Introduction to the Parallel Arc Extinguishing Scheme of SF6-free Vacuum Load Break Switches in MVRing Main Unit
2024-12-12 When the high-voltage circuit is disconnected, the voltage will break down the air to produce high-temperature and high-conductivity free gases, which appear as instantaneous high-temperature sparks, which are arcs. The damage of arc is very high: the arc will generate high temperature, which will ablate the surface of the contact and burn out the […]
