Abstract

The aim of this article is to analyze the reasons for deflagration of the contact wires on the neutral section.

Methodology of the article is based on the use of the theory of the electrical breakdown of gases.

The relevance of this work was caused by the fact, that at DEFLAGRATE contact wire of contact network on the neutral section, happens disajustment of a contact network on the adjacent tension length. To address the impacts requires considerable time and material costs. Also there is a damage of pantographs and other roof equipment of electric rolling stock, which leads to long delays of trains.

The analysis and justification of possible reasons for burnout the contact wire of contact network on the neutral section and the proposed organizational and technical measures for prevention of the burnout  of the contact wires on the neutral section in cases of passing them electric train without disconnecting the current. As well as means designed to reduce the amount of damage to the contact network and roof equipment of electric train in case of stratification the contact wires.

Improving the reliability of operation of neutral section will reduce the losses caused by damage of the contact grid and roof equipment of electric train when the wire breaks contact
