Beschreibung
Zusammenfassung:	The invention relates to a monitoring device for a converter of a rail vehicle, wherein the converter comprises at least a number of power capacitors and a number of power semiconductor switches which are arranged in a common, at least substantially closed housing. The monitoring device characteristically comprises an evaluation device and at least one gas sensor connected to the evaluation device for signal-transmitting purposes, wherein the evaluation device is configured to interrupt a supply of energy to the number of power capacitors of the converter depending on a concentration, detected by means of the at least one gas sensor, of at least one combustible gaseous compound in the housing of the converter.
