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 distribution box dehumidification device with a vertical low-resistance cooling system. The device comprises a main box body and a first placement warehouse, the first placement warehouse is configured above the top panel of the main box body, and a refrigeration device is arranged inside the first placement warehouse. The main box body is internally equipped with a humidity sensor, a temperature sensor, a main controller, an exhaust fan, a heater and a heat exchanger. The humidity sensor, the temperature sensor, the exhaust fan, the heater and the refrigeration device are connected with the main controller. The heat exchanger includes an outer tube and a heat exchange tube, the heat exchange tube is arranged inside the outer tube, the two ends of the heat exchange tube are respectively connected with a refrigerant inlet and a refrigerant outlet, and the middle surface of the heat exchange tube is provided with a multi-layer and multi-column linear bent heat exchange member. According to the invention, as the middle surface of the heat exchange tube is provided with the multi-layer and multi-column linear bent heat exchange member, the heat exchange, refrigeration and dehumidification effects are better, water vapor in moist air is cooled and condensed at the heat exchange tube and then drained by a drainage funnel, and thus, the air in the main box body is kept dry.

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...
