    高壓隔離開關(guān)結(jié)構(gòu)解說

    2014/1/8 9:31:28      點(diǎn)擊:
    高壓隔離開關(guān) 有G N 19 - 10 ,G N 19 - 10 C ,相對(duì)應(yīng)類似的老產(chǎn)品有G N 6 - 10 ,G N 8 - 10 ,F(xiàn)以G N 19 - 10 為例,主要包括下述部分:
    導(dǎo)電部分

    由一條彎成直角的銅板構(gòu)成靜觸頭,其有孔的一端可通過螺釘與母線相連接;另一端較短(零件1,2),合閘時(shí)它與動(dòng)刀片(動(dòng)觸頭)相接觸。
    兩條銅板組成接觸條(零件3),又稱為動(dòng)觸頭,可繞軸轉(zhuǎn)動(dòng)一定角度,合閘時(shí)它夾持住靜觸頭。兩條銅板之間有夾緊彈簧(零件4)用以調(diào)節(jié)動(dòng)靜觸頭間接觸壓力,同時(shí)兩條銅板,在流過相同方向的電流時(shí),它們之間產(chǎn)生相互吸引的電動(dòng)勢(shì),這就增大了接觸壓力,提高了運(yùn)行可靠性。在接觸條兩端安裝有鍍鋅鋼片(零件6)叫磁鎖,它保證在流過短路故障電流時(shí),磁鎖磁化后產(chǎn)生的相互吸引的力量,加強(qiáng)觸頭的接觸壓力,從而提高了隔離開關(guān)的動(dòng),熱穩(wěn)定性。
    絕緣部分

    動(dòng)靜觸頭分別固定在兩套支持瓷瓶(零件12)上。對(duì)型號(hào)中帶C的,動(dòng)觸頭固定在套管瓷瓶上。為了使動(dòng)觸頭與金屬的,接地的傳動(dòng)部分絕緣,采用了瓷質(zhì)絕緣的拉桿絕緣子(零件7)。
    傳動(dòng)部分

    有主軸,拐臂,拉桿絕緣子等。
    底座部分

    由鋼架組成。支持瓷瓶或套管瓷瓶以及傳動(dòng)主軸都固定在底座上。底座應(yīng)接地?傊,隔離開關(guān)結(jié)構(gòu)簡(jiǎn)單,無滅弧裝置,處于斷開位置時(shí)有明顯的斷開點(diǎn),其分合狀態(tài)很直觀。
