Abstract
The invention relates to a capacitor module for a converter. The capacitor module contains a capacitor which can be fastened to a base frame or to a cooling body by means of lateral, mechanical holding devices. In addition, the capacitor comprises at least one additional mechanical holding device for fastening at least one electronic terminal of the converter and of at least one measuring sensor, especially of a current transformer and/or of a voltage transformer. The inventive capacitor module makes it possible to realize a construction of a converter which is compact and has a reduced weight.
