摘要
The operation state of the transformer directly affects the stability of the entire power system. H2 is an important fault characteristic gas of a transformer, and its concentration and content can effectively reflect the operation state of the transformer. In this letter, the Zr-doped h-BN (Zr-BN) monolayer gas sensor for dissolved gas analysis in oil is proposed to realize real-time, accurate, and intelligent monitoring of transformer fault characteristic gas H2. Based on the first-principles density functional theory, the optimal doping structure of the Zr-BN monolayer was obtained. Then, the adsorption energy, charge transfer, total density of states, and band structure of Zr-BN monolayer interacting with H2 were calculated and analyzed. The results showed that the adsorption of H2 by the Zr-BN monolayer was between physical adsorption and chemical adsorption, and it had excellent sensitivity at multiple temperatures. This study provides a theoretical basis for the preparation of Zr-BN monolayer gas sensors and provides new ideas and approaches for the development of other gas sensors.
