Abstract
A power line filter for 3-phase systems has a metallic filter housing which is subdivided by partitions into radio frequency sealed chambers. The chambers contain a power supply part, a first combination of feed through capacitors, attenuation elements, a second combination of feed through capacitors and a load connecting part. Phase conductors and a neutral conductor are connected through a respective annular feed through capacitor in the partition region from the power supply part to the first combination of feed through capacitors, and a similar connection is made between the second combination of feed through capacitors to the load connecting part. Phase feed through capacitors are provided per combination of feed through capacitors, and are accomodated in a feed through capacitor housing seated impact resistance in the filter housing. The annular feed through capacitor is arranged in the partition region and has one coating rigidly connected to the feed through capacitor housing and has its other coating connected to a metallic corregated hose which is conducted through this annular feed through capacitor. The metallic corregated hose carries a ring at its end facing the partition and is connected in a radio frequency sealed fashion to a sealing ring inserted in the partition.
