Description
Technical field
This utility model relates to the simulation of step voltage, in particular to a kind of reverse experience apparatus of step voltage.
Background technology
When electrical appliance enclosure or circuit one phase ground short circuit, around fault position, form different Potential distribution, when people walks close to fault position, between bipod, form step voltage. When step voltage reaches 40��50V, people will have Danger Electric shock risk, particularly strengthen the electric shock voltage of human body when step voltage easily makes people fall down, thus causing that people gets an electric shock and dies.
Traditional step voltage safety training is usually Course Training, plays safe teaching video or forward demonstration, and student cannot understand step voltage principle vividly, it is impossible to grasped the correct method fleeing from high-voltage earthing fault in-situ by hands-on mode. The device therefore, it is necessary to a kind of step voltage of research undergoes, shows step voltage formation basic theory intuitively, adopts on-the-spot hands-on mode to grasp the method fleeing from step voltage region.
Summary of the invention
This utility model aims to overcome that above-mentioned the deficiencies in the prior art provide a kind of reverse experience apparatus of step voltage, this device can simulate step voltage formation basic theory and scene, and student grasps the technical ability fleeing from high-voltage earthing fault in-situ by hands-on mode.
Realize this utility model purpose and the technical scheme is that a kind of reverse experience apparatus of step voltage, including:
Mimic bus, it includes simulation shaft tower, and described simulation shaft tower is provided with wire;
Simulation ground, described wire forms short circuit with simulation earth surface, forms multiple equipotential line centered by contact point, and each equipotential line is provided with multiple simulation footprint, described simulation footprint has proximity switch, and the proximity switch on every equipotential line is both connected on a relay;And
Control station, it includes PLC and controls module, warning lamp and phonetic alarm, and PLC controls module and is connected with warning lamp and phonetic alarm respectively, and described PLC controls module and is also connected with all relays.
In technique scheme, the reverse experience apparatus of described step voltage also includes DC source, and described DC source is connected with relay and control station respectively.
In technique scheme, described simulation shaft tower is additionally provided with insulator.
This utility model is by simulating power circuit ground short circuit fault, simulation ground is formed equipotential circle centered by wire pick-up point, student walks on footprint, the foot step of the student that undergoes training is sensed by proximity switch, when the proximity switch under two the simulation footprints being positioned on different equipotential line senses the step of the student that undergoes training, namely step voltage is produced, the relay conducting that now these two proximity switches connect, after PLC control module detects two relays conductings, then control warning lamp and phonetic alarm sends sound and light alarm, reflect that this student that undergoes training flees from the mistake of method, so that student grasps and correct flees from technical ability.
Accompanying drawing explanation
Fig. 1 is the structural representation of the reverse experience apparatus of this utility model step voltage.
Fig. 2 is the schematic top plan view of the reverse experience apparatus of this utility model step voltage.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As depicted in figs. 1 and 2, the reverse experience apparatus of step voltage includes mimic bus 100, simulation ground 200, DC source 500 and control station 600.
Mimic bus 100 includes simulation shaft tower 101, and simulation shaft tower 101 is provided with insulator 102 and wire 103, and mimic bus 100 carries out setting up according to actual track structure.
Wire 103 contacts formation short circuit with simulation ground 200, multiple equipotential line is formed centered by contact point, each equipotential line is embedded with multiple simulation footprint 300, each simulation footprint 300 has proximity switch, proximity switch is normally opened, proximity switch on every equipotential line is one group, is connected with a relay simultaneously.
Relay and control station 600 are connected with DC source 500 respectively, DC source 500 power, and used by the present embodiment, DC source 500 is DC24V. Control station 500 includes PLC control module 601, warning lamp 602 and phonetic alarm 603, PLC control module 601 and is connected with warning lamp 602 and phonetic alarm 603 respectively, and PLC controls module 601 and is also connected with all relays. When the proximity switch simulated under footprint 300 has sensed that foreign body passes through, can turn on by trigger relay, when PLC control module 601 has detected that two relays 402 turn on, namely represent and produce step voltage, then trigger alert lamp 602 and voice module 603 work, and produce sound and light alarm effect.
As shown in Figure 2, shown in simulation ground 200 be provided with simulation equipotential circular arc (201,202,203 etc.), maximum arc radius is set to 1.25m, for simulating the equipotential line that the electromotive force size formed with wired earth point is gradually reduced for the center of circle, different simulation equipotential circular arcs are provided with simulation footprint (301,302,303).
Use procedure of the present utility model is as follows:
In mimic bus 100, limit phase (the present embodiment is a wire 103) simulation broken string, is connected with simulation ground 200 either directly through wire 103. Analog band electric lead ground short circuit fault, moves closer to wire pick-up point (i.e. wire 103 and the contact point simulating ground 200), centered by wire pick-up point, define a Potential Distributing region, from pick-up point more away from, electric current is dispersion more, and ground potential is also more low.
In reverse experience of the process, student walks by simulation footprint 300 on simulation ground 200, when bipod steps down in the footprint on two equipotential lines respectively, two relay conductings can be triggered simultaneously, now, PLC controls module 601 and by logical judgment and exports signal, triggers voice module 602 and alarm lamp 602 works, produce sound and light alarm effect, represent that the track route of student and mode are wrong; When student's list lower limb or both legs close up and skip, then will not producing to report to the police, it is correct that method is fled from expression. By above-mentioned simulation process, it is possible to allow student is clear, be visually observed that step voltage formation basic theory, grasp high-voltage earthing fault in-situ method of fleeing from, and then improve prevention of electric shock consciousness and technical ability.
