Definitions
- the invention relates to a low-voltage circuit breaker with a contact arrangement, one Drive device for actuating the contact arrangement and with a control shaft for the transmission of a driving force of the drive device on the contact arrangement and one the shift shaft receiving bearing assembly.
- Low voltage circuit breakers consist of several, the Assemblies adapted to different subtasks the manufacture of the circuit breakers become.
- the largest assemblies, or units, form the switching poles, that is, those of fixed and movable switching contacts with existing contact systems their support insulation and components for connection to a for several such switching poles common drive device.
- the drive device provided motion sequences via a stationary mounted control shaft on all existing contact systems transfer. So far, the shift shaft has been designed as Treated part of the drive device.
- DE-PS 44 16 090 shows a bearing arrangement for a Switching shaft of a multi-pole electrical switching device with a structure formed from parallel walls. This points Shaft bearings with half shells.
- DE-OS 42 27 352 is one for the pole units formed from the interrupters common, selector shaft shown, consisting of shaft sections is composed according to the pole units. The pole units rest on a carrier which corresponds to the largest width of the pole units is dimensioned.
- Further Representations of power transmission systems for the Actuation of switching contacts are in DE-PS 28 35 879 and DE-OS 27 26 489 described. All of these described Construction methods have been used to manufacture the individual Modules have proven their worth, but they have the disadvantage on that a functional test only in the fully assembled State of the switch is possible.
- the invention is therefore based on the object, the test to make it easier and more time to fix Reduce errors.
- it should be checked whether the path provided by the drive is the correct one Closing the contact arrangements with the required Contact force causes
- this object is achieved in that the bearing arrangement for the selector shaft with at least one a pole assembly receiving the contact arrangement connected bearing body.
- the "switching pole" module becomes full functional and can therefore be checked easily before the switch is fully assembled.
- the integration of the selector shaft in the "selector pole” module through the use of at least three bearing bodies, from which the central or middle main bearing body itself has known additional elements, in particular springs to provide a restraining force, end stops, a Bounce barrier and elements for the consumption of residual energy.
- This middle main bearing body is advantageous with a Wall of the pole assembly through a combination of form and non-positive elements connected. That can be useful two or more plug-in feet in connection with corresponding Pockets in the wall of the pole assembly and Centering pin with internal thread, the middle Main bearing body opposite the wall of the pole assembly and align with the drive device.
- the selector shaft ends with two auxiliary bearing bodies based on the expedient in the same or similar manner are attached, but none or only a part of the have additional functions mentioned.
- the production and the assembly of the selector shaft can be done by a subdivision the control shaft into two symmetrical sections be relieved.
- the synchronous drive of the sections is secured by a coupling bolt on both Parts of the shift shaft seated lever penetrated.
- the advantage of the split control shaft is that the Parts are supported in two storage locations. The Art the storage is therefore statically determined and thus Can be carried out with little play. A possible misalignment will without influencing the friction conditions through the clutch balanced.
- the main bearing body is with an abutment for retaining springs provided, preferably in one piece on the main bearing body is molded.
- the retaining springs can already move forward the assembly of the bearing assembly attached to the main bearing body his.
- the retention springs are housed in a space-saving manner and engage advantageously in the manner of a dead center or Dead center system on the gearshift lever. The reduces the impact on the main energy storage of the Switch drive.
- Figure 1 shows schematically the arrangement of the selector shaft in the assembly "switching pole", in the side view, at closed contact arrangement.
- FIG. 2 shows schematically the arrangement according to FIG. 1, with the contact arrangement open.
- FIG. 3 schematically shows a front view of the Arrangement according to FIG. 1.
- FIG. 1 and 2 the arrangement of the central or middle main bearing body 1 with the selector shaft 2 shown.
- This middle main bearing body 1 is with a Wall 3 of the pole assembly 4 through two plug-in feet 5 in Connection with corresponding receiving pockets 6 in the wall 3 the pole assembly 4 and centering pin 7 with internal thread, the main bearing body 1 against the wall 3 of the pole assembly 4 and compared to that indicated in FIG. 1 Align drive device 20, connected.
- the shift shaft 2 near its ends supported by two auxiliary bearing bodies 8 and 9, which also are attached by means of plug-in feet 10 and 11.
- the selector shaft 2 is in Form of two symmetrical sections 2a and 2b, those on their domes with levers 13 and 14 are provided, which are interconnected by a coupling bolt 12 are connected, these on the two sections 2a and 2b of the control shaft 2 seated levers 13 and 14 penetrated.
- the main bearing body 1 is with an abutment 15 for the Retaining springs 16 provided in one piece on the main bearing body 1 is molded.
- the coupling bolt 12 is arranged pivotable catch hook 17, which behind catch elements 18 during the switch-off process hook and so bouncing the contact assembly 19th prevent.
- control shaft 2 The arrangement of a control shaft 2 described is suitable especially for multi-pole circuit breakers. With these are the pole assemblies 4 as shown in FIGS. 1 and 2 are shown side by side and are common actuated by the control shaft 2. Instead of single-pole pole assemblies can also be a coherent three, four or Multipole pole assembly may be provided.
- the advantages of the invention are that an examination the interaction between drive, selector shaft and Switch pole before final assembly of the switch is made possible. If an error is found, it is not required, the finally assembled assemblies disconnect again to replace the faulty assembly. The time it takes to troubleshoot will thus significantly reduced. This is particularly the case with multipole circuit breakers advantageous.
