The successful compleon of the second stage of testing a new switched-reluctance drive

           Within cooperation between JSC RZD, YuRGTU(NPI) and TEC "POLYTECH" in the spere of creation of electric drives for an operating and perspective rolling stock in our engineering company proceeds work on creation of the new switched-reluctance drive of the compressor of the alternating current train. It provides a mode of start-up of the compressor, maintenance of nominal frequency of rotation under loading, protective shutdown in emergency operation and is alternative to the existing drive on the basis of the serial asynchronous electric motor. Calculations are executed, design documentation is developed and the experimental sample of the switched-reluctance electric drive is made. On our experimental base the test bench for working off and drive tests is constructed.

            The first stage of bench tests was finished at the beginning of April, 2013. After necessary preparation and adaptation of switched-reluctance electric drive software we started the following stage. At the beginning of May, 2013 on our experimental base also the second stage of bench tests of the drive successfully came to the end. The received results of tests allow to make the conclusion about compliance of the new drive of initial design documentation, to design technical characteristics and safety requirements.

                      Summaryof bench tests established readiness of the new compressor drive for the following stage - to trial runs in real conditions of operatioin on an operating electric locomotive of JSC RZD.
