Definitions
- the invention relates to a modular switching device according to the preamble of claim 1.
- the operational capability of a (low-voltage) switching device is generally limited by the so-called electrical life.
- the end of the electrical life is reached when the contact material is completely consumed at the switching pieces of the switching device or when solid and movable contact pieces weld together.
- the consumption of contact material depends on a contactor after the switched load.
- the electrical life is mainly determined by the level of the short-circuit current cut off.
- a switching device is known from DE 689 06 238 T2.
- the local switching device comprises a switching chamber with a multi-pole circuit breaker for switching the power lines of a main flow path.
- the known switching device further comprises two actuation modules, which are removable for exchanging these modules, in particular in switching-technically mounted switching chamber, and which contain electro-mechanical components for direct actuation or indirect actuation of the circuit breaker.
- protective devices are associated with the indirect actuation module which, upon detection of an anomaly of the current flowing in the main flow path, actuate a switch lock, which in turn acts to interrupt the main flow path to the circuit breaker.
- the protective devices are electrically contacted via contact pins and corresponding contact sleeves with the power lines of the main flow path, so that the main flow path from the switching chamber is guided into at least one of the actuation modules.
- the invention has for its object to provide a switching device that can be used in a simple manner at least partially beyond the usual electrical life out.
- the switching device is modular and includes a switching chamber containing all the components of a switching unit associated with this main circuit in addition to a switching unit.
- the switching device further comprises a base module which comprises a mechanically and / or electrically (and thus optionally also electro-mechanically or electronically) controllable triggering mechanism for actuating the switching unit.
- the switching chamber and the base module are in this case (non-destructive) removably attached to each other, so that after the end of the electrical life of the consumed Switching chamber can be replaced with little effort against a new switching chamber, and thus the remaining base module over the period of electrical life is also reusable.
- the invention again takes up the concept of a modular switching device.
- the use of the modular construction takes place here before a different background than in the prior art, in particular for solving a task that played no role in the design of the prior art modular switching devices.
- the use of the modular design to achieve a variable functionality by combining the switching chamber with different types of functional modules.
- the interchangeability of the switching chamber achieved according to the invention is achieved in particular by the combination of two features that synergize only before the background according to the application, namely on the one hand, the removable attachment of the switching chamber to the base unit, which allows an exchange of the former, and on the other hand, the exclusive arrangement of Main flow path within the switching chamber without which an exchange of the latter in terms of the usability of the switching device would ultimately be ineffective.
- the base module comprises an electro-mechanical drive for the electrical control of the switching unit.
- This drive is realized in a conventional manner in particular by an electromagnet which acts mechanically on the switching unit via a plunger.
- the drive is on the one hand directly actuated by electrical control from the outside, so that by means of the drive, the switching device can be electrically switched.

- the release mechanism is in this case designed such that all individual switches are operated simultaneously during normal operation.
- the switching chamber and the base module are in particular screwed together or releasably locked together.
- the fastening means provided for this purpose act in the joining direction, so that only a unidirectional plugging movement is required for connecting and disconnecting the switching chamber and the base module, including their mutual fastening.
- the fastening means eg, the screws or latching hooks
- the connection between the base module and the switching chamber can therefore be solved only when dismantled switching device.

- the switching mechanism 21 further comprises an electromagnetic drive 26, which acts on the switching unit 12 via a deflecting member 27 and a plunger 28.
- the drive 26 can be controlled via an electrical control line 29 from the outside.
- the drive 26 is designed such that it releases the switching unit 12 as long as a non-zero control voltage U is supplied via the control line 29, and that it actuates the switching unit 12 (and thus interrupts the main flow path 6) as soon as the via the control line 29 supplied control voltage U collapses.
