Technical field
It is a kind of for the electrical verification to high-voltage circuit that the utility model belongs to, and output control signal is carried out forced blocking to associative operation mechanism high-voltage electriferous display locking device is provided.
Background technology
The principle of high voltage display device is by an electrode being set in AC field, obtaining induced signal with capacitive coupling, and in a kind of electrical verification mode of induced signal as basis for estimation.Whether charged a kind of mode that induced signal is processed is to adopt the Low ESR input, obtains the electric current of induced signal, by obtaining flowing through the leakage current I of small resistor, then carries out I/V and transforms, carry out judgement according to V.The shortcoming of conventional high-voltage electriferous display locking device: the circuit that obtains and process leakage current signal is comparatively complicated.
Summary of the invention
The purpose of this utility model is to overcome some shortcoming and defect of above-mentioned technical existence, and a kind of high-voltage electriferous display locking device is provided.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of high-voltage electriferous display locking device, comprise the device rack, it is characterized in that, signalization processing unit in the described rack, the electrical verification display unit, the equipment self-inspection unit, power supply unit and output contact unit, described rack arranges sensor unit outward, described sensor unit receives the high-tension line transducing signal, I/V conversion through signal, the signal processing unit processes switching signal transfers to the apparatus logic circuit and carries out the logic judgement, logic is judged minute two paths of signals output, one the tunnel exports control signal with relay circuit, and another road is with LED light output display signal, and described relay circuit connects electromagnetic lock or microcomputer locking.
Compared with prior art, the utlity model has following beneficial effect:
1, it is simple and reliable that modular design makes the circuit that obtains and process leakage current signal, reduces the device cumulative volume.

Description of drawings
Fig. 1 is circuit flow process structural representation of the present utility model.
Embodiment
Below in conjunction with specific embodiment the utility model is described further:
In conjunction with Fig. 1, a kind of high-voltage electriferous display locking device described in the utility model, be comprised of several cell mesh such as sensor unit, signal processing unit, electrical verification display unit, equipment self-inspection unit, power supply unit, output contact unit, all parts all are contained in the rack except sensor unit.The utility model arranges an electrode in AC field, because induced charge will appear in electrostatic induction, with this input signal as device.Generally speaking, electrode and transmit cable and leakage impedance can occur along with the variation of time and natural conditions, and the various undesired signals in space have considerable influence for the transmission of input signal.Device adopts new principle to detect electric signal and force ground connection with minimum input impedance, and the amplitude with ground current takes out as useful electric signal simultaneously, thereby other undesired signal obtains stable input signal through the signal processing unit shielding.In addition, the surge signal is easier to miss through ground connection, can not affect other electric appliance loads.Through processing useful electric signal with the variation of the electric field situation in the reflection high-tension line, red, green LED light reflection high-tension line by device electricity or electroless state arranged, danger signal represents height and is pressed with electricity, green represents high pressure without electricity, if device is not worked, LED is without demonstration.Driving simultaneously relay work finishes the automatic control in loop or the function of forced blocking associative operation mechanism.
Technical indicator of the present utility model is as follows:
1) measuring accuracy 4uA (minimum value 1uA);
2) working temperature-40 ℃ is to+85 ℃;
3) main EMC index IV level;
4) sea level elevation 4850m;
5) IP grade IP55;
6) form uses PC (polycarbonate) material;
7) rack uses " Shi Naide " degree of protection IP66 stainless steel plastic-blasting rack;
8) fault warning contact output;
9) dead electricity contact output;
10) the 48 hours aging tests of high low temperature of dispatching from the factory, the test in 72 hours of switching on.
It is 35 to 500kV that the utility model is applied to electric pressure, and frequency is gas-insulated switchgear and the high-tension line of 50Hz or 60Hz, can prevent from moving, the generation of the pernicious security incident such as maintainer's mistakenly entering charged chamber and maloperation.
