Description

Technical Field

[0001] The utility model belongs to the technical field of distribution boxes, and in particular relates to a dehumidification device for a distribution box. Background Art

[0002] A distribution box is a device used for switching, controlling or protecting in power generation, transmission, distribution, energy conversion and consumption in power systems. It occupies a very important position in the entire power industry. It has the characteristics of small size, easy installation, special technical performance, fixed position, unique configuration function, no site restrictions, widespread application, stable and reliable operation, high space utilization, small footprint and environmental protection.

[0003] At present, the distribution box in the prior art is easily affected by the external environment during long-term operation, causing the internal air humidity to increase, so that humid air gathers inside the distribution box, which can easily cause short circuit or even damage to the power components inside the distribution box. The moisture-proof and dehumidification protection devices of the existing distribution boxes are mostly arranged in the corners on the inside of the distribution box. The moisture absorption is not comprehensive enough and can only absorb the surrounding water vapor. The water vapor away from the protection device will still damage the internal instruments. In addition, the desiccant is troublesome to replace and is not convenient for long-term moisture absorption.

[0004] Based on this, the utility model designs a dehumidification device for a distribution box to solve the above problems. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. When the utility model is in use, the sealing covers on the left and right dehumidification components are removed, and then the exhaust fan in the dehumidification component on one side is started. The humid air in the box is sucked out through the rotation of the exhaust fan and the moisture is adsorbed through the dehumidifier in the breathable box, while the outside air enters the box through the dehumidification chamber on the dehumidification component on the other side, and the air is flow-dehumidified to make the dehumidification range more comprehensive. At the same time, the outside air will pass through the recyclable dehumidifier placed in the other breathable box to dry the outside air before entering the box, so that the incoming gas is also kept in a dry state, with a good moisture-proof and dehumidification effect to ensure the normal operation of the internal power components;

[0016] 2.
