Description

Technical Field

[0001] The utility model belongs to the technical field of distribution boxes, in particular to a moisture-proof distribution box. Background Art

[0002] The massive parameters on the distribution box data generally constitute low-voltage electrical wiring, which requires the switchgear, measuring instruments, protective electrical appliances and auxiliary equipment to be assembled in a closed or semi-closed metal cabinet or on a screen to form a low-voltage distribution box. During normal operation, the circuit can be connected or disconnected with the help of a manual or automatic switch. When the distribution box is used in the rainy season or in a humid environment, water vapor in the environment will enter the interior through the heat dissipation ports on both sides of the distribution box, which can easily cause moisture inside the distribution box. Once the inside of the box is in a humid state, the metal fittings inside the box are prone to rust, and tripping will often occur, which may seriously cause a fire. For this reason, the present application proposes a moisture-proof distribution cabinet. Utility Model Content
