TRACTION ELECTRIC DRIVE FOR COMBINED POWER SUPPLIED MINE LOCOMOTIVE

摘要

The invention relates to electric traction and is intended primarily for use on direct current mine locomotives. The purpose of the invention is to increase reliability. The traction motor drive of a mine locomotive contains a current collector 8 connected in series, an electromechanical accumulator 2 made in the form of a flywheel 3 on a shaft of a direct current electric machine, a current sensor 14 and a traction motor 1, a cathode connected to a current collector, a switching contactor, a coil which is connected to the current collector. Two closing and two opening contacts of the contactor form a reverser, the diagonal of which includes the electric winding of the electric machine. The device also includes a current setting unit 18 connected in series, a comparison unit 19, a pulse-width converter 20 and an inverter 21, the output of which is connected to the control input of the adjustable power supply 12, to the output of which is connected the excitation winding 11 of the DC electric machine. 1 hp f-ly, 1 ill.
