Abstract
The utility model provides a constant-temperature power distribution cabinet belonging to the technical field of power distribution cabinets. The constant-temperature power distribution cabinet includes a cabinet body, an exhaust fan, a cabinet body inner shell, electric heaters, a temperature measuring set and a central processor. The exhaust fan, the electric heaters and the temperature measuring set are all connected to the central processor. The central processor is installed on the cabinet body inner shell. The cabinet body inner shell is installed in the cabinet body fixedly. The electric heaters are installed between the cabinet body inner shell and the cabinet body uniformly. The central processor can adjust temperature in the cabinet body, so that failures of electrical apparatus elements in the constant-temperature power distribution cabinet caused by too high or too low temperatures are avoided.
Description
Technical field
The utility model relates to the technical field of power distribution cabinet, particularly a kind of constant temperature power distribution cabinet.
Background technology
Power distribution cabinet be by the electrical wiring requirement be assembled in switchgear, measuring instrument, protection electrical equipment and auxiliary equipment in sealing or the semiclosed metal cabinet or the screen width of cloth on, constitute low-voltage distribution equipment.Can connect or the branch deenergizing by manual or automatic switch during normal the operation, cut off circuit or warning by protection electrical equipment when fault or irregular operating.Borrow measuring instrument can show operating various parameter, also can adjust some electric parameter, point out or send signal to departing from normal operating conditions.Low-voltage electrical apparatus in the power distribution cabinet is made up of fuse, A.C. contactor, RCD, capacitor and gauge table etc.These low-voltage electrical apparatuses all design and make by GB1497 " low-voltage electrical apparatus basic standard ", and their normal running conditions has been made respective specified: the upper limit of ambient air temperature is no more than 40 ℃; The mean value of ambient air temperature 24h is no more than 35 ℃; The lower limit of ambient air temperature is not less than-25 ℃.The power distribution cabinet of the upgrading of rural power grids is in outdoor operation, the direct irradiation that it not only is subjected to sunlight produces high temperature, simultaneously in servicely self also can produce heat, so high temperature season in full summer, temperature in the cabinet will reach more than 60 ℃, at this moment temperature has substantially exceeded these electrical equipment environment provided temperature, thereby can take place because of the overheated fault that causes of electric elements in the distribution cabinet.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of constant temperature power distribution cabinet, comprise: cabinet, it is characterized in that also comprising: ventilating fan, cabinet inner casing, electric heater, temperature measuring set, central processing unit, described ventilating fan, electric heater, temperature measuring set all link to each other with central processing unit, described central processing unit is installed on the described cabinet inner casing, and described cabinet inner casing is fixedly mounted in the described cabinet, and a plurality of described electric heaters evenly are installed between cabinet inner casing and the cabinet.
The beneficial effects of the utility model are: the outer temperature of temperature and cabinet is transferred to central processing unit in the cabinet that temperature measuring set is measured, central processing unit is according to the ceiling temperature of setting, in lower limit temperature and the distribution cabinet, the outer temperature difference of power distribution cabinet, the startup of control ventilating fan and electric heater with close, make the interior temperature constant of cabinet within the limits prescribed, make the electric elements temperature held stationary in the cabinet, more stable work, avoid because electric elements cause fault in the distribution cabinet that causes too high or too low for temperature, the cabinet inner casing is set have been reduced in the cabinet and the rate of heat exchange of ambient temperature, when heating, electric heater guarantees that the each several part temperature is even in the cabinet, the situation of local overheating can not occur.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model partial enlarged drawing.
Embodiment
Further specify according to above technical problem the utility model:
As Fig. 1, cabinet-1, ventilating fan-2, temperature measuring set-5, central processing unit-6;
As Fig. 2, cabinet inner casing-3, electric heater-4.
As Fig. 1, shown in Figure 2, temperature measuring set 5 is being monitored variations in temperature in the cabinet 1 and variation of ambient temperature in real time and data is being sent to central processing unit 6, central processing unit 6 control ventilating fans 2 start when reaching the upper limit numerical value that central processing unit 6 sets when the temperature in the cabinet inner casing 3 rises, identical with ambient temperature and during less than upper limit numerical value when the temperature in the cabinet inner casing 3, central processing unit 6 control ventilating fans 2 cut out, when ambient temperature ventilating fan 2 continuous firings during more than or equal to the temperature upper limit numerical value that sets, central processing unit 6 control electric heaters 4 start when reaching the lower limit numerical value that central processing unit 6 sets when temperature descends, when temperature in the cabinet inner casing 3 reached the mean value that sets temperature upper limit numerical value and lowest temperature numerical value, central processing unit 6 control electric heaters 4 cut out.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong to patent covering scope of the present utility model.
