Formula teaching method, effect are not obvious enough.Student does not have the importance of immersion electric leakage safety and the harmfulness of safety accident
Intuitive impression and understanding, are not achieved expected effect.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of immersion electric leakage body-sensing device, is used to educate
When training, student can be made to bring intuitive impression and understanding for the harmfulness of immersion electric leakage, play good result of training, and
Apparatus structure is simple and convenient practical.
Above-mentioned technical problem is solved, the utility model uses following technical scheme:
A kind of immersion electric leakage body-sensing device, it is characterized in that including:
Insulating base 3；
Target 2, is fixed on insulating base；

Plate 3 constitutes a water container and filled with conductive water；
At least one internal electrode 4 is that short tube is cyclic annular, is erected on insulating base 3 and is looped around target 2 and outside
Between electrode 1, water hole which is provided with, for allowing water free flow；
Pressure regulator inputs alternating current, and two output ends are coupled on target 2 and external electrode 1, and two output ends
It is parallel on voltmeter and an output end and is in series with ammeter, input terminal is equipped with earth leakage protective device.
The immersion electric leakage body-sensing device working principle of the utility model is as follows: by the intermediate electricity of immersion electric leakage body-sensing device
Pole, external electrode and pressure regulator connection composition circuit, pressure regulator are used to adjust the voltage of immersion electric leakage body-sensing device.
When starting to carry out immersion leak(age) test, earth leakage protective device is closed, conductive water is poured into immersion electric leakage body-sensing device,
Circuit communication.Pressure regulator is adjusted, so that the electric current by internal electrode changes, within removing by calculation survey calculation current value
The lateral area (water hole very little is ignored) of portion's electrode being flooded can obtain current density.Pass through different internal electrodes
Different current densities, the variation feelings for the current density for allowing student to understand under different voltages and different distance in extent of flooding
Condition, to experience harm of the current leakage to the person after water logging.When terminating water inlet electric leakage body-sensing, earth leakage protective device is opened, then
Immersion electric leakage body-sensing device does not have electric current to pass through, and student can be allowed to understand the importance of installation earth leakage protective device.
On the basis of the above, the utility model can also be further improved:
Concatenated one controller of external ammeter on the output voltage regulator, controller have display module, display
Module shows the current density and voltage of each internal electrode.
In the utility model, internal electrode can be circular electrode or square electrode.
Preferably, the internal electrode is the ring electrode of short round tube, and target is set to the center of circle position of internal electrode
It sets.
Further, the external electrode is the ring electrode of short round tube, the center of circle of the internal electrode and external electrical
The center of circle of pole, target are overlapped setting.
Preferably, there are two the internal electrodes.
In the present invention, the water hole size and shape on internal electrode is not construed as limiting, and can be round hole, rectangular
Hole, slot or other irregularly-shaped holes, as long as water flow can be allowed to flow through between electrode.Preferably, the water hole is rectangular
Shape hole.
An embodiment of the present invention, there are four the water holes on each internal electrode, is radially symmetrical arranged and will
Internal electrode is divided into identical four parts.
The utility model has the following beneficial effects:
The immersion electric leakage body-sensing apparatus structure of the utility model is simple, and convenient and practical, when carrying out body-sensing training, student does not have to
Body carry out directly contact experience, will not to the person generate harm, pass through current density calculate and display, it can to student into
Row immersion electric leakage harm, the training of installation earth leakage protective device importance, improve result of training.
