Circuit breakers play an extremely important role in power systems, and Sulfur Hexafluoride (hereinafter referred to as SF6) gas is the medium for main functions of circuit breakers, it has insulation arc suppression. After excavation SF6 reports on its application electric equipment recently related literature, inspiring author summarize - unique characters suppression operation principle, exp...

In order to realize the comprehensive analysis and evaluation of carbon emission reduction potential power supply enterprises, four measures were selected for evaluation, namely, building energy efficiency improvement clean utilization, sulfur hexafluoride control, reducing network loss rate, transportation utilization. view correlation various impact factors, analytic hierarchy process was ado...

Abstract An analytical method for detecting impurities in high-purity sulfur hexafluoride (SF 6 ) gas is established by using chromatography (GC) based on the enhanced plasma detector (EPD). The concentration of (hydrogen, oxygen, nitrogen, methane, carbon monoxide, dioxide, tetrafluoride, hexafluoroethane, and octafluoropropane) can be quantitatively detected through one-time sampling external...

A Mach 1.45 shock and subsequent reshock interacting with a high Atwood number interface between sulfur hexafluoride air is studied an adaptive mesh simulation more than 4.5 billion cells. Mechanisms governing the variable-density flow after shocks' interactions are analyzed transport equations. The figure shows mole fraction fields in numerical tube around just before (left) (right) reshock. R...

The external-cavity quantum cascade laser (ECQCL) is an ideal mid-infrared (MIR) spectral light source for determining large molecular-absorption features with broad transition bands. For this paper, a gas sensor system was developed using broadband tunable ECQCL and direct absorption spectroscopy detection scheme short path cell of 29.6 cm. signal detection, cheap miniaturized quartz crystal t...
