Definitions
- the invention relates to an overvoltage protection device which has at least one overvoltage protection unit with at least one contact lug and a mechanical severing device activated in the event of thermal overload, wherein the mechanical severing device comprises a connection element which can be moved from a closed slide into a current-interrupting or potential-separating position by means of a slide biased by a spring force is, according to the preamble of claim 1.
- Overvoltage protection devices with thermal cut-off device have been part of the known state of the art for many years.
- the object of a separating device is, in case of excessive heating of the overvoltage protection unit, e.g. a varistor to safely disconnect this from the grid before a destruction of the Abieiters occurs.
- the utility model DE 295 19 313 Ul shows an overvoltage protection device with a separation device on a thermal basis, wherein via a
- the separation device is positioned separately from the actual varistor.
- the surge current carrying capacity of such a separation device is under current aspects too low and it is the local solder joint exposed to a constant spring biasing force.

- the previously known solution has a high surge current carrying capacity, wherein the contact pressure for the discharge process is produced by the surge current itself.
- the separating device according to DE 10 2007 042 991 B4 is realized in such a way that the supply to the voltage-limiting overvoltage protection units, in particular varistors, is formed by two conductor sections through which surge current flows in the same direction, which run parallel in the end region and enter a common connection point, which is secured by a solder. Due to the parallel current flow and the associated force effects in the
- Shifting current paths and thus interrupting the circuit can be performed with less spring force, so that a low continuous load of Lotstelle is the result. Since the slide moves directly into the Lotstelle in the separation case, negative effects are prevented in the separation process and achieved a safe, stress-free separation.
- a disadvantage of the solution according to DE 10 2007 042 991 B4 is the fact that the slide is functionally coupled with the optical signaling of the slide position and thus an indication of the functional properties of the separating device. For this reason, therefore, the slider must be constructively designed so that it has a flat as possible, color differentiated display surface to make the respective functional state of the corresponding surge protection device. Furthermore, the direction of movement of the slider for the purpose of separating the preferably used varistors in case of overload is predetermined, so that the position of a viewing window for detecting the movement state of the slider is determined constructively, which is e.g. represents a disadvantage in reducing the size of corresponding overvoltage protection devices.
