Paglalarawan ng Produkto
Ang RHP type HGIS electrical apparatus ay isang bagong uri ng mataas na voltaheng kagamitan. Ito ay nagsasama ng mga kakayahan ng GIS combined electrical apparatus, tulad ng kompakto, mataas na reliabilidad, at mababang operasyon at pangangalain, habang naisipang itinatago ang busbar bilang isang regular na AIS arrangement para sa pag-install at koneksyon sa site. Ang disenyo na ito ay epektibong nanalo sa mga hadlang na may kasamang tradisyonal na kagamitan ng AIS, kasama ang malaking sukat, maraming puntos ng koneksyon, at mataas na trabaho sa pagsusuri at pangangalain.
Ito ay angkop para sa 40.5kV hanggang 145kV at ibaba transmission at distribution systems sa mga power plants, substations, railway stations, ports, at malalaking industriyal at mining enterprises. Ito ay partikular na angkop para sa mga proyektong may limitadong espasyo tulad ng mga substation sa bundok at urban substations, at maaaring i-install sa loob, labas, o sa bubong.
Mga Komponente ng Produkto
Pangunahing Katangian
Totoong Solusyon sa mga Hamon sa Operational Reliability ng Disconnector/Earthing Switches;
Advanced Self-Blast Interruption at Modular Structure para sa Mas Mataas na Reliability;
Ang pag-alis o malaking pagbawas ng disc-type insulators para sa mas mataas na reliability;
Ang aplikasyon ng specialized manufacturing techniques na binabawasan ang bilang ng flanges, kaya't minumungkahi ang potensyal para sa gas leakage；
Externally Mounted CT para sa mas mataas na seguridad at reliability;
Kompaktong Estruktura at Flexible Layout;
Relatibong mas ekonomiko kaysa sa AIS.
