Method and device for determining transformer core column lamination scheme

Abstract

The invention discloses a method and a device for determining a transformer core column lamination scheme. The method includes: determining a core column target diameter; determining lamination parameters of the first-stage lamination according to the target diameter of the core column; determining lamination parameters of other levels of laminations step by step according to a sequence from nearto far away from the first lamination, determining the combination of the lamination parameters of each stage of lamination as a core column lamination scheme and storing the core column lamination scheme; circularly executing the process to determine and store a plurality of core column lamination schemes; evaluating a standard according to a preset scheme; determining an optimal core column lamination scheme from the determined core column lamination schemes; according to the method, manpower consumed by manually modulating the core column lamination scheme can be reduced, the modulation efficiency of the core column lamination scheme is improved, the modulation cost is reduced, the probability that the operation performance of the transformer cannot reach the standard due to subjectiveexperience of manual modulation can be reduced, and the design of the core column lamination scheme is standardized.

Description

Technical field [0001] The present invention relates to the technical field of transformers, and in particular to a method and device for determining a transformer core column lamination scheme. Background technique [0002] The three-phase three-column iron core is the supporting frame of the transformer body. It is composed of an upper iron yoke, a lower iron yoke and three core columns. Each core column can be composed of the first-level stack and the two It is composed of stacks of other levels (such as second-level stacks and third-level stacks) distributed in steps on the side, and each stack is composed of multiple laminates. Among them, the larger the stack distance from the first-level stack, the greater the sequence number corresponding to the stack. The larger the number of the series, the smaller the width corresponding to the laminate. For example, the width of the second-level laminate is smaller than the first-level laminate, and the width of the third-level lamin...

However, the existing core column stacking scheme uses manual modulation, which will be affected by subjective experience when determining the above parameters, and the modulation efficiency is low and the labor cost is high.
