At the moment when the animal touches the electrical fencing 6, the duty voltage on the wires, equal to the supply voltage, decreases abruptly, as a voltage healer appears, formed by the limiting resistor 7 and the resistance of the animal's body . The voltage jump is per- formed on the input-differentiating circuit 9, and a mountain forms a pulse from the front of the surge voltage and amplifies it with a pulse amplifier 10. A one-shot 11 starts a strong signal, where it is formed impulsively with a contact time of about 100 -2OO ms. The one-shot 11 controls the key 14, opening it for the duration of the pulse. Key 14 triggers a multivibrator 15, which fills an impulse from sdnobibrator 11 series of high-frequency pulses, Seri enters the input of the converter 2, which converts low voltage to high voltage and creates a high voltage potential in the terminal 3, Block 12 differentiation forms impulse from the back of the one-shot pulse front l, which includes the start-up unit 13 of the switching element 4 at the time of the full arrays of the storage capacitor on the carrier 3, bpoc 13 turns on the switching element 4.
