摘要：NOVELTY - The utility model claims a three-phase supply monitoring system ,relating to the technology area of the power supply monitoring wireless communication , comprising a voltage signal module, a voltage mutual inductor, the first AD736 mode, an electric current signal mode, an electric current mutual inductor, a LM741 module, the second AD736 module, a MCU module and a power supply exception processing module,etc. The utility model finishes carrying out detection of the voltage of the three-phase power supply, judging whether it is undervoltage or overvoltage;detecting the electric current of the three-phase power supply, judging whether it is undercurrent or over-current; carrying out detection of phase sequence of the three-phase power supply, judging whether it is underpahse or overphase;finishing reminding the working personnel to carry out power supply exception processing process; at the same time carrying out storage and remote monitoring to the detected state parameter of the three-phase power supply.
