Yashchuk K. The increasing of reliability of automatic blocking system in conditions of influence of high levels of traction currents and powerful pulsed interference

The object of study - the process of rail circuits working under the influence of powerful pulsed interference and high levels of traction current. The aim of the thesis research is to improve the reliability of automatic blocking system under the impact of high levels of traction currents and powerful pulsed interference. Placed scientific problem has been solved with the correct use of modern mathematical apparatus. Scientific novelty: the first mathematical model of a parametric generator with noncollinear magnetic fields as a power supply and protective equipment of rail circuits; improved the structure of parametric generator, characterized by the presence of energy-intensive elements; improved the method of calculating the distribution of potentials and currents in the rail network, featuring a presentation of the overall scheme of each chain rails; improved search method most appropriate locations throttle-transformators. The results has been used in the performance of research works in the educational process DNUZT. As a result of theses at "Transsvyaz" (Kharkiv) has been produced parametric generator frequency PG 50:50 reductions, that has been tested in the factory, at the research laboratory of ATZ DNUZT and has been transferred to the sixth-distance signaling and communication Prydniprivsk Railway, confirmed that the relevant acts listed in the annexes. The research results has been intended for use in the field of railway transport.
