To save space, nowadays enterprises and factories all arrange the distribution rooms underground, but the problem of moisture-proofing is hard to avoid. Especially during the rainy season, there is a lot of rain and the humidity is high. When moist air enters a high-voltage switch cabinet, it will be electrolyzed into hydrogen ions and oxygen ions by the strong electromagnetic field inside the switch cabinet, especially during the discharge process at the connection between cables and copper bars. Once oxygen ions combine with oxygen molecules in the air, ozone is produced. The instability of ozone can easily damage the molecular structure of insulating materials such as epoxy resin.

The reasons for installing industrial dehumidifiers in the distribution room

Several consecutive days of rainy weather always make us feel very uncomfortable, especially in the south or on windy days. In many places indoors, the moisture flows back very seriously and the humidity is often very high. Some distribution rooms built in basements have relatively high humidity. Damp air can easily cause the metal equipment in the distribution room to rust due to moisture, which may lead to short circuits and damage to the electrical equipment in the machine room.

Moreover, damp air can also damage the control systems of power equipment, leading to equipment paralysis or safety accidents, and the resulting economic losses are incalculable. Therefore, in the entire power system, power equipment such as distribution rooms, power stations, machine rooms, and substations need to be equipped with corresponding small dehumidifiers in the substation and distribution room to strictly control the environmental humidity, thereby achieving the purpose of energy conservation. Moisture-proof and dehumidification.

In addition, moist air will condense into crystalline water on the surface of insulating materials, which will greatly reduce the insulating capacity of the insulating material surface. If the dust in the air dissolves in the crystalline water, it will ignite a small electric arc on the surface of the insulating material, further damaging the surface insulation of the insulating material, and the insulating performance of the insulating material will completely disappear. Long-term damage has led to phase-to-phase or ground short circuit accidents in the electrical equipment of high-voltage switch cabinets.

The principle of industrial dehumidifiers in distribution rooms

A dehumidifier is composed of a compressor, a heat exchanger, an electric fan, a water reservoir, a casing and a controller. Its working principle is as follows: Wet air is pumped into the machine by an electric fan and passes through a heat exchanger. At this point, the water molecules in the air condense into water droplets, expelling the treated dry air outside the machine. In this way, the indoor humidity is maintained at an appropriate relative humidity. The consumer group of industrial dehumidifiers: The product demand is not complicated, as long as it can meet the dehumidification needs, but they are highly sensitive to the price. It is powerful units and some research institutes and other institutions that have very high requirements for the performance of machines, and price is a secondary consideration.

Therefore, it is particularly important to minimize the entry of moisture into high-voltage switch cabinets and prevent the insulation performance of the switch cabinets from being damaged. For the moisture-proof treatment of high-voltage distribution rooms, the most effective moisture-proof measure is to use dehumidifiers. At the same time, prevent moisture from entering the distribution room and causing major damage.

The Naranda industrial dehumidifier is equipped with an intelligent humidity control system. Users can automatically control the operation and shutdown of the dehumidifier according to their own production needs. Through automatic control, the most effective dehumidification function is accomplished, thereby reducing the overall operating cost of the machine.
