Abstract

"APARELHO DE COMUTAçãO SìNCRONA". Um aparelho de comutação síncrona para detectar uma voltagem fonte de cada fase, para fechar cada fase com uma defasagem elétrica predeterminada para cada fase, que inclui dispositivos de comutação 1a-1c fornecidos, um para cada fase, para abrir e fechar uma carga de impedância, mecanismos de comutação 2a-2c para fechar e abrir os dispositivos de comutação 1a-1c para cada fase, transformadores de medição 5a-5c, para medir voltagens fonte de fases respectivas, e voltagens de fase para fase, e dispositivos de controle de fase 42, cada um, para emitir um comando para energizar a carga de impedância com uma defasagem elétrica em uma faixa predeterminada para cada fase ao detectar um ponto zero de uma voltagem fonte de cada fase, ou um ponto zero de cada voltagem de fase para fase.
