Abstract

"DISJUNTOR". Para uso em circuito de energia/carga formado por uma fonte de alimentação de corrente alternada trifásica e uma carga conectada à fonte de alimentação por meio de três linhas de energia vivas, disjuntor esse que compreende um circuito de disparo, o qual inclui chaves normalmente abertas conectadas em série com as respectivas linhas de energia voltadas para a fonte de alimentação, um transformador que tem pelo menos três enrolamentos primários equilibrados conectados subseq³entemente em série ao longo das respectivas linhas de energia' e um enrolamento secundário, incluindo dispositivo de comparação de voltagem conectado ao enrolamento secundário voltagem induzida para comparar uma o transformador com uma voltagem de referência capaz, no caso de falha de fuga para a terra no circuito de energia/carga, capaz de enviar um sinal de disparo para que o circuito de disparo abra as chaves a fim de desligar a carga da fonte de alimentação, bem como uma passagem de circuito para detectar e comparar duas voltagens de fase a fase das linhas de energia entre si e então, no caso de uma falha de desequilíbrio de voltagem no circuito de energia/carga, simular uma condição de falha de fuga para o transformador detectar e o dispositivo de comparação de voltagem enviar um dito sinal de disparo.
