When developing a high-speed contact suspension for railways electrified with alternating current, it is important to ensure that the electric rolling stock passes the neutral insert without turning off the current and without reducing the speed of movement. The article provides an analysis of previously developed devices in the field of power supply of electrified railways of single-phase alternating current, in which an attempt was made to pass an electric rolling stock of a neutral insert without disconnecting the load. The device of isolating coupling of a catenary and a neutral insert for high-speed railway lines electrified on alternating current is described. In this case, the passage of the neutral insert is carried out under current and braking of the electric rolling stock will not occur. Among other things, to improve the efficiency of high-speed contact suspension for railways electrified with alternating current, it is proposed to use new materials and new technologies that can be used in the device of insulating coupling of the catenary

Increase of freight traffic resulted in increased loads on traction substations and, respectively, in increase of their equipment failure risks. In the context of maintaining the required voltage level and power quality, which determine appropriate values in reliability for traction substation transformers, the article looks upon solving the problem of determination of reliability essential parameters. A proposed calculation model makes it possible to simplify the choice of electrical apparatus for uninterrupted power supply of electric rolling stock traction.

The paper describes the features of using the method of damped mechanical vibrations for express diagnostics of current collectors without removing from electric rolling stock roof. The proposed method is based on preliminary determination of the mechanical characteristics of the system of movable frames of a serviceable current collector in the factory. The paper describes a technique that can significantly reduce the complexity of conducting this type of research, increase the speed of measurement, and reduce the influence of the human factor.
