Description
Technical field
The utility model is related to automation control area, specifically a kind of frequency-conversion control cabinet of visible at night.
Background technology
Frequency-conversion control cabinet is a kind of automation requisite equipment of electric control.Mechanically and electrically much automatically control on device equipment
System is all realized by switch board, is also regular switch board is operated through row in production and life process.But, due to
The restriction of environment, in the case that light is bad, impact uses.
Utility model content
Technical problem to be solved in the utility model there is provided a kind of frequency-conversion control cabinet of visible at night, structure letter
Single, reasonable in design, solve the problems, such as due to rather dark and affect using switch board.
The utility model now proposes technical scheme below：A kind of frequency-conversion control cabinet of visible at night, including housing, frequency conversion
Device, and axial flow blower, frequency converter is arranged in housing, and axial flow blower is arranged on housing, and described frequency-conversion control cabinet also includes shining
Bright device and controller, described lighting device includes LED, electromagnetic switch and luminance sensor, and described LED is arranged at housing
Top, and be connected on controller by electric wire, electromagnetic switch is arranged in controller, and luminance sensor is arranged on housing,
And by being electrically connected to controller.
Be additionally provided with temperature sensor in described frequency-conversion control cabinet, described temperature sensor by being electrically connected on controller,
Controller is passed to by the temperature signal that temperature sensor records, convenient control temperature, it is to avoid equipment high temperature failure.
Described axial flow blower, by being electrically connected to frequency converter, is easy to control the rotating speed of blower fan, to adjust switch board temperature.
Described frequency-conversion control cabinet is provided with overtemperature alarm, when switch board temperature exceedes setting value, will cause alarm
Report to the police.
Using above technical scheme of the present utility model, the beneficial effect that can reach has：By arranging on switch board
Lighting device, and arrange luminance sensor, automatically controls the open and close of LED, simple to operate, easy to use it is ensured that
The bright demand of operating environment, improves security.
Brief description
With reference to the accompanying drawings and detailed description the utility model is described in further detail.
Fig. 1 show a kind of schematic diagram of the frequency-conversion control cabinet of visible at night of the present utility model；
Fig. 2 show a kind of sectional view of the frequency-conversion control cabinet of visible at night of the present utility model.
Specific embodiment
See figures.1.and.2, a kind of frequency-conversion control cabinet of visible at night, including housing 1, frequency converter 2, and axial flow blower 3,
Frequency converter 2 is arranged in housing 1, and axial flow blower 3 is arranged on housing 1 and by being electrically connected to frequency converter 2, described VFC
Cabinet also includes lighting device and controller 4, and described lighting device includes LED 5, electromagnetic switch 6 and luminance sensor 7, described
LED 5 is arranged at housing 1 top, and is connected on controller 4 by electric wire, and electromagnetic switch 6 is arranged in controller 4, brightness
Sensor 7 is arranged on housing 1, and by being electrically connected to controller 4, is additionally provided with temperature sensor 8 in described frequency-conversion control cabinet,
By being electrically connected on controller 4, described frequency-conversion control cabinet is provided with overtemperature alarm 9 to described temperature sensor 8.Concrete control
Mode is：Luminance sensor 7 transmission luminance signal is to controller 4, when ambient brightness does not reach setting value requirement, controller 4
Electromagnetic switch 6 is controlled to open, circuit ON, LED 5 is bright, and otherwise LED 5 does not work；Temperature sensor 8 transmission temperature signal is given
Controller 4, when temperature exceedes setting value, controls frequency converter 2 to adjust the rotating speed of axial flow blower 3, when temperature oversteps the extreme limit setting
During value, overtemperature alarm 9 will be caused to report to the police, to play the effect of security warning.
Specific embodiment of the present utility model is not limited to above structure.The utility model also has other embodiment party
Formula, the improvement that every those skilled in the art are done under the spirit and principle of embodiment of the present utility model or change
Dynamic, all fall within protection domain of the present utility model.
