1results about How to "Maintain security and stability" patented technology

The application provides a relay fault detection method and device, electronic equipment and storage medium, and belongs to the technical field of fault detection. The method comprises the following steps: acquiring electrical data, action time data, shell temperature data and environmental humidity data collected by a relay checker; the electrical data, the action time data, the shell temperature data and the environmental humidity data are respectively preprocessed to obtain a standard feature data set; the electrical data comprises power, current and voltage, and the action time data comprises attraction time and release time; abnormal mark data is determined based on the standard feature data set and rated reference data; correlation feature analysis is performed on the standard feature data set to obtain correlation abnormal mark data; fault risk data is obtained based on the abnormal mark data and the correlation abnormal mark data; and a fault determination result is obtained based on the fault risk data. The application can improve the accuracy of relay fault detection.
