Abstract
PURPOSE: To prevent electric shock, by providing a circuit between the casing of an electric apparatus and the low voltage side of a boosting transformer to drive a relay when a current leaks from the high voltage side of the transformer and by actuating a switch coupled between the low voltage side of the transformer and a power source, through said relay.
CONSTITUTION: One end of the high-voltage secondary winding of the boosting transformer 12 is connected to the casing 14 of the electric apparatus. The circuit 6∼10 for driving the relay when the current leaks from the high voltage side of the transformer 12 is provided between the casing and the low voltage side of the transformer. The switch 3 connected between the low voltage side of the boosting transformer 12 and the power source is actuated through the relay.
