Description

Предлагаемое устройство предназначено дл  автоматического асинхронного пуска синхронных двигателей малой мощности, которые допускают пр мой пуск от полного напр жени  сети и имеют схему регулировани  возбуждени  от полупроводниковых выпр мителей, и осуществл ет , подобно известным устройствам того же целевого назначени , включение обмотки ротора синхронного двигател  на пусковое сопротивление в начале пуска и присоединение ее к источнику питани  в конце пуска. Отличительна  особенность его состоит в использовании дл  подачи сигнала на переключение релейного магнитного усилител , обмотка смещени  которого подключена через выпр митель к сети, а обмотка управлени  - через выпр митель к цепи ротора.The proposed device is intended for automatic asynchronous start-up of low-power synchronous motors, which allow direct start from a full network voltage and have an excitation control circuit from semiconductor rectifiers, and, like the known devices of the same purpose, turn on the rotor winding of the synchronous motor starting resistance at the start of the start and connecting it to the power supply at the end of the start. Its distinctive feature is to use a signal to switch a relay magnetic amplifier, the bias winding of which is connected via a rectifier to the network, and the control winding through a rectifier to the rotor circuit.

Использованием релейного магнитного усилител  достигаетс  повыщение надежности и упрощение наладки схемы.The use of a relay magnetic amplifier results in increased reliability and simplified circuit setup.

На чертеже изображена принципиальна  электрическа  схема предлагаемого устройства.The drawing shows a circuit diagram of the proposed device.

Прин ты следзющие обозначени : ОС-обмотка статора синхронного двигател ; ОВ - его обмотка возбуждени ; БР - блок регулировани  возбуждени ; 5, - полупроводниковые выпр мители; AT - автотрансформатор; R - сопротивление уставки; R -- активное сопротивление; УИУ - релейный магнитный усилитель с обмотками; управлени  W , смещени  W,,„ переменного тика Wц-, и положительной обратной св зи Woe; Р - электромагнитное реле; БК - блок-контакт контактора .The following symbols should be adopted: OS-stator winding of the synchronous motor; OB is its field winding; BR - excitation control unit; 5, - semiconductor rectifiers; AT - autotransformer; R is the setpoint resistance; R - active resistance; MCD - relay magnetic amplifier with windings; control W, offset W ,, „variable tick Wц-, and positive feedback Woe; P - electromagnetic relay; BK - contactor block contact.

При запуске двигател  его обмотка возбуждени  ОВ включена на сопротивление R. а выпр митель 5, отключен от нее контактами реле Р,  вл ющегос  нагрузкой релейного магнитного усилител  МУ.When the engine is started, its excitation winding OB is connected to the resistance R. and the rectifier 5 is disconnected from it by the contacts of the relay P, which is the load of the relay magnetic amplifier MU.

Обмотка управлени  Wу усилител  питаетс  через выпр митель В-2 напр жением ротора, снимаемьтм с обмотки возбуждени  ОВ, а обмоткаThe control winding of the Woo amplifier is fed through the B-2 rectifier by the voltage of the rotor, removed from the field winding of the RV, and the winding
