Abstract
The invention relates to a condensation-preventing dehumidifier for an electric cabinet, which comprises: the casing is located condensation subassembly, heater, control module, temperature and humidity sensor and the fan in the casing. And the condensation assembly, the heater, the temperature and humidity sensor and the fan are all connected with the control module. The dehumidification method of the anti-condensation electric cabinet dehumidifier comprises the following steps: (1) firstly, heating the air in the electric cabinet to a preset temperature through a heater to gasify condensation in the electric cabinet; (2) when the control module controls the heater to stop working and starts the condensing assembly to refrigerate, the fan is controlled to work intermittently to discharge water vapor in the electric cabinet in a liquefied manner; when the control module monitors that the ambient humidity in the cabinet is lower than a set dehumidification threshold value, the condensation assembly and the fan stop working.
Description
The application is Application No.：201210390115.7 invention and created name is《Electric cabinet dehumidifier and its dehumidifying side
Method》, the applying date is：The divisional application of the application for a patent for invention on October 15th, 2012.
Technical field
The present invention relates to a kind of transformer station's electricity cabinet dehumidifying field, more particularly to a kind of dehumidifying of anti-condensation electric cabinet dehumidifier
Method.
Background technology
Transformer station's electricity cabinet includes：High pressure, low-voltage distribution cabinet, refer to be used for power system generating, transmission of electricity, distribution, electric energy turn
Change and play break-make, control or protection etc. in consuming.
The dehydrating unit that domestic electric cabinet uses at present is typically all heating dehumidifying, and dewatering type also has except wet method, but also
It is not promoted.
The cardinal principle of heating and dehumidification is to improve air themperature to increase the hygroscopic capacity of air, improves the dry of box equipment
Dry degree.At this moment what is reduced is the relative humidity in case, but can not reduce the absolute moisture content of air, constant in absolute moisture content
In the case of, if humid air is cooled（Day and night temperature or heater exit）, the relative humidity in cabinet will rise and reach full
With, temperature continues to decline, and this is will to produce condensation to condense in equipment surface, destroys insulation, occur flashover, short circuit or hit alter it is existing
As influenceing the safe operation of power network.
Draining is by liquefying plant except wet method, manufactures a cryosurface, the steam in air is become on cryosurface
Then aqueous water, is discharged outside case by specific structure, thus the condensation that draining can not solve to have been formed in cabinet except wet method is asked
Topic.
How to solve the condensation problem in electric cabinet, and prevent condensation again, be this area technical problem to be solved.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of dehumidifying thoroughly, quickly solve condensation problem, and prevent again
Secondary condensation, ensure the dehumanization method of the anti-condensation electric cabinet dehumidifier of electrical equipment safe operation.
In order to solve the above technical problems, the invention provides a kind of anti-condensation electric cabinet dehumidifier, including：Housing, it is located at
Condensation, heater, control module, Temperature Humidity Sensor and fan in housing.
The condensation, heater, Temperature Humidity Sensor, fan are connected with control module.
The condensation is connected with the fin of heater, and to be stopped in heater, and condensation starts to make
When cold, it is easy to quick cold sink, to expand cryosurface using fin, beneficial to rapid condensation.
The dehumanization method of above-mentioned anti-condensation electric cabinet dehumidifier, comprises the following steps：
（1）Heater is first passed through by the atmosphere temperature rising in electric cabinet to preset temperature, with the condensation in the electric cabinet that gasifies；
（2）Then stop heating, and open condensation by steam liquefaction discharge in electric cabinet.
When it is implemented, when control module monitors that ambient humidity is higher than setting dehumidification valve in cabinet by Temperature Humidity Sensor
During value, fan and heater is first controlled to start working, fan rapidly diffuses into the heat on heater in cabinet, makes in-cabinet temperature
Rise, the condensation to gasify in electric cabinet；When the set temperature is reached, control module control heater is stopped, between control fan
Knock off and make or be rotated in deceleration, so that the gas in electric cabinet accelerates flowing, increase the touch opportunity of steam and condensation, carrying
While high condensation effect, prevent it is distinguished and admirable quickly evaporate condensation, condensation effect is reached optimal；To the steam in air in cabinet
Liquefied in condensation, then outside the apocenosis passage discharge cabinet of the side bottom of condensation one；When control module monitors
When ambient humidity is less than setting dehumidifying threshold values in cabinet, condensation is just stopped with fan.
The technique effect of the present invention：The dehumanization method of anti-condensation electric cabinet dehumidifier of the present invention by heating and
Condensation method, which cooperates, to dehumidify, and dehumidifying is thorough, and can quickly solve condensation problem, and by Automated condtrol prevention again
Condensation, effectively ensure electrical equipment because of safety problem caused by condensation.
Brief description of the drawings
For enable the invention to it is clearer be understood, below in conjunction with the accompanying drawings with specific embodiment to the present invention make further it is detailed
Describe in detail bright：
Fig. 1 is the structural representation of anti-condensation electric cabinet dehumidifier of the present invention.
Specific embodiment
Such as Fig. 1, the anti-condensation electric cabinet dehumidifier of the present embodiment includes：Housing 1, condensation 2 in housing 1,
Heater 3, control module 4, Temperature Humidity Sensor and fan 5.
The condensation 2, heater 3, Temperature Humidity Sensor, fan 5 are connected with control module 4.
The condensation 2 is connected with the fin of heater 3, and to be stopped in heater, and condensation starts
During refrigeration, it is easy to quick cold sink, to expand cryosurface using fin, beneficial to rapid condensation.
The dehumanization method of above-mentioned anti-condensation electric cabinet dehumidifier, comprises the following steps：
（1）Heater 3 is first passed through by the atmosphere temperature rising in electric cabinet to preset temperature, with the condensation in the electric cabinet that gasifies；
（2）Then stop heating, and open condensation 2 by steam liquefaction discharge in electric cabinet.
When it is implemented, when control module 4 monitors that ambient humidity dehumidifies higher than setting in cabinet by Temperature Humidity Sensor
During threshold values, first fan 5 and heater 3 is controlled to start working, fan 5 rapidly diffuses into the heat on heater 3 in cabinet, makes cabinet
Interior temperature rises, the condensation to gasify in electric cabinet；When reaching design temperature（Such as：50-60℃）When, the control heating of control module 4
Device 3 is stopped, and control condensation 2 is started working, and is controlled the discontinuous operation of fan 5 or be rotated in deceleration, in favor of in electric cabinet
Gas accelerate flowing, the touch opportunity of increase steam and condensation 2, while condensation effect is improved, prevent it is distinguished and admirable soon
Speed evaporates condensation, condensation effect is reached optimal；Steam in air in cabinet is liquefied in condensation 2, then
Outside the apocenosis passage discharge cabinet of the side bottom of condensation 2 one；When control module 4 monitors that ambient humidity removes less than setting in cabinet
Wet threshold values（Design parameter can determine according to being actually needed）When, condensation 2 is just stopped with fan 5.
For the fan 5 when being rotated in deceleration, its rotating speed is the 40-60% of rotating speed when heater 3 works.
