Definitions

  • This invention relates to electric netting for use as temporary and semi-permanent fencing for animal control.
  • the lowermost horizontal element is electrically insulated or is of electrically non-conductive materials.
  • the electrical connector at one end is connected to a live power source and a connector on the other end is plugged to a
  • the lowermost horizontal element is electrically conductive and, being in contact with the ground and with the metallic ground spikes of the supporting fence posts, is so connected as to have an earth or negative potential. It has been found that, with mesh-type fencing in which the vertical elements are composed of flexible twines, upwards variation in ground contour between adjacent supporting posts can bring the lowermost horizontal conductive element, which is of negative potential, into contact with the second lowermost horizontal conductive element, which is of positive or live potential. This can result in a short circuit with the consequence that the fence is rendered electrically ineffective.
  • the invention consists in electrifiable netting comprising a plurality of generally orthogonal elements interconnected to form a mesh such that when supported on posts there are two series of elements, one generally vertical and the other generally horizontal, wherein the lowermost horizontal element and the vertical elements are electrically non-conductive and wherein the remaining horizontal elements are electrically conductive and connected to one another and to respective electrical connectors at each ' end of the length of netting so as to form two interleaved but mutually insulated sets.
  • this new configuration enables the fence to be operated either with the two sets of electrically conductive horizontal elements connected respectively to the live terminal of a power supply and the earth or, alternatively, with both sets of elements connected to the live terminal of a power supply.
  • the elements of one set alternate with the elements of the other .set and all the horizontal elements other than lowermost fall within one set or the other.
  • the electrically conductive elements may be flexible and, may comprise a carrier of non-conductive material and, one or more bare wires.
  • the generally vertical non- conductive elements may also be flexible.
  • the invention includes means for electrically connecting the connectors at the respective ends of the netting.
  • the invention consists in an electrifiable netting comprising a plurality of electrically conductive generally parallel elements interconnected into two sets such that all the elements can be made live or one set can be made live and the other earthed.
  • the invention further includes an electric fence including netting as defined above.
  • the fence may include a power source and means for connecting the power source to the netting such that the elements in one set are live and the elements in the other set are earthed.
  • Figure 1 is a diagrammatic representation of an electric fence using the electric netting according to one aspect of the invention
  • Figure 2 is a diagrammatic representation of an electric fence using the electric netting according to another aspect of the invention.
  • an electrically conductive net indicated at 10 comprises a mesh of horizontal elements 11 and vertical elements 12 which are interconnected at their intersections by knots or plastic welds 13.
  • the vertical elements 12 are non-conductive as is the bottom horizontal element 14.
  • the other horizontal elements 11 are divided into sets 15 and 16; set 16 being shown in broader lines, for illustration purposes only.
  • the elements 11 of these sets are electrically conducting and their free ends 17 and 18 are connected to respective connectors 19 and 20.
  • the said free ends are so insulated that the sets can be electrically independent of one another.
  • the ends of the wire in a set can be connected to a single insulated cable which has the connector 19 or 20 on its other end.
  • the fence is supported and affixed to the ground by fencing posts 21 which are electrically insulating throughout that portion of their structure which remains above the lowermost horizontal member 14.
  • fencing posts 21 which are electrically insulating throughout that portion of their structure which remains above the lowermost horizontal member 14.
  • the posts may be of any suitable material either self insulating or with insulators affixed.
  • the connector 19 at one end of the length of fencing 10 is connected to the live terminal 22 of the electric power source 23 which is earthed through the metal earth rod 24 of the power unit and connector 20 is also connected to the earth rod 24.
  • the connectors are the other end of the length or fencing 10 are connected to corresponding connectors on a further length of fencing.
  • the connectors 19 and 20 at one end of the length of fencing 10 are both connected to one another by a further connector 25 which is connected to the live terminal 22 of the electric power source 23 which is earthed through the metal rod 24.
  • the connectors at the other end of the length of fencing 10 are connected, as in Figure 1, to corresponding connectors on a further length of fencing.

Abstract

Le grillage décrit (10) se compose d'un treillis d'éléments horizontaux (11) et d'éléments verticaux (12) qui sont interconnectés à leurs intersections par des n÷uds ou des soudures de plastique (13). Les éléments verticaux (12) et l'élément horizontal du bas (14) sont électriquement non conducteurs. Les autres éléments horizontaux (11) sont divisés en groupes (15 et 16) ayant chacun ses extrémités libres (17, 18) connectées à des connecteurs correspondants (19 et 20). Ces groupes peuvent être électriquement indépendants entre eux.
