Abstract

The invention relates to an electric leakage mutual inductor for high-power copper bar measurement, which comprises a mutual inductor shell (1), a circle of metal shielding layer (11) is connected inthe mutual inductor shell (1), a mutual inductor winding (4) is connected in the mutual inductor shell (1) positioned outside the metal shielding layer (11), and a group of through holes (12) are formed in the mutual inductor shell (1) positioned in the metal shielding layer (11); the mutual inductor winding (4) comprises an annular magnetic core (4a) and a set of secondary coils (4b) evenly woundon the annular magnetic core (4a), a set of parallel copper columns (2) are correspondingly connected into the through holes (12), threads (2a) are arranged at the two ends of each copper column (2),and the two ends of each copper column (2) are each connected with a copper sleeve (3). The mutual inductor has the advantages that the magnetic balance characteristic and the detection precision ofthe leakage transformer are improved, the installation of a high-power copper bar scene is facilitated, the magnetic field distribution is more uniform, and the normal use of the funnel transformer ismaintained.
