Abstract
Изобретение относитс к электротехнике . Цель изобретени - упрощение и повышение технико-экономических показателей . Дл этого в устройство дл пуска энергосистемы переменного тока, содержащее синхронную машину 1 с датчиком положени ротора 2, имеющую основную обмотку статора 4 и отпайки 14. систему возбуждени введены два коммутационных аппарата 18 и 19. Дл пуска включаютс вначале выключатели 12, 10, коммутационный аппарат 19. В результате обмотка возбуждени 15 оказываетс включенной последовательно между выпр мителем 7 и выпр мителем 8. Последний переводитс в режим инвертировани . Синхронна машина разворачиваетс в структуре вентильного двигател . По достижению промежуточной частоты отключаетс выключатель 12 и выключаетс аппарат 13, подключа отпайки обмотки статора. Ротор разгон етс до частоты выше синхронной, затем обмотки статора отключают системы возбуждени и подключаютс выключателем 5 к сети. 3 ил.The invention relates to electrical engineering. The purpose of the invention is to simplify and improve technical and economic indicators. To do this, the device for starting the AC power system, which contains a synchronous machine 1 with a rotor position sensor 2, has a main stator winding 4 and tapings 14. The excitation system introduces two switching devices 18 and 19. Switches 12, 10, the switching device first are turned on for starting. 19. As a result, the field winding 15 is connected in series between the rectifier 7 and the rectifier 8. The latter is switched to the inversion mode. The synchronous machine unfolds in the structure of a valve motor. When the intermediate frequency is reached, the switch 12 is turned off and the device 13 is turned off, connecting the stator winding. The rotor is accelerated to a frequency higher than the synchronous one, then the stator windings turn off the excitation systems and connect the switch 5 to the mains. 3 il.
