Description

An outdoor distribution box structure

technical field

The utility model relates to an outdoor distribution box structure, which belongs to the technical field of distribution boxes.

Background technique

There are many control components and circuits in the distribution box. In the work project, the control components in the electrical cabinet will emit a large amount of heat. If the heat is not dissipated in time, the temperature rise in the electrical cabinet will cause control. The failure of the system will not only make the equipment unable to operate normally, but also bring about a greater safety hazard. The existing distribution box generally provides electrical components inside the distribution box through natural air flow through the opening of the distribution box shell. To cool down, but as an outdoor distribution box, when the weather is bad, rainwater often enters through the opening of the distribution box shell, causing damage to the electrical components in the distribution box, so further improvement is required.
