Definitions
- the invention relates to a protective switching device designed for connection to devices with an additional function, for example a residual current circuit breaker and undervoltage release, which causes a coupling to be switched off by a driver, in accordance with the generic term of claim 1.
- the protective switching device has a jamming point between a pawl and a release lever.
- a residual current circuit breaker is connected to a circuit breaker, for example in the form of a circuit breaker, it must be ensured that the circuit breaker cannot be switched on if the residual current circuit breaker is not switched on and is therefore activated.
- the contacts of the protective switching device are allowed to approach to some extent before they are then connected to one
- Residual current circuit breaker in the switch-off position diverge again by a release latch.
- the invention is based on the object of developing a connectable protective switching device in which, in the case of a connected residual current circuit breaker in the switched-off position, the contacts fail to approach when the protective switching device is switched on.
- the driver moves in the switched-off position of the attachment, for example a residual current circuit breaker, directly or indirectly giving a distance between the pawl and release lever element so that the latching of the protective switching device is prevented.
- a residual current circuit breaker is in the open position and an attempt is made to switch on the circuit breaker, the contacts are prevented from approaching. This avoids possible danger from a contact flashover.
- the protective switching device should understandably prevent a re-switching via the coupled protective switching device in the case of a connected residual current circuit breaker that has been triggered and has been brought into the switch-off position. If the attempt is made to restart, the contacts do not approach.
- a switch lock with the following structure: its pawl guides a movable contact arm indirectly or directly in a portable bearing.
- the release lever is arranged in a fixed bearing and supports the movable contact arm in the open position of the manual control element.
- a coupling rod is connected to the pawl to form a pivotable manual control element in another portable storage facility.
- the spacer element can be arranged on the pawl such that it can rotate about the bearing for the coupling rod, the spacer element being in contact with the release lever in the switched-off position of the driver and in the switched-off position of the protective switching device and preventing latching.
- the driver is arranged outside the geometric locations of the coupling rod and the pawl bearing in the previously described switching lock.
- the driver can advantageously form an eccentric which deflects the spacer element, which can be designed as a two-armed lever, one arm of which can be at a distance from the release lever, and on the other arm in the off position of a residual current circuit breaker, the driver has a deflecting effect.
- a protective switching device For highly mechanized production, it is advantageous to design the fault elements required and customary in a protective switching device as leaf springs. Such leaf springs can be easily manufactured and assembled at high speed in a production line.
- the described protective switching device has the further advantage that it is compatible with the series on the market.
- FIG. 1 shows a protective switching device in an indicated housing with a switch lock, a pair of contacts, a pivotable manual control element and a driver. Latches, electrical and thermal, are omitted for the sake of clarity, as are common contact and switching springs.
- FIG. 1 illustrates how the latching is prevented from the switch-off position and when a residual current circuit breaker is triggered.
- the switch-off position of the protective switching device is shown in the representation according to FIG. 1 when the driver is in a position as it is when the attachment is switched on, e.g. a residual current circuit breaker or without a connected and possibly attached residual current circuit breaker, takes its rest position.
- FIG. 3 shows the switch-on position of the protective switching device under the conditions for FIG. 2.
- the protective switching device 1 according to FIG. 1 is designed so that it can be attached to an attachment, for example a residual current circuit breaker, behind the drawing level, for example.
- a driver 2 causes a disconnecting coupling from a connected fault current circuit breaker.
- the protective switching device 1 has a locking point between a pawl 3 and a release lever 4.
- the driver 2 moves in the off position of a residual current circuit breaker directly or indirectly a distance between the pawl 3 and release lever 4 element 5 such that the latching is prevented.
- the driver 2 acts upon the distance-giving element 5 with a cam 6 acting as an eccentric when rotating counterclockwise by approximately 70 °.
- the spacing element 5 holds the release lever in the exemplary embodiment so far from the latch nose 7 that a latching cannot take place.
- the pawl 3 guides a movable contact arm 9 in a portable bearing 8, specifically in the exemplary embodiment.
- the release lever 4 is arranged in a fixed bearing 10.
- the axis 10 of the release lever 4 supports the movable contact arm 9 in a partial recess 11 according to FIG. 4 n in the open position of the manual control element 13.
- the pawl 3 is connected via a coupling rod 12 to a pivotable manual control element 13 in another portable bearing of the pawl.
- the driver 2 guides a separate spacer element 5 with regard to its movement.
- the movable contact arm 9 and a fixed contact 15 form a contact pair which has contact pieces 16 in practice.
- the driver 2 is shown in the off position caused by a residual current circuit breaker, if it has responded.
- the protective switching device 1 in turn is also shown in the off position. 2 shows the driver 2 in its rest position or in the case of a residual current circuit breaker which has not been tripped.
- the protective switching device is also shown in FIG. 2 in the switched-off position from the manual control element 13.
- FIG. 3 shows the switch-on position of the protective switching device 1 for the rest position of the driver 2 or when the residual current circuit breaker is not tripped.
- the spacer 5 is rotatably arranged around the bearing 14 for the coupling rod 12 on the pawl 3.
- the spacer element 5 prevents the latching in the switched-off position of the driver 2, according to FIG. 1, and in the switched-off position of the protective switching device, in that it bears against the release lever 4 in the switched-off position in the exemplary embodiment according to FIG.
- the driver 2 according to FIGS. 1 to 3 is arranged outside, above the geometric locations of the coupling rod 12 and the pawl bearing 8, 14. Above it is to be understood in relation to the fact that a contact piece 16 on the moving contact 9 is considered to be below.
- the arrangement outside of the geometric locations improves compatibility with different series of devices.
- the driver 2 can form an eccentric which rests on the spacer 5 in the form of a two-armed lever.
- One arm 17 of the spacer element 5 is in contact with the release lever 4 at a distance.
- the driver 2 is deflecting with its cam 6 or with its eccentric profile.
- the portable bearing 8 of the pawl 3 is connected to the fixed bearing 10 of the release lever 4 by a coupling means 19, which is spherical in the exemplary embodiment.
- the usual spring means for contact force, energy accumulator and manual control element are omitted in FIGS.
