Anti-condensation equipment and electrical control cabinet thereof

Abstract

The invention discloses anti-condensation equipment and an electrical control cabinet thereof, and belongs to the field of anti-condensation electrical control cabinets. The anti-condensation equipment is characterized in that a condensation box with a condensation assisting ball is additionally arranged at the wind inlet of a cabinet body, external air is guided into an air inducing condensation cavity formed by the condensation assisting ball and a flow guide cover, and due to the fact that the temperature difference exists between the condensation assisting ball and the air and between the flow guide cover and the air, water vapor in the air is attached to the end surfaces ofthe flow guide cover and the condensation assisting ball to be condensed and guided into a liquid storage box through the arc-shaped end surfaces of the flow guide cover and the condensation assisting ball, so that the water vapor is effectively removed, the dehumidification cotton layer at the inner end is matched to dehumidify the air, and the air is guided into the cabinet body after making contact with the low-temperature condensation assisting ball to be cooled so as to improve the cooling effect on the cabinet body; and the refrigeration balls filled with refrigerants are arranged on the inner sides of the condensation assisting balls, in the high-temperature environment, the heat drainage pieces deform to guide the cooling liquid in the condensation assisting balls into the refrigeration balls, and the refrigerants and the cooling liquid are fused to absorb heat and refrigerate, so that the refrigeration effect is improved, and the temperature difference is increased to facilitate pre-condensation.

Description

[0001] The original application number of this divisional application is 202111188050.3, the application date is October 12, 2021, and the name is: an outdoor anti-condensation heat dissipation and dehumidification electrical control cabinet. technical field [0002] The invention relates to the field of electrical control cabinets, and more specifically, to an anti-condensation device and an electrical control cabinet thereof. Background technique [0003] The electrical control cabinet is to assemble switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen width according to the wiring requirements. and the safety of surrounding equipment. During normal operation, the circuit can be connected or disconnected by manual or automatic switch, and the circuit can be cut off or alarmed by means of protective electrical appliances in case of failure or abnormal operation. Various parameters in operati...

Problems solved by technology

It will generate a lot of heat during long-term operation, especially for products with frequency converters, which will generate more heat, and it is easy to make the internal temperature of the electrical control cabinet reach more than 40 degrees, and the components themselves are also very sensitive to high temperatures. Sensitive, once the temperature inside the electrical control cabinet is higher than 40°C for a long time, it will seriously affect the operation stability and service life of our power distribution equipment

[0004] Existing electrical control cabinets generally take heat dissipation measures, the most common is to set cooling holes that communicate with the outside world, but because outdoor electrical control cabinets are exposed to the natural environment, moisture in the outside air will enter the electrical control cabinet, resulting in The humidity in the cabinet is high. At the same time, in high temperature weather, the air humidity is high. Due to the large temperature difference between the electrical control cabinet and the external environment, the moisture in the air is easy to condense into dew on the surface of the electrical components and gather into water droplets. To a certain extent, it will cause corrosion to the electrical components in the cabinet, which will easily cause problems such as circuit short circuit and electric leakage.
