Description

Изобретение относитс  к области Электротехники, а именно к устройствам дл  управлени  сериесными электродвигател ми , и может найти применение в системах автоматического регулировани  электропередач тепловозов и других автономных т говых приводов посто нного тока.The invention relates to the field of Electrical Engineering, in particular, to devices for controlling serial electric motors, and can be used in automatic transmission control systems of diesel locomotives and other autonomous DC traction drives.

Известно устройство дл  управлени  сериесным электродвигателем, в котором ток воэбуждени  двигател  регулируетс  в функции тока  кор  путем сравнени  этих токов между собой l .A device for controlling a serial electric motor is known in which the motor excitation current is regulated as a function of the current of the core by comparing these currents with each other l.

Отсутствие запщты по услови м коммутации заставл ет ограничивать диапазон изменени  частоты вращени  двигател .The absence of a switch over the conditions of switching forces to limit the range of variation of the rotational speed of the engine.

Наиболее близким техническим реше:нием к изобретению  вл етс  устройство дл  управлени  сериесным электродвигателем , содержащее последовательно соединенные регул тор возбуждени  и блок сравнени , датчик тока воэбуждени  и датчик тока  кор , подключенные-.ко входу блока сравнени  через блок ограничени  2.The closest technical solution to the invention is a device for controlling a serial electric motor, comprising a series-connected excitation controller and a comparison unit, an excitation current sensor and a core current sensor connected to the input of the comparison unit through the limiting unit 2.

Однако настройка этой системы осуществл етс  совместно с настройкой внешней характеристики генератора , что усложн ет как процесс настройки , так и подбор характеристик.However, the adjustment of this system is carried out in conjunction with the adjustment of the external characteristics of the generator, which complicates both the tuning process and the selection of characteristics.

Кроме того, невысока  точность устройства требует применени  дополнительных усилителей. Скоростной диапазон привода ограничивают из опасени  превзойти предел по комт тационной устой .ивости двигателей при In addition, the low accuracy of the device requires the use of additional amplifiers. The speed range of the drive is limited, for fear of exceeding the limit on the switching stability of the engines when

0 уменьшении тока возбуждени .0 a decrease in excitation current.

Целью изобретени   вл етс  расширение диапазона регулировани  скорости двигател .The aim of the invention is to expand the range of engine speed control.

Это достигаетс  тем,что в устрой5 ство введены блок делени  и дополнительный блок ограничени  тока, причем входы блока делени  подключены к выходам датчиков тока  кор  и возбуждени , а выход через дополнитель0 ный блок ограничени  тока соединен со входом блока сравнени .This is achieved by introducing a dividing unit and an additional current limiting unit into the device, the inputs of the dividing unit being connected to the outputs of the current and excitation current sensors, and the output through an additional current limiting unit connected to the input of the comparator unit.

На чертеже представлено предлагаемое устройство дл  управлени  сериесным электродвигателем.The drawing shows the proposed device for controlling a series-produced electric motor.
