Abstract
The present disclosure relates to the technical field of electrical device state monitoring, and particularly discloses an open-phase fault monitoring system, in which a relay communication unit is configured with an MCU as a central control processing unit, and an external ADC realizes high-speed A/D conversion for a plurality of signals; a timing function is realized by a GNSS&RTC of the relay communication unit, a data interaction function is realized by a LORA module, and data is sent to a background industrial personal computer based on a designed sampling frequency. The system of the present disclosure has the advantages of small volume, high precision, low cost, easy installation and the like, and realizes real-time monitoring and accurate identification of a line open-phase fault of an auxiliary power supply system in a nuclear power plant.
