Height, to accelerate the aging of electric appliance in cabinet；Simultaneously as the bottom of cabinet bulk of electric power cabinet is with cable duct due to being connected, cable duct
Interior humid air can enter in electric power cabinet, and there are the factors such as poorly sealed for the cabinet body of electric power cabinet in addition, to cause electric power cabinet
Interior of the cabinet humidity it is big, when temperature change is larger outdoors (such as day and night temperature), the interior of the cabinet condensation of electric power cabinet will be caused,
So as to cause occur in the cabinet of electric power cabinet electrical equipment dampness, burn into equipment fault the problems such as.
Since electric power cabinet quantity is big and distribution is wide, the daily management maintenance of electric power cabinet is often easy to be ignored, but such as
Modern universal status is that a large amount of electric power cabinet in-cabinet temperature is high, humidity is high, condensation is serious, equipment corrosion is severe, seriously affects electricity
The safe operation and power supply reliability of gas equipment.
For this purpose, thering is Utilities Electric Co. or electric power cabinet manufacturing enterprise to start targetedly to research and develop with cooling or wet down or anti-condensation
The electric power cabinet of dew；Status of today are as follows: current outdoor electric cabinet is without any cooling measure；It is moisture-proof anti-condensation to mostly use tradition greatly
Heating device come anti-condensation to being implemented in cabinet, which has the following problems:
One, interior of the cabinet air is heated with heater, the degree of unsaturation for only increasing water vapor in air (reduces phase
To humidity), there is no the steam in cabinet to be discharged, air humidity content does not change in cabinet, and larger change occurs when meeting ambient temperature
It still will appear condensation when change in cabinet.
Two, it after heated temperature increases in cabinet, is easier to instead by (chimney effect on the water evaporation in bottom of cabinet cable duct well
Answer), increase air humidity content in cabinet.
Three, its ontology is awfully hot when heater works, and especially when environment temperature is higher, can accelerate surrounding insulating part, cable
Aging, shorten the service life of equipment, influence operational safety.
Four, it can not be checked under presence, confirm heater whether normal operation, the intracorporal humidity of cabinet can not be understood and coagulated
Reveal situation etc..If above- mentioned information in cabinet need to be obtained, it is necessary to maked an inspection tour one by one, heavy workload and low efficiency, nonetheless also without
Method accomplishes to understand its working condition in real time.
Therefore, a kind of electric power cabinet device that can overcome the above problem is needed.
Summary of the invention

The air inlet of grating structure is located on tank wall bottom；Air filter screen is installed on the air inlet of the cooling fan；The cabinet
Cabinet outer sensor is inside installed, control cabinet is installed in the electric power cabinet, be provided in the control cabinet processor, relay,
Communication module and alarm module are equipped with cabinet inner sensor on the outer wall of the control cabinet, pass in the cabinet outer sensor and cabinet
Sensor is connected with processor, and the processor is connected with relay, communication module and alarm module respectively, the communication
Module is connected by communication with background server, and the relay, which is worn, to be connect in the power supply line of cooling fan；The cooling fan is
The control terminal of frequency conversion fan, the frequency conversion fan is connected to processor；The communication module is GPRS network communication module；The report
Alert module is acousto-optic-electric alarm module；Ambient temperature and in-cabinet temperature are obtained by cabinet outer sensor and cabinet inner sensor, when
When processor detects that ambient temperature and in-cabinet temperature difference are more than preset value, starting cooling fan imports cooling wind；Work as processor
When detecting that ambient temperature and in-cabinet temperature difference are more than early warning value, onsite alarming is carried out by alarm module, and pass through communication mould
Block sends warning message to background server.
Compared with prior art, the beneficial effects of the present invention are:
Aiming at the problem that current outdoor electric cabinet internal high temperature, high humidity and condensation, the use of device abandoning tradition adds the present invention
Hot device implements electric power cabinet and drives the anti-condensation method of tide, which can balance summer outdoor electric cabinet and be conducted by solar radiation to cabinet
Interior calorific value effectively controls interior of the cabinet humidity, and fundamentally solves electric power cabinet condensation problem, improves equipment operation
Safety；And inside outer air stream by air inlet in journey and exhaust outlet interval farther out, thus convenient to equipment in electric power cabinet cabinet
It radiates；
Meanwhile the present apparatus can realize telecommunication through communication modules such as GPRS, realization shows all real-time fortune on monitor supervision platform
Row data and warning message.Also a wechat monitor supervision platform can be established, operation maintenance personnel implementing monitoring is convenient for.Reach unmanned intelligence
