At present, the existing locomotive transformer core is cut and stacked by grain-oriented cold-rolled silicon steel sheets. The high and low voltage windings are separately wound and poured separately. Therefore, the finished transformer has a simple process structure and high no-load loss, which limits the locomotive transformer. range of use, reducing the efficiency of the transformer

Embodiment Construction
[0011] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0012] Such as figure 1 , figure 2 , image 3 As shown, an epoxy resin locomotive transformer 1 includes a three-phase alloy iron core 11, a high and low voltage combined coil winding 12, and a connector 13. After forming, the connecting piece 13 clamps the left and right side columns, and tightens the upper and lower iron core steel splints 14 so that the transformer 1 forms a firm whole. The three-phase alloy iron core 11 is made of 0.025mm alloy steel strip, the core column is bound with H-grade insulating tape, and the surface is coated with solvent-free resin.
[0013] The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above. Those skilled in the ind...

The invention provides an epoxy resin locomotive transformer, relates to manufacturing technology of a transformer used in a locomotive and belongs to the technical field of electricians. The epoxy resin locomotive transformer comprises a three-phase alloy iron core, a high voltage and low voltage combined coil winding, and a connecting piece, and is characterized in that: the high voltage and low voltage combined coil winding is integrally poured and formed by epoxy resin; a left edge column and a right edge column are tightly clamped by the connecting piece, and an upper iron core steel clamping plate and a lower iron core steel clamping plate are tensioned to make the transformer form a firm whole; the three-phase alloy iron core adopts an alloy steel band which is 0.025 millimeters thick; the core column is tied and bundled by an H-level insulation band; and the surface is coated by solvent-free resin. The epoxy resin locomotive transformer has the advantages that: the high voltage and low voltage combined coil winding in the transformer is integrally poured and formed by epoxy resin, so the inner field intensity of the winding is improved, the impact resistance is enhanced, and the mechanical strength is increased; moreover, the epoxy resin locomotive transformer is simple and rational in structure, good in electric performance, small in volume, light in weight and convenient to life and install.
Description
technical field [0001] The invention relates to the manufacturing technology of a transformer used on locomotives, belongs to the field of electrical technology, and in particular relates to an epoxy resin locomotive transformer. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. In electrical equipment and wireless circuits, it is often used for voltage boosting, matching impedance and safety isolation. At present, the existing locomotive transformer core is cut and stacked by grain-oriented cold-rolled silicon steel sheets. The high and low voltage windings are separately wound and poured separately. Therefore, the finished transformer has a simple process structure and high no-load loss, which limits the locomotive transformer. The scope of use reduces the working efficiency of the transformer. Contents of the invention [0003] The technical problem solved by the present invention is to prov...
