配電柜（箱）分動(dòng)力配電柜（箱）和照明配電柜（箱）、計(jì)量柜（箱），是配電系統(tǒng)的末級(jí)設(shè)備。配電柜是電動(dòng)機(jī)控制中心的統(tǒng)稱。配電柜使用在負(fù)荷比較分散、回路較少的場(chǎng)合；電動(dòng)機(jī)控制中心用于負(fù)荷集中、回路較多的場(chǎng)合。它們把上一級(jí)配電設(shè)備某一電路的電能分配給就近的負(fù)荷。這級(jí)設(shè)備應(yīng)對(duì)負(fù)荷提供保護(hù)、監(jiān)視和控制。
（1）一級(jí)配電設(shè)備，統(tǒng)稱為動(dòng)力配電中心。它們集中安裝在企業(yè)的變電站，把電能分配給不同地點(diǎn)的下級(jí)配電設(shè)備。這一級(jí)設(shè)備僅靠降壓變壓器，故電氣參數(shù)要求較高，輸出電路容量也較大。
（2）二級(jí)配電設(shè)備，是動(dòng)力配電柜和電動(dòng)機(jī)控制中心的統(tǒng)稱。動(dòng)力配電柜使用在負(fù)荷比較分散、回路較少的場(chǎng)合；電動(dòng)機(jī)控制中心用于負(fù)荷集中、回路較多的場(chǎng)合。它們把上一級(jí)配電設(shè)備某一電路的電能分配給就近的負(fù)荷。這級(jí)設(shè)備應(yīng)對(duì)負(fù)荷提供保護(hù)、監(jiān)視和控制。
（3）末級(jí)配電設(shè)備總稱為照明動(dòng)力配電箱。它們遠(yuǎn)離供電中心，是分散的小容量配電設(shè)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.
