The invention relates to a transformer area low-voltage switch tripping monitoring system and method. The system comprises an acquisition unit, a monitoring unit, a communication unit and an interaction assembly, the acquisition unit is used for acquiring current, voltage and temperature signals of a transformer area power supply line; the monitoring unit is used for carrying out monitoring according to the current, voltage and temperature signals to obtain a monitoring result; the communication unit is used for transmitting an analysis result to the interaction assembly; and the interaction assembly is used for analyzing the result to obtain an analysis result and displaying the analysis result. According to the invention, the voltage, the current and the temperature of the transformer area power supply line are acquired by arranging sensors which can be rapidly installed, are sent to a metering chip for calculation, and are then sent to an intelligent gateway through a LoRa module, and sent to a cloud server through the intelligent gateway for analysis; and thus, the low-voltage power supply line of the transformer area is detected comprehensively, the low-voltage switch has lesstripping risks, and remote real-time monitoring is achieved.
