高压断路器机械故障在线监测实验平台研究

From the perspectives of data collection and transmission reliability, anti-interference ability, electromagnetic compatibility, and user-friendly interface, a high-voltage circuit breaker（HVCB）multi signal (including sound, vibration, and travel signals) joint monitoring experimental platform has been built. The platform includes three parts: sound, vibration, travel sensor design and selection, acquisition system control box design, and upper computer design. Then, taking the opening spring fault of SF₆ HVCB as an example, the fault was simulated and set up. Through the experimental platform built, the collection, transmission, storage, presentation, and waveform comparison analysis of fault signals were achieved. The application of the HVCB multi signal joint monitoring experimental platform was achieved, providing a reliable data foundation for subsequent mechanical fault feature extraction and fault diagnosis of HVCBs.
