauv hloov. Qhov no tiv thaiv luv luv Circuit Court nyob rau hauv cov kev tshwm sim ntawm ib tug yuam kev input ntawm lub cia, thaum lub hwj chim tsis siv neeg muab khoom siv rau lub tsev yog tsis muab tua. Qhov hloov pauv tau xaiv nrog peb txoj haujlwm, qhov nruab nrab ntawm lawv txiav tawm hluav taws xob tag.
Ua-nws-koj tus kheej ATS tuaj yeem ntsia tau rau hauv hom tsis siv neeg yog tias koj nruab lub tshuab hluav taws xob nrog lub tshuab pib tsis siv neeg thiab tswj nws los ntawm lub txee siv cov contactors uas kuj hloov cov khoom siv. Automation ua haujlwm ntawm microprocessor tswj, piv txwv li, ntawm Ib qho yooj yim relay controllers. Voltage sensors yog siv los nkag rau ATS cia. Thaum lub hwj chim kaw lawm, lub tshuab hluav taws xob lub cav pib tam sim ntawd. Nws yuav siv sij hawm qee lub sij hawm kom ncav cuag hom kev khiav hauj lwm, tom qab ntawd ATS hloov cov khoom thauj mus rau qhov chaw cia. Cov kev ncua sij hawm zoo li no tau txais rau cov kev xav tau hauv tsev.
Automatic Generator Start Unit (bag)
AVR yog ib qho system ntawm lub tsev ntiag tug uas muab kev pib thiab tswj lub tshuab hluav taws xob thaub qab thaum muaj hluav taws xob tsis ua haujlwm. Lub tom kawg yog nruab nrog ib qho tshwj xeeb BAZG chav tsev, uas yog ib qho kev daws teeb meem pheej yig rau lub zog tsis ua haujlwm hauv lub network loj. Nws ua rau tsib sim pib li ntawm 5 vib nas this hauv txhua lub sijhawm tom qab qhov hluav taws xob ntawm cov tswv yim tseem ceeb ploj mus. Tsis tas li ntawd, nws tswj cov huab cua damper, kaw nws thaum lub sijhawm tso tawm.
Yog tias qhov hluav taws xob tshwm sim dua ntawm cov tswv yim tseem ceeb, lub cuab yeej hloov lub load rov qab thiab nres lub tshuab hluav taws xob. Thaum lub tshuab hluav taws xob tsis ua haujlwm, cov khoom siv roj raug thaiv los ntawm electromagneticvalve.
Txoj haujlwm ntawm ATS kev ua haujlwm ntawm lub tsev ntiag tug
Txoj kev uas feem ntau yog nrog ob lub tswv yim, qhov twg thawj cov tswv yim ua ntej. Thaum txuas nrog lub network, cov khoom siv hauv tsev feem ntau ua haujlwm ntawm ib theem. Thaum nws ploj mus, nws tsis yog ib txwm yooj yim los txuas lub tshuab hluav taws xob. Nws yog txaus mus txuas rau lwm txoj kab raws li ib tug thaub qab. Nrog rau peb-theem input, lub hwj chim yog tswj los ntawm ib tug relay ntawm txhua theem. Thaum qhov hluav taws xob tawm ntawm qhov ntau, cov theem contactor kaw, thiab lub tsev yog siv los ntawm ob theem ntxiv. Yog tias lwm txoj kab ua tsis tiav, tag nrho cov khoom thauj tau rov xa mus rau ib theem.
Rau lub tsev me me lossis dacha, DGU nrog lub zog tsis tshaj 10 kW yog siv rau cov ntaub thaiv npog ua haujlwm ntawm 25 kW. Xws li lub tshuab hluav taws xob yog qhov txaus los muab lub tsev nrog qhov tsim nyog tsawg kawg nkaus ntawm hluav taws xob rau lub sijhawm luv luv. Thaum muaj xwm txheej ceev, qhov hluav taws xob tswj relay hloov cov neeg siv lub tsheb npav mus rau lub zog thaub qab thiab muab lub teeb liab pib lub tshuab hluav taws xob diesel. Thaum lub zog tseem ceeb rov qab los, lub relay hloov mus rau nws, tom qab ntawd lub tshuab hluav taws xob nres.
Txuas ntxiv ntawm ATS cov haujlwm
Programmable logic controllers (PLCs) yog siv los tswj cov kab hluav taws xob hluav taws xob raws li kev xaiv algorithms. Lawv twb muaj cov kev pab cuam ATS, uas tsuas yog yuav tsum tau teeb tsa los siv ib hom kev ua haujlwm. Kev siv PLC, xws li AC500 maub los, ua kom yooj yim rau cov hluav taws xob circuits, txawm hais tias thaum xub thawj siab ib muag cov cuab yeej zoo li nyuaj. ATS tswj tau muab tso rau ntawm lub qhov rooj switchboardnyob rau hauv daim ntawv ntawm ib txheej keyboards, nyees khawm thiab indications.
Cov software twb tau suav nrog hauv cov kev daws teeb meem. Nws tau nruab rau hauv PLC.
Zaj lus
Lub zog tsis ua haujlwm tuaj yeem ua rau muaj ntau yam tsis zoo rau cov neeg siv khoom. Cov neeg siv feem ntau tsuas muaj lub tswv yim tsis meej txog ATS. Nws yog dab tsi, ntau yam tsis paub txhua thiab coj cov khoom uas tsim los rau lub hom phiaj sib txawv kiag li raws li cov khoom siv. Vim tias cov khoom siv hluav taws xob muaj nqi siab, nws yog ib qho tseem ceeb uas yuav tau xaiv qhov kev hloov mus rau txoj cai. Qhov no yuav tsum tau muaj cov lus qhia tshwj xeeb. ATS tso cai rau koj kom ua tau zoo ntawm cov khoom siv hauv tsev thiab cov khoom siv uas lub zog tas li yog qhov tseem ceeb.
