Description

Electricity cabinet dehumidifier and dehumanization method thereof
Technical field
The present invention relates to a kind of transformer station electricity cabinet dehumidify field, particularly a kind of electric cabinet dehumidifier and dehumanization method thereof.
Background technology
Transformer station's electricity cabinet comprises: high pressure, low-voltage distribution cabinet refer to change and consumed the effects such as break-make, control or protection for electric power system generating, transmission of electricity, distribution, electric energy.
The dehydrating unit that present domestic electric cabinet uses generally all is the heating dehumidifying, and dewatering type also has except wet method, but also is not promoted.
The cardinal principle of heating and dehumidification is to improve the hygroscopic capacity that air themperature can increase air, improves the aridity of box equipment.What at this moment reduce is the interior relative humidity of case, but can not reduce the absolute moisture content of air, in the constant situation of absolute moisture content, if humid air is cooled (day and night temperature or heater withdraw from), the relative humidity in the cabinet will rise and reach capacity, and temperature continues to descend, this is will produce condensation to condense in equipment surface, destroy insulation, flashover, short circuit occur or hit and alter phenomenon, affect the safe operation of electrical network.
Draining is by liquefying plant except wet method, makes a cryosurface, then airborne steam liquefy water on cryosurface discharged outside the case by specific structure, thereby draining can't solve the condensation problem that has formed in the cabinet except wet method.
How solving the condensation problem in the electric cabinet, and prevent again condensation, is this area technical problem to be solved.
Summary of the invention
It is thorough that technical problem to be solved by this invention provides a kind of dehumidifying, the quick solution condensation problem, and prevent again condensation, ensure electric cabinet dehumidifier and the dehumanization method thereof of electric equipment safe operation.
For solving the problems of the technologies described above, the invention provides a kind of electric cabinet dehumidifier, comprising: housing, be located at condensation, heater, control module, Temperature Humidity Sensor and fan in the housing.
Described condensation, heater, Temperature Humidity Sensor, fan all link to each other with control module.
Described condensation links to each other with the fin of heater, and quitting work at heater, and condensation is convenient to quick cold sink when beginning to freeze, and enlarges cryosurface to utilize fin, is beneficial to rapid condensation.
The present invention also provides a kind of dehumanization method of above-mentioned electric cabinet dehumidifier, comprises the steps:
(1) first by heater with the atmosphere temperature rising in the electric cabinet to preset temperature, with the condensation in the electric cabinet that gasifies;
(2) stopped heating then, and open condensation steam liquefaction in the electric cabinet is discharged.
During implementation, be higher than when setting the dehumidifying threshold values when control module monitors in the cabinet ambient humidity by Temperature Humidity Sensor, control fan first and heater is started working, fan is diffused into rapidly the heat on the heater in the cabinet, in-cabinet temperature is risen, the condensation in the electric cabinet that gasifies; When reaching design temperature, the control module control heater quits work, control fan discontinuous operation or the rotation of slowing down, the gas that is beneficial in the electric cabinet accelerates to flow, increase the touch opportunity of steam and condensation, when improving condensation effect, prevent the distinguished and admirable condensation evaporation that makes fast, make condensation effect reach best; Airborne steam in the cabinet is liquefied in condensation, then discharge outside the cabinet from the apocenosis passage of condensation one side bottom; Ambient humidity is lower than when setting the dehumidifying threshold values in control module monitors cabinet, and condensation and fan just quit work.
Technique effect of the present invention: electric cabinet dehumidifier of the present invention is by the dehumidifying that cooperatively interacts of heating and condensation method, dehumidifying thoroughly, and can the quick solution condensation problem, and by automation control and prevention condensation again, have effectively ensured the safety problem that electric equipment produces because of condensation.
Description of drawings
For making clearer being understood of the present invention's energy, below in conjunction with the drawings and specific embodiments the present invention is described in further detail:
Fig. 1 is the structural representation of electric cabinet dehumidifier of the present invention.
Specific embodiment
Such as Fig. 1, the electric cabinet dehumidifier of present embodiment comprises: housing 1, be located at condensation 2, heater 3, control module 4, Temperature Humidity Sensor and fan 5 in the housing 1.
Described condensation 2, heater 3, Temperature Humidity Sensor, fan 5 all link to each other with control module 4.
Described condensation 2 links to each other with the fin of heater 3, and quitting work at heater, and condensation is convenient to quick cold sink when beginning to freeze, and enlarges cryosurface to utilize fin, is beneficial to rapid condensation.
The dehumanization method of above-mentioned electric cabinet dehumidifier comprises the steps:
(1) first by heater 3 with the atmosphere temperature rising in the electric cabinet to preset temperature, with the condensation in the electric cabinet that gasifies;
(2) stopped heating then, and open condensation 2 steam liquefaction in the electric cabinet is discharged.
During implementation, be higher than when setting the dehumidifying threshold values when control module 4 monitors in the cabinet ambient humidity by Temperature Humidity Sensor, control first fan 5 and heater 3 is started working, fan 5 is diffused into rapidly the heat on the heater 3 in the cabinet, in-cabinet temperature is risen, the condensation in the electric cabinet that gasifies; When reaching design temperature (for example: 50-60 ℃), control module 4 control heaters 3 quit work, control condensation 2 is started working, and control fan 5 discontinuous operations or the rotation of slowing down, the gas that is beneficial in the electric cabinet accelerates to flow, and increases the touch opportunity of steam and condensation 2, when improving condensation effect, prevent the distinguished and admirable condensation evaporation that makes fast, make condensation effect reach best; Airborne steam in the cabinet is liquefied in condensation 2, then discharge outside the cabinet from the apocenosis passage of condensation 2 one side bottoms; Be lower than when setting dehumidifying threshold values (design parameter can be determined according to actual needs) when control module 4 monitors in the cabinet ambient humidity, condensation 2 just quits work with fan 5.
When described fan 5 rotates in deceleration, the 40-60% of rotating speed when its rotating speed is heater 3 work.
Obviously, above-described embodiment only is for example of the present invention clearly is described, and is not to be restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all execution modes exhaustive.And these belong to apparent variation or the change that spirit of the present invention extended out and still are among protection scope of the present invention.
