配电柜 强电控 制配电柜

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。 　　

Secondary distribution equipment, it is the power distribution and motor control center.Power distribution cabinets used in load more dispersed, loop less occasion;Motor control center is used to load concentration, circuit more occasions.They turn at the next higher level distribution equipment power allocated to the nearest load of a circuit.This class provides protection, monitoring and control equipment to load.
