Description
Technical field
This utility model relates to electrical equipment, particularly relates to a kind of switch cubicle centralized-control type dehydrating unit.
Background technology
In high-tension switch cabinet, equipment room is away from little, easily causes insulation to decline the most electric under hot and humid weather
Flashover, causes the situation of AC and DC ground connection to happen occasionally, and the safe operation to equipment adversely affects.
It is thus desirable to take certain measure to improve the humidity resistance of above-mentioned cabinet (case) equipment, ensure that it is internally dry
Degree.
High-tension switch cabinet produce condensation reason generally include following some: 1, the impact of external environment condition, such as
Area humidity is high, weather variations in temperature is big, cable trench water collecting, and switch cubicle is at basement, and humidity is high, in cabinet
Temperature (the most subaerial temperature) is less than ambient temperature；2, atmosphere draught-free in cabinet, generally switchs
Cabinet is all disposed within indoor, and existing state network operation pattern all uses unattended mode, it is impossible to artificially enter switch gear room
Row ventilates, and becomes inside switch cabinet air seal not circulate, and once has moisture to enter in cabinet, it is impossible to discharge, easily
Form condensation；The temperature difference of element in cabinet, high-tension switch cabinet is in operation, and own temperature is too high (particularly to be opened
Close duty ratio bigger), if heater puts into, in-cabinet temperature can be made further to raise, when now, equipment is temporary
Time be in the power down mode of gap, in cabinet, equipment surface temperature reduces rapidly, and steam will be attached to element surface,
Produce condensation.
In the prior art, dehumidify in the following ways: 1, install condensation controller and heater additional；2、
Blower fan is installed bottom switch cubicle；3, inside switch cabinet installs quasiconductor condensation-preventing device.
Automatic heating and dehumidification controller is actually used to prevent the existing more than ten years history of condensation in switch cubicle, this
Plant heating and dehumidification controller and serve positive role at moisture-resisting profit, anti-condensation guarantee high pressure equipment reliability service,
But in the area application having, also occur in that some problems, such as: at southern plum rain season, sometimes switch
Air humidity within cabinet is higher, and even in switch cubicle, local has dew condensation phenomenon, owing to being arranged in cabinet
The condensation sensing station in portion does not arrive the degree of condensation, or, condensation sensor is for a long time by air
Dust and gas attack, make the sensitivity of sensor be affected, and condensation controller can not start in time and adds
Hot device.The effect causing condensation to control is malfunctioning, brings threat to the safety of switchgear.
Use in high-tension switch cabinet and install electric heater additional and dehumidify, electric heater only humidity to local around
Air can only play humid air decomposition, makes humid air carry out gas and water separation, after hydrone is heated
Rising, cool down in high-tension switch cabinet surrounding or high-voltage switch gear pile crown surrounding devices, produce condensation, moisture depends on
Old remain in inside high-tension switch cabinet, make the electric elements in high-tension switch cabinet be easier to make moist on the contrary, unfavorable
In the safe operation of equipment, more can not effectively reduce bin interior humidity.
To arranging internal heating, the degree of unsaturation of water vapor in air can only be increased, not in cabinet
Steam is discharged, and can not fundamentally remove condensation.Because when electric heater works, surface temperature reaches 180 DEG C,
Life-time service easily causes damage, it is desirable to changes and must have a power failure, but high-tension switch cabinet power failure is difficult to very much.
The flowing of air in switch cubicle installation blower fan can strengthen cabinet, but, owing in switch cubicle, three are little
The particularity of cell structure, blower fan is not notable to low stream effect to the air of each room, even if there being a gas flowing,
Because cabinet humidity does not changes, do not reduce cabinet humidity yet, and because blower fan is contained in cabinet, bad judgement
Its quality, if there being damage, it is desirable to changes and must have a power failure, but high-voltage board power failure is difficult to very much.
Additionally, at each little indoor location condensation-preventing device of switch cubicle, its principle is by device blower fan inspiration cell
Interior moisture, becomes water by the type of cooling and discharges, to drop the humidity of each cell in switch gear room.But, because of it
Complete machine power is less, and power of fan is little, it will affect its working effect, and its electrical connecting wires and discharge pipe line are relatively
Difficult layout.Additionally, it is in also device is contained in cabinet, its quality of bad judgement, if there being damage, it is desirable to change also
Extremely it is difficult to.
