Alternatives for gaz sf6 | 2020 | Siemens Energy Global

For example, the Zurich-based energy supplier EWZ has been using such a solution since 2015, and in 2019 a 380 kV plant was erected in Bavaria, Germany. However, these gas mixtures lose their effectiveness at very low temperatures. There is also a risk that equipment parts wear out more quickly, which in turn reduces switching capacity.Get price

Sulfur hexafluoride circuit breaker - Wikipedia

The first patents on the use of SF 6 as an interrupting medium were filed in Germany in 1938 by Vitaly Grosse and independently later in the United States in July 1951 by H. J. Lingal, T. E. Browne and A. P. Strom (Westinghouse). The first industrial application of SF 6 for current interruption dates to 1953. High-voltage 15 kV to 161 kV load switches were developed with a breaking capacity of 600 A.Get price
