Intelligent fixed transformer iron core current data instrument

The utility model discloses an intelligent fixed transformer iron core current data instrument, which comprises a controller, a 4G module, a warning lamp, a display screen and a current transformer, the controller is electrically connected with the 4G module, the input end of the controller is electrically connected with the output end of the current transformer, and the output end of the controller is electrically connected with the input end of the warning lamp; the controller is electrically connected with the 4G module and the display screen. When the grounding current of the transformer is regularly inspected and measured, an inspector can directly read the reading in the display screen, so that the data is more intuitive and accurate, and the working efficiency of the inspection operation is greatly improved; when the iron core current value collected by the device is larger than the alarm value, the alarm lamp is turned on, and the 4G module of the device can send an alarm short message to a mobile pho
