Abstract

The eddy current loss and shielding placement of traction transformer is one of the stable design links of the transformer. This paper takes a traction transformer as an object, and first analyzes and calculates the magnitude and distribution of the leakage magnetic field of the transformer. In order to reduce the eddy current loss of the tank, a magnetic shielding is arranged on the surface of the tank. To obtain the best shielding effect, the magnetic shielding structure of the front and rear sides of the tank is optimized from five aspects: width, height, thickness, distance between the shieldings and the distance between the shieldings and the tank. Based on the calculation results, the shielding characteristics of different shielding modes and structures of the tank are summarized.
