Abstract
Изобретение относитс к электротехнике и может быть использовано дл управлени электродвигател ми посто нного тока. Целью изобретени вл етс повышение энергетических показателей и надежности. Электропривод содержит трансформатор 5, включенный между сетью и преобразователем 2. Выход преобразовател 2 подключен к корной обмотке электродвигател 1. Якорную обмотку электродвигател 1 шунтирует тиристор 20. Вход блока 12 сравнени заданной и фактической реактивной мощности подключен к датчику 11 реактивной мощности. Выход блока 12 соединен со вторым замыкающим ключом 16. В данном электроприводе обеспечиваетс открытие шунтирующего тиристора 20 и регулирование угла управлени преобразовател 2 по рассогласованию фактической и заданной реактивной мощности сети. 5 ил.The invention relates to electrical engineering and can be used to control DC motors. The aim of the invention is to increase energy performance and reliability. The drive contains a transformer 5 connected between the network and converter 2. The output of converter 2 is connected to the main winding of electric motor 1. The anchor winding of electric motor 1 is shunted by thyristor 20. The input of unit 12 comparing the set and actual reactive power is connected to the sensor 11 of reactive power. The output of unit 12 is connected to the second closing key 16. In this drive, the shunt thyristor 20 is opened and the control angle of converter 2 is adjusted by the mismatch of the actual and predetermined reactive power of the network. 5 il.
