Unit type dry air ring main unit

Technical Field

The utility model belongs to the technical field of power distribution cabinets, and particularly relates to a unit type dry air ring main unit.

Background

The dehumidification scheme of looped netowrk cabinet approximately divide into four kinds, installs electric heater additional in the cabinet, heats the equipment inside, through improving the interior temperature of cabinet, reduces the interior relative humidity of cabinet. A moisture-expelling agent is additionally arranged in the cabinet, and a silica gel bag or other water-absorbing materials is hung in the cabinet body to absorb moisture in the cabinet. A fan is arranged outside the cabinet, and the humidity in the electric cabinet is reduced by exchanging the air with external dry air through convection of the air. The gap between the incoming cable and the outgoing cable is plugged by using cement, and the cabinet door of the cabinet body is sealed by using a sealing rubber strip.

However, these solutions have more or less problems, and the electric heater is used to heat the interior of the device to solve the condensation phenomenon, but the heat source cannot be well controlled, and is basically arranged at the bottom or in a place where condensation is easy to occur, but the heat source is not well solved in other places after being dried at one place, and the local temperature is easily too high. A silica gel bag or other water absorption materials are hung in the cabinet body by using the moisture removing agent, however, actually, the effect is not obvious and the maintenance workload is increased because the water absorption effect is limited and the absorbed water is difficult to discharge. With the fan, exchange with external dry air through the convection current of air and reach humidity in the reduction regulator cubicle, the non-working when environment humidity is great easily causes dust, filthy entering can not realize dampproofing purpose. The cement plugging can only reduce the water vapor and cannot prevent the entry of moist air.

Therefore, design a looped netowrk cabinet, have and compare in above-mentioned several kinds of schemes better dehumidification effect.
