Abstract
951,512. Arc rupturing in switches. LICENTIA PATENT - VERVVALTiJNGS - G.m.b.H. Feb. 14, 1962 [Feb. 20, 1961], No. 5654/62. Heading H2B. In an arc-chute having spaced conducing plates arranged transversely to the arc, the plates have one or more holes shaped or arranged so that the area of the hole or holes decreases in the direction of travel of the arc towards the exhaust end of the chute. This is stated to facilitate the entry of the arc into the plates and its rooting on to the plates. The holes 3 may be equal in size and diminish in number towards the exhaust end of the chute, Fig. 3, or may diminish in size towards the exhaust end of the chute, Fig. 5. They may be circular as shown or triangular in shape, Fig. 6 (not shown), or a single triangular hole may be provided, Fig. 7 (not shown). In Fig. 8, the plates are bent into a U-shape to form limbs 4 having the holes 3 and shorter limbs 5. When the arc roots on to the limbs 5, the current flowing through the bases 6 of the U-shaped plates sets up a magnetic field which acts to prevent the arc being blown out of the arcchute.
