电表箱箱体设计
Design of ammeter box box
新型电缆分支箱的上述优点皆源于纤维增强聚酯材料本身的特性。此外在箱体设计方面也赋予这种新型电缆分支箱许多不同于金属箱体的特点：
The advantages of the new cable branch box are all derived from the properties of the fiber reinforced polyester material itself. In addition, the cabinet design also endows this new cable branch box with many different characteristics from the metal box.
1、用通风组件对箱体通风，防止产生过量蒸馏水
1. Ventilation box is used to ventilate the box to prevent excessive distilled water.
在箱体柜门、背板的下端及上端，顶板、柜门和背板之间留有通风组件，借助电气元件产生的热量，可对箱体内空间做去湿处理，既可防止箱体内金属件的锈蚀，也可防止漏电流发生。
In the cabinet door, the lower end of the back plate and the upper end, the roof, the cabinet door and the back plate between the ventilation components, with the help of the heat generated by electrical components, can do dehumidification of the cabinet space, can prevent the corrosion of metal parts in the cabinet, but also prevent leakage of current.
2、隔绝土壤湿度
2. Isolation of soil moisture
带底座的电缆分支箱，通过在底座中充入细沙并将底座埋入地表下一定深度，使土壤中上升的湿气不进入箱体内。
The cable branch box with a base fills the base with fine sand and buries the base at a certain depth under the ground, so that the moisture rising in the soil does not enter the box.
3、组合式设计使得安装简便
3. Combined design makes installation easy.
组合式设计不仅使得安装简便，而且很容易替换箱体部件，简化备件保管。
The combined design not only makes the installation easy, but also easily replace the box parts and simplify the storage of spare parts.
