Interphase spacer and fittings tensile bending test platform

Abstract

The invention discloses an interphase spacer bar and a tension bending test platform for fittings, comprising a power drive system (1), an upper wire direct response system (2), a wire tension adjustment system (3), a transmission tension adjustment system (4) and a lower wire The indirect response system (5); the power drive system (1), the upper wire direct response system (2) and the transmission tension adjustment system (4) are sequentially connected end-to-end through the traction wire rope (7) to form a closed-loop structure, and the upper wire direct response system ( 2) Comprising the first sub-wire spacer (21) and the second sub-wire spacer (22), the power drive system (1) can make the traction wire rope (7) reciprocate in the axial direction. The interphase spacer and fittings tensile bending test platform simulates the dynamic process of the interphase spacer and its matching fittings when the line is galloping, so as to carry out research on the structure, strength, and fatigue performance of the wire and the interphase spacer.

Description

technical field [0001] The invention relates to the field of power transmission test equipment, in particular to a stretch-bending test platform for interphase spacers and fittings. Background technique [0002] At present, interphase spacers are widely used as the main anti-dance measure on transmission lines. The interphase spacer is mainly connected with the line conductors through supporting fittings, and is generally installed between conductors of different phases. The interphase spacer and supporting fittings are often transformed from the sub-wire spacer. At present, there is a set of national standard type test detection methods for ordinary sub-conductor spacers that are not used for interphase spacers, mainly testing the gripping force and centripetal force of sub-conductor spacers on sub-conductors, and the influence of sub-conductor vibration on clamps , because it only pays attention to the support function of the sub-conductor. However, there is no special ...

Problems solved by technology

[0006] In order to solve the technical problem that the test method of the ordinary sub-conductor spacer in the prior art is not applicable to the interphase spacer transformed from the sub-conductor spacer, the present invention provides an interphase spacer and fittings tensile bending test platform, the interphase The spacer and fittings tension bending test platform simulates the movement state of the wire and the interphase spacer when the line is galloping. On the one hand, it can simulate the dynamic process of the interphase spacer and its supporting fittings, so as to develop the dynamic characteristics of the wire and the interphase spacer. On the other hand, it is also possible to test the interphase spacers and fittings to verify whether they meet the structure, strength, and fatigue performance requirements applied in the anti-dancing process. By using this platform, the corresponding unreasonable fittings can be structural improvements
