In addition, the electrical fence through the secondary winding of the high-voltage transformer and the resistor is connected to the output of the voltage regulator. In addition, the zener diode anode is connected to a common bus. FIG. a block diagram of a pulse generator for electrical fences; Fig. 2 is a variant of the circuit diagram of the generator. The pulse generator contains a sequentially switched on source 1 of constant voltage, containing a primary source 2 of direct current, a voltage regulator 3 and a constant voltage converter 4, a capacitive drive 5, switching device b , a high-voltage transformer 7, a trigger pulse driver 8, consisting of a series-connected resistor 9 and a capacitor 10, a shuntron shunted capacitor 11, an emitter follower 12 and carry etrichny multivibrator 13 is connected to its output to a control input of the converter 4, the DC voltage. In the initial state from the primary source 2 of direct current through the stabilizer 3, the voltage through the resistor 9 and the secondary winding of the transformer 7 is supplied to the electrical fence line. The capacitor 10 is charged, the zener diode 11 is locked. There is no signal at the input of the emitter follower 12, the supply from the voltage regulator 3 through the unbalanced multivibrator 13 to the constant voltage converter 4 is not supplied. Pulse generator does not produce. When an animal comes in contact with an electric hedge, a positive pulse is applied to the emitter follower 12 through the driver pulse shaper 8. The output of the latter is a pulse triggering an unbalanced multivibrator 13, which provides power from the voltage regulator 3 to constant voltage converter 4 and capacitive storage 5. Through the switching device, the capacitive storage device 5 is discharged to the primary winding of the high-voltage transformer 7. On the secondary winding appears high voltage pulse. One end of the high-voltage winding of the transformer is grounded through Zener diode 11, a high-voltage scaring impulse acting on the animal enters the line. In accordance with the selected time setting, the asymmetrical multivibrator 13 returns to its initial state and breaks the supply circuit between the stabilizer 3 and the constant voltage converter 4. The generator returns to its original state. Further, when a new inlet contact appears with a fence line, the operation of the pulse generator is repeated. When the insulation resistance of the fence line to the ground decreases due to weather conditions (rain, fog) or pollution and aging of the insulation, the pulse generator does not start, since this change is relatively slow. The use of the described pulse generator for electrical fencing will ensure, in comparison with existing pulse generators, selective operation when the leakage resistance of the fence line to the ground 4 decreases, as a result, the energy saving of the power source.
