Description
Technical field
The present invention relates to transformer, more particularly, to a kind of single-phase isometric sawing sheet method of seven grades of volume iron core four section.
Background technology
The characteristics of Single-phase roll iron-core transformer is maximum is that, which employs coiled core, iron core uses high-quality cold rolled silicon steel
Piece, electromagnetic performance is good, without seam, and the fastening effect of iron core winding and iron core and winding is good, can be big compared to laminated transformer
Width reduces open circuit loss and no-load current, it is possible to decrease noise 7-10dB.
The core section of the single-phase volume iron core of most of producers uses seven sections of material strips, seven grades of cross section structures, the length of every grade of material strip
Degree can change because location is different, and most long material strip length is 4-5 times of most short material strip length, and every straight material strip is pressed
Oblique material strip sawing sheet is carried out shown in Fig. 2, as band needed for single-phase volume coiling iron core.This mode brings many tired to slitting discharge
Difficulty, can produce many clouts and stock in actual production, add many material costs or even cause portion of material to waste.
The content of the invention
It is an object of the invention to provide one kind using straight as the fourth stage by four sections of isometric straight material strips, the 4th section of straight material strip
Material strip is directly used in winding unshakable in one's determination, the straight material strip of its excess-three section and is cut into six grades of oblique material strips, makes core section be seven grades of trapezoid cross sections
Seven grades of isometric sawing sheet methods of the single-phase volume iron core four section of single-phase rewinding material.
