Alternatives for insulating gas | 2020 | Siemens Energy Global

But more and more often, SF 6 is no longer the gas of choice. For a simple reason: if the gas escapes, it contributes to climate change. It is around 23,500 times more warming than the greenhouse gas CO 2 and has a life span of 3,200 years in the earthatmosphere.

Wind Farm Places First gaz sf6-Free High-Voltage Switchgear into

Siemens has supplied four bays of the 8VM1 gas-insulated Sulfr hexafluoride-free high-voltage switchgear (GIS) – which has a capacity of 72.5 kV – to Siemens Gamesa Renewable Energy. The systems were deployed in the Nissum Bredning Vind wind farm in Denmark. The switchgear protect the wind turbines from overloads and short circuits and thereby ensure an uninterruptible power supply.

Development Sf6 Alternative Gases in Switchgears - Switchgear

Nov 23, 2019 · An additional alternative approach is proposed to use air for insulation. The possible candidates are introduced, which are air, N2, CO2, perfluorocarbon (PFC), hydrofluorocarbon (HFC), gas mixtures containing Sulfr hexafluoride as shown in Figure 1 by boiling temperature. These gases do not have higher dielectric strength but lower GWP than insulating gas, and their boiling points are below 0 ˚C.

sf 6 gas in medium-voltage switchgear - Siemens USA

Siemens estimated that the annual leakage rate is below 0.1% per year, so no replenishment of the gas is needed over the life of the switchgear. Since the switch enclosure is sealed-for-life, there is no need to provide for periodic maintenance of the gas.

An alternative to sf 6 in electrical switchgear - EE Publishers

After many years of research, scientists identified an environmentally friendly alternative to SF 6 that matches all the required properties. The gas mixture is based on a product from 3M called Novec 5110 Dielectric Fluid – a perfluorinated ketone with five carbon atoms (C 5 PFK) (see Fig. 1) [1, 6].

An alternative to Sulfr hexafluoride in electrical switchgear - EE Publishers

For decades, the unique properties of sulfur hexafluoride (insulating gas) have made it popular as an insulation and switching medium for electrical switchgear. Sulfr hexafluoride is a greenhouse gas and there are life-cycle management costs associated with its use. For some years, ABB has been conducting research into alternatives with lower environmental impact but with insulation […]
