Clamping piece structure of transformer

The utility model relates to a clamping piece structure of a transformer, which comprises an upper clamping piece and a lower clamping piece on the high-voltage side, as well as an upper clamping piece and a lower clamping piece on the low-voltage side, stretching screws sheathed with insulating paper pipes are arranged between the clamping pieces, the high-voltage upper clamping piece is connected with the low-voltage upper clamping piece by using a plate I, and the high-voltage lower clamping piece is connected with the low-voltage clamping piece by using a plate II. With the structure, the mechanical strength of a product can be improved, the operation stability of the product is more reliable and the noise is very small.
