Title:
ACTUATOR FOR ELECTRIC MEADOW FENCE
Document Type and Number:
Japanese Patent JPH01298699
Kind Code:
A
Abstract:
PURPOSE: To reduce radio wave failure as well as efficiently supply pulses to a meadow fence by internally detecting the load of an energizing device so as to control pulse output from plural signal generating means via a control means. CONSTITUTION: A parameter corresponding to a load via a load detection wire 7 connected to a pulse shaping circuit 6 for forming an energizing device together with pulse generators 2, 3 formed by a transformer, etc., is internally detected by a control circuit. In response to this detection, the thyristor switches of the generators 2, 3 are controlled by a control circuit and one side output pulse out of generators 2, 3 or both output pulses are supplied to the circuit 6 so that pulse electric power applied to electric meadow fences may be controlled in response to the load. Accordingly, pulses may be efficiently supplied to the meadow fences and also a radio wave failure may be reduced by supplying adequate pulses in comparison with supply of excessive pulse.
