Abstract

The invention is applicable to the technical field of transformers, and provides a transformer coil circulation loss calculation method and device. The calculation method comprises the steps: establishing a two-dimensional axisymmetric field, and in the two-dimensional axisymmetric field, establishing a wire-level model of a coil needing to calculate circulation loss; for the coil which does not need to calculate the circulation loss, establishing a coil-level model of the coil; connecting the wire-level models and the coil-level models to generate a transformer model; performing two-dimensional time-harmonic field simulation on the transformer model, extracting the current of the coil of which the circulation loss needs to be calculated from the simulation result, and calculating the circulation loss of the corresponding coil based on the current. According to the method, the relative positions and transposition conditions of the parallel wires in the coil can be accurately reflected,and the calculated circulation loss of the transformer coil is more objective and accurate.

Description

technical field [0001] The invention belongs to the technical field of transformers, in particular to a calculation method and device for transformer coil circulation loss. Background technique [0002] The transformer coil is the core component of the transformer. When the transformer is working, a current passes through the transformer coil. When the magnetic field generated by this current passes through the parallel wires of the transformer coil, a current will be induced. The loss caused by this current is the circulation loss. The circulating current loss should be accurately calculated and strictly controlled, otherwise it may cause the transformer load loss to exceed the standard, and even cause the hot spot temperature of the transformer coil to be too high and affect the safe operation of the transformer. [0003] The existing technology is to simulate and calculate the circulating current loss by establishing a coil-level model of the transformer coil. However, th...
