The invention discloses a non-destructive detection testing clamp for a dry type distribution transformer winding material. The non-destructive detection testing clamp comprises a first testing clamping plate, a second testing clamping plate, and further comprises a first clamping block, a second clamping block and a pair of torsional springs, wherein the first testing clamping plate and the second testing clamping plate are fixedly connected through male-female pivots; the first clamping block is clamped in the first testing clamping plate through a fan-shaped slot; the second clamping blockis clamped on the second testing clamping plate through the other fan-shaped slot; the pair of the torsional springs penetrate through the male-female pivots; end corners of the torsional springs areclamped in an inner groove formed by the first testing clamping plate and the second testing clamping plate; preserved copper wire holes and preserved nickel-copper wire holes are formed in both the first clamping block and the second clamping block. The non-destructive detection testing clamp has the beneficial effects that the problem of acquiring thermoelectric force and temperatures of a dry type distribution transformer winding contact is effectively solved, the thermoelectric force can be acquired by using two identical copper wires of two pairs of thermocouples, thermoelectric force acquisition accuracy is ensured, the quantity of wires on the clamps is reduced, and accurate and convenient testing can be carried out.
