Embodiment Construction

[0028] In order to better understand the present invention, the present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] Since the detection data in the prior art is not intuitive enough and accurate enough; the present invention provides such Figure 1-Figure 4 The scheme shown:

[0031] A crimping quality inspection device for strain-clamp aluminum stranded wires, comprising a host computer...

Abstract

The invention discloses a strain clamp aluminum stranded wire press-fitting quality detection device and method. The detection device comprises a steel anchor, aluminum stranded wires, an external detection probe and a digital ultrasonic detection device, wherein the steel anchor and the aluminum stranded wires are press-fitted, the external detection probe is closely attached to press-fitting parts for detection, the digital ultrasonic detection device is electrically connected with the external detection probe, and a to-be-detected surface is uniformly coated with a coupling agent. The detection method comprises detection of the press-fitting parts between the steel anchor and steel cores of the aluminum stranded wires and detection of a press-fitting part between the steel anchor and analuminum bushing. The strain clamp aluminum stranded wire press-fitting quality detection device and method aim to detect press-fitting quality, to be specific, internal conditions of the press-fitting parts are visually displayed in the form of an image, then a press-fitting defect is discovered, and therefore the press-fitting quality is accurately judged.

Description

technical field [0001] The invention belongs to the technical field of transmission line safety detection in the electric power industry, and in particular relates to a crimping quality detection device and method for an aluminum stranded wire of a tension clamp. Background technique [0002] At present, my country's power transmission industry is continuously developing UHV smart and strong power grids, and has laid out the construction of grid structures with multiple voltage levels such as ±800kV and 1000kV, and AC and DC complementarity. Due to the intricate structure of the power grid, there are often "three-span" lines across expressways, railways, and important transmission channels, which have a severe test on the tension clamps of the transmission line's tension towers. If the quality of the clamp crimping is not up to standard, There are certain safety hazards to the operation of the transmission line in the later stage, so it is very necessary to carry out online ...
