      FZN25戶內高壓負荷開關,是上海人民電氣有限公司 http://www.hqbet5695.com 為您提供的關于FZN25戶內高壓負荷開關型號,F(xiàn)ZN25戶內高壓負荷開關價格,有關FZN25戶內高壓...

    產(chǎn)品介紹

    FZN25、FZRN25型 真空負荷開關和組合電器,適用三相交流50Hz環(huán)網(wǎng)或終端供電和工業(yè)用電設備中,作負荷控制和短路保護之用,負荷開關分合負荷、閉環(huán)電流、空載變壓器和電纜充電電流。組合電器可以開斷直至額定短路電流的任何電流。采用直動式隔離斷口和真空滅弧室聯(lián)動。具有手動和電動功能。
    FZN25、FZRN25獨特的傳動結構設計,滅弧室僅在關合和開斷的瞬間承受高壓,故體積小,重量輕。
    FZN25、FZRN25可實現(xiàn)隔離斷口和滅弧室斷口的一次性操作。
    FNZ25、FZRN25在靜觸頭與動觸頭導電筒之間有與接地開關互為聯(lián)動的接地活門,既保證了安全又方便了檢修。

    使用環(huán)境

    周圍空氣溫度:上限+40℃;下限-25℃(允許在-30℃儲運)
    空氣相對濕度:日平均值不大于95%,月平均值不大于90%
    地震烈度:不超過8度;海拔:1000mm
    周圍空氣不受腐蝕性或可燃性氣體、水蒸氣等明顯污染
    無經(jīng)常性劇烈振動;污染等級:H級

    引用標準
