Abstract
PURPOSE: To improve reliability of an electricity detection unit by providing two voltage level detection circuits, where the output of the voltage divider of a high- tension line voltage is inputted commonly, and a digital operation circuit where outputs of these detection circuits are supplied.
CONSTITUTION: A high-tension line voltage is divided by voltage divider 1 and is given to voltage level detection circuits 2A and 2B as a common input. These circuits 2A and 2B output "1" for the input voltage over a prescribed value and output "0" for the input voltage of the prescribed value or less. Outputs of circuits 2A and 2B are given to digital operation circuit 6 to perform logical operation, and charging and non-charging are displayed on charging display output 7 by the OR output of them, and fault alarm is displayed on fault alarm display output 8 when one of circuits 2A and 2B is "1" and the other is "0". As a result, charging and non-charging of the high-tension line voltage can be detected except cases generated very rarely.
