Background
It is known in the electron accelerator production industry that reliable operation of an electron accelerator is a prerequisite for creating economic value for customers. A stable electric field is a prerequisite, and a power transformer with stable performance is a key core for ensuring the stability of the electric field. At present, most of iron cores used on power transformers of electronic accelerators are ferrite iron cores, the shape of the ferrite iron core is the same as that of a traditional transformer, the ferrite iron core is formed by butting two E-shaped iron cores, and the ferrite iron core is manufactured by adopting a sintering method. The power of the power transformer on the electron accelerator is large, and correspondingly, the volume of the E-shaped iron core is also large. Because the E-shaped iron core has a large volume, a large-power winding mold and a winding furnace body are required in the aspects of length, thickness and the like, the process is complex, and the sintered E-shaped iron core often has the phenomena of cracking, bulging, air holes and the like, so that abnormal fluctuation of voltage and current often occurs in application. Therefore, the integral high-power E-shaped iron core has the advantages of low qualification rate and high production cost.

One end of the middle transverse part is connected with the middle of the vertical part in an adhesive mode, and one end of the side transverse part is connected with the corresponding end of the vertical part in an adhesive mode. An inner shielding groove and an edge shielding groove are arranged between the middle transverse part and the adjacent side surfaces of the edge transverse parts of the two E-shaped cores, and the inner shielding groove and the edge shielding groove are both U-shaped. The transverse part and the vertical part of the inner shielding groove are respectively buckled on the middle transverse parts of the two E-shaped cores and the corresponding inner side surfaces of the vertical parts of the two E-shaped cores, and the transverse part and the vertical part of the side shielding groove are respectively buckled on the transverse parts of the same sides of the two E-shaped cores and the corresponding inner side surfaces of the vertical parts of the two E-shaped cores. Gaps are reserved between the vertical parts of the inner shielding groove and the side shielding groove on the same side.
The inner shielding groove and the side shielding groove are formed by bending red copper sheets.
The utility model discloses a further improvement scheme is, all there is the supporting layer on the perpendicular portion lateral surface of two E shape cores and on the corresponding limit horizontal portion lateral surface. The supporting layer is a stainless steel sheet which is connected with the outer side surfaces of the vertical parts and the corresponding outer side surfaces of the side transverse parts of the two E-shaped cores by means of adhesive.

One end of the middle transverse part is connected with the middle of the vertical part in an adhesive mode, and one end of the side transverse part is connected with the corresponding end of the vertical part in an adhesive mode. So that the E-shaped iron core is composed of a plurality of magnetic columns with smaller volumes. Because the E-shaped iron core is composed of a plurality of magnetic columns with smaller volumes, the single magnetic column can be sintered during sintering. Because the volume of a single magnetic column is small, a high-power winding mold and a winding furnace body are not needed, the process is simple, and the phenomena of cracking, bulging, air holes and the like and the condition that voltage and current are abnormally fluctuated when the magnetic pole is applied are avoided. Thereby greatly improving the product percent of pass and reducing the production cost.
