高低壓開關柜是常見的電氣設備之一，但很多人不(bu)太了解其(qi)主要部件(jian)有(you)什么。下文就(jiu)簡單(dan)介紹一下：

一、材(cai)料(liao)。1.冷軋鋼板(ban)(ban)(ban)(用(yong)于(yu)(yu)焊接柜(ju)(ju))；2.鍍鋁鋅鋼板(ban)(ban)(ban)或鍍鋅鋼板(ban)(ban)(ban)(用(yong)于(yu)(yu)組裝櫥柜(ju)(ju))。3.不(bu)銹鋼板(ban)(ban)(ban)(非導(dao)磁)。4.鋁板(ban)(ban)(ban)(非導(dao)磁)。

二、功能(neng)單(dan)元。1.母線(xian)(xian)室。母線(xian)(xian)室設置(zhi)(zhi)在高低(di)壓開關柜的后上方，用(yong)于安(an)裝和布置(zhi)(zhi)三相(xiang)高壓交流(liu)母線(xian)(xian)，并通過(guo)支路母線(xian)(xian)與靜觸頭連接。所有線(xian)(xian)路都用(yong)絕(jue)緣(yuan)套管塑(su)料(liao)密封。當母線(xian)(xian)穿過(guo)開關柜隔板時，用(yong)母線(xian)(xian)套管固定(ding)。如果出現內部故障(zhang)電弧，可以限制事(shi)故向相(xiang)鄰(lin)柜蔓延，保(bao)證母線(xian)(xian)的機械強度。

2.手(shou)(shou)車斷路(lu)器(qi)(qi)室(shi)(shi)。斷路(lu)器(qi)(qi)室(shi)(shi)內安(an)裝(zhuang)有專(zhuan)用導軌，供斷路(lu)器(qi)(qi)手(shou)(shou)車在(zai)室(shi)(shi)內滑動(dong)(dong)(dong)和(he)工(gong)作(zuo)。手(shou)(shou)推車可以在(zai)工(gong)作(zuo)位(wei)置(zhi)和(he)測試位(wei)置(zhi)之間移(yi)動(dong)(dong)(dong)。靜觸(chu)頭(tou)的(de)隔板(閥門)安(an)裝(zhuang)在(zai)手(shou)(shou)車室(shi)(shi)的(de)后壁(bi)上。當手(shou)(shou)車從試驗位(wei)置(zhi)移(yi)動(dong)(dong)(dong)到工(gong)作(zuo)位(wei)置(zhi)時，隔板自動(dong)(dong)(dong)打開，當手(shou)(shou)車反向(xiang)移(yi)動(dong)(dong)(dong)時，完全結合(he)，保證操作(zuo)人員不接觸(chu)帶電體。

3.電(dian)(dian)纜室。電(dian)(dian)纜室可(ke)安(an)裝(zhuang)(zhuang)電(dian)(dian)流互(hu)感器(qi)、接地開關(guan)、避雷器(qi)過(guo)電(dian)(dian)壓保(bao)護(hu)(hu)器(qi)、電(dian)(dian)纜等輔助設備(bei)，底部備(bei)有帶縫(feng)隙(xi)的(de)可(ke)拆卸鋁板，以(yi)保(bao)證現場施工的(de)方便。4.繼(ji)電(dian)(dian)器(qi)室。繼(ji)電(dian)(dian)器(qi)室面板上安(an)裝(zhuang)(zhuang)有微(wei)機保(bao)護(hu)(hu)裝(zhuang)(zhuang)置、操作手柄、保(bao)護(hu)(hu)出(chu)口(kou)壓板、儀表、狀(zhuang)態指示器(qi)或狀(zhuang)態顯示器(qi)。在繼(ji)電(dian)(dian)器(qi)室中(zhong)，安(an)裝(zhuang)(zhuang)接線盒、微(wei)機保(bao)護(hu)(hu)控制電(dian)(dian)路DC電(dian)(dian)源(yuan)開關(guan)、微(wei)機保(bao)護(hu)(hu)工作DC電(dian)(dian)源(yuan)、儲(chu)能(neng)電(dian)(dian)機工作DC電(dian)(dian)源(yuan)開關(guan)或交流電(dian)(dian)源(yuan)開關(guan)，以(yi)及(ji)有特殊要求的(de)二(er)次設備(bei)。
