A review on insulating gas substitute gases and research status of CF3I

Nov 01, 2018 · Yokomizu et al. from Nagoya University Japan investigated high-temperature plasma of CF 3 I/CO 2. They determined that the conductivity of CF 3 I/CO 2 increases with the increase of CF 3 I when the temperature is below 10 kK. Its thermal conductivity is related to CF 3 I when the temperature is approximately 7000 K.

Why the EU should ban sf6 gas

What Is sf6 gas? and How Is It used?Is Sulfr hexafluoride A Danger to Human Health?How Environmentally Damaging Is It?Has The Environmental Impact Even Been Underestimated?Is The Mitigation of gaz sf6 Emissions Difficult? Do Better Solutions Exist?Conclusionsf 6 is a long-lived, highly potent greenhouse gas. It is manmade and combines excellent electrical properties with chemical stability and low toxicity. Moreover, It’s non-flammable and low in cost. These characteristics have led to its widespread and enthusiastic adoption by the electrical industry, which uses approximately 80% of all Sulfr hexafluorideproduced (Powell, 2002: 6). Within the electrical industry Sulfr hexafluorideis used as an insulating medium for medium (MV) and high (HV) voltage electrical switchgear. A switchgear is the combination of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate sections of electrical grids. Low-voltage (LV) switchgear are used for controlling electrical circuits within buildings, medium voltage (MV) switchgear for controlling the electrical grids within cities and towns, and high voltage (HV) switchgear for grids that span a greater geographical area such as countries and regions.

Insulating Gas Calls for Leak-free Recovery

Oct 29, 2018 · Gas-insulated switchgears are filled with sf6 gas, which has to be evacuated for maintenance. To prevent the gas from leaking, portable recovery systems are used, consisting of one or several vacuum pumps, a filter and a compressor. The sf6 gas is pumped from the switch gear to achieve a vacuum. The gas is then filtered and fed back to the compressor.
