Zavgorodnyj A. Increasing of rail circuits functional safety by of their electromagnetic compatibility with a traction network.

In the thesis the scientific and practical task of increasing of rail circuits functional safety by ensuring of their electromagnetic compatibility with a traction network has been carried out that allows to increase traffic safety of high-speed trains. For the first time parameters of statistical distribution of harmonious handicapes of a traction current as non-stationary casual process was determined, the mathematical model of distribution of harmonious handicapes in a rail line, the mathematical model of distribution of an electromagnetic field around of a rail and the mathematical model of electromagnetic influence of a traction network on rail circuits were developed,. Results of work are used for carrying out of test procedure for new types of a rolling stock on electromagnetic compatibility with lines of railway signalization systems.
