ABSTRACT:
A holding device for encased capacitors used for electric drive engineering. The inventive holding device comprises integrateable and separable lower and top holding parts. Axially protruded retaining clamps are arranged on the top holding part around each encased capacitor. The lower holding part comprises an opening for the respective capacitor and each opening is surrounded with a sealing lip. The retaining clamps are pressed against the capacitors by the internal surface of the lower holding part. Sections protruded from the respective openings of the lower holding part are embodied in the form of the capacitor sections freely extending directly to a cold air flow of a device. The sealing lip is sealingly placed on the external wall of each encased capacitor in such a way that the penetration of solid or liquid materials inside the lower holding part is prohibited, thereby preventing a high IP protection degree.
