Abstract
The utility model relates to a dampproofing dehydrating unit suitable for in high -low pressure complete set cabinet, should dampproofing dehydrating unit by: temperature and humidity sensor, CPU microprocessor, signal processing unit, IO interface, power return circuit, semiconductor refrigeration piece, condenser and air circulation system constitute, wherein signal processing unit is including showing return circuit, clock circuit, RS485 communication interface, air circulation system includes radiator fan, thermal -insulated cotton, fin, CPU microprocessor is whole dehydrating unit's a core, temperature and humidity sensor, clock circuit, power return circuit, shows that return circuit, RS485 communication interface set up respectively around it, gives CPU microprocessor with the signal transfer who gathers, then CPU microprocessor passes through the IO interface with the result and carries for semiconductor refrigeration piece and air circulation system to dehydrating unit carries out corresponding action. When starting the dehumidification, the semiconductor refrigeration piece makes the condenser temperature reduce, utilizes air circulation system to force in the cabinet damp and hot air to form the air current and passes through the condenser, and damp and hot air current constantly produces the condensation at the condenser surface, and the condensation produces the phenomenon of dripping, get rid of the cabinet through drainage system outside to really reach the inside air humidity's of reduction equipment mesh.
Description
Technical field
This utility model belongs to field of electromechanical technology, particularly to a kind of suitable in the damp-proof moisture removing apparatus in high-low pressure complete cabinet.
Background technology
High-low pressure complete set of equipments plays an important role in the whole power transmission and distribution process of electrical network, in the area that humidity is bigger, for ensureing built-in electrical insulation level, it is ensured that device reliably working, it is desirable to taking measure moistureproof, anti-condensation in cabinet.
China adopts automatic heating and dehumidification controller to prevent condensation from having more than ten years history in switch cubicle, the mode of this heating and dehumidification is at moisture resistant, anti-condensation, ensure high-low pressure equipment reliability service serves positive role, but also occur in that some problems in the application, such as: when the air humidity of inside switch cabinet is higher, heater starting works, condensation is promoted to flash to damp-heat air, when damp-heat air runs into cold metal cabinet surface and electric equipment surface, the globule can be condensed into, especially complete set equipment, for meeting the degree of protection of outdoor equipment, general ventilation condition is poor, damp-heat air is difficult to and cabinet outer air forms convection current, damp-heat air still runs into metal at cabinet internal recycle, glass etc., it is easy for being formed condensation on surface.This with winter airtight automobile, to be easy to produce condensation on indoor glass be same reason.
Utility model content
For overcoming drawbacks described above, the purpose of this utility model is to provide a kind of suitable in the damp-proof moisture removing apparatus in high-low pressure complete cabinet.
A kind of suitable in the damp-proof moisture removing apparatus in high-low pressure complete cabinet, this device by: Temperature Humidity Sensor, CPU microprocessor, signal processing unit, I/O interface, electric power loop, semiconductor chilling plate, condenser and air circulation system form；Wherein said signal processing unit includes show circuit, clock circuit, RS485 communication interface；Described air circulation system includes radiator fan, heat insulation foam, fin；Described CPU microprocessor is the core of whole dehydrating unit, Temperature Humidity Sensor, clock circuit, electric power loop, show circuit, RS485 communication interface are separately positioned on about, send the signal collected to CPU microprocessor, then result is flowed to semiconductor chilling plate and air circulation system by CPU microprocessor by I/O interface, thus dehydrating unit carries out corresponding action.
Described damp-proof moisture removing apparatus operationally, by Temperature Humidity Sensor, gathers the air humidity within complete cabinet, transmits a signal to CPU microprocessor, judge whether environment meets dehumidifying condition by CPU microprocessor；If reaching dehumidifying condition, semiconductor chilling plate and air circulation system is then started by I/O interface, guide damp-heat air by dehydrating unit by air circulation system, the hydrone in damp-heat air is assembled on condenser and is condensed into water droplet, finally by drainage arrangement, water is discharged outside cabinet.
This utility model utilizes damp-heat air to meet the operation principle of cold meeting condensation, by semiconductor refrigerating technology and intelligent control technology, when starting dehumidifying, semiconductor chilling plate makes condenser temperature reduce, utilizing air circulation system to force damp-heat air in cabinet to form air-flow by condenser, damp and hot air-flow constantly produces condensation at condenser surface, and condensation produces dripping phenomenon, got rid of outside cabinet by drainage system, thus being really achieved the purpose reducing device interior air humidity.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of this utility model dehydrating unit；
Fig. 2 is this utility model dehydrating unit flow chart operationally.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in detail.
As shown in Figure 1 and Figure 2, a kind of suitable in the damp-proof moisture removing apparatus in high-low pressure complete cabinet, this device is made up of Temperature Humidity Sensor, CPU microprocessor, signal processing unit, I/O interface, electric power loop, semiconductor chilling plate, condenser and air circulation system.Wherein signal processing unit includes show circuit, clock circuit, RS485 communication interface；Air circulation system includes radiator fan, heat insulation foam, fin.CPU microprocessor is the core of whole dehydrating unit, Temperature Humidity Sensor, clock circuit, electric power loop, show circuit, RS485 communication interface are separately positioned on about, send the signal obtained to CPU microprocessor, then result is flowed to semiconductor chilling plate and air circulation system by CPU microprocessor by I/O interface, thus dehydrating unit carries out corresponding action.Because air circulation system can make the damp-heat air in high-low pressure complete cabinet form air-flow, and is discharged outside cabinet by condenser formation condensation.
This utility model is to pass through Temperature Humidity Sensor, gather the air humidity within complete cabinet, transmit a signal to CPU microprocessor, judge whether environment meets dehumidifying condition by CPU microprocessor, if reaching dehumidifying condition, semiconductor chilling plate and air circulation system is then started by I/O interface, damp-heat air is guided to pass through dehydrating unit by air circulation system, hydrone in damp-heat air is assembled on condenser and is condensed into water droplet, finally by drainage arrangement, water is discharged outside cabinet, thus reaching the purpose of dehumidifying, reduce air humidity in complete set of equipments.
With the beneficial effect of the technical program: the mode passively preventing condensation from dehumidifying, becoming positive guide condensation, reduce air humidity, effect on moisture extraction is obvious, effectively prevents component aging in complete set of equipments, and energy-conserving and environment-protective are low in energy consumption.
