at present, the dehumidification method for the power cabinet comprises the following steps: fan-type dehumidification, dehumidifying with a moisture-repellent agent, heating-type dehumidification and plugging, wherein,
(1) The fan type dehumidification achieves the purpose of reducing the humidity in the electrical cabinet by exchanging air with external dry air through convection of the air, and the fan type dehumidification does not work when the environmental humidity is high, so that dust and dirt are easy to enter and the moisture prevention cannot be realized;
(2) The dehumidifying agent is added for dehumidifying, a silica gel belt or other water-absorbing materials can be hung in a cabinet in the past, however, the effect is not obvious because the water-absorbing effect is limited and the absorbed water is difficult to discharge;
(3) Heating type dehumidification is through improving the interior temperature of cabinet, only reduces the interior relative humidity of cabinet to the water content of air in the cabinet is not reduced, in case when the environmental change, the damp and hot air can be the condensation rapidly, and does not solve the interior condensation problem of regulator cubicle. The dehumidification effect is not obvious, and potential safety hazards exist;
(4) the plugging can only reduce the entry of moisture and air and cannot prevent the entry of moisture and air.
in summary, the above methods cannot effectively solve the condensation phenomenon.
