Samer A. Control of a power supply of miner contact electric locomotives at prevention of electric categories in current collector contacts

The dissertation is devoted to creation of methods and algorithms of control by a power supply of miner contact electric locomotives at use of means of prevention of electric categories in токосъемных devices by a principle of anticipatory interruption of an electric power supply. Due to researches in work it is established, that for required restriction of negative influence of faltering character of a pressure voltage of an electric power supply on work of a contact electric locomotive at use of means of prevention of electric categories expediently use of the smoothing filter and separate valve shuntings of an anchor and a winding of excitation of traction engines. In result the technique of realization of the greatest inductance of a smoothing throttle is offered at the set restrictions of its dimensional and electric parameters. The algorithm of management is proved by a power supply of a miner electric locomotive on the basis of forecasting with use of a mode of a faltering power supply of traction engines with compulsory anticipatory interruption of the current consumed from a contact network. Are developed structure of a control system by a power supply of miner electric locomotives from a contact network in conditions of the collieries dangerous on gas and a dust.
