MEASURING ARRANGEMENT FOR DETECTING A MAGNETIC UNIDIRECTIONAL FLUX IN THE CORE OF A TRANSFORMER

Measuring arrangement for detecting a magnetic unidirectional flux in the core of a transformer, wherein a sensor (1), formed from a ferromagnetic sensor core (2) which is wrapped around by a sensor coil (3), is arranged in a section of a core limb (6) in a cooling channel (5), said section being pr...

Zusammenfassung:Measuring arrangement for detecting a magnetic unidirectional flux in the core of a transformer, wherein a sensor (1), formed from a ferromagnetic sensor core (2) which is wrapped around by a sensor coil (3), is arranged in a section of a core limb (6) in a cooling channel (5), said section being predefined by the winding width (15), or in an annular space (21), formed from an outer peripheral surface (4) of the core limb (6) and an inner peripheral surface (22) of an associated transformer winding, in such a manner that a magnetic partial flux (7) is diverted by the core limb (6) and guided over at least one non-ferromagnetic gap (10).
