配電櫃(箱)分動力配電櫃(箱)和照明配電櫃(箱)、計量櫃(箱),是配電系統的末級設備。配電櫃是電動機控制中心的統稱。配電櫃使用在負荷比較分散、回路較少的場合;電動機控制中心用于負荷集中、回路較多的場合。它們把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。

(1)一級配電設備,統稱爲動力配電中心。它們集中安裝在企業的變電站,把電能分配給不同地點的下級配電設備。這一級設備僅靠降壓變壓器,故電氣參數要求較高,輸出電路容量也較大。

(2)二級配電設備,是動力配電櫃和電動機控制中心的統稱。動力配電櫃使用在負荷比較分散、回路較少的場合;電動機控制中心用于負荷集中、回路較多的場合。它們把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)末級配電設備總稱爲照明動力配電箱。它們遠離供電中心,是分散的小容量配電設備

Distribution cabinet(box) distribution cabinet(box) power distribution cabinet(box) and lighting distribution cabinet(box), measuring cabinet(box), is the distribution system's final equipment. The power distribution cabinet is the collective name of the motor control center. The distribution cabinet is used in situations where the load is relatively dispersed and the circuit is less; The motor control center is used for situations where the load is concentrated and there are more circuits. They distribute the electrical energy of a circuit in the upper distribution equipment to the nearest load. This type of equipment should provide protection, monitoring and control of the load.
(1) Primary distribution equipment, collectively referred to as power distribution center. They are centrally installed in enterprise substations and distribute electrical energy to lower-level distribution equipment in different locations. This level of equipment only depends on buck Transformers, so the electrical parameters are required to be high, and the output circuit capacity is also large.
(2) Secondary distribution equipment is the collective name for power distribution cabinets and motor control centers. Power distribution cabinets are used in situations where the load is relatively dispersed and the circuit is less; The motor control center is used for situations where the load is concentrated and there are more circuits. They distribute the electrical energy of a circuit in the upper distribution equipment to the nearest load. This type of equipment should provide protection, monitoring and control of the load.
(3) The last stage distribution equipment is collectively referred to as the lighting power distribution box. They're far away from the power center. They're scattered, small-capacity electrical equipment.
