A numerical control galloping experimental device for overhead transmission lines

Abstract

The invention discloses a numerical control swinging experimental device of the overhead transmission line. A support (1) is connected with a support ball linear guide pair (2) and support tooth bars (4), the support ball linear guide pair (2) is connected with connection boards (6) which are connected with first motor speed reducers (5) respectively, each first motor speed reducer (5) is connected with a vertical gear (14) which is engaged with the support tooth bar (4), a crossbeam (7) is connected with a crossbeam tooth bar (8) and a crossbeam ball linear guide pair (9), the crossbeam ball linear guide pair (9) is connected with a slide plate (11) which is connected with a second motor speed reducer (10), the second motor speed reducer (10) is connected with a horizontal gear (15) which is engaged with the crossbeam tooth bar (8), a first cable tow chain (3) is connected to the support (1) and the crossbeam (7), and a second cable tow chain (12) is connected with the slide plate (11) which is connected with the crossbeam and a lead clamp (16). The numerical control swinging experimental device is simple and practical in structure, high in carrying capacity, speed, positioning precision and reliability, smooth in transmission, and not limited by wind power in the natural environment.

Description

[0001] Technical field: [0002] The invention relates to a numerical control galloping experimental device for an overhead transmission line, which belongs to the field of design, operation, maintenance and experimental research of an overhead transmission line in a power system. [0003] Background technique: [0004] According to the published literature, so far, there is no patent for the numerical control galloping experimental device of overhead transmission lines, and other related patents are described as follows: [0005] Three-degree-of-freedom galloping wind tunnel test device for multi-split ice-coated conductors (application number 201510178134.7) [0006] It is characterized in that it includes a multi-split ice-coated wire segment model, and columns fixedly installed on both sides of the wind tunnel test section. An upper beam and a lower beam are installed between the columns on the same side and can be moved up and down to adjust the position. A vertical sprin...

Problems solved by technology

This device has certain limitations, and it must be completely placed inside the wind tunnel, relying entirely on the force of the wind to provide its movement power; its disadvantage is that it is impossible to control or adjust the galloping frequency and amplitude of the wires, The gear span (the distance between the two columns) is also very small, the bearing capacity is small, the speed is slow, the transmission is not stable, the positioning accuracy is low, the bearing capacity is weak, the reliability is low, and it is subject to the wind force in the natural environment.
