  • the arc quenching chamber 1 has a two-part Chamber housing 6 with a lower shaft body 7 and an end body that terminates this above 8 on.
  • the shaft body 7 In the shaft body 7 are mutually Distance between quenching plates 10 is arranged.
  • This quenching plate arrangement is on both sides by an arc guide rail 11 or 12 completed, the left Arc guide rail 11 with a small distance stationary arcing horn 13 faces and the right arc guide rail 12 at the lower end like this is angled that the movable Contact lever with its arcing horn 5 in the off position at the end of the bend.
  • the quenching plates 10 end close in one plane the upper end of the shaft body 7 and are against Longitudinal displacement through the end body 8 secured.
  • a left end web 16 and a right end web 17 are wider than the webs 15, namely such that the last baffle plate 10 and the subsequent one Arc guide rail 11 or 12 on the End bar 16 or 17 abut.
  • the webs 15 in connection with the end webs 16 and 17 form a first Barrier 20 for arcing gases that arise when switching and that before leaving the free environment are to be cooled and deionized.
  • the cross-sectional shape of the webs 15 and 21 is according to Figures 1 and 4 the same and approximately square shaped.
  • the width b and correspond Height h of the webs 15 and 21 approximately the pitch t the quenching plates 10.
  • a third barrier 24 is through an end wall 23 of the end body 8 is formed.
  • the front wall 23 contains the outlet openings 26 (FIG. 2), through which the cooled and deionized arc gases leave the arc extinguishing chamber 1.
  • the first and second barriers 20 and 22, respectively respectively have only a small mutual distance d ( Figure 4), which is about a quarter of the width b or the height h of the webs is 15 or 21, is between the second and the third barrier 22 or 24 a greater distance provided by which a cooling chamber 25 is formed becomes.

  • the webs 15 are the first barrier 20 on the edge side by a cross piece 27 connected with each other. This creates a contact surface also formed for those quenching plates 10 that do not rest against the webs 15 of the first barrier 20.
  • the outlet openings 26 are shorter than the openings formed by the webs 15 and 21.
  • the pitch of the outlet openings 26 is also different of the pitch t ( Figure 1) of the webs 15 and 21 chosen. This avoids a gap the webs 21 just an exit opening 26 faces.
  • the end body 8 protrudes on all sides Edge pieces 30, 31 and 32 and 33 for support on front end of the shaft body 7. Through holes 34 are in the corners of said edge pieces for connecting the end body 8 and the shaft body 7 provided by means of screws 35.
  • the contact lever is used to separate a circuit 4 from the extended position shown in the Position shown in broken lines is moved.
  • the resulting switching arc is switched off by the fixed contact 3 and the arcing horn 5 of the contact lever 4 on the arc guide rails 11 and 12 transferred. Due to magnetic and thermal The switching arc is buoyant then in the quenching plate arrangement (quenching plates 10, FIG 1) and is there in one of the number of quenching plates 10 corresponding number of partial arcs split. The until the switching arc goes out Arcing gases escape through the arrangement of barriers 20, 22 and 24 to the outside. there first practice the webs 15 due to the first barrier 20 their relatively high height and their parallel Flank a directional effect on the gas flow.
  • the partial flows of the gas then meet the lower ones Areas of the webs 21 of the barrier 22 and are due the small distance d between the webs 15 and 21 forced to deflect by about 90 °.
  • Space between two webs 21 of the second barrier 22 hit two redirected partial flows of the arc gases against each other and can space between the webs 21 only after redirection leave by 90 ° in the direction of the cooling chamber 25. This happens with vigorous vortex formation and expansion. This is associated with a strong cooling and one Recombination of load carriers.
  • the dwell time of the arc gases in the cooling chamber 25 is due to the dimensioning of the outlet openings 26 to influence Despite the good effectiveness the described arrangement of barriers 20, 22 and 24 the arrangement described claims only one relatively small part of the total height of the arc quenching chamber 1. Furthermore, no conductive Parts such as wire mesh, mesh made of expanded metal or Similar items needed to get the cooling you want and to effect deionization of the arc gases. Therefore, the described arc quenching chamber stands out 1 also through a great security against electrical flashovers on the exit side of the fire extinguishing plates 10 out. The safety distance to earthed Components are cut to a small size of around 20 - 60 mm decreased.
