Description

Предлагаетс  устройство дл  реверсировани  электропривода системы Леонарда.A device is proposed for reversing the Leonard electric drive.

Отличительной особенностью нрел,ложенного устройства  в-л етс  обеспечение реверса двигател  кратковременным отключением цепи Ю-чбуждени  генератора конечным выключателем и изменением за это врем  пол рности щеток, которые сохран ют эту пол рность и после включени  цепи возбуждени .A distinctive feature of the nrel device is the provision of motor reversal by briefly disconnecting the U-excitation circuit of the generator with a limit switch and changing the polarity of the brushes during this time, which retain this polarity even after switching on the excitation circuit.

Изменение пол рности достигаетс  смещением щеток на некоторый угол. При обрыве п,епи возбуждеггм  конечным вьп лючателем напр жение на генераторе надает и старювитс  меньше противоэлектродвижущей силы двигател . За счет последней ток мен ет свое направление и двигатель тормозитс .The change in polarity is achieved by shifting the brushes at a certain angle. In the event of a breakage of a switch, an excitement with a finite switch, the voltage on the generator imposes and reduces the counter-electromotive force of the engine. Due to the latter, the current changes its direction and the motor slows down.

Так как щетки генератора сдвинуты , пол рность на них при падении напр жени  на генераторе мен етс  за счет реакции  кор . ПриSince the generator brushes are shifted, the polarity of the brushes on them when the voltage drops across the generator changes due to the reaction of the core. With
