摘要：
Displacement of an electrical arc between two parallel arc runners is studied with high-speed imaging, voltage, current and pressure measurements. The experimental set-up is detailed from the current source to the post-treatment methods. The influence of intensity, gas exhausts and volume behind the moving contact on arc commutation and movement are investigated. In the context of Low-Voltage Circuit Breaker (LVCB), it is shown that for high-intensity arcs, evacuating the hot gas is necessary for a good motion of the arc. Furthermore, a configuration of exhaust allowing a quick movement will not work for all current levels.
