Description
При электрическом торможении асинхронных электродвигателей путем подключени сопротивлени к статорной обмотке с последующим отключением электродвигател вместе с этим сопротивлением от питающей сети не представл етс возможным обеспечить быстрое торможение электропривода.When electrically braking asynchronous electric motors by connecting resistance to the stator winding and then disconnecting the electric motor together with this resistance from the mains supply, it is not possible to ensure rapid deceleration of the electric drive.
Предлагаемый способ электрического торможени более соверщенен , так как при применении его существенно уменьшаетс врем и путь торможени . Это достигаетс в результате того, что торможение двигател выполн ют в две ступени. На первой ступени статорную обмотку с подключенным к ней сопротивлением отключают от сети, а на второй ступени осуществл ют динамическое торможение электродвигател путем подачи в его статорную обмотку посто нпого тока.The proposed method of electric braking is more perfect, since when applied it significantly reduces the time and the way of braking. This is achieved as a result of engine braking being performed in two stages. At the first stage, the stator winding with the resistance connected to it is disconnected from the network, and at the second stage, the motor is dynamically braked by applying direct current to its stator winding.

На первой ступени к статорной обмотке посредством контактора 2 подключаетс активное сопротивление 5, после чего отключаетс линейный контактор 4, который отсоедин ет двигатель, вместе с подключенным сопротивлением 3 от питающей сети.In the first stage, active resistance 5 is connected to the stator winding by means of a contactor 2, after which the linear contactor 4 is disconnected, which disconnects the motor, together with the connected resistance 3 from the mains.
На второй ступени включаетс контактор 5 и в обмотку статора через трансформатор 6 и выпр митель 7 подаетс посто нный ток, с целью осуществлени динамического торможени .At the second stage, the contactor 5 is turned on and a constant current is supplied to the stator winding through the transformer 6 and the rectifier 7, in order to carry out dynamic braking.
После окончани торможени элемент времени реле 8 отключает контактор 5.After the end of braking, the time element of the relay 8 turns off the contactor 5.
