Wandleranordnung am Feldanschluß von gekapselten Mittelspannungs-Schaltanlagen

摘要

The invention concerns a transformer assembly intended for the field terminal of encapsulated medium-voltage switchgear with a circuit-breaker housing which is connected to a bus-bar housing by means of a flange and a cable lead-through and connected to a cable-terminal housing by means of a polar plate via another lead-through. The gastight cable-terminal housing (KAG) includes an upper half (GTO) whose cross section is reduced in size relative to lower half (GTU) and which is closed by a first mounting plate (TP1) projecting out beyond the cross section of the upper half (GTO) of the housing and designed to carry at least one toroidal-core transformer (RKW). Transformer assemblies of this kind are suitable for use in gas-insulated heavy-duty switchgear.
