- the invention relates to electrical devices with electrical modules, which are each equipped with at least one electrical component accommodated in a module housing, electrical modules as such, and a method for producing modules for electrical devices.
- Electrical modules are used for example in electrical To ⁇ judges, in particular Multilevelumrichtern in which a plurality of electrical modules of the type described is placed very close to each other.
- the modules are often electrically connected in series with such converters to form module series circuits.
- the publication WO 2012/156261 A2 describes an exemplary embodiment of a multilevel converter in which electrical modules, as described below, can be used.
- the electrical modules described are loaded with very large electrical currents, so that in the event of a failure ei ⁇ ner component or in an error due to the umge ⁇ set electrical power an explosive destruction ⁇ tion located in the module housing electrical component or components can be made; If explosive gas (eg metallic / carbonaceous dust, splinters, etc.) deviates from the module housing, adjacent electrical modules, which previously worked in an electrically faultless manner, can be affected or destroyed by the explosion gas (for example indirectly by reducing the insulating capacity of the air due to the impurities), so that a chain reaction may occur which destroys a plurality of adjacent electrical modules. In the case of the above described This can have dramatic consequences, especially in the high-voltage sector.

- an energy reduction of the explosion gas is achieved by stretching and increasing the volume in an advantageous manner.
- the adhesive layer in the expanded volume region can bind particles of the explosion gas.
- the film acrylate at least one film ⁇ layer of polyurethane (PUR) with a thickness between 0.1 and 1 mm and an adhesive layer of acrylate or rubber or at least or rubber-based or -based adhesive.

- the film may be, for example, the film of the type PU 8592 E from 3M® , polyurethane adhesive tape of the type 8560, 8561 and 8562 from 3M or a security film of the type
