Combination of transformer and coil

摘要

Combination of a transformer and at least one coil to be incorporated in an electricity distribution network, comprising: at least one primary and one secondary transformer winding arranged on a transformer core placed in a housing, at least one coil winding placed in the same housing and placed on a coil yoke, wherein the at least one coil winding is permanently connected inside the housing to at least one transformer winding, wherein the at least one coil winding can be switched off by a switch not directly connected to the at least one transformer winding. This configuration provides the option of placing the switch outside the housing at a location in the circuit where the short-circuit capacity is limited.
