Description
Technical field
The present invention relates to the technical fields of Electric Appliance Cabinet, more particularly, to a kind of three-phase imbalance regulating device.
Background technique
At present in AC network, since three-phase current difference generally requires to install three-phase imbalance adjusting additional in main power grid
Device, common three-phase imbalance adjuster using air blast cooling the type of cooling.But since three-phase imbalance adjusts utensil
Have the characteristics that following: 1, being typically mounted at open air；2, since circuit three-phase imbalance is dynamical state, so three-phase imbalance tune
The heat production for saving device is uneven, and heat output variance when peak valley is larger.
Due to the above characteristic, so the case where three-phase imbalance adjuster internal component is by cargo sweat frequent occurrence, especially
It is mounted near water source when three-phase imbalance adjuster, and when local climate rainy days is more.Three-phase voltage is big absolutely in power grid
Most cases are relatively stable, only three-phase imbalance state occur in peak times of power consumption.In that case, due to three-phase injustice
The adjuster internal component that weighs is standby for a long time, and surface temperature can be lower within certain a period of time, along with air blast cooling is set
It is standby by inside the continuous intrusion electric appliance of humid air, so in that case, liquefied water is easily adhered on internal element surface
Pearl, the damage of less serious case's member device is heavy then short circuit occurs, and destroys entire power grid.
Existing application publication number is that the patent of invention of CN108832644A discloses a kind of moisture-proof three-phase imbalance adjusting
Device.By upper fan and lower fan being arranged in cabinet come exhausting and blowing in the program, and it is arranged at ventilation opening by living
Property charcoal as drying layer made of water-absorbent material, humid air is guided by fan by drying layer, so that in humid air
Moisture absorbed by drying layer, achieve the effect that moisture-proof.
Above-mentioned prior art has the following deficiencies: that when external environment humidity is larger, heating air can not be big
The relative humidity of amplitude reduction air-flow, active carbon can absorb water always at this time no longer absorbs water after saturation, loses drying effect.
Summary of the invention
The object of the present invention is to provide a kind of three-phase imbalance regulating device, its advantage lies in being able to maintain good drying
Effect.
Foregoing invention purpose of the invention has the technical scheme that a kind of three-phase imbalance adjusts dress
It sets, including cabinet, is located in the box body desiccant body, the side of the cabinet is equipped with air inlet, and the air inlet is equipped with
