　　The distribution box represents the voltage of the bus. There is a door in front of the distribution box. When the door opens, all the equipment in the distribution box is exposed for easy maintenance. The distribution box adopts localization design, the structure is compact, the maintenance is convenient, and the combination of line scheme is flexible. The distribution box is equipped with air circuit breakers and fuses as short circuit protection. Contactors and thermal relays are also equipped. The front door of the box can be equipped with operation buttons and indicators.

　　(1)一等配电设备统称为配电核心。它们集中安装在企业变电站中，并将电能分配给不同地点的低级配电设备。这个级别的设备只取决于步骤，降压变压器的电气参数较高，输出电路容量也较大。

　　(1) such distribution equipment is collectively referred to as the distribution core. They are concentrated in enterprise substations and distribute electricity to low-level distribution equipment in different locations. This level of equipment only depends on the steps, the voltage transformer has higher electrical parameters, and the output circuit capacity is also large.

　　(2)二次配电设备是配电柜和电机控制核心的总称创盈。配电柜适用于负载分散、电路少的场合;在负载集中、电路多的情况下，采用电机控制核心。它们分配上层分布电路的电能。

　　(2) Secondary distribution equipment is the general name of distribution cabinet and motor control core. The distribution cabinet is suitable for the field station with scattered load and less circuits; in the case of concentrated load and many circuits, the motor control core is adopted. They distribute the electricity of the upper distribution circuit.
