Embodiment

[0048] see Figure 1-10 , a method for arranging annular laminated iron cores, is characterized in that, comprising the following steps:

[0049] a. The upper magnetic pole arrangement method:

[0050] a1. Process the silicon steel sheets into shapes with the same width and different lengths, and then arrange the silicon steel sheets of different lengths according to the length by gluing to form the upper magnetic pole a block 1, and process a total of 83 upper magnetic pole a block 1;

[0051] a2. Process the silicon steel sheets into shapes with the same width and different lengths, and then arrange the silicon steel sheets of different lengths according to the length by gluing to form the upper magnetic pole b-block 2, and process two upper magnetic pole b-blocks 2 in total;

[0052] a3. Arrange 83 parts of upper magnetic pole block a and 2 parts of upper magnetic pole block b 2 to form upper magnetic poles, wherein 2 parts of upper magnetic pole b blocks 2 are symmetrical...

Abstract

The invention discloses an arrangement method of an annular sheet-shaped laminated iron core, and belongs to the field of laminated iron cores. According to the scheme, silicon steel sheets with different lengths form an upper magnetic pole a block and an upper magnetic pole b block, then the upper magnetic pole a block and the upper magnetic pole b block are arranged to form an upper magnetic pole, and meanwhile, the silicon steel sheets with different lengths form a lower magnetic pole a block and a lower magnetic pole b block; the lower magnetic pole a and the lower magnetic pole b are arranged to form the lower magnetic pole, the 233 silicon steel sheets with different lengths are arranged to form the central iron core, the magnetic field intensity of the upper magnetic pole, the lower magnetic pole and the central iron core formed through the arrangement method is high, and the magnetic field distribution is more uniform.

Description

technical field [0001] The invention relates to the field of laminated iron cores, and more specifically, relates to an arrangement method of annular laminated iron cores. Background technique [0002] The laminated iron core is the main magnetic circuit part of the transformer. It is usually made of stacked hot-rolled or cold-rolled silicon steel sheets with high silicon content and coated with insulating paint on the surface. The iron core and the coil wound on it form a complete electromagnetic induction system. The transmission power of the power transformer depends on Depending on the material and cross-sectional area of ​​the core. [0003] Existing laminated iron cores have a cylindrical or rectangular columnar shape. The cylindrical laminated iron core is composed of circular silicon steel sheets arranged in sequence, and the rectangular columnar laminated iron core is composed of E-shaped silicon steel sheets arranged in a staggered order. However, the existing Th...
