Stacked triangular core structure

Abstract

A stack-mountedangle ironcardiac structure, a power distribution equipment. Performance location to set up three ground - 1.30-Core stack-loaded, its approximate circular cross-sectional area through upper and lower approximation of the three semi-circular cross-sectional area of iron tablets conjugate inserted three core columns connected together to form a three-dimensional closed triangle magnetic circuit; the structure of the transformer core, magnetic circuit completely symmetrical three-phase, short magnetic circuit small size, less supplies, silicon steel material utilization as high as 99%, No Load Current and Loss greatly decreased, is a highly efficient the transformer core energy saving and environmental protection structure and add new equipment without using conventional plane loaded with Core stack processing equipment can be achieved, and to address the triangular wound core equipment investment, such as coil winding inconvenient inadequate.

Description

Technical field [0001] The invention relates to a stacked triangular iron core structure, which belongs to the technical field of power transmission and distribution equipment and is suitable for small and medium-sized transformers. It is composed of three-dimensional triangular stacked iron core columns, and the three core columns are connected by upper and lower iron yoke inserts to form a closed three-dimensional triangular magnetic circuit. Background technique [0002] The iron core structure of the traditional three-phase transformer is mostly made of stacked or rolled silicon steel sheets arranged in a plane. The iron core with a stacked structure of silicon steel sheets arranged in a plane has some shortcomings: the utilization rate of the silicon steel sheets is low, the consumables are large, and the volume is large; The rolled iron core that has been popular for several years has the advantages of low no-load loss and low noise, but there are still strict requirem...

Problems solved by technology

[0004] A stacked triangular iron core structure according to the present invention is manifested as a three-dimensional triangular stacked iron core column with three positions, and its cross-sectional area is approximately circular. The yoke insert connects the three iron core columns to form a closed three-dimensional triangular magnetic circuit; the three-phase magnetic circuit of the transformer core with this structure is completely symmetrical, the magnetic circuit is short, the volume is small, the consumables are less, and the utilization rate of the silicon steel sheet material is as high as 99%. , the no-load current and no-load loss are greatly reduced, and it is a high-efficiency, energy-saving and environmentally-friendly transformer core structure; and it does not need to add new equipment, it can be realized by using the processing equipment of conventional planar stacked cores, and solves the problem of triangular wound cores Large equipment investment, inconvenient coil winding, etc.
