Definitions
- the invention relates to a locking device according to the preamble of claim 1.
- Such locking devices are used so that only one of several low-voltage switching devices, in particular circuit breakers, can be switched on.
- DE 44 06 236 A1 discloses a locking device for at least two switching devices connected to one another by a flexible connecting element, in particular a Bowden cable, but also for switching devices in connection with plug-in units or door locks, the locking device assigned to each switching device having a neutral position, in which all switching devices are unlocked and has an active position caused by the respective switched-on switching device in which the other switching device is locked.
- the switching shaft of each switching device is operatively connected to a curved locking disk, against which a locking element connected to the respective end of the connecting element rests.
- the locking disk adjusts the connecting member via the linearly displaceable locking member so that the switching shaft of the other switching device, which is operatively connected to the associated locking disk, by its locking member at the other end of the
- Connecting member is held against rotation by the locking member lockingly engages in a hole in the locking disc.
- the invention is therefore based on the object of specifying a securely operating locking device with lower loading forces.
- the locking disk and the locking member which belong to the one switching device, are connected crosswise to the locking member and the locking disk, which belong to the other switching device, via a connecting member in each case.
- the locking device according to the invention Due to the locking engagement of the locking member on the switching shaft of the respective switching device via the associated locking disk, the locking device according to the invention is independent of the type of drive of the switching device, be it a rocker arm drive, a rotary drive or a motor drive. In the latter case, the lock also works in the event of a power failure.
- improper opening of the contact system of one of the switching devices for example as a result of welded switching contacts, effectively prevents the switching device from being switched on.
- the locking device according to the invention requires relatively low forces to act on the locking elements and, due to its self-positioning action, is relatively independent of tolerances of the means used, in particular of those of the flexible connecting members.
- the coupling of the selector shaft with the associated locking disk is advantageously designed by a driver pin which engages through a side wall of the switching device in the selector shaft.
- a driver pin which engages through a side wall of the switching device in the selector shaft.
- one half of the locking device is arranged in an insulating material housing to be connected laterally to the switching device.
- the insulating housing expediently consists of a shell-like part and a cover.
- the locking member is advantageously designed as a lever with two arms, on the one hand with which the associated connecting member and on the other hand the associated locking curve section cooperate.
- the associated switching shafts of the switching devices are loaded by the locking device in such a way that the dynamics of the associated contact systems are negatively influenced.
- other spring elements interacting with the locking disks which have a positive effect on the course of movement of the selector shafts and thus the switching dynamics of the switching devices due to a dead center behavior.
- the operative connection of the blocking elements with one or more auxiliary switches is advantageous. In this way, for example, a message about the state of the switching devices or the locking device and / or an additional, electrical locking of motor drives for the switching devices can be implemented at a remote location.
- FIG. 1 of the associated drawing shows a locking device according to the invention connected to two low-voltage switching devices, preferably circuit breakers, in a broken-section illustration.
- the locking device 1 consists of two identical device halves 10a and 10b which are flexible via two Bowden cables
- the two switching devices 2a, 2b indicated by broken lines are located in front of the device halves 10a and 10b, respectively, with respect to the plane of the drawing and are shown in the switched-off state.
- Each device half 10a or 10b is enclosed by an insulating housing 1 2, which consists of a shell-like part 1 3 and a cover 14 to be connected to it via screw connections 15, which in turn is attached laterally to the switching device 2a or 2b via further screw connections 16 is.
- a locking washer 1 7a or 1 7b and a locking member 1 8a or 1 8b are mounted in the insulating material housing 1 2 of each device half 1 0a or 10b.
- the locking disc 1 7a or 1 7b is mounted centrally in an axis of rotation 19 and carries a driver 20 which extends through an elongated bent opening 21 of the cover 14 and through an opening of this type in the side wall of the switching device 2a or 2b and engages in a lateral portion of the rotating control shaft of the associated switching device 2a or 2b, whereby a coupling of the control shafts with a locking disk 1 7a or 1 7b is produced.
- the locking member 1 8a or 1 8b is a two-armed lever mounted about a central pivot axis 22, each with a first lever arm 23a or 23b and a second lever arm 24a or 24b.
- the first connecting member 1 1 a is attached eccentrically to the locking disc 1 7 a of one device half 10 a and with the other end to the first lever arm 23 b of the locking member 1 8 b of the other device half 10 b.
- the second connecting member 11b is attached eccentrically to the locking disk 17b of the other device half 10b at one end and to the first lever arm 23a of the locking member 1 8a of the one device half 10a at the other end.
- the second lever arm 24a or 24b of the locking member 1 8a or 1 8b is located at the end in the area of action of a locking curve section 25a or 25b of the associated locking disk 1 7a or 17b.
- switching device 2a is to be switched on, for example.
- the switching shaft of the switching device 2a rotates clockwise and thus also the locking disk 17a due to the coupling via the driver 20.
- the first connecting member 1 1 a is acted upon in the direction of arrow F and causes the other switching device 2 b to be pivoted
- Locking member 1 8b counterclockwise, causing its second lever arm 24b reaches the area of the locking curve section 25b of the associated locking disk 17b. If an attempt is now also made to switch on the other switching device 2b, then the intended switching-on movement of its switching shaft is effectively blocked, since the switching shaft of the switching device 2b is coupled to the locking disk 1 7b, which in turn comes into locking engagement with the second lever arm 24b of the locking member 1 8b and is prevented from further clockwise rotation.
- the locking device 1 accordingly prevents that after switching on one of the switching devices 2a or 2b, the respective other switching device 2b or 2a can also be switched on.
- Auxiliary switches 32 are arranged in the vicinity of the blocking member 1 8a and 18b and are operatively connected to the second lever arm 24a and 24b. Depending on the position of the blocking elements 24a and 24b, the auxiliary switches 32 assume corresponding switching states, which are used elsewhere as signaling and / or
- Command signals can be processed further.
- the locking member 1 8a or 1 8b is acted upon by a first spring element 26 against the direction F of its tensile loading by the second connecting member 1 1 b or 1 1 a.
- the first spring element 26, designed as a helical compression spring, is supported between a support 28 formed in the shell-like part 1 3 of the insulating material housing 1 2 and the first lever arm 23a or 23b of the locking member 1 8a or 1 8b.
- the effect of the first spring element 26 is that in the one device half 10a or 10b of the locking device 1 in the rest position shown, the locking member 1 8a or 1 8b is pivoted away from the locking curve portion 25a or 25b of the associated locking disc 1 7a or 1 7b and thus via the operative connection with the connecting member 1 1 b or 1 1 a of the locking curve section 25b or 25a of the locking disc 1 7b or 1 7a in the other device half 1 1 b or 1 1 a safely from the second lever arm 24b or 24a the associated locking member 1 8b or 1 8a is turned away.
- the spring elements 26 are designed with regard to their spring force so that they in the switched-off position of the switching device 2a or 2b, act on the locking member 1 8a or 1 8b clockwise in such a way that its second lever arm 24a or 24b actuates the auxiliary switches 32, the actuating plungers of which are acted upon by an opposing spring force.
- the locking disc 1 7a, 1 7b is acted upon by a second spring element 27.
- the second spring element 27, which is designed as a helical compression spring, is mounted on a spring plunger 29 which is supported between a plunger guide 30 formed in the shell-like part 1 3 and a peripheral pin 31 of the locking disk 1 7a or 1 7b.
- the spring plunger 29 is arranged such that when switching device 2a or 2b is switched on or off, the
- Pin 31 passes through the imaginary connecting line between the axis of rotation 1 9 of the locking disk 1 7a or 1 8a and the tappet guide 31 and thus a point of maximum application of force.
- the locking disc 1 7a or 17b thus forms a dead center system with the second spring element 27, which has the purpose of relieving the switching shaft of the associated switching device 2a or 2b when negative locking effects of the locking device 1 are switched on.
