As the terminal control device of the entire power system, the importance of the distribution box is self-evident, especially the safety performance of the distribution box has attracted everyone's attention. Not only the quality of the distribution box itself, but also some points that need to be paid attention to when the distribution box is used on the construction site, will also affect the safety performance of the distribution box.

1. Hierarchical power distribution

In many construction sites today, the form of hierarchical power distribution is implemented. Generally, a power distribution room is set up, and a lower-level distribution box is set through the power distribution room to realize the power supply of the construction site.

2. Placement of distribution box

The main distribution box should be installed in a position closer to the power supply, and the graded distribution box should be installed in a place with a lot of electricity, which is more convenient for the realization of power distribution. However, it should be noted that the distance between the graded distribution box and the switch box should not be too far, and the distance between the switch box and the electrical equipment should not be too far.

3. Working environment

The working environment of the distribution box is very important, and it should be placed in a ventilated, dry place where the temperature does not change much. It is not difficult to imagine that it is definitely not acceptable to place charged things in a humid environment. Moreover, in the working environment of the distribution box, there should be no flammable and dangerous gases, and there should not be too much liquid. A good working environment must be maintained.

4. Materials,

In construction sites with relatively high working pressure, materials with better insulation or higher protection levels should be selected, and safety is the first priority.

5. Wire setting

Whether it is a distribution box or a switch box, their wires should be prevented from being under the box, and entering the box from other places is strictly prohibited.
