配电柜(箱)分动力配电柜(箱)和照明配电柜(箱)、计量柜(箱),是配电系统的末级设备。配电柜是电动机控制中心的统称。配电柜使用在负荷比较分散、回路较少的场合;电动机控制中心用于负荷集中、回路较多的场合。它们把上一级配电设备某一电路的电能分配给就近的负荷。这级设备应对负荷提供保护、监视和控制。

(1)一级配电设备,统称为动力配电中心。它们集中安装在企业的变电站,把电能分配给不同地点的下级配电设备。这一级设备仅靠降压变压器,故电气参数要求较高,输出电路容量也较大。

(2)二级配电设备,是动力配电柜和电动机控制中心的统称。动力配电柜使用在负荷比较分散、回路较少的场合;电动机控制中心用于负荷集中、回路较多的场合。它们把上一级配电设备某一电路的电能分配给就近的负荷。这级设备应对负荷提供保护、监视和控制。

(3)末级配电设备总称为照明动力配电箱。它们远离供电中心,是分散的小容量配电设备

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.
