Whether it is the southern region or the northern region, many power distribution room environment are generally exist in the humidity problem. Especially some built in the basement of the distribution room, a rainy day is more humid. A large amount of humid air through the underground cable layer or indoor cable trench, ventilation grille and other gaps indoors, the air humidity is gradually high, often up to 80% RH or more. The distribution room in the distribution cabinet is relatively poorly sealed, humid air is also very easy to enter the cabinet to produce condensation.
In electrical engineering, when the relative humidity is greater than 80% RH, known as high humidity environment. Long-term in a high humidity environment, on the one hand, will lead to reduced insulation properties of electrical equipment, moisture in the humid air adheres to the surface of the insulating material, so that the electrical equipment adiabatic resistance is reduced, the leakage current of the equipment is greatly increased, and it is very easy to produce the insulation breakdown and high-voltage discharge flickering phenomenon, resulting in safety accidents. On the other hand, the humid air is also easy to lead to the growth of bacteria, walls, ceilings, and many other places to appear a large area of mold and die, and the cabinet, switch contacts and other metal parts will be oxidized and rusted phenomenon, which are for the future use of the buried safety hazards.
For the often excessive humidity, air humidity distribution room, the most simple and effective solution is the overall dehumidification of the operating environment of the power equipment, not only dehumidification of the internal power equipment, but also dehumidification of the environment of the distribution room.
According to the actual situation of the distribution room, the characteristics of electrical equipment and operational requirements, the selection of the appropriate power dehumidifier. Usually, as long as the air humidity of the distribution room environment is strictly controlled below 60% RH, you can fundamentally solve the problem of humidity. In a relatively dry, humidity-suitable operating environment to ensure the normal operation and safety of equipment.
parkoo dehumidifier, with intelligent humidity constant control system, can automatically control the dehumidifier according to the need for work and shutdown, through automatic control to achieve the most effective dehumidification effect, reduce the operating costs of the machine. Precise temperature and humidity control also provides security for the power distribution room.
