IDENTIFICATION OF THE CAUSES OF CONTACT WIRE FRACTURE ON THE ELEMENTS OF SECTIONALIZING DEVICES USING FRACTOGRAPHIC STUDY AND SPECTRAL ANALYSIS
Abstract and keywords
Abstract (English):
Objective: to establish the causes of the fracture of the arc-extinguishing horns of the sectional insulators of the contact network. Methods: factographic analysis of the fracture surface and spectral analysis of the wire. Results: the paper presents the results of the factographic analysis of the fracture surface and spectral analysis of the wires of the contact network. Practical significance: the research results will be used in the development of technical specifications for the manufacture of contact shaped wires, as well as requirements for the installation and adjustment of sectional insulators.

Keywords:
sectional insulator, coupling, arc-extinguishing horn, contact wire, fractographic study, spectral analysis, current collector
