Embodiment Construction

[0066] All figures are purely diagrammatic and show the invention with its main components. In this case, the same reference numerals correspond to identical components or functionally comparable components.

[0067] Locking device 1 according to the invention—cf. Figure 1 to Figure 6 — is intended to be compatible with manual operability — see Figures 7 to 10- The circuit breaker or power switch 2 is designed to work together. Manual operation of the circuit breaker 2 , that is to say switching on or off or reconnecting of the contact system of the circuit breaker 2 , takes place via an operating switch designed as a toggle lever 3 . A locking mechanism (not shown) provided in the housing of the circuit breaker 2 is used to operate a switch spindle (not shown) in rotation by means of the tilting lever 3 and to open the switch in the event of a short circuit or an overcurrent contacts (not shown). In this case, the force required for switching on or off is transmitted by...

Abstract

A locking apparatus is disclosed for an electromechanical switching device having a manual actuation option. Furthermore, such a switching device is also disclosed. A robust, mechanically simple locking apparatus is provided which can be operated without a tool, as well as a correspondingly embodied switching device. The locking apparatus of at least one embodiment includes a combination of few interacting construction elements attuned to one another in terms of structure and function. In this apparatus, a locking element assumes a double function, by, on the one hand, securing the connection of the locking apparatus with the switching device and on the other hand preventing a change in position of the actuation element of the switching device.

Description

technical field [0001] The invention relates to a locking device for an electromechanical switching device with manual actuation possibility. Furthermore, the invention relates to such a switching device. Background technique [0002] Electromechanical switching devices with manual operation are known from the prior art. Said manual operation is preferably done by means of a rotary switch or a toggle lever. [0003] In order to prevent unintentional or unauthorized actuation of the switching device, it is known to lock the actuating part in the safety position ("off" position) by means of a locking device which can be fastened to the switching device. Such locking can usually be additionally secured by means of a lock, for example a bow pin (Bügelschlo®), or the like. [0004] The latching devices disclosed in the prior art are generally of limited functionality, or are expensive and cumbersome to operate. Mounting on the switchgear is therefore generally only possible w...
