Abstract

gas is widely used in high-voltage electrical equipment and it is an important insulation and arc extinguishing medium. Its density and micro

water content are the main parameters describing these performance. Based on the analysis of density and micro water characterization methods and detection principles

this article proposes a fusion sensing method and technical implementation method for density and micro water content according to the reusable characteristics of density and micro water sensors. A SF

gas temperature

pressure

density and micro water online intelligent fusion sensing sensor with wireless transmission function has been developed

and its performance has been tested and verified in the laboratory. The successful development of this sensor not only makes the technology more economical and holistic

but also provides high-quality spatiotemporal data for SF

gas state monitoring

which is of great significance for improving the fault diagnosis and health management technology level of high-voltage electrical equipment.
