Definitions

  • the present invention relates to a self-expanding switch or circuit breaker, for the field of high or medium voltages.
  • Such a self-expanding and rotating arc circuit breaker combines the pneumatic blowing of the arc by expansion gases with a magnetic blowing of the rotating arc on annular electrodes.
  • This breaking method can be used in medium or high voltage circuit breakers and has the advantage of requiring low operating energies.
  • a first drawback is of purely dimensional nature. If we consider this known circuit breaker as it is for example shown, for a pole, in Figure 1 of the aforementioned document EP-A-0298809, it can be seen that the breaking chamber, itself relatively small, is surrounded by a rather bulky insulating enclosure. It is indeed necessary, for this known embodiment, to provide a sufficient expansion volume both above and below the breaking chamber, and in addition to provide a fairly wide annular communication corridor between these two volumes d 'expansion, upper and lower. The dimensions of the insulating tubular part, generally made of porcelain, of the sealed enclosure containing each pole of the circuit breaker are consequently large, which, especially for high voltages, is particularly penalizing in terms of size and cost.
  • the diameters of the expansion chamber and of the cut-off chamber are practically the same, so that these two chambers practically together form a long, tight enclosure, of tubular shape comprising two bottoms which constitute the two ranges opposite of current supply.
  • This device comprises a horizontal metal base 1 which forms the first range or current supply terminal and which carries in leaktight manner a long insulating tube 2 made of porcelain or another suitable insulator which constitutes the insulating cylindrical envelope of the chamber. expansion 3 of this self-expanding circuit breaker pole.
  • the other end of the elongated cylindrical casing 2 is sealed, in a sealed manner, with a coaxial and cylindrical metal bell 4 whose upper part forms the casing of the breaking chamber 5 of this pole of the circuit breaker, and which is substantially the same diameter as the insulating tube 2.
  • the horizontal upper metallic bottom 6 of the cylindrical bell 4 in the form of a thick and flat disc, forms the second range or terminal of current supply, opposite to the other range 1.
  • the metal tube 9 also crosses, in a leaktight manner thanks to a seal 15, another insulating annular spacer 16 which constitutes the other bottom of the actual cutting chamber 5.
  • a repulsion spring 12 which tends to separate these two tubes 8, 9 longitudinally from one another.
  • repulsion spring 18 is placed between the flange 11 of the tube 8 and the underside of the insulating spacer 16, in order to push the sliding tube 8 downwards and consequently to maintain its lower annular edge 19 in mechanical and electrical contact against the upper annular edge of a third metal tube 20 which is carried by the control rod 21 of this pole of the circuit breaker, itself held by a metal tube 36 in which it slides.
  • the interrupting chamber 5 is in itself very conventional, and comprises an annular and coaxial induction coil 22 which is fixed, by a tubular metallic transition 23, on the internal face of the metallic bottom 6 of the interrupting chamber 5, and which carries the fixed and annular arc electrode 24, combined with the movable arc electrode 13.
  • the metal tube 20 has a bulge 25 which forms the movable main contact of the circuit breaker and which is, in the closed position shown on the left half of the figure, connected to the fixed main contact 26 by an annular elastic clamp 27.
  • the tube 20 has radial openings 28 which put its internal space 29 into communication with the internal space 30 of the expansion chamber.
  • the operating rod 21 is then pulled down by conventional mechanical means and not shown.
  • the rods 20 and 8 then begin to descend, while the rod 9, held in place by the spring 12, remains stationary for the moment.
  • the movable main contact 25 then emerges, at point B in FIG. 2, from the clamp 27, conventionally causing the cutting, without creation of an arc since the arcing electrodes 13 and 24 are always in contact, the main contacts 25 , 26.
  • the rod 21 is then pulled as far as possible (point G) downwards, which ensures sufficient distance between the tubes 8 and 20.
  • the porcelain tube 2 here has a fairly small diameter, practically equal to that of the interrupting chamber 5: the assembly in fact forms a long and narrow tube, the lateral dimensions of which are small.
  • FIG. 3 An alternative embodiment is shown in Figure 3.
  • the tube 8, the spring 18 and the spacer 7 of Figure 1 no longer exist, and the tube 20 comprises, as for the device according to the document EP -A-0298809 cited above, a bearing face (not shown) of a spring 30 for repulsion towards the top of the tube 9, as well as a hook 31 for timed drive of this tube 9 towards the bottom, which allows conventionally to open the main contacts before the arcing contacts 24 and 13.
  • the insulating annular spacer 16 maintains in its center a small coaxial metal tube 32 whose lower edge 33 substantially exceeds the level of the lower face 35 of the insulating bottom 16, and whose upper edge 34 is at a distance of the fixed arc electrode 24 which is at least equal to the arc breaking distance (d).
  • This tube 32 has an inside diameter equal to the outside diameter of the movable conductive tube 9, so that the movable tube 9 can slide in this sheath tube 32. Means are provided to guarantee their positive electrical connection.
  • the tube 9 is shown at a distance (d) from arc cutting.
  • this tube 9 is continued to move back until, along the right half of this figure, the mechanical and electrical separation of the tubes 32 and 9. The voltage is then no longer applied to the tube 32, which is electrically isolated. By moving the tube 9 further back, a sufficient isolation distance is guaranteed as before.
