SU120714A1 - Universal electric fence - Google Patents

Description

Constructions of electrical fences in England are known for keeping shorn sheep. Electric fences or electroshepherds for keeping in pens of non-sheared fine-fleeced sheep do not exist either in the USSR or abroad.

A distinctive feature of the proposed electric fence is that, as a result of the use of known electrical equipment, it uses a high voltage, in the secondary winding, which is adjustable in the range from 5 to 100 kilovolts, and produces a sparkle of up to 13 cm. limits from 1.2 to 12 volts, voltage in the primary winding and adjustable frequency of high voltage current pulses in the range from 200 to 20 pulses / min.

These adjustable parameters make the electrofence universal and allow keeping in pasture pens of up to 18 hectares of various animals, including fine-fleeced sheep with thick hair up to 13 cm long.

FIG. 1 is a schematic diagram of a universal electric hedge; pas figs. 2 - diagram of the rack with insulators; in fig. 3 - coil with bark.

The set of equipment for a universal electric fence includes the following main components: inductor, battery, fence, and a roll with bark.

The induction coil from the IV-100 high-voltage inductor consists of a primary winding / and a secondary winding 2, worn on a common non-closed iron core 5.

The coil is installed in a casing made of thick cardboard, pasted over with leatherette.

At one end of the core of the coil, a metal lug is installed with a protrusion. A bark4 of an automatic shadow-shaped interrupter is attached to the collar tab. The anchor consists of the same jY 120714

Slatted strap and leaf spring. The heat-resistant contact 5 is attached at the bottom at the end of the core, equipped with devices for adjusting the gap between it and the core. A change in the frequency of the current pulses is achieved by changing this gap.

The automatic mantle-shaped breaker consists of a metal disk 6, a coil spring and a bracket with adjusting wires. A second contact 8 is attached to the end surface of the disk. By coil tensioning, a coarse adjustment of the frequency of current pulses in the hedge is performed. The bracket is designed for mounting a tiller and for fastening one of the ends of the coil spring.

A capacitor 9 is inserted into the circuit, parallel to the contacts of the automatic mantically shaped interrupter. The foot of the inductor is made of an insulating material with good reflectivity in order to prevent the coil from being heated by the sun. The housing of the device has four sockets - two for supplying power to the device, and two for connecting to the fence.

If the fence is used with one row of wires, then a grounding device is used. It consists of a wire with clips or plugs at the ends and a ground rod that is buried 30-50 cm into the ground.

The inductor is mounted on a ground rod, which serves simultaneously as a lightning conductor.

Both alternating and direct current from the battery 10, giving a voltage of 6-12 volts, can be used as the power source of the inductor.

DC sources can come from all types of batteries or dry cells.

It is advisable to use alkaline batteries NKN-45, as the most convenient to work in field conditions. A battery capacity of at least 45 amperes / hour is desirable.

From each battery bank, self-tapping is made to obtain the required voltage in each particular case of electrical fence.

The wire fence 11 consists of wire, racks, insulators, tubes, bolts, clips and discharger 12. A set of equipment for a universal electric fence provides a fence for pasture stock with an average stock of up to 16-18 hectares.

The hedge is fixed in two rows of wires, and the negative charge is supplied to the upper row and the positive charge to the lower row.

To eliminate the penetration of the insulation between the turns of the induction coil in the hedge, a surge is placed. It is a piece of wire, one end of which is bent and illuminated to the upper row of hedge wires. The bottom end of the pattern does not reach the bottom row of wires by 9-12 cm.

If a voltage above 90-120 thousand volts rises in a hedge, a spark will occur between the end of the arrester and the bottom wire of the hedge.

This eliminates the likelihood of induction coil breaking. The electric fence of the two-wire system provides the impact of an electric shock on the animal's body even in dry weather, regardless of the insulation properties of the soil and the hooves of animals. Galvanized wire with a diameter of 1.0 to 3-5 mm is used for the fence.

Wooden pillars-racks 13 are subdivided into main and intermediate ones. They differ in length and diameter. Racks

on top they are bound with an iron rim 14, they have two earrings 15 with holes through which a long thin bolt 16 is passed to install the nzol tor 17. A spacer tube 18 is mounted on the bolt to insulate the area of the fenced pasture and reduce the weight of the fence. up to twenty trusses of auxiliary supports 1.0–1.1 m long and 5–6 cm in diameter made of durable wood. Corner and intermediate racks should be made of angle iron 50x50 mm. Loops for insulators are welded to them. Auxiliary supports can also be made of angle iron 35X35 mm.

Insulators it is desirable to use porcelain type AIK-2 or tubular.

The fixture for fastening the wires consists of a metal clamp 19 with a oblique cut-out tube 20 welded to it and a clamping screw 21.

To increase the labor productivity when installing an electrical fence, as well as to secure the wires and their storage, unwinding and unwinding of the wire, a coil 22 is used. The coil 22 can also be used for this purpose, used in field communication for a telephone cable or coil for winding measuring wire, included in the set of measuring apparatus square-nested sekly. Pre-production samples of electrical fences were made at the All-Union Scientific Research Institute of Sheep and Goat Breeding in the city of Stavropol, tested at the state farm “Nevinnomyssky Stavropol Krai and demonstrated at the VSHV.
