中(zhong)(zhong)(zhong)(zhong)置柜(ju)(ju)(ju)(ju)(ju)的全稱是(shi)鎧裝移開中(zhong)(zhong)(zhong)(zhong)間(jian)(jian)金屬(shu)封(feng)閉開關(guan)(guan)(guan)設備，分為(wei)(wei)三層結構，上層為(wei)(wei)母線和(he)儀表室（相互隔離），中(zhong)(zhong)(zhong)(zhong)間(jian)(jian)為(wei)(wei)斷路器室，下層為(wei)(wei)電纜室。因(yin)為(wei)(wei)斷路器在中(zhong)(zhong)(zhong)(zhong)間(jian)(jian)曾經，所以(yi)被(bei)稱為(wei)(wei)鎧裝型移開中(zhong)(zhong)(zhong)(zhong)置金屬(shu)封(feng)閉開關(guan)(guan)(guan)設備，簡稱中(zhong)(zhong)(zhong)(zhong)置柜(ju)(ju)(ju)(ju)(ju)。環(huan)網柜(ju)(ju)(ju)(ju)(ju)是(shi)一組(zu)安(an)(an)裝在鋼板金屬(shu)柜(ju)(ju)(ju)(ju)(ju)或組(zu)裝間(jian)(jian)隔環(huan)網供(gong)電單(dan)元的高(gao)壓開關(guan)(guan)(guan)設備，其核心部(bu)分采(cai)用負(fu)荷(he)開關(guan)(guan)(guan)和(he)保險(xian)絲，結構簡單(dan)，體積小(xiao)，價(jia)格低，可提高(gao)供(gong)電參數和(he)性能(neng)和(he)供(gong)電安(an)(an)全，是(shi)中(zhong)(zhong)(zhong)(zhong)壓系統負(fu)荷(he)開關(guan)(guan)(guan)柜(ju)(ju)(ju)(ju)(ju)（包(bao)括組(zu)合電器）的通用名(ming)稱。貴州高(gao)低壓開關(guan)(guan)(guan)柜(ju)(ju)(ju)(ju)(ju)與中(zhong)(zhong)(zhong)(zhong)置柜(ju)(ju)(ju)(ju)(ju)有(you)什么不同(tong)?

　　區別：

　　1.中(zhong)置柜為手車(che)式(可(ke)移(yi)動)開關(guan)(guan)柜KYN28-12(GZS1)高壓開關(guan)(guan)柜外殼，環網柜為固定(ding)開關(guan)(guan)柜；

　　2.環網柜一般采用(yong)負荷開關，中置柜一般采用(yong)斷(duan)路器；

　　3.用(yong)途不同，中柜(ju)(ju)通常被稱為KYN28柜(ju)(ju)，手車式高(gao)(gao)壓(ya)(ya)開(kai)關柜(ju)(ju)，一般用(yong)于保(bao)護后端變(bian)壓(ya)(ya)器或其它高(gao)(gao)壓(ya)(ya)負載(zai)。環網柜(ju)(ju)主(zhu)要(yao)用(yong)于高(gao)(gao)壓(ya)(ya)電源(yuan)(yuan)分配，一路或二(er)路高(gao)(gao)壓(ya)(ya)電源(yuan)(yuan)分為多路高(gao)(gao)壓(ya)(ya)電源(yuan)(yuan)柜(ju)(ju)主(zhu)要(yao)用(yong)于高(gao)(gao)壓(ya)(ya)負載(zai)保(bao)護。環網柜(ju)(ju)有兩種形(xing)式：空(kong)氣(qi)(qi)絕緣和全封閉(bi)(bi)充(chong)氣(qi)(qi)柜(ju)(ju)。空(kong)氣(qi)(qi)絕緣是普通的(de)SF6負荷開(kai)關通過銅排連接(jie)成(cheng)一套系統。除電源(yuan)(yuan)進出線外，全封閉(bi)(bi)充(chong)氣(qi)(qi)柜(ju)(ju)還專用(yong)連接(jie)器，柜(ju)(ju)與柜(ju)(ju)連接(jie)在完整的(de)空(kong)氣(qi)(qi)腔內(nei)，充(chong)滿SF6氣(qi)(qi)體。

　　根據(ju)結構(gou)形(xing)式，貴州高(gao)低壓(ya)開(kai)(kai)(kai)關(guan)(guan)柜(ju)(ju)(ju)可(ke)分(fen)(fen)為(wei)固定式和移(yi)開(kai)(kai)(kai)式。固定開(kai)(kai)(kai)關(guan)(guan)柜(ju)(ju)(ju)主要(yao)有固定開(kai)(kai)(kai)關(guan)(guan)柜(ju)(ju)(ju)KGN和XGN系列，舊(jiu)型號GG-1A基本淘(tao)汰(tai)模型。主要(yao)有移(yi)開(kai)(kai)(kai)式開(kai)(kai)(kai)關(guan)(guan)柜(ju)(ju)(ju)JYN和KYN系列；移(yi)開(kai)(kai)(kai)式開(kai)(kai)(kai)關(guan)(guan)柜(ju)(ju)(ju)內(nei)無(wu)(wu)隔(ge)離開(kai)(kai)(kai)關(guan)(guan)，因(yin)為(wei)斷路器移(yi)動后可(ke)形(xing)成斷開(kai)(kai)(kai)點，因(yin)此無(wu)(wu)需隔(ge)離開(kai)(kai)(kai)關(guan)(guan)。高(gao)壓(ya)開(kai)(kai)(kai)關(guan)(guan)柜(ju)(ju)(ju)按(an)作(zuo)用分(fen)(fen)為(wei)進線柜(ju)(ju)(ju)、饋線柜(ju)(ju)(ju)、電壓(ya)互感器柜(ju)(ju)(ju)、高(gao)壓(ya)電容器柜(ju)(ju)(ju)（GR-1型)、電能計(ji)量(liang)柜(ju)(ju)(ju)（PJ系列)，高(gao)壓(ya)環網柜(ju)(ju)(ju)（HXGN型）等。
