[0002] The distribution box is a device for distributing electric power, usually composed of switching devices, measuring instruments, protective appliances and auxiliary devices, installed on a closed or semi-closed metal cabinet or screen. It is mainly a control center that reasonably distributes electric energy of various components in the power supply circuit. It can reliably receive the power supply at the upper end, correctly feed the load power, and also can directly display the circuit conduction state, facilitate the opening and closing operation of the circuit, and has a high safety protection level.

[0003] The switching devices, measuring instruments, protective appliances and other devices in the distribution box will generate heat during operation. If the heat cannot be dissipated in time, the internal temperature will rise, affecting the performance and service life of the electrical components, and even causing failure or damage. High temperature may cause electrical fire and other safety accidents. Setting a heat dissipation window helps to control the temperature within a safe range, ensuring the safe and stable operation of the distribution box and the entire electrical system. Natural ventilation and heat dissipation window can promote the natural exchange of air, allowing external cold air to enter the distribution box and carry away internal heat, thereby improving the heat dissipation efficiency and reducing the internal temperature of the distribution box.

[0004] However, in rainy weather, the wind and rain are easy to flow into the distribution box through the heat dissipation window, which may cause short circuit or damage to the electronic components and devices inside the box, thereby affecting the normal operation of the equipment.
