配電箱有什么作用
配(pei)電箱(xiang)是一種用來分配(pei)電能(neng),有較(jiao)高的安全防護等級,能(neng)直觀的顯示電路導(dao)通狀態的電氣(qi)設備(bei)。配(pei)電箱(xiang)正常(chang)運行時(shi)可借(jie)助手動或自動開關,接通或分斷電路,具有體積小、安裝簡便(bian)、技術性能(neng)特(te)殊、位(wei)置(zhi)固(gu)定、配(pei)置(zhi)功能(neng)獨特(te)、不受場地限制等等特(te)點。
控制箱和配電箱的區別
配電箱是一個小型的電源分配箱,內部包含電源開關和保險裝置。結構比較簡單,多用于終端電源分配。配電箱是供電系統中的末端配電設施,一個配電箱可以是一個電源進線和多個供電輸出回路,從配電箱引出供電輸出回路至各個用電負荷,由于配電箱品牌產品的(de)體積較小(xiao),不能放入大型(xing)配(pei)電(dian)(dian)(dian)設備,所(suo)以配(pei)電(dian)(dian)(dian)箱(xiang)(xiang)的(de)容量都不大,一(yi)般4-8個小(xiao)負荷用一(yi)個配(pei)電(dian)(dian)(dian)箱(xiang)(xiang),配(pei)電(dian)(dian)(dian)箱(xiang)(xiang)布置在供電(dian)(dian)(dian)負荷的(de)中心地帶,用電(dian)(dian)(dian)纜或者電(dian)(dian)(dian)線將電(dian)(dian)(dian)送到負荷。
控制(zhi)(zhi)(zhi)(zhi)(zhi)箱是用各類建筑物內(nei)外,作(zuo)為動(dong)(dong)(dong)力(li)、照明配電(dian)及(ji)電(dian)動(dong)(dong)(dong)機控制(zhi)(zhi)(zhi)(zhi)(zhi)之(zhi)用,適合室內(nei)掛墻、戶外落地安裝的配電(dian)設(she)備。主要(yao)用于消防(fang)水泵(beng)控制(zhi)(zhi)(zhi)(zhi)(zhi)、潛水泵(beng)控制(zhi)(zhi)(zhi)(zhi)(zhi)、消防(fang)風(feng)機控制(zhi)(zhi)(zhi)(zhi)(zhi)、風(feng)機控制(zhi)(zhi)(zhi)(zhi)(zhi)、照明配電(dian)控制(zhi)(zhi)(zhi)(zhi)(zhi)等使(shi)用,控制(zhi)(zhi)(zhi)(zhi)(zhi)方式有直接啟(qi)(qi)動(dong)(dong)(dong)控制(zhi)(zhi)(zhi)(zhi)(zhi)、星三角降(jiang)壓(ya)啟(qi)(qi)動(dong)(dong)(dong)控制(zhi)(zhi)(zhi)(zhi)(zhi)、自(zi)藕(ou)降(jiang)壓(ya)啟(qi)(qi)動(dong)(dong)(dong)控制(zhi)(zhi)(zhi)(zhi)(zhi)、變頻器啟(qi)(qi)動(dong)(dong)(dong)控制(zhi)(zhi)(zhi)(zhi)(zhi)、軟啟(qi)(qi)動(dong)(dong)(dong)控制(zhi)(zhi)(zhi)(zhi)(zhi)等各種控制(zhi)(zhi)(zhi)(zhi)(zhi)方式,還可使(shi)用隔離(li)開關、熔(rong)斷器式開關作(zuo)為隔離(li)分斷點。
配電箱規格型號有哪些
配電箱型(xing)(xing)號有(you)很多,一般不同的廠(chang)家都有(you)自己的型(xing)(xing)號。常見的國產型(xing)(xing)號有(you)MLS、GCS、GCKGGD等,國外廠(chang)家ABB有(you)MD190,MNS,ArTu、Blokset、8PT等等,具體實(shi)際規格型(xing)(xing)號以廠(chang)家為準,暫時沒有(you)國標可以規范(fan)。
配電箱有哪些安裝方法
配(pei)電(dian)(dian)(dian)(dian)箱可(ke)(ke)以掛在墻上(shang),也可(ke)(ke)以嵌入(ru)墻內(nei)。掛在墻上(shang)時(shi),應采(cai)用開腳螺栓固定,對于較小的配(pei)電(dian)(dian)(dian)(dian)箱,也可(ke)(ke)在安裝處(chu)預(yu)(yu)埋好木磚(zhuan),然后用木螺釘在木磚(zhuan)處(chu)固定配(pei)電(dian)(dian)(dian)(dian)箱或配(pei)電(dian)(dian)(dian)(dian)板。嵌入(ru)墻內(nei)時(shi),預(yu)(yu)留孔洞應比配(pei)電(dian)(dian)(dian)(dian)箱的長和寬各大(da)20mm左右,這樣可(ke)(ke)以方便(bian)添加混凝土固定。
