Description of drawings
Fig. 1 is the structural representation of the preferred embodiment of the high-voltage charge display device that has a nuclear phase function of the present invention;
Fig. 2 is the principle schematic of the preferred embodiment of the high-voltage charge display device that has a nuclear phase function of the present invention.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done concrete introduction.
Referring to Fig. 1; The high-voltage charge display device that has the nuclear phase function of the present invention comprises body; Body has constituted the part of this high-voltage charge display device contour structures, on one of them face of this body, is provided with display panel, the viewable area that just supplies the user to observe and operate.In addition, in order to realize its demonstration and operating function, box body inside also is provided with control main board.
One of function of this display is the charged state that makes things convenient for each high tension loop of user's immediate observation, in order to realize this function, on display panel, is provided with the pilot lamp group, is 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.
For the ease of the viewing lamp group, the position corresponding to pilot lamp on display panel also is formed with the lamp group window, so that the light of pilot lamp can see through, thus the effective electriferous state of show circuit.Preferred lamp group window is that transparent resin material is processed.
In order to further expand the function of high-voltage charge display device; On the panel of this display, also be provided with nuclear phase jack as the phase test end; Can utilize phase comparator that dual power supply is carried out the phase bit comparison; The plug at the two ends of comparer is inserted respectively on a certain phase test end of two power supplys, observe the luminous situation of phase comparator pilot lamp.Generally, when phase place was identical, the pilot lamp of comparer was shown as and goes out, and phase place is not simultaneously, and the pilot lamp of comparer is shown as bright.Preferred nuclear phase jack quantity is 3, and A1, A2, A3 are arranged at the next door of pilot lamp L1, L2, L3 respectively.
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 testing button TEST on this high-voltage charge display device, referring to Fig. 1, under the state of no high-tension electricity; Connect working power; Press testing button TEST, thereby realize that the oneself detects, and guarantees in time to get rid of the display non-fault.
