Abstract

The invention relates to the technical field of data acquisition and analysis of a series compensation device and discloses a non-contact information acquisition health discrimination system of a series compensation device. The system comprises a noise sensor for monitoring working sounds of a series compensation device, a curent sensor for monitoring the current of a secondary circuit, a displacement sensor for monitoring the displacement changes of a circuit breaker and an isolating switch operating rod, and a thermal imaging module for monitoring the spectrum of the series compensation device. A DC signal isolator converts all measured signals into 0-5V voltages and the voltages are accessed to a single-chip microcomputer for analysis to determine the health state of the series compensation device and display the state. Meanwhile, the invention further discloses a method for judging the health state of the series compensation device, namely, the sensor is used for monitoring relateddata parameter changes of the series compensation device in real time, and the related data parameter changes are analyzed and processed by the single-chip microcomputer. According to the invention,the series compensation device and the secondary circuit control element thereof can be monitored in real time from multiple angles by adopting multiple means, and whether the working state of the series compensation device is normal or not is analyzed and judged.
