Background technology
At present the employed high voltage display device in home and abroad mostly use can not active illuminating liquid crystal display cells make the equipotential high voltage display device, so use cost is higher.In addition in use because display element can not active illuminating display effect heterodyne.
And application number is 200420003308.3, the applying date is on February 3rd, 2004, Granted publication day is on January 26th, 2005, the Chinese utility model patent that name is called " equipotential flash type high voltage live display device " discloses a kind of equipotential high voltage display device, this utility model has solved existing same device because can not active illuminating, very poor in the local display effect that environment is darker, the problem that is difficult to see.But the capacitor charge and discharge partial design of this patent circuit is complicated, and the flashlamp of its use all is cascaded, and makes the reliability of this device reduce, and promotes the use difficult.
The utility model content
The utility model has overcome the deficiencies in the prior art, and a kind of mesohigh electric power primary equipment that is applicable to is provided, and it is more simple that circuit discharges and recharges part-structure, and cost reduces, and shows the mesohigh potential indicator that the fixed equipment structure is also fairly simple and reliability is higher.
For solving above-mentioned technical matters, the utility model by the following technical solutions:
A kind of mesohigh potential indicator, the fixed equipment that comprises indicator, the power connection equipment that is electrically connected with the tested device maintenance, the shell of indicator, the flash of light parts that are provided with on the shell, induction electrode and the circuit board that is arranged on enclosure, described internal circuit board includes bridge rectifier circuit, capacitor C 1, and bidirectional trigger diode, two input ends of bridge rectifier circuit connect power connection equipment and at least one induction pole plate respectively, two output terminals of bridge rectifier circuit are two ends, bidirectional trigger diode and the one or more flash of light unit Series of edge joint capacitor C 1 respectively.
Further technical scheme is: described flash of light parts are light emitting diode, and bidirectional trigger diode is connected with one or more light emitting diodes with after a capacitor C 2 is in parallel.And described circuit board also comprises overvoltage protecting device, as: Transient Suppression Diode or semiconductor discharge tube, it is connected in parallel between two input ends of bridge rectifier circuit.
Described circuit board also includes resistance R 2 and connects with some light emitting diodes.
The utility model can also be that two or two light emitting diode series connection are set, and can certainly be that at least two group light emitting diodes are set, and connects between the light emitting diode of each group, and the light emitting diode between group and the group is then taked to be connected in parallel.
The power connection equipment that the utility model uses can be square jig of spring or elastic arc jig.And described fixed equipment is a standing screw, and standing screw links together shell and the square jig of elasticity or elastic arc jig and live wire.
Circuit theory of the present utility model is as follows: when tested device has working voltage, because the capacity effect that high voltage electrostatic induction causes, the induction pole plate of this device also can have induced voltage. by the pressure reduction between induction pole plate and the tested device, give capacitor C 1 charging. the pressure reduction of capacitor C 1 raises in the charging process, when being elevated to certain value, reach the conduction threshold that triggers bidirectional trigger diode, the two-way trigger tube conducting, 1 pair of entire circuit of capacitor C is discharged, while capacitor C 2 is also obtained part energy from capacitor C 1 and is stored. when bidirectional trigger diode returns to high-impedance state, capacitor C 1 stops discharge, meanwhile capacitor C 2 will be discharged. by these two continuous charge and discharge process of electric capacity, reach the constantly effect of flicker of flash of light parts.
Compared with prior art, the beneficial effects of the utility model are: the utility model is because fixed equipment is simple in structure, but also be provided with power connection equipment, can be installed in easily on the indoor outer mesohigh charging equipment, when having voltage on the central high voltage alive equipment, the flash of light parts will send very dazzling radiance, people around reminding note charging equipment, if when not having voltage on the electric equipment of mesohigh speed, the flash of light parts just can not send radiance, can improve safety coefficient greatly.And the electric elements cost that the utility model uses is low, and number is few, and mode in parallel after light emitting diode is taked to connect has improved product reliability greatly, is easy to especially apply.
