Abstract

FIELD: electric transportation facilities. SUBSTANCE: proposed device includes contactors 1, 3, 15, 17 connected to armature windings of motors 2, 4 and contactors 11, 12 connected to excitation windings 6, 8 between which diode 7 is placed and shunted by diode 10. Thyristor-pulse converters 6, 16 are placed between armatures 2, 4 and excitation windings 6, 8. Armature windings 2, 4 together with contactors 1, 3 are shunted by diodes 13, 14 correspondingly. Connection points of contactors 1, 3 and armatures 2, 4 are connected to minus pole of power supply source 9 via diodes 18, 19 connected in backward direction. Thyristor 20 and resistor 21 connected in series are placed between connection point of diodes 13, 14 and minus of power supply source 9. EFFECT: increase of maximum permissible initial rate of recuperative brake thanks to usage of parallel and series connections of armatures and excitation windings of traction motors.

Изобретение относится к области тягового электропривода и может быть использовано на электротранспортных средствах. Технический результат - повышение максимально допустимой начальной скорости рекуперативного торможения за счет применения параллельного и последовательного соединения якорей и обмоток возбуждения тяговых двигателей. Устройство содержит контакторы, которые подключены к якорным обмоткам двигателей, и контакторы, соединенные с обмотками возбуждения, между которыми включен диод, и шунтированными диодом. Между якорями и обмотками возбуждения включены тиристорно-импульсные преобразователи. Якорные обмотки вместе с контакторами шунтированы диодами соответственно. Точки соединения контакторов с якорями подключаются к минусовому полюсу источника питания через диоды, включенные в обратном направлении. Между точкой соединения диодов и минусом источника включены последовательно соединенные тиристор и резистор.The invention relates to the field of traction electric drive and can be used on electric vehicles. The technical result is an increase in the maximum permissible initial regenerative braking speed due to the use of parallel and serial connection of anchors and field windings of traction motors. The device contains contactors that are connected to the armature windings of the motors, and contactors connected to field windings, between which a diode is connected, and shunted diodes. Between the armature and field windings, thyristor-pulse converters are included. Anchor windings together with contactors are shunted by diodes, respectively. The connection points of the contactors with the anchors are connected to the negative pole of the power source through diodes that are connected in the opposite direction. Between the diode connection point and the source minus, thyristor and resistor are connected in series.
