                      中國人民電器介紹低壓成套開關設備的分類

                      額定電壓為1000V及以下的低壓成套開關設備一般分為三類:
                          (1) -級配電設備統稱為動力配電中心,集中安裝在企業的變電站,將電能分配給安裝在不同地點的下級配電設備,個別重要負荷可直接由一級配電設備供電。由于設備緊靠降壓變壓器,對設備供電的電氣參數要求較高,輸出電路容量較大。
                          (2)二級配電設備為動力配電柜和電動機控制中心的統稱。動力配電柜使用于負荷比較分散、回路比較少的場合,電動機控制中心使用于負荷集中、回路較多的場合,將上一級配電設備某一電路的電能分配給就近的負荷。這級設備應對負荷提供保護、監視和控制。
                          (3)末級配電設備統稱為照明配電箱,它是遠距離供電中心分散的小容量配電設備,對小容量負荷進行保護、監視和控制。
                          按設備的結構特征分,可分為固定面板式、封閉式和抽出式成套開關設備三大類。
