Abstract

Increasing the intensity of the interaction between switching arc and gas flow can lead to increasing the HV gas-blast devices thermal interruption ability. The numerical investigations of the two-pressure monoflow arc-extinguishing chamber equip with open heating volume are discussed. Numerical simulation and experimental data have shown that this chamber changes the gas parameters in the upstream region, so the thermal interruption ability increases.
