Transformer safety monitoring device

The invention discloses a transformer safety monitoring device. Comprising a distance measuring module, a control module, an alarm module and a communication module. Wherein the distance measuring module is arranged at the bottom of the transformer; the control module is used for sending a ranging instruction to the ranging module; the distance measuring module is used for measuring the distance between the bottom of the transformer and an object around the transformer after receiving the distance measuring instruction, and sending the measured distance data to the control module; and the control module is used for controlling the alarm module to send an alarm when the distance data does not meet the safety distance requirement, and sending a notification to a transformer manager through the communication module, so that 24-hour uninterrupted monitoring of the hidden danger of insufficient safety distance is realized, and when the distance data does not meet the safety distance requirement, the alarm module s
