Definitions

  • the invention relates to a multi-pole, in particular three-pole, low-voltage circuit breaker with a switching shaft common to all poles, with pole units composed of at least two switching chambers each and with a drive device common to all pole units.
  • a circuit breaker of this type is known for example from DE-A-35 42 746.
  • the construction of circuit breakers evident from this and from other patent documents can in principle be used for circuit breakers with an enclosed nominal current. It is known to design circuit breakers for a very high rated current, which can exceed 4000 A, by a combination of modules that are dimensioned for a low rated current. This applies in particular to the actual current-transmitting parts, such as contact systems and arc quenching chambers.
  • a circuit breaker constructed in this way is described in EP-A-0 320 412.
  • a feature of the modular circuit breaker that has been expanded to include a high rated current is its width, which may be significantly larger than that for versions with lower rated currents. This brings with it the problem that normal and otherwise non-disturbing dimensional deviations of the assembled components occur, which can impair the function of the circuit breaker or even prevent it from being properly assembled.
  • the invention is based, both when assembling the components of the switch and when the switch interacts with an insertion frame, the task to resolve difficulties arising from dimensional deviations.
  • the switching shaft as an important component for the function of the circuit breaker, can not only be manufactured more easily, but due to the subdivision it becomes largely insensitive to dimensional deviations in the longitudinal direction and to errors in the mutual alignment of the pole units.
  • the circuit breaker therefore always has a width which is only affected by the tolerance of one part, namely the carrier.
  • the coupling bolts can also form the connection with insulating couplers, which are used for Transfer the movement of the switching shaft to the contact arrangements of the pole units of the circuit breaker.
  • Figure 1 shows a three-pole low-voltage circuit breaker in a front view with the control panel removed.
  • FIG. 1 A shift shaft composed of shaft sections according to FIGS. 2, 3 and 4 with levers and coupling bolts seated thereon is shown in FIG.
  • FIG. 6 shows a detail in the area of the connection of two shaft sections.
  • FIG. 7 shows a detail of an intermediate wall arranged between two pole units of the circuit breaker shown.
  • the circuit breaker 1 according to FIG. 1 has a switching shaft 2 which is common to all pole units 9 composed of switching chambers 3 and which accordingly extends over the entire width of the circuit breaker 1.
  • the pole units 9 are accommodated in a supporting structure 5 provided with side walls 4 together with a drive device 6 which has an actuating handle for tensioning a spring accumulator.
  • the spring mechanism can be tensioned by a motor, as is known per se.
  • An indicated slide-in frame 8 carries on its inside rails 10 for casters 11 attached to the side of the circuit breaker 1.
  • a driving device 12 fastened to the side of the drive device 6 in the supporting structure 5 has a bearing block 13 and a travel shaft 14 which also extends over the entire width of the circuit breaker 1 on the ends of which project beyond the side walls, a link lever 15 is fastened, which cooperates with a bolt hidden by the casters 11 and serving as a stationary abutment.
  • the bearing block contains a threaded spindle 16, one end of which is accessible for operation on the front side of the circuit breaker 1.
  • the supporting structure 5 has a support 20 which can be formed in one or more parts and which extends over the entire width of the circuit breaker 1.
  • the carrier 20 is dimensioned such that it corresponds to the sum of the width of the pole units 9, including a required mutual distance and the highest possible oversize that the arrangement mentioned can have due to tolerances.
  • the outer side closure of the structure 5 form the already mentioned side walls 4, which are therefore normally at a certain distance from the outer pole units 9.
  • the circuit breaker 1 has a width which is independent of the dimensional deviations of the switching chambers and of the pole units 9 composed of them and is determined only by the supporting structure 5. This ensures in particular that the rails 10 and castors 11 can cooperate reliably.
  • the selector shaft 2 is composed of three shaft sections 21, 22 and 23, the design of which can be seen in more detail in FIGS. 2, 3 and 4.
  • the shaft section 21 is designed as a central section which can be coupled to the left shaft section 22 and to the right shaft section 23.
  • the shaft section 21 has a central pin 24 at each end and a lever 25 near the pin, which has a through hole 26 for a coupling pin 35.
  • the left shaft section 22 and the right shaft section 23 are designed as mirror images and each have a central opening 27 at their end facing the middle shaft section 21 and a lever 30 with a through hole 31 for a coupling bolt 35 near this opening.
  • the left one and the right shaft section is visible, while the middle shaft section 21 is covered by the upstream drive device 6.
  • All described shaft sections 21, 22 and 23 are further provided for connection to the contact systems of the switching chambers 3 with further levers 32 through which the coupling bolts 35 extend ( Figure 1).
  • the coupling bolts 35 grip insulating couplings 34 in a known manner, through which the contact arrangements in the pole units 9 can be actuated.
  • the described design of the control shaft 2 and the supporting structure 5 enable an uncomplicated assembly of the circuit breaker 1 from its essential assemblies.
  • the drive device 6, the pole units 9 and the supporting structure 5 can be provided as prefabricated structural units.
  • the shaft sections 21, 22 and 23 are located in the pole units 9 and are now roughly centered against one another by simply plugging them together. Then the coupling bolts 35 mentioned are inserted into the levers 25 and 30.
  • the circuit breaker 1 is closed off from the outside in width by the mentioned side walls 4, which have a certain distance from the side walls of the outer pole units 9.
  • FIG. 5 only the three previously described aligned shaft sections 21, 22 and 23 with the levers 32 seated thereon are shown. As can be seen, the coupling bolts 35 are longer than the associated shaft sections 22 and 23, such that the coupling bolts 35 pass through all the levers 30 and 32 seated on the shaft sections 22 and 23 and additionally the lever 25 of the subsequent central shaft section 21.
  • a shorter bolt 37 extends, which only establishes the connection with the insulating coupling 34 of the middle pole unit 9. Because the coupling bolts 35 extend through a plurality of levers, their play with respect to these levers and, accordingly, the play of the entire coupling is very small. However, misalignments of the shaft sections 21, 22 and 23 are bridged because only one or two levers are detected in the subsequent shaft section. For the safe transmission of a large torque, it is important that the coupling bolts engage with a radius with respect to the shaft axis caused by the levers 25, 30 and 32.
  • the shaft arrangement is not only supported at the ends, but also in the area of the coupling points. Details can be found in FIG. 6, which shows an enlarged view of the detail marked with a dash-dotted circle in FIG.
  • the shaft sections 21 and 23 penetrate an intermediate wall 38 in the supporting structure 5 of the circuit breaker 1.
  • the coupling bolt 35 passes through the intermediate wall 38 7
  • the intermediate wall 38 is provided with an arcuate opening 42, which only covers approximately 60 ° when switching, in accordance with the limited pivoting angle of the shaft arrangement.
  • FIG. 5 also shows drive levers 43 which transmit the drive force from the drive device 6 (FIG. 1) to the selector shaft 2.
