Paliwanag：
Ang serye ng QEFG na mga gas switch cabinet na pang-ecology ay isang uri ng gas switch cabinet na independiyenteng inihanda, na gumagamit ng ligtas at pang-ecology na halong gas upang palitan ang SF6 bilang insulating medium sa gas chamber, kaya't nasolusyonan ang problema ng pagkalason dahil sa pagbabawas ng gas na SF6. Ito ay may mataas na antas ng seguridad sa operasyon at naglilingkod bilang core unit sa distribution network, na inilapat sa loob ng distribution network. Ang equipment ay banyaga nakaorganisa sa modular components tulad ng sealed switch gas chamber, cable room base, mechanism room, at instrument room, kung saan ang core components ay kinabibilangan ng sealed circuit breaker switch body, load switch body, three-position isolation grounding switch body, at environmentally friendly insulating sleeve, na nagpapahayag ng ganap na sealed, maintenance-free structure.
Ang vacuum circuit breaker at vacuum load switch ay gumagamit ng universal main structure design, na mas maayos na nag-aasikaso ng konsistensiya ng switch body; ang pagsara at pagbukas ng main circuit ay natutugunan gamit ang simple at reliable spring mechanism, na may knob para sa pagsara at pagbukas; ang three-position isolation grounding switch ay gumagamit ng mature knife switch structure, na inherent na nagpapahintulot ng panganib ng main conductive circuit na may enerhiya habang konektado sa ground.
Ang serye ng QEFG na mga gas switch cabinet na pang-ecology ay kasama ng intelligent online monitoring system na real-time na naghahanap ng estado ng mga key parts sa loob ng switch cabinet, nakukuha ang status parameters, at awtomatikong nag-assess ng posibilidad ng pagkakaroon ng mga fault, na nagbibigay ng malakas na assurance para sa normal na operasyon ng switch cabinet at buong distribution line.
Mga Karaniwang Application
