產品概述
FL(R)N36-12型高壓SF6負荷開關是我公司自主研發生產的10KV高壓開關設備,其各項性能指標達到或超過相關國家標準,已廣泛應用于10KV變配電系統。常作為環網柜、戶外電纜分接箱、戶外開閉所、箱變等高壓設備中的進出線主開關。
性能特點
(1)FL(R)N36-12型高壓SF6負荷開關。開關外殼由加強型環氧樹脂真空澆注成型,殼體內充以1.45bar SF6氣體作為絕緣及滅弧介質;
(2)開關為雙斷口、旋轉式動觸頭,具有合閘、分斷、接地三工位或合閘、分斷、(解鎖)二工位;
(3)開關殼體后部設計有防爆泄壓通道,保障操作人員在極端狀態下不受高溫高壓爆炸氣體傷害;
(4)FLN36-12D/T630-20型SF6負荷開關,配備K型壓縮式單彈簧操作機構。常用干進出線開關柜;
(5)FLN36-12D/T125-50型SF6負荷開關—熔斷器組合電器,配備A型壓縮式雙彈簧操作機構。常用于變壓器等饋電出線柜;
(6)開關本體下部內置電容型傳感器;
(7)開關體積??;
(8)母線縱向排列,與柜體裝配簡單方便,操作靈活可靠,運行安全穩定,壽命期間免維護;
(9)可選配電動操作;
(10)可加裝氣壓表及氣壓接點。
