Produktopsig
Die RHP-tipe HGIS-elektriese toerusting is 'n nuwe tipe hoëspanningselektriese toerusting. Dit behou die voordele van GIS-gecombineerde elektriese toerusting, soos kompaktheid, hoë betroubaarheid en lae bedryfs- en instandhoudingsvereistes, terwyl dit innoverend die buslei as 'n konvensionele AIS-uitspanning behou vir plaaslike installasie en verbinding. Hierdie ontwerp oorkom effektief die nadele geassosieer met tradisionele AIS-toerusting, insluitend groot grondspoor, talryke verbindingpunte, en hoë inspeksie- en instandhoudingswerklast.
Dit is geskik vir 40.5kV tot 145kV en onder transmissie- en verspreidingsisteme in kragstasies, transformasiesentrales, spoorwegstasies, hawens, en groot industriële en mynbouondernemings. Dit is veral geskik vir projekte met beperkte ruimte, soos bergtransformasiesentrales en stedelike transformasiesentrales, en kan binne, buite, of op dakkappe geïnstalleer word.
Produkkomponent
Hoofkenmerke
Egte Oplossing vir Operasionele Betroubaarheidsuitdagings in Afsonderaar/Aardingsskake;
Gevorderde Self-ontploffende Onderbreking en Modulaire Struktuur vir Verbeterde Betroubaarheid;
Die eliminasie of aansienlike vermindering van skotelvormige isolatoren vir verbeterde betroubaarheid;
Die toepassing van gespesialiseerde vervaardigingstegnieke vermindert die aantal flenkses, wat die potensiaal vir gaslekkage minimeer;
Buite gemonteerde CT vir verbeterde veiligheid en betroubaarheid;
Kompakte Struktuur en Buigsame Uitleg;
Relatief meer ekonomies as AIS.
