Paliwanag:
Ang malaking inobasyon ay naitatag sa pamamagitan ng integrasyon ng teknolohiya. Sa pag-combine ng karanasan sa pagbuo ng produktong air-insulated switchgear at gas-insulated switchgear, ang QGG Series Solid Insulated Switchgear ay nabuo, na nagpapakita ng malaking pagbabago sa larangan ng medium-voltage technology at may mataas na operational safety. Bilang core unit ng power distribution network, ito ay ginagamit sa mga power distribution network. Ito ay gumagamit ng vacuum interrupter para sa arc extinction, at ang kanyang high-voltage live parts ay gawa mula sa solid insulating materials na may kamangha-manghang insulating performance (epoxy resin materials), na nagwawala ng air chamber na may presyur na 0.03Mpa at nagpapatupad ng full insulation, full sealing, at maintenance-free operation. Ang QGG Series Solid Insulated Switchgear ay may intelligent online monitoring system, na real-time na naga-monitor ng estado ng mga key components sa loob ng switchgear, nakukuha ang status parameters, awtomatikong pinapahusay ang posibilidad ng mga fault, at nagbibigay ng matibay na proteksyon para sa normal na operasyon ng switchgear at ng buong power distribution line. Matapos ang ilang taon ng dedikadong R&D, ang solid insulated switchgear ay naging IV product series, bawat isa ay may sariling natatanging katangian.
