Abstract
The utility model relates to a distribution box on-line voltage monitoring device, which comprises an electromagnetic induction circuit and a microprocessor control circuit. Signals acquired by the electromagnetic induction circuit are transmitted to the microprocessor control circuit through a trigger circuit. The output signals of the microprocessor control circuit are sent to a GSM module transmitting-receiving circuit and a communication alarm circuit. The device adopts induction electrodes to detect whether lines are electrified or not. After a microprocessor makes judgment, alarm information is emitted through a GSM module or an RS485 communication bus to a duty room. On-duty workers inside a control room are then informed in a timely manner. The device has the characteristics of simple circuits and no debugging requirements, etc.
