Description
Technical field
Electrical equipment technical field is the utility model is related to, more particularly to a kind of anti-condensation switch cabinet.
Background technology
For switch cubicle as a kind of electrical equipment, interior part mainly has breaker, disconnecting switch, on-load switch, operation machine
Structure, transformer and various protection devices etc. form, main function be generated electricity in power system, transmitted electricity, distribution and electric energy
During conversion, folding, control and protection electrical equipment are carried out.Inside switch cabinet air circulation is poor, air humidity compared with
Height, condensation easily occurs in the case where internal-external temperature difference is larger, the safe operation to electrical equipment in cabinet causes serious threat.
Generally anti-condensation using switch cubicle heating at present, this method can not control the production of condensation in terms of air humidity
Raw, switch cubicle is long-term by the way of heating is anti-condensation under moist rainy environment, and the electrical equipment in switch cubicle can be used
Life-span and its safe and stable operation cause difficulty.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of anti-condensation switch cabinet, can be effectively out of cabinet
The outer temperature difference and the aspect of cabinet inner air humidity two control effectively to condensation of switch cabinet situation.
In order to solve the above technical problems, technical scheme is used by the utility model：A kind of anti-condensation switch cabinet, including
Cabinet, inside and outside in cabinet are respectively equipped with internal temperature sensor and external temperature sensor, are additionally provided with cabinet
Humidity sensor；Air outlet is provided with the bottom of cabinet side wall, air inlet is provided with the top of the side wall with air outlet opposite face,
Fan is provided with air outlet；The bottom of the cabinet is hollow structure, and heat coil is provided with the bottom of cabinet.
Preferably, in addition to controller, external temperature sensor, internal temperature sensor and humidity sensor and controller
Input electrical connection, fan and heat coil electrically connect with the output end of controller.
Preferably, air inlet is provided with the dust-proof air filter plate filled by silica-gel desiccant.
Preferably, the controller uses AT89S52 single-chip microcomputers, the internal temperature sensor and external temperature sensor
SM6610 temperature sensors are used, the humidity sensor uses LVQSZ-31 humidity sensors.
A kind of this new provided anti-condensation switch cabinet, by using said structure, has the advantages that：Can be right
The two condensation formation conditions of temperature and humidity are automatically controlled, both securely and reliably, it is convenient and swift, cumbersome people can be reduced again
Work operates.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples：
Fig. 1 is structural representation of the present utility model；
In figure：Cabinet 1, external temperature sensor 2.1, internal temperature sensor 2.2, humidity sensor 3, air inlet 4.1,

Embodiment
As shown in figure 1, a kind of anti-condensation switch cabinet, including cabinet 1, inside and outside in cabinet 1 are respectively equipped with inside
Temperature sensor 2.2 and external temperature sensor 2.1, are additionally provided with humidity sensor 3 in cabinet 1；In the bottom of the side wall of cabinet 1
Provided with air outlet 4.2, air inlet 4.1 is provided with the top of the side wall with the opposite face of air outlet 4.2, is provided with air outlet 4.2
Fan；The bottom of the cabinet 1 is hollow structure, and heat coil 5 is provided with the bottom of cabinet 1.
Preferably, in addition to controller 6, external temperature sensor 2.1, internal temperature sensor 2.2 and humidity sensor 3
Electrically connected with the input of controller 6, fan and heat coil 5 electrically connect with the output end of controller 6.
Preferably, the dust-proof air filter plate filled by silica-gel desiccant is provided with air inlet 4.1.
Preferably, the controller 6 uses AT89S52 single-chip microcomputers, and the controller 6 uses AT89S52 single-chip microcomputers, described
Internal temperature sensor 2.2 and external temperature sensor 2.1 use SM6610 temperature sensors, and the humidity sensor 3 is adopted
With LVQSZ-31 humidity sensors.
Cabinet internal-external temperature difference is monitored by the temperature sensor arranged inside and outside cabinet in real time, humidity sensor monitors in real time
Air humidity in cabinet, controller is according to institute's thermometric difference data and humidity data, selective control heat coil 5 or fan
Work, it also can control heat coil 5 and fan work to work simultaneously, with the temperature difference and air humidity in switch board body, prevent condensation
Generation.
External temperature sensor 2.1 and internal temperature sensor 2.2 are carried out in fact to the temperature of switch cabinet inside and outside respectively
When monitor, and Monitoring Data is passed into controller 6 and handled.If cabinet inside and outside temperature difference is more than 3 DEG C, controller 6 is controlled
Heat coil 5 processed carries out heating work, when cabinet internal-external temperature difference is less than 3 DEG C, stops heating.
The humidity sensor, the air humidity inside switch cabinet body can be monitored in real time, and number will be monitored
According to controller 6 is passed to, humidity threshold set in advance is compared controller 6 with the real-time humidity data received, if greatly
In preliminary setting data, then fan is controlled to be operated, when the humidity value monitored in real time, which is less than, presets humidity value, control
Fan is stopped.
The dust-proof air filter plate filled by silica-gel desiccant is provided with the air inlet 4.1, can be to access switch cabinet
Air in cabinet carries out moisture absorption, dedusting, and silica-gel desiccant absorption property height, and heat endurance is good, and chemical property is stable, and can
Reached by removing its moisture and recycle the purpose for reducing cost.Dust-proof air filter plate coordinates jointly with fan, reaches cabinet
