Cooling, dehumidifying and anti-condensation device for outdoor power cabinets based on intelligent control and online monitoring

technical field

The utility model relates to a cooling and dehumidification and anti-condensation device, in particular to a cooling, dehumidification and anti-condensation device for outdoor power cabinets based on intelligent control and online monitoring.

Background technique

At present, after the power cabinet installed outdoors is exposed to the sun in summer, the temperature inside the power cabinet will increase, thereby accelerating the aging of the electrical appliances in the cabinet; at the same time, because the bottom of the power cabinet is connected with the cable channel , the humid air in the cable trench will enter the power cabinet, and the cabinet of the power cabinet is not tightly sealed, resulting in high humidity inside the cabinet of the power cabinet. When the outdoor temperature changes greatly (such as the temperature difference between day and night), It will cause condensation inside the cabinet of the power cabinet, resulting in problems such as damping, corrosion, and equipment failure of electrical equipment in the cabinet of the power cabinet.

Due to the large number and wide distribution of power cabinets, the daily management and maintenance of power cabinets are often overlooked. However, the general situation today is that a large number of power cabinets have high temperature, high humidity, serious condensation, and equipment corrosion, which seriously affects Safe operation of electrical equipment and reliability of power supply.

1. The heater is used to heat the air inside the cabinet, but it only increases the degree of unsaturation of the water vapor in the air (reduces the relative humidity), but does not discharge the water vapor in the cabinet, and the moisture content of the air in the cabinet does not change. Condensation will still appear in the cabinet when the temperature changes greatly.

2. After the heating temperature in the cabinet increases, it is easier to evaporate the water vapor in the cable trench at the bottom of the cabinet (chimney effect), which increases the moisture content of the air in the cabinet.

3. When the heater is working, its body is very hot, especially when the ambient temperature is high, it will accelerate the aging of the surrounding insulating parts and cables, shorten the service life of the equipment, and affect the safety of operation.

4. In the online state, it is impossible to check and confirm whether the heater is running normally, and it is impossible to know the humidity and condensation in the cabinet. If you want to get the above information in the cabinet, you must inspect one by one, the workload is heavy and the efficiency is low, even so, it is impossible to know its working status in real time.

Therefore, there is an urgent need for a power cabinet device that can overcome the above problems.
