Definitions

  • the present invention resides basically in arc extinguishing chamber means adapted for use with an electric switch having contact means upon the opening of which an arc is formed, which arc extinguishing chamber means comprise a plurality of arc extinguishing bailles arranged transversely to the arc to be extinguished.
  • the arrangement is such that sets of two consecutive spaced-apart bailles are electrically connected together at but one end to form a bame pair with the two bailles of each pair being of different lengths and having opposite free ends directed towards the contact means such that the free ends of the two bailles of each baille pair are spaced diiferent distances from the place whereat the arc to be extinguished is formed.
  • the bailles which the arc reaches first are ICC spaced relatively far apart. Consequently, the entry of the arc into the baille system is facilitated.
  • the arc continues to move into the arc extinguishing chamber, it reaches the shorter bailles which extend less far into the arc extinguishing chamber.
  • parts of the arc are short-circuited by the shorter bailles, which are electrically connected with the longer bailles, so that the arc will assume, a total length equal to Vone-half of its previous length. The number of base points of the arc remains the same.
  • the arc extinguishing chamber means combines the advantages of an arc extinguishing chamber incorporating closely spaced-together bailles with the advantages of an arc extinguishing chamber incorporating bailles which are spaced relatively far apart, without possessing the drawbacks of either of the two heretofore known types of arc extinguishing chambers.
  • FIGURE l is a sectional view of one embodiment of an arc extinguishing chamber according to the present invention.
  • FIGURE 2 is atop plan view of the arrangement shown in FIGURE 1, as seen in the direction of the arrow A.
  • FIGURE 2a is a diagrammatic view similar to FIG- URE 1 and shows the behavior of an arc entering the baille arrangement.
  • FIGURE 3 is a sectional view of another embodiment of an arc extinguishing chamber according to the present invention.
  • FIGURE 4 is a schematic illustration of the baille arrangement according to yet another embodiment of the present invention.
  • the switch comprises a movable contact bridge I which cooperates with two stationary contacts 2 which are aligned one behind the other as seen in FIGURE l so that only one of the two stationary contacts is illustrated.
  • Each stationary contact is formed with an elongated portion 3 which serves as a contact surface along which will run the arc which is formed upon the opening of the contact means 1, 2.
  • the arc extinguishing means comprise a housing 4 made of insulating material, and a plurality of substantially parallel bailles.
  • Each two consecutive bailles 6 and 6a are electrically connected together at their ends facing away from the contact means 1, 2, by a suitable electrical connection, as, for example, a transverse web 5, so that each set of bailles 6, 6a, will form a baille pair of which one baille, namely, the baille 6a, is shorter than the other, namely, baille 6. Consequently, an arc formed upon the opening of the contact means 1, 2, will readily move into the baille system and the formation of base points will likewise be facilitated.
  • the magnetic blowout coil which causes this movement is of conventional structure and therefore not shown.
  • the web 5 can tightly close the gap between the baffles 6, 6a, of each baille pair.
  • the web may be formed with a cut-out or opening 7 therethrough, or be otherwise perforated.
  • FIGURE 3 differs Vfrom the above-described one in that the bailles 16, 16a,lof each baille pair are arranged in planes forming an angle with each other, with all baille pairs being so positioned that the bailles are arranged in a sector about the place whereat the arc to be extinguished is formed.
  • FIGURE 3 also shows the arc in two stages of its propagation. In stage 8, the arc has just reached the free ends of the longer bailles 16 and has formed base points thereon.
  • stage 9 the arc has already travelled through part of the narrow gaps 1i) formed between the long baille 16 of one baille pair and the short baille 16a of the adjacent pair, as wellV as through the narrow gap 10a formed between the elongated portion 3 and the long baille 16 of the nearest baille pair.
  • the relatively wide gap-like spaces 11 between the two electrically connected bailles 16, 16a, of each baille pair serve to deionize the hot gases caused by the short-circuited partial arcs.
  • the electro-dynamic counter blowing eilect acting in the direction of the arrow B, cooperates with the other structure to prevent the arc from flashing out of the arc extinguishing chamber.
  • FIGURE 4 shows an arrangement in which the baille system includes not only a plurality of baille pairs each 4 constituted by a long baille 26 and a short baille 26a connected together by a transverse web 25, but also individual bales 12 which are not connected to any other baille.
  • a circuit breaker comprising, in combination: an electric switch having contact means upon the opening of which an arc is formed; and means forming an arc extinguishing chamber and comprising a plurality of arc extinguishing bailles arranged transversely to the arc to be extinguished, sets of two consecutive spaced-apart bailles being electrically connected together at but one end to form a baille pair with the two bailles of each pair being of dverent lengths and having their opposite free ends directed toward the contact means such that the free ends of the two bafiles of each baille pair are spaced dverent distances from the place whereat the arc to be extinguished is formed in consequence of which there, where the arc enters the baille arrangement, said bailles are spaced further apart than there, to whence the arc moves upon .propagation into the baille arrangement.
