Large transformer clamp

The utility model provides a large transformer clamp which comprises an upper clamp body, a lower clamp body, an iron core, a first insulating tube and a second insulating tube, the iron core is clamped between the upper clamp body and the lower clamp body, the first insulating tube is arranged on the upper beam high-voltage side of the upper clamp body, and the second insulating tube is arranged on the lower beam high-voltage side of the lower clamp body. The second insulating tube is arranged on the high-voltage side, close to the side beam, of the lower clamping piece, and the problem that the load loss of the transformer is too large is solved by blocking the short circuit rings between the upper clamping piece and the lower clamping piece. 本申请提供一种大型变压器夹件，包括：上夹件，下夹件，铁芯，第一绝缘管以及第二绝缘管，所述铁芯夹持在所述上夹件与所述下夹件之间，所述第一绝缘管设置在所述上夹件的上梁高压侧，所述第二绝缘管设置在所述下夹件靠近侧梁的高压侧，通过阻断上下夹件之间的多个短路环，解决变压器负载损耗过大的问题。
