A dc transformer/reactor having insulated and screened winding conductors

摘要

A DC transformer/reactor includes a magnetic circuit with a magnetic core and at least one winding that is directly connected via a converter circuit to a DC network. The winding includes a conductor 2 that is insulated with two semiconducting layers 3, 5, each layer constituting an equipotential surface, and the semiconducting layers being separated by a solid insulation layer 4.
