Anti-interference transformer

The anti-interference transformer comprises a shielding box and a transformer body, the transformer body is arranged in the shielding box, the shielding box comprises a box body, a first shielding layer is plated on the inner wall of the box body, a plurality of heat dissipation holes are formed in the box body, and the first shielding layer is arranged on the inner wall of the box body. The transformer body comprises a magnetic core, a primary coil and a secondary coil, a second shielding layer is plated on the outer layer of the magnetic core, the primary coil is wound on the second shielding layer, a third shielding layer is arranged on the outer layer of the primary coil, and the secondary coil is wound on the third shielding layer. The number of turns of the primary coil is the same as that of turns of the secondary coil. A first shielding layer is plated on the shielding box, so that external electromagnetic interference on the transformer body can be effectively prevented; and corresponding shielding l
