A electromagnetic contactor with magnets to shut off DC circuit was set in the chamber. The enclosed gases are hydrogen, helium and clean air. The influence of enclosed gases and pressures on various properties was investigated. The arc duration ta, the arc energy Ea, and the contact resistance Rc were measured under the source voltage E from DC100 to 500 V, and closed contact current Io was 10, 20, and 30 A. As a result, it can be made clear that the magnitude of ta has a relation of H 2 < He <Air. We compared arc extinguish characteristics in the case of "no magnet" between air and hydrogen. At 200 V in the air, the arc extinction became impossible. However, in hydrogen, it was found that arc can be extinguished even at 500 V, 30 A (Maximum condition in this experiments). |
