Pregled izdelka
Električni aparat tipa RHP HGIS je nova vrsta visokonapetostne električne opreme. Ohranja prednosti kombinirane GIS električne opreme, kot so kompaktnost, visoka zanesljivost in nizki zahtevi glede upravljanja in vzdrževanja, hkrati pa inovativno ohranja busbar v običajni AIS razpostavitvi za namestitev in povezavo na mestu. Ta dizajn učinkovito premoči pomanjkljivosti, povezane s tradicionalno AIS opremo, kot so velika površina, veliko število povezovalnih točk in visoke obremenitve glede pregledovanja in vzdrževanja.
Ustreza 40.5 kV do 145 kV in nižjim sistemom prenosa in distribucije v elektrarnah, podstanicah, železniških postajah, pristaniščih in velikih industrijskih in rudarskih podjetjih. Zlasti je primerna za projekte z omejenim prostorskim prostorom, kot so podstanice v gorskih območjih in urbanih podstanicah, ter se lahko namešča znotraj, zunaj ali na strehah.
Sestavni deli izdelka
Glavne značilnosti
Prava rešitev za izzive zanesljivosti pri odskrivanju/peščenju;
Napredna samozapalna prekinitvena tehnologija in modularna struktura za izboljšano zanesljivost;
Zmanjšanje ali značilno zmanjšanje diskastih izolatorjev za izboljšano zanesljivost;
Uporaba specializiranih proizvodnih tehnik zmanjša število flančnikov, s tem pa tudi možnost utrke plina；
Zunanje montiran CT za izboljšano varnost in zanesljivost;
Kompaktna struktura in prožna razpostavitev;
Relativno bolj ekonomično kot AIS.
