More Information
Summary:The utility model relates to structural design of an anti-theft alarm for power transformers and connected low-voltage transmission lines, wherein an improved circuit is composed of a sending circuit composed of a signal stolen generation circuit and an effective signal control circuit and a receiving circuit composed of an effective signal recognition circuit and a controlled alarm circuit; the sending circuit and the receiving circuit are respectively arranged on the alpha and the omega ends of the protected low-voltage transmission line; the effective signal is emitted by the signal generation circuit and is sent to the input end of the effective signal recognition circuit of the receiving circuit through the effective signal control circuit with the aid of the low-voltage transmission line; a triggering alarm signal is put out to the triggering end of the controlled alarm circuit through the effective signal recognition circuit. The device is provided with an independent battery power supply and adopts a wireless alarm device.
