2results about How to "Avoid merging" patented technology

This invention relates to a surge arrester condition monitoring system, comprising a data acquisition module, a lightning strike assessment module, a prediction module, and a threshold adjustment module. The data acquisition module collects current and voltage waveforms from multiple lightning strikes within a single lightning event, as well as the time intervals between adjacent strikes. The lightning strike assessment module calculates the intensity ratio of single lightning strikes based on the surge arrester's baseline withstand parameters, quantifies the cumulative effect of consecutive lightning strikes using a time interval-based correction coefficient, and obtains a weighted fusion index of the comprehensive impact of lightning events on the surge arrester. The prediction module uses this index, combined with the natural aging rate, to update the surge arrester's estimated remaining lifespan. The threshold adjustment module adjusts the abnormal monitoring thresholds for operating parameters such as leakage current, resistive current, and temperature based on the updated remaining lifespan. This invention achieves quantitative assessment of the surge arrester's aging state, dynamic prediction of remaining lifespan, and intelligent adjustment of monitoring thresholds, effectively improving the foresight and accuracy of condition monitoring.
