Abstract

PURPOSE: To cut off power and prevent a high-voltage leakage current from flowing through a human body, by conducting the leakage current to a passage provided between the power side of a zero-phase-sequence current transformer and the casing of an electric apparatus.
CONSTITUTION: The passage 11 is provided between the casing 3a of a microwave oven 3 and the power side 2a' of the zero-phase-sequence current transformer so that the leakage current between the high and low voltage sides of a boosting transformer 4 flows through the passage 11. A discharge tube 11a and a resistor 11b are connected to each other in the passage. The firing voltage of the discharge tube 11a is set higher than the peak value of the primary voltage. The human body is protected from electric shock even if he touches the casing 3a of the microwave oven 3.
