Title: Innovations by Qiuxia Sun in Electrical Devices
Introduction
Qiuxia Sun is an inventor based in Tai'an, China. He has made significant contributions to the field of electrical devices, particularly in the area of gas detection in insulating oil. His innovative approach aims to enhance the efficiency and accuracy of monitoring electrical systems.
Latest Patent Applications
Qiuxia Sun's notable patent application is titled "SIMULTANEOUS DETECTION METHOD AND SYSTEM FOR DISSOLVED GAS AND PARTIAL DISCHARGE IN INSULATING OIL." This application describes a method that involves freely diffusing dissolved gas in insulating oil to an F-P optical fiber interference cavity through an oil-gas separation membrane. The process includes coupling pump light and probe light into the interference cavity via a frequency division multiplexer. The optoacoustic effect of the dissolved gas, stimulated by the pump light, causes the oil-gas separation membrane to vibrate. The probe light detects this vibration, which alters the cavity length, generating an interference signal.
Conclusion
Qiuxia Sun's work exemplifies the innovative spirit in the field of electrical devices, focusing on improving detection methods for better system reliability. His contributions are poised to make a significant impact in the industry.
