ELECTRIC FENCE AND METHOD FOR CONTROLLING THE SAME, AND POWER-SUPPLY UNIT FOR ELECTRIC FENCE, VOLTAGE GENERATOR FOR ELECTRIC FENCE, AND CONTROL CIRCUIT FOR ELECTRIC FENCE

摘要

PROBLEM TO BE SOLVED: To provide an electric fence allowing a person to go through the fence at a desired position without being electrified, a method for controlling the electric fence, a power-supply unit for the electric fence, a voltage generator for the electric fence, and a control circuit for the electric fence.;SOLUTION: When a power switch 55 is on and a first electric wire 2 is not grounded by a connector 23, voltage of a power supply 60 is applied to the voltage generator 56 via a B contact 54 of a relay and voltage is generated. The generated voltage is applied to a second electric wire 3 (bare electric wires (3A-3D)). If a person or wild animal touches the bare electric wires (3A-3D), the person or wild animal receives impact. A ground bar 23B of the connector 23 is inserted into the ground, and a hook 23A of the connector 23 is hooked on the first electric wire 2 to ground the first electric wire 2. As a result, a coil 53 of the relay is excited and the B contact 54 of the relay is opened, so that the voltage of the power supply 60 is not applied to the voltage generator 56 and generation of voltage is stopped.;COPYRIGHT: (C)2012,JPO&INPIT
