Definitions
- the invention relates to a multi-pole low-voltage circuit breaker with a common for all poles
- Switching shaft 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-3542 746.
- the construction of circuit breakers evident from this and from other patent documents can in principle be used for circuit breakers with an additional nominal current. It is known to have circuit breakers for a very high level
- a feature of the circuit breaker which is expanded in a modular manner to a high rated current, is its width, which may be significantly larger than that of the designs for lower rated currents. This brings with it the problem that normal and otherwise non-disturbing dimensional deviations of the assembled components occur in sum, 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 insert, the task frame to overcome difficulties arising due to dimensional deviations.
- this object is achieved in that the selector shaft is divided into shaft sections according to the number of pole units,
- the shaft section of the central pole unit has at both ends a central pin and a lever fastened close to the pin with a through hole for receiving a coupling pin, and
- the lateral shaft sections adjoining the central shaft section have, at their end facing the central shaft section, a central opening provided for receiving the central pin and near the central opening also have a lever with a through hole for receiving the coupling bolt.
- 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 is largely insensitive to dimensional deviations in the longitudinal direction and to errors in the mutual alignment of the pole units.
- the overall width of the circuit breaker can also deviate considerably from a desired value.
- This problem which is particularly disruptive when the circuit breaker interacts with a slide-in frame, can be remedied according to a further development of the invention in that
- the supporting structure of the circuit breaker has a support which is suitable for the entire width of all pole units, including one due to tolerances. giving maximum oversize, and
- the circuit breaker therefore always has a width which is only affected by the tolerance of one part, namely the carrier.
- a drive shaft extending transversely to its direction of travel and laterally projecting beyond the side walls and provided with link levers is arranged in the circuit breaker, and
- the drive shaft is mounted in the pole units and openings in the side walls are interspersed with play.
- a special low-play coupling of the shaft sections which at the same time ensures the desired compensation of misalignments, can be achieved in that
- the shaft sections each have at least one further lever, and - The coupling bolts each penetrate at least one of the additional levers of the lateral shaft sections.
- the coupling bolts can simultaneously 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.
- An intermediate wall is arranged between the pole units in the structure, and
- a bearing bush for the central pin of the central shaft section is supported, in the intermediate wall an arcuate opening adapted to the pivot angle of the switching shaft when switching is provided for the passage of the coupling bolt.
- 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 arrangement arranged between two pole units of the circuit breaker. wall 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 drive rollers 11 attached to the side of the circuit breaker 1.
- a drive device 12 fixed to the side of the drive device 6 in the supporting structure 5 has a bearing block 13 and also extends over the entire width of the circuit breaker 1 Travel shaft 14, on the ends of which project beyond the side walls, a link lever 15 is fastened, which cooperates with a bolt that is concealed by the casters 11 and serves 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, which the arrangement mentioned can have due to tolerances.
- the outer side closure of the support Works 5 form the already mentioned side walls 4, which are thus 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 formed 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 both ends 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, near this opening, a lever 30 with a through hole 31 for a coupling bolt 35 the left and right shaft sections are 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.
- the coupling bolts 35 mentioned are then 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.
- the coupling bolts 35 are longer than the associated shaft sections 22 and 23, such that the coupling bolts 35 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 push through.
- 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 pass through an intermediate wall 38 in the supporting structure 5 of the circuit breaker 1.
- the coupling bolt 35 passes through the intermediate wall 38
- the intermediate wall 38 according to FIG. 7 is provided with an arcuate opening 42 which, according to the limited pivoting angle of the shaft arrangement, only covers about 60 ° when switching.
- FIG. 5 also shows drive levers 43 which transmit the drive force from the drive device 6 (FIG. 1) to the selector shaft 2.
