SU110541A1 - Electric fence with electrospeaker to power it - Google Patents

Description

Electrical fences, consisting of racks with insulators, bare galvanized wire, power supply, contacts for power supply of the fence and grounding and an electric pulser, including a voltage transformer, a spiral spring, a current interrupter and a shunt capacitor, are complex in design.

In the described fence device, these disadvantages are eliminated by the fact that the transformer core is simultaneously used as a chopper electromagnet and made of two H-shaped halves mounted with an air gap to increase the secondary voltage and shorten the contact closing and opening time.

To increase the sensitivity of the tambourine, its axis is mounted in a stopper on a steel ball, and above the axis there is an adjusting sleeve with an external thread, screwed into the body of the electric pulsator.

For convenience and speed, the installation of posts in the soil and securing

the wires on them, the struts have a double-sided pedal, and their zigzag-type roller insulators in their head have two parallel grooves of rectangular cross-section and a flange around the insulator's head.

FIG. 1 shows a general view of a pens with an area of 3 ea for a herd of 100-120 cows or 200-300 calves enclosed by an electrical fence; in fig. 2 - fence in two projections; in fig. 3-rack insulator; in fig. 4 is a wiring diagram of an electric pulser; in fig. 5 is a longitudinal section of the upper part of the electric pulsator.

The fence is made of bare galvanized iron wire / with a diameter of up to 2.5 mm, which is tensioned by three corner 2 and a row of intermediate 3 posts. In one of the intervals between the intermediate posts 3, a passage for cattle running is arranged. The passage is closed by a length of wire 4 placed between the contact ring 5 and 5 and a ring 6 of insulating material.

The fourth corner post of the wire, which is longer than the others, is made in the form of a rod 7 for the pulsator 8, at the same time yush, the role of a grounding conductor. An independent earthing switch 9 can also be installed, connected to the pulsator 8 by a wire 10.

The corner stand 2 (Fig. 2) is a wooden bar with a metal tip and a pedal 12. For convenience and speeding up the deepening of the stand into the soil in the upper part, the plank 13 is reinforced with holes for stretching, which are not shown in FIG. 1 and 2.

Intermediate posts 3 (Fig. 1) differ from corner posts 2 only in the absence of a strip for stretching. At the end of the stand, a zigzag-type roller insulator 14 is mounted with a screw.

The isolator (Fig. 3) has two parallel grooves 15 and 16 of rectangular cross section, a groove 17 around the head of the insulator for laying the wire /, and also a hole 18 for the screw.

The electropulsator (Fig. 4) contains a transformer, a chopper with a capacitor and a master.

The transformer core, which is simultaneously an electromagnet of the chopper, is made of two W-shaped halves 19 and 20, separated by an air gap, which accelerates the opening of the primary circuit and increases the voltage in the secondary circuit. The transformer has two windings - primary 21 and secondary 22.

The primary winding is terminated at one end through the barker 23 of the chopper and the spiral spring 24 of the parallel 25 is connected to the positive pole of the battery 26 with a voltage of 4.5-6 volts. The second end of the primary winding is connected via a switch 27 to the negative pole of the battery. In the circuit of the primary winding 21 in parallel is connected to the capacitor 28.

The ends of the secondary winding 22 are connected to two contacts 29 and 30, one of which is connected to the wire / hedge, and the second to the grounding conductor.

The axis of the 31 tandem 25 (Fig. 5) for greater sensitivity of the tandem is mounted on one ball 32 subtitle 33 of the tandem. From above, the axis is held by a sleeve 34, which is screwed with its external thread into the bracket 35 of the pulsator case.

When the contact closes the switch 27 primary circuit

21 closes; The low voltage current from the battery 26 passes through the winding 21, thereby magnetising the transformer core, attracting the chopper 23 of the chopper, which gives impetus to the contact 36 of the motherboard, producing a sharp break in the primary circuit, and the capacitor 28 reduces the arcing and burning of the chopper contacts. Then, under the action of the spring 24, the contact 36 returns to its original position and closes with the bark 23, etc., as a result of which the closures and openings of the primary circuit are repeated.

In the moments of a sharp rupture of the primary circuit, in the secondary winding

22, a high voltage current (in the order of 10,000 volts) but a small power (0.3 ma is received. This current through the contact 29 enters the wire of the hedge and returns the contact 30 ′ through the ground 22 to the winding 22.

Thus, a pulsating current of low strength but high voltage continuously passes through the hedge wire. It has a harmless but unpleasant effect on an animal that touches the wire. As is well known from the operation of electrical fences, in animals, after two or three touches of the fence wire, a conditioned reflex is produced and in the future they avoid contact with the wire, which results in pasture animals without a shepherd.

When the animals eat grass in a fenced enclosure, the hedge is transferred to a new location. It takes two people to carry and a time of 1-1.2 hours on three hectares of pasture.
