GLOBAL EMISSION SOURCES OF GREENHOUSE GAS …

Greenhouse gas emissions from industrial processes are presently about 3% of global total CO2-eq. emissions ( Figure 1). However, this trend is increasing as illustrated in Figure 2, showing the trend in global total greenhouse gas emissions from 1980 to 1997.

Appliion and Recycling of SF6 gas Mixtures in Gas

Unlike pure SF 6 gas, handling and recycling SF 6 gas mixtures is a complex job, and it is in urgent need of an outline of handling and recycling SF 6 gas mixtures since more and more SF 6 gas mixtures insulated equipment are in service. In this paper, we introduce the situation of mixed-gas circuit breakers at different system voltage, and

A comparative study of arc behaviour in an auto-expansion

The equation of state and the thermodynamic and transport properties of SF 6-PTFE gas mixture are given in [].A semi-empirical radiation transport model of Zhang et al [] is used, which assumes a monotonic radial temperature profile with maximum temperature of T m on the axis. The radiation emission region is defined as that from the axis to the isotherm of 0.83T m (the arc core).

In addition, the field emission characters of the deposited films were measured in high vacuum system (6.0 × 10-4 Pa), and a highly stable field emission current density was obtained. The threshold voltages and the maximum electric current density of the sample were 82.1 V/ μm and 631.5 μA/cm-2 respectively.
