The invention relates to a protection system for an electrical machine, wherein the electrical machine has a housing (11) which delimits an internal space (12) in the electrical machine from an external space (13) which surrounds the electrical machine. The invention further relates to an electrical machine which has a housing (11), which delimits an internal space (12) in the electrical machine from an external space (13) which surrounds the electrical machine, and a protection system of this kind. In order to provide a protection system and, respectively, an electrical machine with improved protection of the electrical machine, in particular with improved explosion protection, it is proposed that the protection system has a first connecting line (3), by means of which the internal space (12) can be connected to the external space (13), a valve (4) and a filter (5) which is impermeable to dust (14), wherein the valve (4) and the first connecting line (3) are designed in such a way that the first connecting line (3) is impassable when the valve (4) is closed, wherein the valve (4) and the first connecting line (3) are designed in such a way that a first gaseous medium can enter the internal space (12) from the external space (13) when the valve (4) is open, wherein the filter (5) is arranged in such a way that the first gaseous medium which enters the internal space (12) from the external space (13) through the first connecting line (3) can be filtered. |
