DIAGNOSTICS SYSTEM FOR THE POWER CONTROL CIRCUIT IN THE MAINLINE LOCOMOTIVE SERIES 2ТЭ116У
He assessment results of the technical condition relating the control circuit of the mainline locomotive series 2TЭ116У with the DC traction electric drive ED-118A are presented. An increase in operational reliability of electric equipment of electromechanical transport systems is to a large extent provided through introducing advanced means of automated control and technical diagnostics of the power control chains. A key objective in developing an automated diagnostics system for the technical condition of a power control chain to the main cargo locomotive of the 2ТЭ116У series is the choice of information-based diagnosing parameters. The choice of the most information-bearing diagnostic parameters to control the technical conditions of the power control circuit can be made using parametric modeling and tabular methods for the choice of parameters. Using the parametric model of the locomotive control circuit 2TЭ116У, we obtained the energy diagnostics parameters which help to continuously monitor the faults and failures in contactors, auxiliary electric machines in the power control circuits of diesel locomotives.
