Transposed conductor self-adhesion test clamping device

Abstract

The invention discloses a transposed conductor self-adhesion test clamping device. The transposed conductor self-adhesion test clamping device comprises a bottom plate (1), a side plate (2), a top plate (3) and limiting columns (4). The side plate (2) is fixedly arranged at the rear end of the bottom plate (1), the top plate (3) is arranged on the side plate (2) in an up-down sliding manner and ispositioned above the bottom plate (1), the right end of the top plate (3) is provided with a plurality of through grooves (32) with openings in the front ends and arranged front and back, the throughgrooves (32) are arranged left and right, the limiting columns (4) correspond to the through grooves (32), the lower ends of the limiting columns (4) are arranged on the bottom plate (1) in a front-back sliding mode, and the upper portions of the limiting columns (4) penetrate the through grooves (32) and are locked and fixed through locking devices. The transposed conductor self-adhesion test clamping device is simple in structure, achieves superposition and fixation of transposed conductors with different sizes and numbers, and enables the self-adhesion test effect to be better.

Description

technical field [0001] The invention relates to the field of wire testing, in particular to a clamping device for transposition wire self-adhesive testing. Background technique [0002] The transposition wire can greatly reduce the load loss, reduce the temperature rise of winding hot spots, improve the mechanical strength of the winding, make the structure more compact, and the coil processing is easier, so it is widely used in the design and manufacture of large-scale power transformer windings. [0003] The transposition wire is composed of a certain number of enamelled copper flat wires into two rows in which the wide surfaces are in contact with each other, and the transposition of the same direction is made on the top and bottom of the two rows of enameled wires along the narrow surface as required, and an electrical insulating paper tape is used to It is made of multiple layers of continuous and tightly wrapped wires; after the production of the transposed wires, a se...

[0003] The transposition wire is composed of a certain number of enamelled copper flat wires into two rows in which the wide surfaces are in contact with each other, and the transposition of the same direction is made on the top and bottom of the two rows of enameled wires along the narrow surface as required, and an electrical insulating paper tape is used to It is made of multiple layers of continuous and tightly wrapped wires; after the production of the transposed wires, a self-adhesive test is required for the transposed wires, that is, the transposed wires are pressed tightly so that each composed of wires fits closely, and placed in a high temperature In the experimental equipment, the self-adhesive quality of the transposed conductor is judged by detecting the change of the self-adhesive paint of the conductor at high temperature. The existing test clamping device clamps and fixes the transposed conductor. And the number of transposed wires are uniformly clamped and fixed. When a small number of transposed wires are tested, the overall time under high temperature test is too long, and the test efficiency is low.
