Abstract

The invention discloses a sample preparation device and method for wire and cable metal wire chemical component analysis, and relates to the technical field of overhead conductor aluminum wire chemical component analysis, the main structure of the sample preparation device comprises a driving mechanism, a winding mechanism and a driven mechanism; and the winding mechanism is detachably arranged between the driving mechanism and the driven mechanism. According to the sample preparation device for wire and cable metal wire chemical component analysis, the problem that the excitation section sizeof the small-section aluminum wire does not meet the requirement can be effectively solved, excitation is insufficient, and a direct-reading spectrometer cannot be applied to carry out accurate testing, the problem that errors are large due to insufficient excitation of the small-section aluminum wire is avoided, the situation that evaluation of test indexes is affected due to deviation of chemical component index data of the aluminum wire is avoided, and the problems of large workload, low efficiency and long consumed time due to the fact that a chemical analysis method is adopted and the aluminum wire is molten at high temperature are avoided.

Description

technical field [0001] The invention relates to the technical field of chemical composition analysis of overhead conductor aluminum wires, in particular to a sample preparation device and method for chemical composition analysis of metal wires of electric wires and cables. Background technique [0002] As the main carrier of power transmission, wires and cables are widely used in power systems. Common types include power cables and bare wires. As the most basic and indispensable main component for the function of current information transmission, the conductor is generally made of copper, aluminum and other non-ferrous metal wires with excellent electrical conductivity. The quality of wire and cable metal wire directly affects the quality of the project and the safety of life and property of consumers. [0003] Chemical composition is the main factor determining the performance and quality of metallic materials. The chemical composition of copper, aluminum and other wires ...
