Electrical equipment manufacturers: what are the precautions for the installation of distribution box?

安装配电箱有相应的规范需要大家遵循，接下来我们成套电气厂家就来说说安装配电箱的注意事项有哪些。

There are corresponding specifications for the installation of distribution box that we need to follow. Next, we will talk about the precautions for the installation of distribution box.

（1）施工用电配电系统应设置总配电箱、分配电箱、开关箱，并按照“总-分-开”顺序作分级设置，并形成“三级配电”模式。

(1) The main distribution box, distribution box and switch box shall be set in the construction power distribution system, which shall be set in different levels according to the sequence of "main distribution open" and form a "three-level distribution" mode.

（2）施工用配电系统各配电箱、开关箱的安装位置要合理。总配电箱要尽量靠近变压器或外电源处，以便电源的引入。分配电箱应尽量安装在用电设备或负荷相对集中的中 心地带，确保三相负荷保持平衡。开关箱安装的位置应视现场情况和工况尽量靠近其控制的用电设备。

(2) The installation position of each distribution box and switch box of construction power distribution system shall be reasonable. The main distribution box should be close to the transformer or external power supply as far as possible to facilitate the introduction of power supply. The distribution box shall be installed in the central area where the electric equipment or load is relatively concentrated as far as possible to ensure the balance of three-phase load. The installation position of the switch box shall be close to the electrical equipment controlled by it as far as possible according to the site conditions and working conditions.

（3）保证临时用电配电系统三相负荷平衡，施工现场的动力用电和照明用电应形成两个用电回路，动力配电箱与照明配电箱应该分别设置。

(3) To ensure the three-phase load balance of the temporary power distribution system, the power and lighting power on the construction site should form two power circuits, and the power distribution box and lighting distribution box should be set separately.
                   

（4）施工现场所有用电设备必须有各自的专用的开关箱。

(4) All electrical equipment on the construction site must have their own special switch box.

（5）各级配电箱的箱体和内部设置必须符合规定，开关电器应标明用途，箱体应统一编号。停止使用的配电箱应切断电源，箱门上锁。成套电气厂家固定式配电箱应设置围栏，并有防雨防砸措施。

(5) The cabinet and internal setting of distribution boxes at all levels must comply with safety regulations. The purpose of switchgear shall be indicated and the cabinet shall be numbered uniformly. The power supply shall be cut off and the door shall be locked when the distribution box is out of service. The fixed distribution box of complete electrical manufacturer shall be provided with fence and rain proof and smashing proof measures.

（6）配电箱与配电柜的区别。根据GB/T20641-2006 《低压成套开关设备和控制设备空壳体的一般要求》

(6) The difference between distribution box and distribution cabinet. According to GB / t20641-2006 General requirements for empty shells of low voltage switchgear and controlgear assemblies

配电箱一般是家庭用的，而配电柜则多用在集中供电中，比如说工业用电和建筑用电等，配电箱和配电柜都属于成套设备，配电箱属于低压成套设备，配电柜有高压有低压。

The distribution box is generally used for household use, while the distribution cabinet is mostly used in centralized power supply, such as industrial power and construction power. The distribution box and the distribution cabinet belong to complete sets of equipment, the distribution box belongs to low-voltage complete sets of equipment, and the distribution cabinet has high voltage and low voltage.
