GIS Cov Khoom Siv Ib Feem Tshem Tawm Hauv Online Saib Xyuas Qhov System

MOEORW-W5086U GIS Ib Feem Kev Tso Tawm Hauv Online Saib Xyuas Kev Ua Haujlwm yog tus kheej tsim los ntawm nruj raws li kev lag luam hluav taws xob ua tiav nrog rau IEC 60270, GB/T 7354, Xeev Grid Q/GDW 11059.1/2 GIS Ib Feem Tso Tawm Nyob Hauv Kev Ntsuas Cov Lus Qhia thiab Tuam Tshoj Southern Power Grid dual 110 CS kev txhawb nqa. technologies ntawm Ultra-High Frequency (UHF) thiab hu rau ultrasonic, thiab paub nyob rau hauv- kab hauv internet saib xyuas rau txhua yam ntawm 72.5kV thiab saum toj no GIS roj insulated switchgears. Lub kaw lus sib koom ua ke peb txoj kev sib txuas lus ywj pheej: optical fiber, LoRa wireless thiab 4G tag nrho - kev sib txuas lus hauv network. Cov neeg yuav khoom ntau tuaj yeem xaiv cov phiaj xwm kev sib txuas lus ywj pheej raws li qhov tseeb substation site cov xwm txheej yam tsis muaj cov qauv sib txawv, uas txo cov neeg muag khoom cov khoom lag luam siab. Cov cuab yeej tuaj yeem ntes cov kab hluav taws xob tsis zoo hauv GIS xws li cov khoom siv hlau, rwb thaiv tsev cov pa tawm thiab cov lus tso tawm, nrog rau qhov tsawg kawg nkaus pom cov teeb liab tawm ntawm 5PC. Nws kwv yees qhov kev puas tsuaj ntawm cov rwb thaiv tsev ua ntej kom tsis txhob muaj xwm txheej hnyav xws li GIS flashover thiab tag nrho - chaw nres tsheb fais fab tuag, thiab ua raws li tag nrho cov kev qhia tshwj xeeb rau kev sib tw fais fab ntawm substation online xyuas cov cuab yeej.

1.Ultra-Kev tshawb pom siab rhiab heev npog tag nrho cov teeb meem me me: Lub kaw lus tuaj yeem ntes cov teeb liab tawm tsawg li 5PC. UHF sensor ua haujlwm nyob rau hauv 300 ~ 1500MHz zaus band nrog kev tshawb nrhiav rhiab heev ntawm -80dBm thiab ntsuas ntau ntawm -80 ~ 0dBm. Chav tsev tau txais tau nruab nrog 125MS / s sampling tus nqi thiab 14-ntsis high-precision ADC nti, txhawb nqa 6-channel synchronous sau thiab ntes cov cim ntawm 50 ua tiav lub zog zaus zaus ib zaug, nrog ob lub suab nrov txo ntawm ntau theem kho vajtse lim thiab siab txiav txim siab digital lim. Cov khoom siv hluav taws xob ib nrab ntawm kev ua lag luam tsuas tuaj yeem txheeb xyuas qhov muaj zog tshaj 20PC, thaum peb cov khoom tuaj yeem ntes cov hluav taws xob tsis muaj zog thaum lub hli ua ntej, txhim kho qhov kev lees paub ntawm tus neeg siv khoom lub chaw nres tsheb thiab pab cov neeg siv khoom loj los yeej lub zog hluav taws xob engineering.

2. Muaj zog tiv thaiv- cuam tshuam thiab siab voltage poob siab rau kev ua haujlwm ruaj khov nyob rau hauv ib puag ncig electromagnetic complex: Tag nrho lub tsev tuaj yeem tiv taus 600kV flashover shock yam tsis muaj kev puas tsuaj lossis cov ntaub ntawv poob. Nws siv sijhawm sib koom ua ke-domain thiab zaus-domain cuam tshuam kev sib cais algorithm, ua ke nrog rau pem hauv ntej-kawg coaxial shielding thaiv thiab ntau-stage hardware filtering, kom zoo lim electromagnetic cuam tshuam los ntawm substation inverters, hloov kev ua haujlwm thiab kev sib txuas lus sab nraud clutter, txo qis kev ua haujlwm thiab kev ua haujlwm qis dua 8} cov neeg siv khoom.

3.High-precision synchronization rau ntau yam khoom siv thiab loj -scale faib network: Lub sij hawm synchronous sib txawv ntawm tag nrho cov khoom tau txais tsawg dua 100ns, txhawb ob qho tib si sab nraud voltage synchronization thiab sab hauv theem synchronization. Ib cov ntaub ntawv concentrator tuaj yeem txuas rau kaum ob ntawm qhov tau txais, thiab ntau qhov chaw saib xyuas yuav raug cuam tshuam los ntawm kev siv fiber ntau los tsim cov kev soj ntsuam hauv cheeb tsam loj, nrog peb hom kev sib txuas lus (optical fiber, LoRa, 4G) rau cov xwm txheej sib txawv. Loj -tej kev kho dua tshiab ntawm lub nroog cov phiaj xwm hluav taws xob thiab ntau- chaw nres tsheb tuaj yeem tswj hwm hauv nruab nrab, txiav tus neeg siv khoom tag nrho tus nqi thiab nce cov nyiaj tau los rau cov khoom tiav.

4.Edge kev suav hauv zos uas tsis muaj cov ntaub ntawv poob hauv kev sib txuas hauv network thiab dual - cov ntaub ntawv davhlau ya nyob twg rov qab: Lub ntug kev suav module ua hauv cov khoom tau los suav cov nqi tso tawm ib nrab, cov txiaj ntsig zoo thiab cov yam ntxwv hauv zos thiab caches cov ntaub ntawv ntawm -site. Cov ntaub ntawv ploj lawm yuav raug xa mus tom qab lub network rov qab. Nws txhawb nqa ob cov ntaub ntawv khaws cia ntawm cov servers hauv zos thiab huab platforms. Rau cov chaw hauv roob uas tsis muaj zog 4G cov cim qhia, cov ntaub ntawv tsis raug cai tuaj yeem khaws cia kom ua tiav thiab taug qab cov ntaub ntawv rau qhov kev lees paub.

5.Non-kev puas tsuaj GIS kev teeb tsa nrog lub sijhawm siv luv luv: Sab nraud UHF sensors tau nruab rau ntawm GIS phiab insulators thiab txuas nrog 50Ω shielded coaxial cables, tsis muaj kev puas tsuaj rau cov qauv sib khi lossis thawj qhov kev ua tau zoo ntawm GIS enclosures. Tag nrho cov cuab yeej siv phab ntsa-mounted installation; tsis muaj GIS siab nyem los yog tag nrho - chaw nres tsheb fais fab txiav yuav tsum tau kho dua tshiab, txiav ib zaug - lub sij hawm tsim kho los ntawm 70% thiab txo nqi zog rau cov neeg ua haujlwm engineering.

6.Distributed tsis siv neeg txheeb xyuas thiab nthuav dav yam tsis muaj re-commissioning rau tom qab ntxiv: Nrog networked faib layout, thaum ntxiv los yog tshem tawm cov khoom tau los thiab sensors, lub keeb kwm yav dhau software cia li scans, txheeb xyuas thiab configures parameters los ntawm cov cim SN code ntawm txhua lub cuab yeej, tsis muaj phau ntawv hloov kho ntawm lwm yam kev pab cuam. Nws yoog mus rau phased technical renovation tej yaam num ntawm substations, yooj yim phased xa rau tej cov neeg muas zaub thiab nce rov txiav txim.

7.Real-time multi-theem ceeb toom ntxov thiab tsis siv neeg GIS tso tawm qhov chaw tsis raug: Cov khoom siv sau tiag- lub sijhawm tso tawm ib nrab ntawm lub sijhawm sib txawv thiab tshwm sim ceeb toom thaum cov teeb liab tshaj qhov pib. Nws suav cov haujlwm tsis raug los ntawm lub sijhawm sib txawv algorithm ntawm ntau-sensor signals, thiab muab ntau- cov kab kos duab tsom xam suav nrog 2D-PRPD, 3D-PRPS, theem kab teeb tsa thiab 30- hnub sib kab kab kab kos. Lub tsim-hauv kev lag luam fais fab kev lag luam ib feem tso tawm cov kws tshaj lij cov ntaub ntawv tau txais qhov txawv txav ntawm cov pa tawm, cov khoom siv hlau thiab cov pa tsis zoo, tshem tawm phau ntawv bay- los ntawm kev tshuaj xyuas los ntawm bay thiab ua kom lub sijhawm ua haujlwm tsis raug cai.

Kev soj ntsuam tag nrho muaj plaub yam khoom siv kho vajtse thiab keeb kwm yav dhau los txheeb xyuas software, txhawb nqa cov khoom sib cais ntawm ib qho lossis ua tiav kev sib tw. Cov npe khoom kho vajtse yog raws li hauv qab no:

1.UHF sensors: sab nraud thiab sab hauv hom xaiv, kev khiav hauj lwm zaus band 300 ~ 1500MHz, matched nrog standard 50Ω shielded coaxial kis cables;

2.6-channel ntse ib feem tso tawm nrhiav kom pom chav tsev: rau 6 synchronous acquisition channels sib xws nrog optical fiber, LoRa thiab Ethernet cov ntaub ntawv tso tawm interfaces;

3.Online soj ntsuam cov ntaub ntawv concentrator: phab ntsa-mounted thiab 1U khib-mounted specifications muaj, uniformly sau tag nrho cov kev soj ntsuam cov ntaub ntawv los ntawm acquisition units thiab txuas mus rau lub zos substation servers los yog tej thaj chaw deb huab platforms;

4. Ib nrab tso tawm hauv online saib xyuas keeb kwm yav dhau software: BS lub vev xaib tsis muaj kev teeb tsa hauv zos, txhawb nqa ntau-account hierarchical txoj cai tswj hwm, tsis siv neeg xa tawm ntawm kev soj ntsuam cov ntaub ntawv ceeb toom thiab tsis siv neeg GIS qhov chaw tsis raug.

Lub kaw lus tau nruab nrog peb txoj kev ywj pheej sib txuas lus topology (optical fiber, LoRa, 4G) rau kev xaiv yooj yim raws li cov chaw nres tsheb thaiv kab mob thiab thaj chaw thaj chaw.

Targeted ntawm tej B- kawg buyers nyob rau hauv lub hwj chim kev lag luam, qhov system no muaj feem xyuam rau tag nrho cov hom ntawm high-voltage GIS engineering tej yaam num, npog cov nram qab no scenarios: ua tiav cov kev txhawb nqa rau GIS ntawm tshiab

ua 72.5kV ~ 550kV substations; nyob - kab hauv online saib xyuas kev kho dua tshiab rau hauv - cov khoom siv GIS; ntev- lub sij hawm rwb thaiv tsev kev soj ntsuam ntawm siab-voltage GIS nyob rau hauv cua zog, photovoltaic thiab lub zog cia booster chaw nres tsheb; ua kom tiav kev ua haujlwm hauv nruab nrab thiab kev saib xyuas kev saib xyuas lub platform rau ntau- chaw nres tsheb hauv nroog- qib hluav taws xob; tiag-lub sijhawm tiv thaiv kev noj qab haus huv xyuas cov haujlwm rau siab-voltage GIS switchgears hauv thermal thiab hydropower nroj tsuag.
