Definitions
- the invention relates to a locking device according to the preamble of claim 1.
- Such locking devices serve that only one of several low-voltage switchgear, in particular Circuit breakers that can be turned on.
- DE 44 06 236 A1 discloses a locking device for at least two with each other by a flexible link, in particular Bowden cable, connected switching devices, but also for in connection with Inserts or door interlocks standing switching devices known, wherein the locking device assigned to each switching device neutral position in which all switching devices are unlocked and one by the respective switched-on switching device brought about an active position in which other switching device is locked.
- the switching shaft of each switching device is in operative connection with a curved locking washer a locking member connected to the respective end of the connecting member is applied.
- the locking disk adjusts when the switching device is switched on the connecting link via the linearly displaceable locking link, that the control shaft operatively connected to the associated locking disk of the other switching device by its locking member at the other end of the Link is held against rotation by locking the locking member engages in a hole in the locking disc.
- the invention is therefore based on the object of a securely operating locking device to be indicated with lower application forces.
- the locking washer and the locking member, which to the one switching device belong, are crosswise via a connecting link with the locking member or the locking disc belonging to the other switching device, connected.
- the locking device according to the invention is independent of the type of drive of the switching device, be it a rocker arm drive or a rotary drive or a motor drive. In the latter case, the lock works even in the event of a power failure. Improper opening also causes the contact system of one of the switching devices, for example as a result of welded Switch contacts that the switching on of the other switching device is effectively prevented.
- the invention Locking device requires relatively low forces to act of the locking elements and is due to their self-positioning effect relatively independent of tolerances of the means used, in particular of those of the flexible links.
- the coupling of the selector shaft with the associated one is advantageous Locking disc through a driver pin that runs through a side wall of the switching device engages in the switching shaft. It is advantageous if one half of the locking device in a side with the Switching device to be connected insulating material housing is arranged.
- the insulating housing expediently consists of a shell-like part and a lid.
- the locking member is advantageously designed as a lever with two arms with which on the one hand the associated link and on the other hand the associated Blocking curve section interacts.
- the locking device, the associated Switching shafts of the switching devices are loaded in such a way that the dynamics the associated contact systems is adversely affected.
- the locking members it is advantageous to the locking members in to promote beneficial senses with one spring element each. In the same Advantageous senses act, interacting with the locking disks Spring elements, the dead center behavior of the movement of the switching shafts and thus the switching dynamics of the switching devices influence positively.
- the operative connection of the locking members with each is advantageous one or more auxiliary switches. This can be used, for example, on a remote Make a message about the status of the switching devices or the locking device and or or an additional electrical lock of motor drives for the switching devices.
- the locking device 1 consists of two identical device halves 10a and 10b, which have two flexible Bowden cables Links 11a and 11b connected and each to a switching device 2a and 2b are attached laterally.
- the two by interrupted Lines indicated switching devices 2a, 2b are in the drawn Representation with respect to the drawing level in front of the device halves 10a and 10b and are shown in the switched-off state.
- Each device half 10a and 10b is enclosed by an insulating material housing 12, that of a shell-like part 13 and one with this over Screw connections 15 to be connected cover 14, which in turn via further screw connections 16 on the side of the switching device 2a or 2b is attached.
- each device half 10a or 10b Locking disc 17a and 17b and a locking member 18a and 18b mounted.
- the locking disk 17a or 17b is centered in an axis of rotation 19 stored and carries a driver 20, which is bent by an elongated Opening 21 of the lid 14 and through such an opening in the side wall of the switching device 2a or 2b extends and into a side Part of the rotating control shaft of the associated switching device 2a or 2b engages, thereby coupling the switching shafts with one locking disk each 17a and 17b is produced.
- the locking member 18a or 18b is a two-armed lever, each mounted about a central pivot axis 22 a first lever arm 23a or 23b and a second lever arm 24a or 24b.
- the first link 11a is eccentrically at one end the locking disc 17a of the one device half 10a and with the the other end on the first lever arm 23b of the locking member 18b of the other Device half 10b attached.
- the second link 11 b with one end eccentrically on the locking disc 17b of the other device half 10b and with the other end on the first lever arm 23a of the locking member 18a of the one device half 10a attached.
- the second lever arm 24a or 24b of the locking member 18a or 18b is located at the end in the area of action of a blocking curve section 25a or 25b of the associated locking disk 17a or 17b.
- the Switching device 2a can be switched on.
- the switching shaft rotates when switched on of the switching device 2a clockwise and thus through the coupling the locking disk 17a also via the driver 20.
- This will the first connecting member 11a is acted upon in the direction of arrow F and causes the other switching device 2b to pivot Locking member 18b in a counterclockwise direction, causing its second lever arm 24b in the area of the locking curve section 25b of the associated locking disk 17b arrives.
- the other switching device 2b also turn on, then the intended turn on motion whose shift shaft is effectively blocked because the shift shaft of the switching device 2b is coupled to the locking disk 17b, which in turn is blocking Engages with the second lever arm 24b of the locking member 18b and is prevented from further clockwise rotation.
- the locking device 1 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 element 18a and 18b, which are operatively connected to the second lever arm 24a or 24b.
- the Auxiliary switches 32 take appropriate depending on the position of the locking members 24a and 24b Switching states that are not used as signaling and / or Command signals can be processed further.
- the locking member 18a or 18b is opposite to the direction F of its train application by the second Link 11b and 11a acted upon by a first spring element 26.
- the first spring element designed as a helical compression spring 26 is supported between one in the shell-like part 13 of the insulating material housing 12 trained support 28 and the first lever arm 23a or 23b of the locking member 18a or 18b.
- the effect of the first Spring element 26 is that in one device half 10a or 10b of the locking device 1 in the rest position shown Locking element 18a or 18b from the locking curve section 25a or 25b of the associated Locking disc 17a and 17b is pivoted and thus via the operative connection with the connecting member 11b or 11a of the blocking curve section 25b and 25a of the locking disc 17b and 17a in the other device half 11b or 11a safely from the second lever arm 24b or 24a of the associated locking member 18b or 18a is turned away.
- the spring elements 26 are designed with regard to their spring force so that they in the off position of the switching device 2a or 2b, the locking member 18a or 18b clockwise so that its second lever arm 24a and 24b actuated the auxiliary switch 32, the actuating plunger with an opposing spring force are applied.
- the lock washer 17a, 17b is acted upon by a second spring element 27. That as helical compression spring formed second spring element 27 is on a spring plunger 29 mounted between one in the shell-like part 13 trained plunger guide 30 and a peripheral pin 31 of Locking washer 17a and 17b supported.
- the spring plunger 29 is arranged that when switching the switching device 2a or 2b on or off Pin 31 the imaginary connecting line between the axis of rotation 19 of the Locking disc 17a or 18a and the plunger guide 31 and thus passes through a point of maximum force application.
- the lock washer 17a and 17b thus forms a dead center system with the second spring element 27, which has the purpose of the switching shaft of the associated switching device 2a or 2b when switching on negative effects of the locking device 1 to relieve.
