Transformer core is with big current lead magnetic leakage shield assembly

The utility model relates to a transformer core is with big current lead magnetic leakage shield assembly belongs to the transformer and makes technical field. Technical scheme is: the department is equipped with copper product shield ring (3) at transformer core final stage lamination, sets up heat dissipation oil duct (2) unshakable in one's determination between copper product shield ring (3) and time final stage lamination unshakable in one's determination, and copper product shield ring outside sets up arm -tie (1), sets up hot oil duct unshakable in one's determination two (4) between copper product shield ring and the arm -tie unshakable in one's determination, set up the insulating pad between arm -tie and web unshakable in one's determination, make between arm -tie and the web unshakable in one's determination insulatingly to prevent the circulation that big current lead caused and arouse overheated. The utility model discloses the magnetic leakage is shielded in the circulation effect of diamagnetic
