Description

Предлагаетс  устройство дл  электрического автоматического управлени  регулируемым шунювым двигателем, предназначенным дл  работы на двух нанр жени х. В указанном двигателе, с целью автоматического безреостатного перехода двигател  с одного напр жени  на другое, применено присоединеное параллельно к цепи  кор  двигател  вольтметровое реле, автоматически переключающее под вли нием повышающегос  или понижающегос  до соответственной величины напр жени  на  коре посредством р да вспомогательных реле  корь двигател  на то или иное напр жение.A device for electric automatic control of an adjustable shun engine is proposed for operating on two lines. In the indicated engine, for the purpose of automatic motorless transition of the engine from one voltage to another, a voltmeter relay connected in parallel to the motor core was applied, automatically switching under the influence of increasing or decreasing core voltage to the corresponding core voltage one voltage or another.

Предлагаемое устройство, электрическа  схема которого изображена на чертеже , в основном состоит из д1вигател , снабженного щунтовой обмоткой Ш; переключател  (реле) D с одного напр жени  на другое, кнопочного управлени  а, Ь, с, d, вольтметрового реле Р, присоединенного параллельно к цепи  кор , и р да вспомогательных промежуточных реле, в том числе р, i и F. Перед моментом переключени  на соответствующее напр жение двигатель разгон етс  или затормаживаетс  так, чтобы противоэлектродвижуща  сила, индуктируема  в отключенном от сети на короткий промежуток времени  коре, достигла, примерно, тех же значений, что и напр жение сети, к которой подключаетс   корь.The proposed device, the electrical circuit of which is shown in the drawing, mainly consists of a dvigatel equipped with a shunt winding W; switch (relay) D from one voltage to another, push-button control a, b, c, d, voltmeter relay P connected in parallel to the core circuit, and a number of auxiliary intermediate relays, including p, i and F. Before the moment switching to the appropriate voltage, the motor is accelerated or slowed down so that the counter electromotive force induced in the core disconnected from the network for a short period of time reaches approximately the same values as the voltage of the network to which the measles are connected.

Переход с высокого напр жени  на более низкое осуществл етс  отключением  кор  двигател  от сети и уменьщением возбуждени , достигаемым с помощью комбинированного реостата Е, управл емого соленоидами 1 и 2, которые в свою очередь включаютс  и выключаютс  кнопками а, b VLC кнопочного управлени . Кроме того, при этом необходимо нажимать кнопку d, котора  дает возможность через добавочное реле F вольтметровому реле Р замкнуть цепь вспомогательного реле р, которое в свою очередь замкнет цепь реле 1-Д вклюающего двигатель на низкое напр жение.Switching from high voltage to lower voltage is accomplished by disconnecting the motor core from the mains and reducing the excitation achieved by using a combined rheostat E controlled by solenoids 1 and 2, which in turn are turned on and off by buttons a, b VLC button control. In addition, it is necessary to press the button d, which, through the additional relay F, allows the voltmeter relay P to close the auxiliary relay p circuit, which in turn closes the 1-D relay circuit including the motor to low voltage.

Переход двигател  на более высокое напр жение заключаетс  в следующем: двигатель, работавший на низком наThe transition of the engine to a higher voltage is as follows: an engine operating at low
