Abstract

The invention discloses an automatic electricity larceny leakage protection device. The automatic electricity larceny leakage protection device is characterized by comprising a current transformer, asignal amplifying circuit, a single-chip microcomputer circuit, a wireless communication module and a power supply circuit, wherein a resistor switch is connected to the two ends of a circuit at the detection part; a cooling fin is further arranged between a shell and the circuit board and is connected to a live wire and a null line in an output line of the power supply plug on the circuit board respectively. The upper portions of a static contact, where two side lifting arms of the static contact are riveted correspond to a movable contact on a movable contact bridge arm. By the adoption of the scheme, the device is low in cost, simple in structure, convenient to manufacture and capable of normally working under a low-temperature condition. In addition, wireless communication can be carried out, and the electric power bureau can remotely monitor the operation of the electric leakage protector.

Description
