Two Dehumidification Solutions for Power Distribution Cabinet

As for dehumidification solutions, you can choose an enclosure heater or electrical cabinet dehumidifier for power distribution. Today, this article will introduce the two dehumidification solutions from reason, their comparison, and so on.

1. Why does Power distribution cabinet need dehumidification solutions?

Electric power distribution cabinets, such as terminal boxes, mechanism boxes, complete sets of switch cabinets, distribution cabinets, etc., are easily affected by high humidity environments due to the small spacing between equipment. High humidity can lead to problems such as reduced insulation performance, risk of electrical flashover, equipment rust, and mold growth.

To protect against these potential risks, dehumidification solutions are needed. Degradation of insulation performance may cause electrical equipment failure, electrical flashover is a serious safety hazard, and corrosion and mold growth of equipment will affect its reliability and service life. Through dehumidification measures, humidity can be effectively reduced to prevent moisture absorption of insulation materials, electrical flashover, corrosion of metal parts, and mold generation, thereby maintaining the normal operation of equipment and the safety and reliability of the power system. This helps ensure efficient, stable and long-lasting operation of electrical equipment in humid environments.

2. Dehumidification Solutions for Power Distribution Cabinet

Dehumidification solutions – Enclosure heater

The dehumidification solution of installing an enclosure heater is to prevent condensation and moisture problems caused by excessive humidity by increasing the temperature inside the power distribution cabinet. Humidity is the amount of water vapor in the air, while temperature is related to the amount of water vapor the air can hold. By increasing the temperature, the relative humidity decreases, thereby maintaining a dry environment around electrical equipment.

Enclosure Heaters are often equipped with humidity control systems that automatically start and stop based on a set humidity threshold. When the humidity reaches the set value, the heater starts to increase the internal temperature; once the humidity drops to the appropriate level, the heater automatically stops working. This mode of operation ensures that the right amount of heating is provided in a timely manner under high humidity conditions to maintain humidity at an acceptable level.

Dehumidification solutions – Intelligent cabinet dehumidifers

Intelligent cabinet dehumidifiers achieve the goal of reducing humidity by absorbing moisture from the air, condensing water vapor, and expelling the moisture out of the power distribution cabinet. This device can control humidity more accurately and perform dehumidification operations according to actual needs by starting and stopping. This working principle helps maintain a dry environment around the device.

Smart cabinet dehumidifiers are equipped with humidity control and can start and stop automatically. When the humidity exceeds the set value, the smart dehumidifier automatically starts to reduce the internal humidity of the electrical distribution cabinet through the process of moisture absorption and drainage. Once the humidity reaches the right level, the dehumidifier automatically stops working. This mode of operation is designed to minimize humidity while ensuring efficient use of energy.

Comparison between enclosure heater and electrical cabinet

Install an enclosure heater

This enclosure heater dehumidification solution has the following advantages:

Simple and effective: Installing a heater is a simple and effective solution, especially suitable for scenarios with less stringent humidity control requirements.
Easy to operate: Heaters usually have automatic control functions that do not require manual intervention and are quite easy to operate.
Reliable Humidity Control: By raising the temperature, humidity around electrical equipment can be reliably maintained at the right level, preventing condensation and moisture problems.

Industrial cabinet dehumidifier
Using an industrial smart cabinet dehumidifier to solve moisture problems has the following advantages:

Fine humidity control: Intelligent dehumidifiers can provide more precise humidity control and are suitable for scenarios with high requirements for humidity control.
Efficient energy utilization: Because smart dehumidifiers only start when needed, they can use energy more effectively and improve energy efficiency.
Automated operation: Smart dehumidifiers equipped with humidity control functions can automatically respond to humidity changes without manual intervention, making operations more intelligent and convenient.

From the above comparison, which is dehumidification solution better for you?

Cost: Heaters are relatively simple and low cost. Smart dehumidifiers may have some additional costs in equipment and installation but may pay for themselves in the long run through energy cost savings.

Humidity control accuracy: Smart dehumidifiers can provide more precise humidity control and are suitable for high-demand scenarios. Heaters are relatively crude in humidity control.

Energy efficiency: Smart dehumidifiers only run when needed, can use energy more efficiently, and are relatively more energy-saving. Heaters can be relatively inefficient in their use of energy.

To get a better dehumidification solution, you need to consider your real situation too.

3.Conclusion

Cabinet equipment such as terminal boxes, mechanism boxes, complete sets of switch cabinets, and distribution cabinets are crucial components in power substations. The components inside this equipment are extremely sensitive to humidity. In these devices, excessive humidity can cause a variety of problems. First, the insulation level of internal components may be affected, increasing the risk of electrical equipment failures such as leakage and arcing. Secondly, high-humidity environments are prone to mold growth, which may adversely affect the reliability and stability of the equipment. In addition, excessive humidity will cause metal parts to rust, which will affect electrical contacts and conductive properties, thus threatening the safe operation of the equipment.

To solve the problems caused by this humidity, Blue Jay developed and launched the DH series intelligent semiconductor condensing dehumidifier, which is specially used for electrical distribution cabinet. The application of this innovative technology has achieved remarkable results in the market.
