Specific embodiment
It elaborates below in conjunction with specific embodiment to the utility model creation.
Power distribution cabinet mainly includes multiple cabinet body structures such as switchgear, transformer case, due to its using when be substantially at closing
In the environment of, it is influenced by internal component work and by external sunlight irradiation etc., in-cabinet temperature can be risen rapidly, be this
Utility model is provided with detection module first, the basic principle is that passing through the temperature etc. of temperature sensor measurement power distribution cabinet interior nodes
Related data, and above-mentioned data are transmitted to data gateway by way of wireless telecommunications and carry out protocol conversion, to enable
Occasionally be transmitted to single-chip microcontroller by RS232-USB interface and carry out processing control, at the same using the LabVIEW that can be operated on PC with
And MATLAB software carries out processing and Visualization to data, to realize that carrying out alarm as needed using remote center mentions
Show and network publication etc. extended operations.
Based on the temperature data that aforementioned detection module obtains, the utility model is also provided with control module in power distribution cabinet
Temperature is controlled to adjust, and zone of reasonableness is kept it in, the basic principle is that, detection is received by the AD mouth of STM single-chip microcontroller
The detection data that module obtains judges whether start-up temperature control by the way that temperature data to be compared with normal temperature data
System.Its particular content includes: to communicate the data obtained in data gateway by RS232-USB；Pass through LabVIEW front panel tune
The detection data in USB interface is obtained with NI-VISA, and corresponding control instruction is determined based on detection data, is started subsequent
Control function.
For the function of realizing detection module, it is necessary to obtain the testing numbers such as accurate temperature in power distribution cabinet by temperature sensor
According to, power distribution cabinet must include switchgear, the big major part of transformer case two, this two parts is also the region for needing emphasis to detect,
For switchgear, digital temperature sensor is directlyed adopt, such as the most common DIS18B20 sensor.But for transformation
For device cabinet, the intracorporal temperature of cabinet cannot directly react the temperature of transformer itself, temperature controlled straight for transformer
Connecing purpose is also to prevent transformer device core from overheating and not controlling the temperature of cabinet vivo environment, therefore for accurately to change
Depressor carries out temperature detection, and the utility model obtains the temperature data in transformer case using heat radiation type temperature sensor,
For the reliability for guaranteeing data, it is also necessary to carry out temperature calibration to sensor according to corresponding transformer, establish temperature and voltage
Relation curve between signal, and so that STM single-chip microcontroller is calculated temperature number according to the voltage signal collected by programming
According to；
For realize temperature control modules various functions, need to design complete temperature control system, due to switchgear with
And transformer case is the main heating source in power distribution cabinet, therefore the utility model is also emphatically to the temperature in switchgear and transformer case
Control module improves.Wherein transformer in transformer case itself is provided with corresponding radiator structure, including cooling fin
It improves it or realizes that the basis of temperature control function is the convection current for realizing air using blower Deng, the utility model, pass through
Certain type power distribution cabinet under sunshine condition to transformer case carry out fan radiating result data Fig. 1 it is found that transformer cabinet body temperature
Degree is directly related with power of fan, and power of fan is bigger, and temperature is lower, and meets the use standard (dry type of transformer case enough
The operation standard of transformer is≤60 DEG C).
Due to compact overall structure in switchgear and it is general be not attached to the structures such as cooling fin, the average thickness of component in cabinet
And size is bigger than normal, and it is lower using blower cooling efficiency, it is unable to satisfy actual use demand, therefore the utility model mainly uses water
Cold mode carries out temperature control, carries out the result data of water-cooling in sunshine condition lower switch cabinet by certain type power distribution cabinet
Fig. 2 is it can be found that after pump power constantly increases to a certain numerical value, and in-cabinet temperature is just with power (i.e. the flow of water) without straight
It connects relationship, therefore to avoid temporary derangement or temperature rise is too fast causes switch cabinet temperature out of control, should also except water-cooling system
The interim emergency cooling device of setting, such as emergency air-conditioning fast cooling device, and temperature threshold is set, when a threshold is exceeded, open
Dynamic money speed cooling device；
Since most power distribution cabinets are exposed to outdoor environment, influenced also can not by environmental pollution and special geographical environment
Ignore, the normal use of power distribution cabinet is needed in view of the adverse effect of salt fog and corrosive contaminants in air, therefore this reality
With the sensor that the detection module in novel further includes for detecting salt fog data or pollutant data, and use air-conditioning temperature-reducing
The method of dehumidifying is purged this salt fog and pollutant, is based on above-mentioned basis, overall framework figure such as Fig. 3 of the utility model
It is shown.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model creation, rather than it is right
The utility model creates the limitation of protection scope, although having made in detail referring to preferred embodiment to the utility model creation
It is bright, those skilled in the art should understand that, the technical solution that can be created to the utility model is modified or is waited
With replacement, the spirit and scope of technical solution is created without departing from the utility model.
