The invention relates to the technical field of power supply equipment and discloses a dustproof and dampproof power distribution cabinet which comprises a power distribution cabinet body, wherein aninstallation plate is fixedly arranged in the power distribution cabinet body, a power
distributor is fixedly arranged on the front side of the installation plate, a partition plate arranged on the front side of the installation plate is fixedly arranged on one side of the power
distributor, a base is fixedly connected to the bottom end of the power distribution cabinet body, a venting hole is formed in the top of one side of the base, a dampproof layer is arranged at the bottom end of an inner cavity of the base, a
servo motor is fixedly arranged at the top end of the inner cavity of the base, and an outer wall of the
servo motor is fixedly sleeved in the box body at the top end of the inner cavity of the base. The dustproof dampproof power distribution cabinet is provided with the base,the venting hole, the dampproof layer, the
servo motor and a fan, so that air around the base can be circulated; by means of air circulation,
moisture near the base can be prevented from increasing; as the
moisture near the base is reduced, dehumidifying and dampproof effects are achieved, and the power distribution cabinet is ensured to be prevented from the damp phenomenon.
