Opening of 132kV Breaker with Very Low sf 6 Pressure - CR4

Opening a completely isolated Sulfr hexafluoride breaker with very little or no sf6 gas gas (as if it were in a testing lab) would pose no threat to the health of the breaker. There is no auto-trip feature. I think auto-trip at such low gas pressure may not be desirable because arcing might start across the open contacts of breaker due to very less insulationGet price

Myth About Sulfr hexafluoride Gas In Electrical Equipment

Apr 12, 2021 · From 0kV thru 800kV Sulfr hexafluoride is my choice for the insulating and arc-extinguishing characteristics delivered by sf6 gas. it is heavier than air, and just as the old OCB’s were designed, the sf 6 chamber and contacts are designed much like they were, whereby a “puff” of sf6 gas gas is jettisoned right through the arc zone thus assuring the thoroughGet price
