Defining Resistance in Traction Motor Circuit According to Microprocessor Control System Data

Purpose: To develop methodology for determining the actual resistance of traction electric drive (TED) circuits a locomotive with power transmission and refined calculation voltage losses collector-brush apparatus according to microprocessor control system data. These data are necessary calculating characteristics as well its braking in modes. Methods: Methods machine theory, statistical processing regression analysis experimental were used. Results: Based on registration on-board diagnostics subsystem 20 sections 2TE116U TEP70BS diesel locomotives, methods factual value circuit proposed justified. The hypothesis distribution normal law possibility use mathematical expectation an estimated is confirmed. limits possible changes TED locomotives have been established. Practical significance: results obtained allow us clarify energy loss amounts when characteristics. Data limits, allowed exploitation, active change serviceable chains may be used operative circuit.
