I-HP-MVnex: Yeyona Indlela Ekuhle Kolawulo Lwevoltage?

Yeyona nto engcacisa i-HPMVnex kwiindawo zevoltage ephakeme

Le ndawo ikhawuleza ngokusekelwe kule me:

• Ukubonakala Olunamathela : Ikuvumela ukutshintshwa kweqela ngaphandle kokuchitha amanye amaqela, okuncipisa isikhathi esidingekayo ngama-40%.
• Ukugcinwa Ngokwemiqolo : Uqondanisa ukugcinwa ngokwemoto kunye neemix yeminye imifume, ukufikelela kumathuba we-99.9% yokuncipisa umoya olungileyo.
• Ukuhlanzeleka Okuhlelwa : Iisensile zokungenisa zilandela ukuxhuma kwi-SCADA kwiimephu ezigcinweyo.

Iingxenzo Ezinxulumene Neempawu Zokusebenza

Iimpawu eziphambili zixhomekeka ukusebenza ngokupheleleyo:

1. Iibhreykhi Zokugqibela : Yeqa iindleko kwi-25 ms (⏃Â 40 kA).
2. Ukwahlulwa Kwemigca : Ukwahlulwa phakathi nokuseleyo kwe-epoxy kubangela ukungqina kwezifayile.
3. Iidijithali Zokugcina : Jonga indawo yokugcinwa/ngokwezifuba ngokudibanisa IEC 61850.
4. Ukuvuseleka okusebenzayo : Kuphumelela ukuhamba phambili (-25°C ukuya ku +55°C) ngokwemigqa esebenzayo.

Imiphumakelo yeNdawo Ehlukahlukene nezinto

• Ukuvikela Imiphumela : Ivesi eline 5mm lihlukanisa izindawo zokungena kwe-arc ku <0.5 m³.
• Ubungqina bokusebenza : Izinhlelo zemhla ngaphambili zivumela ukuthi kubekwe amaqhinga esikhatsi ku <20 imizuzu.
• Ukulindelana nendawo : Amaphaneli aphumelela IP54 aqinisekisa ukungena kwesibhakabhaka/ukukhanya kwezimali ezikhundleni eziphakeme.

Lesi sivumelwano senza ukuthi kwehlise ukungena kwezinsizwa ku <0.03% ngonyaka kuzemaphakathi amathile.

Ukudijithalisa nokuxhumeka kweGrid esemkhathini

Izindlela Zokugcina Dijithali

I-HPMVnex integrita ama-senzor ye-IoT ukugcina ngokushesha okuphawulwa, ama-loyi, nezimvume ze-arc-flash. Ukuthunyelwa kwezethuwele kwenziwa ngokulandelana nokulawulisa ama-loyi, kuthula ama-outages engavumelekile umkhawulo we-42%. I-edge computing enqaba ukuzalwa kwezikhathi ukulungisa izimo.

Ukugcina Okuhlelwa Ngokuthuthukiswa Kwezibonelo

Ukufundisa kwezibonelo kubonisa ukuthula kwezinsiza nezindlela zokugcina, kuthula ukugcina okulandelana noma-55%. Ukugcina ngokushesha kuthula ukunquma kwezimo ngaphakathi.

Isibonelo: Ukusebenza Kwemithi

Indhini yezimoto yathola ukuthula kwezimo ngokushesha, kuthula izindleko zokuthintwa kwe-$1.2M. Izibonelo zokuthuthukiswa zathola izimvume ezi-23 ngokushesha, ukufikelela kwe-99.96% kwezimo zokusebenza ngemva kwezinyanga e-18.

Ukuthuthukiswa Kwemithi

Ama-relay wokugcina okuhlelwa kubonisa ukuthuthukiswa kwezimo, kuthuthukisa imithi yezinhlobo e-150MW ngemva kwe-0.5 seconds. Ukuthunyelwa kwezethuwele kubonisa ukuthuthukiswa kwezimo, kuthuthukisa amastandad xa kuthathwa izindleko.

Ukuthuthukiswa Nezinovuyo Ngaphandle kwe-SF6

Ukuthuthukiswa Kwemithi Ngaphandle kwe-SF6

I-Sulfur hexafluoride (SF6) inikhipha yokuphakama kweglobal warming 23,500 ngaphezulu kuka-CO₂. I-EU lidikisela ukuthintela kuka-70% kuka-SF6 ukuze kube yilapho 2030, kuyindlela yokuthuthukisa ukunqatha kwezinye izinhlelo.

Imishilo yokuqinisa kanye nezinhlelo zomoya oluncle

Ukuqalwa ngokuphapha (awukho ukuphuma kwezimali) kunoma umoya oluncle (GWP <1) ubonisa ukukhanya okufanayo. Izindlela zokuhlinzwa kubonisa ukuthintela kuka-92% ngaphansi kwezinhlelo zika-SF6.

Ukusebenza kuka-HPMVnex kungani na-SF6

Ngokuyindlela yokuthintela ngokuphapha kunoma umoya oluncle, le nhlelo ekwenza ukuthintela kungaba ngu-99.9% - ikhuluma ngokufanayo nezinhlelo zika-SF6 ngokwesiqephu se-IEC.

Ukuthwalela kwezinyathelo zokuthiwa

Noma amathela yokuqala ayibe phezulu kabili ngama-20%, amathela wezinyathelo ezinzile ayibe ngu-30—40% ngemva kama-15 iminyaka. Izinhlelo ezingenakuhlelwa kakhulu kanye nezibongo (isb., Global SF6-Free Alliance) zikhathazelela ukuguqula.

Isakhiwo esifanelekile esikhulu esenzekelayo kwezindawo zomuntu

Ukusebenzisa indawo ngokwehlanzekile

Ukuqinisekisa ukuthintela kuka-HPMVnex kungabangela ukuthintela kwe-40%, kuyindlela yokuthiwa kwezindawo zezindawo zomuntu. Ukulayisha ngokwesibaya kunoma izinhlelo eziyisisekelo zikakhelwe indawo.

Ukuhlelwa Kwemithambo Yasekile

Izinto ezifakwe kwi:

• Izivumelwano zasebusbari zokungenisa (ukwenza amandla kuvoltage kugcina ema-48 amahora)
• Imoduli yeminye yekhono
• Izivumelwano ezinokukhulisa (25—63 kA)

Ukufakwa Okulula

Imoduli ebalwe ngaphambi kuyahlula isikhathi sokuhlelwa kabangela, noma kunezindawo zokwakha ngokuzayo. Isisbenzi seMetro ye-2023 ishukumele isix moduli ngaleli xesha elilodwa.

Ukufakwa Kwesintsi Sokuvela

Izinkinga Zokuvuselela Kwematriki

Isiphiwo esahlukahlukene solare/ingceke sibophelela umthamo wokusebenza omdala—42% yemigomo ineeda imithambo yokuqhela kancinca kancinci kokuqhela.

Izisombululo eziqandwe zika HPMVnex

Izilinganiso zokugcinwa kwekurrenti ezingxenye ukwandisa amandla ngo-15—30% ngokwesicatshulwa sevimba. Ukulawulwa kwesivoltaji kuyakha ukuguqulwa kwe±1% xa kune ukuphakama kwezindlela zokubuyisa kakhulu ngaphezulu kwe-80% (kufanele ne-IEC 61850-7-420).

Isicatshulwa: Isikolelo se-Solar-Wind

Isikolelo esiphindaphindayo esingama-150MW sikhuphele ukungena kwezinsuku zokulotwa ngo-67%, ukungena kwe-$2.8M ngonyaka. Ngesikhathi sokugcina kwegcina, izimizuzwana ezingama-3 sikhuphele ukungenakwa kwe-$740k ekupeleni.

Ukulungisa Imigwa Yezokudla

Lo mmandla ongeke uyasebenzisa i-SF6 asula i-1.2M kgCO2e ngasinye isikolelo ngemva kwezinyaka ezi-15. Iindlela zokusebenza kwezinye zokudla zilinganisa ukungena kwezindlela, zikhupha ukulahlelwa kwezindlela zokubuyisa ngo-18%. Ukwehla kwezinto kuyavumela ukusebenzela ngemva kwezinyaka ezi-25.
