Transformer tank alarm device

The utility model relates to a transformer tank alarm device, alarm device installs on transformer tank, including liquid level buoy, gravity sensor, treater, audible-visual annunciator, camera and remote monitoring end, the liquid level buoy is connected with gravity sensor, and gravity sensor and audible-visual annunciator are connected with the treater respectively, camera and remote monitoring hold respectively with the treater both way junction. A transformer tank alarm device, when reduced when the oil level, gravity sensor was drawn to liquid level buoy whereabouts under the action of gravity, gravity sensor with signal transmission to the treater in, audible-visual annunciator reports to the police, the shooting function is opened to the camera simultaneously to transmit to the treater, transmit remote control terminal through the treater, the real-time guard, the transformer damage is avoided in the action of stealing of the molecule of fighting crime effectively, and protection citizen and national property are not suffered a loss.
