Two chamber expansion vessel for liquid cooled tapped transformers and choke coils

摘要

The two chambers are separated from each other in a fluid-tight manner. The main chamber (4) and the secondary chamber (5) are formed and arranged in the base vessel (2) such that the tubes coming out of the chambers (4,5) are fed into the vessel (2). The sequence of the tubes on exiting without impeding the oil indicator for the individual chambers (4,5) corresponds to the tank tube on both sides of the transformer tank (17). The oil indicators for the two chambers (4,5) are arranged on the same side of the vessel (2) and are directed the same way. Each chamber (4,5) has an individual cover (7,19) releasably connected to a corresponding frame of the vessel (2) with an intermediate seal. The transverse contact points are formed and arranged for a fastening at both sides of the transformer tank (17).
