Transformer fault real-time detection alarm device and detection method thereof

The invention discloses a transformer fault real-time detection alarm device and a detection method thereof, and belongs to the technical field of electric power facilities, the transformer fault real-time detection alarm device comprises a shell, a fixed plate is fixedly mounted on the inner wall of the shell, a detection circuit board is fixedly mounted on the upper surface of the fixed plate, and an alarm lamp is fixedly mounted on the upper surface of the shell; a heat dissipation assembly is arranged on the inner wall of the top face of the protective net cover. According to the invention, by arranging the heat dissipation assembly, changing the angles of the fan blades, increasing the wind power generated by the fan blades, and automatically adjusting according to the temperature in the alarm device, the heat dissipation effect is improved, the situation of board burning of a circuit in the device caused by too high temperature is avoided, the working stability of the alarm device is further improved, a
