    KYN28A-12金屬鎧(kai)裝(zhuang)(zhuang)中置(zhi)(zhi)(zhi)式封閉開(kai)(kai)關設備(bei)，系3.6~12千伏(fu)三相(xiang)交(jiao)流50Hz單(dan)母(mu)線(xian)及單(dan)母(mu)線(xian)分段系統(tong)的(de)成套配電(dian)(dian)(dian)(dian)(dian)(dian)裝(zhuang)(zhuang)置(zhi)(zhi)(zhi)。本開(kai)(kai)關柜滿足IEC298、GB3906等(deng)標(biao)準要求。具(ju)有防止帶(dai)負(fu)荷推拉斷路(lu)器(qi)(qi)手車、防止誤(wu)分合斷路(lu)器(qi)(qi)、防止接地開(kai)(kai)關處在封合位置(zhi)(zhi)(zhi)時(shi)關合斷路(lu)器(qi)(qi)、防止誤(wu)入(ru)帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)隔室、防止在帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)時(shi)誤(wu)合接地開(kai)(kai)關的(de)聯(lian)鎖(suo)功能。既可配用(yong)ABB公司的(de)VD4真空斷路(lu)器(qi)(qi)，又可配用(yong)國(guo)內(nei)產VS1（ZN63）等(deng)真空斷路(lu)器(qi)(qi)，實為一種(zhong)性能優越的(de)配電(dian)(dian)(dian)(dian)(dian)(dian)裝(zhuang)(zhuang)置(zhi)(zhi)(zhi)。此產品主要用(yong)于發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)廠(chang)、中小型發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機送(song)電(dian)(dian)(dian)(dian)(dian)(dian)、工礦企(qi)事業配電(dian)(dian)(dian)(dian)(dian)(dian)以(yi)及電(dian)(dian)(dian)(dian)(dian)(dian)力系統(tong)的(de)二次(ci)變電(dian)(dian)(dian)(dian)(dian)(dian)所的(de)受(shou)電(dian)(dian)(dian)(dian)(dian)(dian)、送(song)電(dian)(dian)(dian)(dian)(dian)(dian)及大型高(gao)壓電(dian)(dian)(dian)(dian)(dian)(dian)動機起動等(deng)，實行控制保(bao)護、監測之用(yong)。

    該產(chan)品(pin)經(jing)過改進設計后還可適用于(yu)海(hai)洋石油平臺(tai),滿(man)足海(hai)洋"防(fang)鹽霧、防(fang)霉(mei)變、防(fang)潮(chao)濕"三防(fang)要求(qiu)。

主要結構特點：

1、柜體(ti)外(wai)殼選用進口敷鋁鋅板(ban)，抗氧(yang)化，抗腐蝕；

2、手車(che)采用中置式結構，確保了動(dong)靜觸頭的(de)配合，手車(che)互換性(xing)好；

3、采(cai)用關門操作(zuo)，具有(you)可(ke)靠的機械聯鎖機構，滿足(zu)“五防(fang)”要求；

4、電纜(lan)室(shi)空(kong)間大(da)，電纜(lan)安裝高(gao)度大(da)于(yu)800mm，并可安裝18根單芯電纜(lan)；

 5、可移(yi)開部分（手車）采用落(luo)地式周轉小(xiao)車，靈活、可靠、檢修方(fang)便；

6、手車(che)采用加強絕(jue)緣，從而(er)避免相間(jian)發生擊穿的可能性(xing)；

7、各隔室(shi)均設有(you)瀉壓通(tong)道，可以(yi)經受內部故障電(dian)弧，各隔室(shi)間采用金屬隔板，從(cong)而避免了(le)事故的擴大蔓延。

8、開(kai)關柜可滿足大容量的(de)要(yao)求，可達到(dao)額定(ding)電流5000A，開(kai)斷50kA。
