Problems solved by technology

Whether the temperature and humidity inside the distribution box are normal or not affects the safe and stable operation of the power system. When the humidity in the box is too high, it will affect the safety of the switch and reduce the service life of the product. However, the existing distribution boxes often do Less than very good dehumidification and cooling

Abstract

The invention discloses a dehumidification device for a distribution box with a vertical low-resistance cooling system, which comprises a main box body and a first storage compartment, and a refrigeration device is arranged in the first storage compartment; a humidity sensor and a temperature sensor are arranged inside the main box body , main controller, exhaust fan, heater and heat exchanger, humidity sensor, temperature sensor, exhaust fan, heater and refrigeration device are all connected with the main controller, heat exchanger includes outer tube and heat exchange tube, heat exchange tube Placed in the outer tube, the two ends of the heat exchange tube are connected with the refrigerant inlet and the refrigerant outlet. A water storage container and a drain pipe are provided, and the top of the water storage container communicates with the drainage funnel. In the present invention, the middle surface of the heat exchange tube is provided with multi-layer and multi-row linear bending heat exchange parts, so that the effect of heat exchange, refrigeration and dehumidification is better, and the water vapor in the humid air is discharged through the drainage funnel after being condensed at the heat exchange tube. Thereby keep the dryness of the air in the main cabinet.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a dehumidification device for a distribution box with a vertical low-resistance cooling system. Background technique [0002] Power distribution box is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment, forms low-voltage distribution equipment. The low-voltage electrical appliances in the distribution box are composed of fuses, AC contactors, residual current action protectors, capacitors and meters. The upper limit of the ambient air temperature shall not exceed 40°C; the average value of the ambient air temperature for 24 hours shall not exceed 35°C; the lower limit of the ambient air temperature shall not be lower than -5°C or -25°C. Whether the temperature and humidity inside the distribution box are normal or not affects the safe and stable operation of the pow...
