Abstract
"RELé DE GáS ELETRÈNICO". O Relé de Gás Eletrónico para proteção e comando de transformador elétrico de potência imerso em óleo isolante, objeto da presente invenção, trata-se de um dispositivo de captura e retenção de gases (10) desprendidos do meio líquido (2) do óleo isolante para acionar um módulo eletrónico transmissor de dados por meio de um sensor eletrónico, para enviar sinais elétricos proporcionais à variação volumétrica da camada dos tais gases (10) desprendidos do meio líquido (2) do óleo isolante que são capturados e retidos no seu corpo fabricado de material metálico. O relé de gás eletrónico (6), objeto da presente invenção, cujo modelo construtivo é conforme a Figura 2, se destina à instalação conforme Figura 1A em linha no tubo de interligação (5) do tanque principal (3) com o tanque conservador (4). O relé de gás eletrónico (7), objeto da presente invenção, cujo modelo construtivo é conforme a Figura 3, se destina à instalação conforme Figura 1B em ponto alto no tubo de interligação (5) do tanque principal (3) com o tanque conservador (4), sendo munido com uma válvula de bloqueio (8) que permite o acesso ao relé de gás eletrónico (7) sem necessidade de desligamento do transformador. O relé de gás eletrónico, tanto no modelo construtivo conforme a Figura 2 ou como no modelo construtivo conforme a Figura 3, objeto da presente invenção, tem o princípio de funcionamento baseado em sensores eletrónicos para identificação da variação volumétrica da camada de gases (10) desprendidos do óleo isolante com o modal capacitivo, magneto-restritivo, ultra-som, refração ótica da radiação infravermelho ou reflexão ótica do raio laser, conforme as Figuras 4A, 4B, 4C, 5A, 5B, 5C, 6A, 6B, 6C, 7A, 7B, 7C, 8A, 8B e 8C.
