Influence of the gassing materials, such as PA6, PMMA, and POM on the dielectric properties of air are investigated. In this work, the fundamental electron collision cross section data were carefully selected and validated. Then the species compositions of the air–organic vapor mixtures were calculated based on the Gibbs free energy minimization. Finally, the Townsend ionization coefficient, the Townsend electron attachment coefficient and the critical reduced electric field strength were derived from the calculated electron energy distribution function by solving the Boltzmann transport equation. The calculation results indicated that H;O with large attachment cross sections has a great impact on the critical reduced electric field strength of the air–organic vapor mixtures. On the other hand, the vaporization of gassing materials can help to increase the dielectric properties of air circuit breakers to some degree. 展开更多

The interest in managing electricity demand surfaced in earnest during the 1970s as economic,political,social,technological,and resource supply factors combined to change the electricity sectors’operating environment and its outlook for the future.Ever since then,a successive series of concepts have evolved as an effective way of mitigating these risks including:demand-side management(DSM),demand response(DR),and transactive energy. 展开更多
