Furthermore, of the Netherlands derwoods circuit breaker 1 more arc extinguishing chambers 4 and supported on a supporting structure 5 Antriebsme- mechanism 6, which is not shown by a, in the front half-shell 2 of the housing to be fastened Abdeckhau ⁇ be coverable is.
- the support bolts 10, 11 serve to fasten a housing 12, shown in more detail in FIG. 3, of a spring accumulator 13 of the drive mechanism 6.
- the drive mechanism 6 is used to Actuate the supply ⁇ a movable contact 15, the plurality of supported in a pivotable contact support 16 and arranged in parallel contact lever 17 (in the figure is only a contact lever visible) has.
- the contact lever 17 are pivotally mounted in a known manner by means of a hinge pin 18 in the contact ⁇ carrier 16 and biased by two contact ⁇ force springs 19.
- Flexible conductors 20 are used to connect the contact lever 17 with a lower connection Rail 21.
- the fixed contact 22 assigned to the movable contact 15 of the contact arrangement is connected to an upper connection rail 23.

- tensioning shaft 9 which is rotatable by means of a manual drive 31 which is shown in more detail in FIGS . 4 to 11.
- the manual drive 31 consists of two Trag ⁇ plates 32 (in the figures, only one is visible), a ratchet wheel 33, a transport pawl 34, a pawl 35 and coupled to the transport pawl assembly 36 for actuating the transport pawl.
- the support plates 32 of the manual drive are held by means of the clamping ⁇ shaft 9 and the support pin 10 fixed to the supporting structure.
- the ratchet wheel 33 is fixedly arranged on the tensioning shaft 9. net.
- the pawl 35 is held by means of a first Distanzbol ⁇ zen 37 pivotally mounted on the support plates 32 of the manual drive 31 and biased by a first pressure spring 38 resiliently against the ratchet wheel 33.
- the arrangement 36 for actuating the transport pawl 33 consists of an actuating means 39 in the form of a clamping lever and a coupling strand 40 for coupling the clamping lever to the transport pawl.
- the stationary pivot bearing for the clamping lever is formed by the support pin 10.
- the coupling strand 40 has a first lever 41, which is articulated to the tensioning lever by means of a slot / pin connection 30, and two second levers 42 pivotable about the axis of rotation of the ratchet wheel (only one is visible in the figures), wherein the transport pawl 34 a second Ab ⁇ stand bolt 43 is pivotally supported on the second levers 42 and biased by a second pressure spring 44 is also resiliently against the ratchet wheel 33.
- a support lever 45 is attached to which a pawl lever 46 pivotally articulated about a stationary pivot axis 47 in the form of a pin and spring 49 is biased by a Tot Vietnamesefeder 48 against a guide surface 49 of the clamping lever.
- the dead center is thereby count ⁇ supported on a first arm 50 of the pawl lever 46 ⁇ that the spring force of the dead center spring 48 initially ent ⁇ counterclockwise acts on the pawl lever.
- the guide surface 49 has a recess 52 whose neneat In ⁇ form a first recessed portion 53 and a protruding second portion 54th
- the pawl lever 46 which is pivotable about the fixed pivot axis 47 and supported on the dead center spring 48, has a second arm 55 which cooperates with the guide surface.
- the actuating means 39 in the form of the clamping lever during a first tightening phase (Spann ⁇ hub according to the figures 4 to 8) against the force of two return springs 56 from a rest position (see FIG. 2) in an end position (see FIG. Figure 8) and in a second operating phase (return stroke according to Figures 9 to 11) under the force of the return springs 56 from the end position back into the rest position can be transferred.
- a free end of the return springs 56 engages in a bore 57 of the Betuschistsmit- means 39, while the other free end is supported on one of the support plates 32.
- Figures 4 to 8 show the sequence of movements of the assembly for actuating the transport pawl during the first actuating phase, ie during the clamping stroke of the means of Betuschistsmit ⁇ .
- the second arm 55 of the Klin is ⁇ kenhebels initially under the force of the dead center 48 at a curved portion 58 of the guide surface on.
- the transport pawl 34 drives the ratchet wheel 33 and thus the tensioning shaft 9 revolves entge ⁇ gen-clockwise.
- the spring accumulator 13 is stretched a little way, as described in detail in the document DE 101 20 783 Cl.
- FIG. 6 shows the actuating means 39 in a first intermediate position, upon reaching which a projecting edge 59 of the second arm 55 of the ratchet lever in the AusOSE- mung 52 and thus engages the path of movement of the recessed first portion 53. If the clamping stroke is broken off in this phase, then a turning back of the actuating means 39 in the direction of the rest position is no longer possible, since the latch lever blocks the actuating means in a clockwise direction as a result of engagement with the recess 52.
- the projecting edge 59 of the pawl lever further slides out of the path of travel of the recessed portion 53 along the projecting portion of the guide surface.
- the ratchet lever In a second intermediate position of the actuating means 39, the ratchet lever then assumes a position in which the dead center of the dead center 48 is exceeded and thus the spring force of the dead center acts in the opposite direction on the ratchet lever.
- the latch lever succeeded ge ⁇ Telss the figure 8 in abutment with a first stop 60.
- This first stop 60 is formed by a pin which is fixed to the support lever 45 and also forms the abutment for the dead-center 48th
- the pawl 35 Upon reaching the end position of the actuating means 39 according to the figure 8, the pawl 35 engages in a recess between two teeth of the ratchet wheel and thus blocks the ratchet wheel in a clockwise direction.
- This No ⁇ cken 62 extends over two teeth and projects in Radia ⁇ ler direction of the ratchet wheel, the outer edge of the teeth ⁇ art that the transport pawl 34 on the eighth return stroke, ie in the second actuation phase, from the path of movement of the teeth and not can engage in the recess between these two teeth overlapped by the cam 62.
- This itatior ⁇ gan 65 signals shortly before the end of the eighth clamping stroke, that the spring accumulator 13 is fully cocked.
- a pickup roller 67 of a roller lever 68 is of the lever system 29, however, is not decoupled from the circumferential edge of a cam 69 pelt, so that the spring accumulator 13 can not be latched in its cocked position.
- the circuit breaker 1 is therefore not ready to start.
- the first intermediate position of the actuating means 39 in the form of the clamping lever is selected so that it is reached at the eighth clamping stroke before the indicator 65 siert signali ⁇ that the spring accumulator 13 is fully tensioned.
- the clamping lever Interrupted the operator of the clamping lever after reaching the first intermediate position, the clamping stroke, the clamping lever is blocked against turning back to its rest position. The operator is thereby indicated by the standing in space cocking lever that he has not completed the clamping stroke.
- the second intermediate position is selected so that the Spannhe ⁇ bel is only released again when the roller lever 68 is decoupled from the peripheral edge of the cam 69 and there ⁇ actually latched with the tensioned spring accumulator 13.
- a blocking of the actuating means 39 in the form of Spannhe ⁇ lever takes place with advantage not only at the eighth (last), but also at every other clamping stroke, so that the operator of the actuating means 39 is prevented from performing one of the Spannhü ⁇ be incomplete.
