Flow path's partial alternating currents symmetrizing arrangement for e.g. circuit breaker, has secondary windings assigned to flow paths, where half of windings are oriented opposite to another half of windings with respect to paths

摘要

The arrangement has electromagnetic current transformers (U11, U12, U21, U22, U31, U32) assigned to outer flow paths (L11, L21, L22, L32) and middle flow paths (L12, L31) of same construction at a primary side. The paths are arranged in parallel and at left and right sides of electric switching devices (1,2). Secondary windings of the transformers are assigned to the flow paths. Half of the secondary windings is oriented opposite to another half of the secondary windings with respect to the flow paths in terms of electromagnetic conditions.
