Summary of the invention
For solving the deficiency of prior art; The purpose of the utility model is to provide a kind of high-voltage charge display device; Electriferous state that not only can the effective monitoring high-tension unit can also in time carry out self check to display, guarantees the normal and reliability of its function; Can also guarantee effectively simultaneously that the abnormal conditions of mistake branch/splice grafting ground switch can not take place electrification in high voltage, guarantee the steady operation of display; In addition, this high-voltage charge display device also has advantages such as easy to use, compact conformation, life-span be long.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
A kind of high-voltage charge display device; Comprise box body with opening; Be used to the display panel that seals said opening and be fixedly connected with said box body; It is characterized in that said display panel is provided with and is used to indicate the pilot lamp group of each phase high tension loop electriferous state and is used to realize the feeler switch that the oneself detects, said box body inside also is provided with the control main board that is electrically connected with said pilot lamp group and feeler switch.
Aforesaid a kind of high-voltage charge display device is characterized in that said control main board comprises block sytem, and said display panel is provided with unblank pilot lamp and the locking pilot lamp that is electrically connected with said block sytem.
Aforesaid a kind of high-voltage charge display device is characterized in that, said pilot lamp group comprises three independent pilot lamp that are provided with.
Aforesaid a kind of high-voltage charge display device is characterized in that, said pilot lamp is a light emitting diode.
Aforesaid a kind of high-voltage charge display device is characterized in that, an outside surface of said box body is provided with the elementary diagram and the secure ID of high-voltage charge display device.
The usefulness of the utility model is: on the basis of the electriferous state of effective monitoring high-tension unit; Through increasing self-checking function display is realized that in time the oneself detects; Guarantee the normal and reliability of its function; Also increased block sytem simultaneously and unblanked accordingly/the locking pilot lamp, thereby guaranteed that the abnormal conditions of mistake branchs/splice grafting ground switch, the steady operation of assurance display can not take place electrification in high voltage; In addition, this high-voltage charge display device also has easy to use, compact conformation, long advantage of life-span.
Description of drawings
Fig. 1 is the structural representation of preferred embodiment of a kind of high-voltage charge display device of the utility model;
Fig. 2 is the structural representation of another kind of preferred embodiment of a kind of high-voltage charge display device of the utility model;
Fig. 3 is the principle schematic of preferred embodiment of a kind of high-voltage charge display device of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done concrete introduction.
Referring to Fig. 1, a kind of high-voltage charge display device of the utility model comprises box body and display panel, and box body has an opening, and display panel is just in time sealed this opening part and is fixed together with box body, constitutes the contour structures of this display jointly.In order to realize its demonstration and operating function, box body inside also is provided with control main board.
Monitor the electriferous state of high tension loop for the convenience of the users visually in real time, on display panel, be provided with the pilot lamp group, be used to indicate each phase high tension loop electriferous state.Preferred pilot lamp group is 3 pilot lamp L1, L2 and L3; Promptly when certain loop is charged, then pilot lamp that should the loop is shown as bright, certainly; The show state of pilot lamp is by the decision of the program of control main board; Pilot lamp is shown as and goes out when also can be in the loop charged, and this is the conversion that is easy to expect, does not give unnecessary details here.Referring to Fig. 1,3 pilot lamp can be independent the settings, also can be referring to Fig. 2; 3 pilot lamp are arranged on same place; On display panel, be divided into 3 zones, the latter's set-up mode is more succinct, and the installation region that a pilot lamp group only need be set on display panel gets final product.
Artificial or non-artificial fault in use might appear in high-voltage charge display device, causes showing losing efficacy even mistake, Given this; We are provided with feeler switch on this high-voltage charge display device, i.e. TEST key among Fig. 1 is under the state of no high-tension electricity; Connect working power; Press feeler switch, thereby realize that the oneself detects, and guarantees in time to get rid of the display non-fault.
In order further to prevent electrification in high voltage mistake branch/splice grafting ground switch; Cause mistakenly entering charged chamber, on control main board, be provided with block sytem, correspondingly; On display panel, also be provided with unblank pilot lamp and locking pilot lamp, thereby indication display unblanks/blocking effectively.
We know; Pilot lamp group, feeler switch and unblank/the locking pilot lamp all is the terminal of observing for the convenience of the users and operating; They must be electrically connected with control main board; Referring to Fig. 3, receive the signal of control main board feedback or order is fed back to control main board, could real various functions and the operation that realizes high-voltage charge display device.
