Electrical switching system for a three-phase network

The invention relates to an electrical installation (1) for a three-phase alternating current network, comprising, for each phase (U, V, W) of the alternating current network, a transformer (20U, 20V, 20W) having a primary side (30U, 30V, 30W) and a second side; for each transformer (20U...W), a sep...

More Information
Summary:The invention relates to an electrical installation (1) for a three-phase alternating current network, comprising, for each phase (U, V, W) of the alternating current network, a transformer (20U, 20V, 20W) having a primary side (30U, 30V, 30W) and a second side; for each transformer (20U...W), a separate transformer housing (60U, 60V, 60W); a switching assembly (100), which is connected to the transformers (20U...W), wherein in each phase, the primary side (30U...W) and/or secondary side has a main winding (21, 22, 23) and a control winding (31, 32, 33); the switching assembly (100) is designed in such a way that the switching assembly can connect each control winding (31, 32, 33) to each of the main windings (21, 22, 23); the switching assembly (100) is arranged in one of the transformer housings (60U...W) or in a separate switching housing (70).
