High-voltage electric pulse feed system for electric protection circuit used in electric fence has connection to alternating current supply, rectifier and voltage doubling circuit

摘要

The electric fence energizing device (10) has terminals (220) connected to a 230 V alternating current supply. They are connected to a voltage doubling circuit (20) with capacitors (21,22) and diodes (23-26). The output of this circuit is connected via capacitors (30,35) and diodes (60,110) to the primary (75) of a pulse transformer (70). The main secondary (77) is connected to the electric fence. A measuring system has a small secondary (78) connected to a control circuit (120). The fence circuit incorporates a further transformer (190), a full wave rectifier (200), an alarm circuit (155) and an indicator circuit (150).
