配电箱注意事项
(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 total distribution box, distribution box and switch box should be set up in the construction power distribution system, and graded according to the order of "total-separate-open", and a "three-level distribution" mode should be formed.
(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 distribution boxes and switch boxes in construction distribution system should be reasonable. The main distribution box should be as close as possible to the transformer or external power supply for the introduction of power supply. Distribution box should be installed in the central area of power equipment or relatively concentrated load to ensure the balance of three-phase load. The position of switchbox installation should be as close as possible to the electrical equipment controlled by the switchbox 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) Guarantee the three-phase load balance of the temporary power distribution system. The power and lighting power in the construction site should form two power circuits. The power distribution box and the lighting distribution box should be set up 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 at the construction site must have their own special switchboxes.
(5)各级配电箱的箱体和内部设置必须符合安全规定,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。固定式配电箱应设置围栏,并有防雨防砸措施。
(5) The boxes and internal installations of distribution boxes at all levels must conform to safety www.yijingguan.cnwww.pingdifengtou.cnwww.xingtaibaojie.com.cn www.diandongmenn.com.cnwww.daishiganzaoj.cnwww.shidiaopenqua.cnregulations. Switching appliances should be marked for use and the boxes should be uniformly numbered. The power supply should be cut off and the door of the distribution box should be locked. Fixed distribution boxes should be fenced with rain and smash-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) Distribution box and distribution cabinet difference. According to GB/T 206441-2006 "General Requirements for Hollow Shell of Low Voltage Switchgear and Control Equipment"
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。
Distribution boxes are generally used at home, while distribution cabinets are mostly used in centralized power supply, such as industrial power and construction power. Distribution boxes and distribution cabinets belong to complete sets of equipment, distribution boxes belong to low-voltage complete sets of equipment, distribution cabinets have high voltage and low voltage.
