The utility model discloses an anti-theft remote intelligent alarm device for a 10kV to 20kV transformer. The device comprises a signal acquisition circuit, a signal judgment circuit and a remote alarm circuit, wherein the signal acquisition circuit can acquire a theft signal from a peripheral wire at the upper end of a transformer body and is connected with the signal judgment circuit in an output mode; the signal judgment circuit is connected with the remote alarm circuit in an output mode; and the remote alarm circuit can send the signal to an intelligent control center of a distribution network or a mobile phone of an electrician. When the transformer is stolen, the signal acquisition circuit acquires the signal, the signal judgment circuit judges the condition that the transformed is really damaged and stolen, and the remote alarm circuit immediately sends the signal to an alarm transmission circuit for remote alarm, so when receiving the alarm condition, a watchkeeper immediately goes to the field at the first time for handling. In the anti-theft remote intelligent alarm device for the 10kV to 20kV transformer, the advanced electronic technology is adopted, and a safe intelligent management for the transformer is developed, so as to reduce the accident, improve the power supply volume and increase the enterprise benefit and the social benefit.
