CAPACITOR COMPRISING A PROTECTIVE DEVICE

摘要

The invention relates to a capacitor (1) comprising a protective device (2). In order to identify a fault status in a capacitor (1) in a simple manner, it is proposed that the capacitor (1) have a housing (3) sealed in such a way that the volume of the housing (3) changes in the case of a fault, wherein the change in volume of the housing (3) can be detected by the protective device (2). The invention further relates to a power converter comprising such a capacitor (1) and a method for identifying a case of a fault in such a capacitor (1), wherein the protective device (2) detects a change in volume of the housing (3).
