Rel\u00e9s de estado s\u00f3lido<\/span><\/a><\/span> s\u00e3o componentes essenciais em sistemas de controle de temperatura (como sistemas de climatiza\u00e7\u00e3o, sistemas el\u00e9tricos de aquecimento de \u00e1gua, saunas, m\u00e1quinas de moldagem por inje\u00e7\u00e3o etc.) utilizados para ligar e desligar elementos de aquecimento de forma r\u00e1pida e precisa, garantindo um controle preciso da temperatura.<\/span><\/p>

Todos os rel\u00e9s de estado s\u00f3lido utilizam, principalmente, dois m\u00e9todos de controle: o controle de passagem por zero e o controle de acionamento aleat\u00f3rio.<\/span><\/p>

O processo de funcionamento do rel\u00e9 de estado s\u00f3lido com cruzamento por zero \u00e9 o seguinte: quando um sinal de entrada de controle \u00e9 recebido, a sa\u00edda do rel\u00e9 de estado s\u00f3lido n\u00e3o \u00e9 ativada imediatamente, mas aguarda que a tens\u00e3o sinusoidal CA caia at\u00e9 o ponto de cruzamento por zero antes de ativar o circuito de sa\u00edda. Quando o sinal de entrada \u00e9 removido, o rel\u00e9 de estado s\u00f3lido desliga-se automaticamente no pr\u00f3ximo ponto de passagem por zero.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

  1. Menor ru\u00eddo el\u00e9trico<\/b>:<\/span> Como os rel\u00e9s de estado s\u00f3lido (SSRs) com comuta\u00e7\u00e3o em ponto zero s\u00e3o ativados quando a tens\u00e3o est\u00e1 pr\u00f3xima de zero, as varia\u00e7\u00f5es repentinas na tens\u00e3o de carga s\u00e3o reduzidas. Isso ajuda a minimizar a interfer\u00eancia eletromagn\u00e9tica (EMI).<\/span><\/li>
  2. Corrente de irrup\u00e7\u00e3o reduzida para diversas cargas resistivas<\/b>: Conectar uma carga resistiva pr\u00f3ximo ao ponto de passagem por zero da tens\u00e3o reduz a corrente de irrup\u00e7\u00e3o inicial em compara\u00e7\u00e3o com lig\u00e1-la no ponto m\u00e1ximo da forma de onda CA.

    A principal desvantagem \u00e9 que os rel\u00e9s de estado s\u00f3lido (SSRs) n\u00e3o podem ser acionados em qualquer ponto de uma forma de onda de corrente alternada.<\/span><\/p>

    Em aplica\u00e7\u00f5es t\u00edpicas de aquecimento, esse atraso costuma ser insignificante.

    Quando uma tens\u00e3o de controle \u00e9 aplicada ao terminal de controle, o terminal de carga passa a conduzir imediatamente. Em outras palavras, ap\u00f3s a aplica\u00e7\u00e3o de um sinal de controle, o terminal de carga pode conduzir em praticamente qualquer ponto da forma de onda de corrente alternada.<\/span><\/p>

    Por exemplo, se um sinal de controle for aplicado quando a tens\u00e3o CA estiver pr\u00f3xima de sua tens\u00e3o de pico, o rel\u00e9 de estado s\u00f3lido de ativa\u00e7\u00e3o aleat\u00f3ria ser\u00e1 ativado nesse momento, sem esperar pelo pr\u00f3ximo ponto de passagem por zero.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

        Tanto os rel\u00e9s de estado s\u00f3lido com acionamento na passagem por zero quanto os de acionamento aleat\u00f3rio podem ser utilizados para o controle preciso de aquecedores e outras cargas.<\/span><\/p>
