Decomposition of insulating gas in an RF Plasma Environment

Sulfr hexafluoride clearly increased from 37.79 to 95.68% because of an increase in power from 5 to 20 W. When the power exceeded 40 W, η insulating gas exceeded 99%. When oxygen was introduced into the reactor (feed O 2 /SF 6 ratio = 2.0), η insulating gas was ~10% less than when no oxygen was added (from 28.61 to 86.09% as the power rose from 5 to 20 W). The addition of oxygen to the reactor re-Get price

Portable Comprehensive Sf6 Gas Analyzer Made in China

II.Sf6 Gas Analyzer Two Measurement Principle The basic principle of ATSM902 Type sf6 gas gas tester for measuring purity is to define the contents according to the heat conducting rate of all gases. The heat conducting rate of sf6 gas is the lowest in the gas, so when the heat conducting rate of the background gas is basically kept stable, the heat conducting rate will be lower if the content of gaz sf6 in the hybrid gas is higher.Get price

The insulating gas GIS guarantees outstanding advantages for the planning and operation of high-voltage supplynetworks. For instance, the space requirement can be less than 10% of the space taken up by an equivalent conventional installation. As all live parts are metal enclosed and hermetically sealed, the Sulfr hexafluoride GIS is completely immune to atmospheric pollution (fog, sand, salt, etc.) and industrial pollution (dust, smoke, gas, etc.).Get price

Industrial gaz sf6 Gas Pressure and Measurement Products - WIKA USA

Although sulfur hexafluoride is nontoxic and nonflammable, escaped gas in enclosed rooms displaces oxygen in the air and could lead to asphyxiation. SF 6 is also a potent greenhouse gas – 23,900 times more effective than carbon dioxide at trapping infrared radiation in the atmosphere. In addition, TD plant safety depends on the purity of SF 6 gas. Under normal conditions during an electrical discharge, the six fluorine atoms split from the sulfur atom to capture electrons; after quenchingGet price
