Outdoor transformer anti -theft device

The utility model discloses an outdoor transformer anti -theft device, including installing the protection panel in the transformer bottom. Be equipped with the signal -radiation module of singlechip, pressure sensor module and connection singlechip on the protection panel, signal -radiation module is used for realizing the singlechip communication central with remote monitoring. Pressure sensor module includes silicon fiml piece, and excitation power supply, and the silicon fiml piece spreads into the semiconductor resistance of 4 equivalences and connects into wheatstone bridge in specific orientation, and wheatstone bridge connects excitation power supply, and the silicon fiml piece sets up in four pins bottoms of transformer, and pressure sensor module is to the singlechip output and the monitoring voltage of being done all can and being directly proportional by the pressure measurement. Singlechip, displacement sensor, pressure sensor module and signal -radiation module mutually support, realize the thef
