Definitions

  • the invention relates to the breaking chamber of an electric circuit breaker, comprising a arc forming chamber containing a fixed contact and a movable contact, which, at moment of their separation form an arc between them, said formation chamber communicating with the entrance to a second room, called arc extinction.
  • a circuit breaker comprising a breaking chamber, as previously described, is known from document DE 3,619,241.
  • the breaking chamber is delimited by side walls comprising reinforcing ribs made of material with the side walls and having a chamber cooling.
  • these walls increase heat dissipation at the level of the room dividers, but do not eliminate the risks of reclaking.
  • the present invention solves this problem and proposes a circuit breaker breaking chamber in which the risks of re-plating are considerably reduced.
  • the present invention relates to a breaking chamber of a circuit breaker electrical as described in claim 1.
  • the above-mentioned coolers are placed around the contact mobile.
  • the above-mentioned coolers are placed between the contact mobile and the aforementioned extinguishing chamber, at a predetermined distance from said contact mobile.
  • the aforementioned coolers are constituted by plates or tubes.
  • the above-mentioned coolers comprise two sets of ( plates parallel to each other, arranged on either side of the movable contact.
  • these plates extend substantially parallel to the movable contact.
  • the above-mentioned coolers comprise two sets of parallel tubes between them, arranged on either side of the movable contact.
  • these tubes extend substantially perpendicular to the movable contact.
  • the above-mentioned coolers are made of metal or ceramic.
  • Figures 1, 2 and 3 are three schematic sectional views, respectively illustrating three particular embodiments of the invention.
  • Figures 1a, 2a and 3a are schematic side views, illustrating the shape and the arrangement of the coolers corresponding respectively to FIGS. 1, 2 and 3.
  • a pole 1 of miniature circuit breaker comprising an insulating housing B, having on its front face an operating lever 2 and on its two narrow lateral faces 3, 4, connection terminals 5, 6.
  • Inside the housing B are housed, as is known per se, a movable contact 7 and a fixed contact 8.
  • the movable contact 7 is controlled by a control mechanism (not shown) connecting the aforementioned lever 2 to the contact mobile 7 for contact closure.
  • B are also housed a thermal release and electromagnetic release (not shown), susceptible cause, in the event of an overload or short-circuit, an automatic opening of the contacts.
  • the lower part of the housing B contains a breaking chamber 9 constituted by a first arc-forming chamber 10, communicating with the entry of a second chamber 11, known as arc extinction, comprising separators 13 constituted by a stack of plates (or sheets) which extend parallel to the base 12 of the housing B.
  • the movable contact 7 extends substantially perpendicular to the plane of the plates 13, of so as to draw an arc between the contacts 7, 8, during their separation, the direction of which initial is substantially parallel to the plates 13.
  • the aforementioned interrupting chamber 9 is laterally delimited by arc horns 14, 15 respectively connected electrically to the two aforementioned terminals 5, 6. These arc horns 14, 15 are arranged so as to capture the arc pulled between the contacts 7, 8 during their separation.
  • circuit breaker As such a circuit breaker is well known to specialists, it will be unnecessary to describe in more detail its arrangement or operation.
  • cooling elements 16 are placed around the movable contact 7 and are intended to cool the hot gases present around the movable contact 7 after the switching of the arc.
  • These coolers 16 are constituted by two sets 17a, 17b of plates 17 parallel to each other, said assemblies being disposed respectively on either side of the movable contact 7.
  • these cooling elements 16, or coolers are constituted by two sets 18a, 18b of tubes 18 parallel to each other, said assemblies 18a, 18b being arranged on either side of the movable contact 7.
  • these tubes 18, instead of being arranged around the movable contact 7, are placed in the arc-forming chamber 10, at a certain distance from said contact 7, for example at same distance between the separators 13 and the movable contact 7. It will be noted that in this case, the two sets of tubes 18a, 18b will be separated by a distance a greater than the width of the movable contact 7. In these three embodiments, the large exchange surface of the coolers 16 causes significant cooling of the gas.
