MODELING PROCESSES IN THE TRACTION NETWORK AND THE PARAMETERS FOR CONNECTING THE INTERLOCKING

Abstract

[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT The process of passing a train under the current along the branches of an insulating air gap of a DC traction network is studied, the reasons for disconnection of the branch to which the train enters are shown. To solve the tasks of increasing productivity and reducing costs in the work of electrified railway transport, a scheme for blocking the unauthorized operation of a high-speed switch is proposed. Using the modeling of the process of current variation in the network, the parameters of the additional coil of the magnetic circuit of the relay-differential shunt for connection of the locking device are determined. Keywords: railway, traction network, relay-differential shunt, blocking scheme, simulation modeling, coil parameters of magnetic circuit.
