Abstract

The invention provides a new transposition wire rigidity test device with simple structure and convenient and rapid use. The device can be used to solve the problem that the traditional transposition wire rigidity test device can not detect the elasticity recovery amount of an unloaded transposition wire per se, can increase the accuracy of test results and can ensure that tests on a transposition wire with a slim cross section can be smoothly completed. The device comprises a base, the base is laterally provided with one pair of L-shaped sliding blocks, and the L-shaped sliding blocks are arranged oppositely and fixed on the base through bolts; the side face of the base is provide with a scale, and the L-shaped sliding blocks can move to a specified distance according to the scale label. The device is characterized in that the center of the base is provided with a reciprocating displacement transducer, and the reciprocating displacement transducer is provided with a pressure gage through signal connection.

Description

Technical field [0001] The invention relates to the field of transposition wire test equipment, in particular to a novel transposition wire rigidity test device. Background technique [0002] In the transformer industry, in order to simulate the strength that the transposed conductor can withstand in the operation of the transformer, it is necessary to conduct a rigidity test on the transposed conductor. The current rigidity test device for the transposed conductor mainly detects that the straight transposed conductor baked as required The displacement under load and the maximum load that the transposed wire can follow. With the development of the transformer industry, it is necessary to detect the degree of elastic recovery of the transposed wire itself after unloading. The current rigidity test device for transposed wire is mostly suitable for transposition Destructive load test of the wire, its structure is like figure 1 As shown, a pair of sliders 14 are installed oppositely ...
