    YH5CX-13/40架空絕緣導線過電壓保護器

    YH5CX-13/40架空絕緣導線過電壓保護器

     

     正常使用條件

    YH5CX-13/40架空絕緣導線過電壓保護是一種穿刺絕緣導線型組合式結構保護器。它的正常適用條件為:

    1、環境溫度不高于+40℃,不低于﹣ 40℃;

    2、太陽光日照0.1w/cm2;

    3、海拔不超過1000m;

    4、電源的頻率不小于48Hz,不大于62Hz;

    5、地震烈度7度及以下地區;

    6、最大風速不超過35m/s;

    7、覆冰厚度不大于2cm;

    8、由于可隨導線弧垂情況調節放電間隙,適用于各種地理環境架空絕緣線路的防雷改造工程;

    9、安裝本體避雷器放電能力 強,通流量大,可避免高低壓放電電極灼燒,使用壽命長。

    產品結構及工作原理

            保護器結構由高壓穿刺電極、避雷器本體和安裝金具三部分組成。由高壓穿刺電極接觸導線線芯引出高電位,與避雷器本體頂端形成串聯間隙。

            保護器工作原理為:正常運行時空氣間隙隔離工頻電壓,避雷器本體幾乎不承受電壓;在感應雷或直擊雷產生的雷電過壓作用下,空氣間隙被擊穿,穿刺電極對避雷器本體頂端放電,此時避雷器呈現低阻抗,將雷電流瀉放,從而保護了絕緣導線。改保護器結構緊湊,對絕緣導線的保護性能優越,即使避雷器本體損壞,高壓穿刺電極依然能起到防弧金具的作用,疏導工頻續流電弧弧根離開導線到電極自身上燃燒,保護導線免于損壞。
