How to Deal with Humidity in Power Rooms and Distribution Rooms? Is Installing a Dehumidifier Effective?

In order to conserve space, companies and factories now commonly locate their power distribution rooms underground. However, the issue of moisture prevention remains challenging, especially during the rainy season when there's an abundance of rain and humidity. When moist air enters the high-voltage switchgear, it gets electrolyzed into hydrogen and oxygen ions by the strong electromagnetic field within the switchgear, particularly during the discharge process at cable and copper busbar connections. Once the oxygen ions combine with oxygen molecules in the air, ozone is produced. The instability of ozone can easily disrupt the molecular structure of insulating materials like epoxy resin.

Several days of overcast and rainy weather can always make us feel quite uncomfortable, especially during the south wind season. In many indoor areas, especially those built in basements, the humidity tends to be particularly high. The electrical rooms in basements often have higher humidity. Moist air can easily cause metal equipment in electrical rooms to rust and become damp, leading to short circuits and potentially damaging the power equipment inside the room.

2. Moreover, humid air can damage the control systems of electrical equipment, leading to paralysis of the equipment or safety accidents, with the resulting economic losses being incalculable. Therefore, in the entire power system, power distribution rooms, power stations, machine rooms, substation, and other electrical equipment should be equipped with the corresponding small-scale...DehumidifierStrictly control environmental humidity to achieve energy-saving goals. Moisture-proof and dehumidification.

Additionally, moist air can condense onto the surface of insulating materials, forming crystalline water, which significantly reduces the insulating ability of the material. If dust in the air dissolves in the crystalline water, it can ignite a small electric arc on the surface of the insulating material, further damaging the surface insulation and rendering the insulating properties completely ineffective. Prolonged damage can lead to inter-phase or ground faults in high-voltage switchgear electrical equipment.

Industrial Dehumidifier Principle for Power Distribution Room

The dehumidifier is composed of a compressor, heat exchanger, electric fan, water storage tank, housing, and controller. Its working principle is as follows: moist air is pumped into the machine by the electric fan and passes through the heat exchanger. At this point, water molecules in the air condense into droplets, and the dried air after treatment is discharged from the machine. In this way, the indoor humidity is maintained at an appropriate relative humidity. Consumer group of industrial dehumidifiers: product requirements are not complex, as long as they can meet the dehumidification needs, but they are highly sensitive to prices; these are units with strong capabilities and some scientific research institutions, which have high requirements for the performance of the machine, with price being a secondary consideration.

It is particularly important to minimize moisture entering the high-voltage switchgear to prevent the insulation performance from being compromised. For the moisture-proofing of the high-voltage distribution room, the effective measure is to use dehumidifiers. At the same time, prevent moisture from entering the distribution room to cause significant damage.

Nalanda Industrial Dehumidifiers are equipped with an intelligent humidity control system. Users can automatically control the operation and shutdown of the dehumidifier based on their production needs. Through automatic control, an effective dehumidification function is achieved, thereby reducing the overall operating costs.
