The invention relates to a transformer current output bushing magneto-resistance plate. The magneto-resistance plate is fixedly connected onto a transformer box cover. A through hole for installing a current bushing is formed in the magneto-resistance plate. The transformer current output bushing magneto-resistance plate has the advantages that the structure is simple, the production cost is low, the service life of a transformer is prolonged, the magneto-resistance material is not excessively used, the waste is avoided and the magneto-resistance effect is achieved; when current is too heavy, since the magneto-resistance plate made of the magneto-resistance material is adopted on the installation surface of the transformer which is directly influenced by the produced electromagnetic diffraction, an eddy current effect which is caused by flux leakage is not formed and the eddy current loss is prevented from being caused.
