Early warning and predicting system for electric reactor

The invention belongs to the technical field of power equipment early warning, and particularly relates to an early warning and prediction system for an electric reactor. Comprising a collector module for collecting magnetic field, tone and current information and an early warning judgment module for judging the phase difference between zero-sequence current and zero-sequence voltage. The collector module comprises a current collection module, a magnetic field collection module, a tone collection module, a wireless radio frequency receiving module, a data processing single-chip microcomputer, a database, an alarm and a display screen, the collector receives collected data information, the data processing single-chip microcomputer processes the collected data information of each module, and gives a data analysis result; displaying on a display screen; and the early warning judgment module performs adaptive compensation and analysis under different fault conditions by monitoring the phase difference between the
