As l\u00e2mpadas fluorescentes tubulares de duplo pino \u00e0 prova de explos\u00e3o com seguran\u00e7a acrescida s\u00e3o amplamente utilizadas em ambientes inflam\u00e1veis e explosivos, como as ind\u00fastrias petrol\u00edfera e qu\u00edmica. A sua estrutura inclui normalmente um inv\u00f3lucro, cobertura de prote\u00e7\u00e3o, suporte da l\u00e2mpada, balastro, tubo fluorescente, interrutor de isolamento e outros componentes. Em atmosferas explosivas, as l\u00e2mpadas fluorescentes com um n\u00edvel de prote\u00e7\u00e3o do equipamento (EPL) de \u201cGb\u201d s\u00e3o as mais amplamente aplicadas.<\/p>\n\n\n\n

Os principais requisitos de seguran\u00e7a \u00e0 prova de explos\u00e3o para estas l\u00e2mpadas fluorescentes \u00e0 prova de explos\u00e3o incluem:<\/h2>\n\n\n\n
    \n
  1. Estabilidade T\u00e9rmica de Materiais N\u00e3o-Met\u00e1licos<\/strong>
    A estabilidade t\u00e9rmica a longo prazo dos inv\u00f3lucros n\u00e3o met\u00e1licos e dos componentes isolantes deve exceder a temperatura m\u00e1xima de funcionamento em pelo menos 20K, com um requisito m\u00ednimo de 80\u00b0C.<\/li>\n\n\n\n
  2. Dist\u00e2ncia entre o tubo e a cobertura de prote\u00e7\u00e3o<\/strong>
    A dist\u00e2ncia entre o tubo fluorescente e a cobertura de prote\u00e7\u00e3o n\u00e3o deve ser inferior a 5 mm. Para coberturas transparentes tubulares coaxiais, a dist\u00e2ncia interna m\u00ednima do tubo deve ser de 2 mm.<\/li>\n\n\n\n
  3. Folga el\u00e9ctrica e dist\u00e2ncia de fuga<\/strong>
    As folgas el\u00e9ctricas e as dist\u00e2ncias de fuga devem estar em conformidade com as Cl\u00e1usulas 4.3\/4.4 do GB\/T 3836.3-2021.<\/li>\n\n\n\n
  4. Liga\u00e7\u00e3o em paralelo dos pinos da l\u00e2mpada<\/strong>
    Quando ligados ao suporte da l\u00e2mpada ou diretamente ligados por fios no interior da lumin\u00e1ria, os dois pinos da cabe\u00e7a de l\u00e2mpada devem ser ligados em paralelo. Para efeitos de redund\u00e2ncia, cada pino deve ter uma capacidade de transporte de corrente igual \u00e0 corrente nominal da l\u00e2mpada.<\/li>\n\n\n\n
  5. Liga\u00e7\u00f5es el\u00e9ctricas independentes<\/strong>
    O sistema de liga\u00e7\u00e3o el\u00e9ctrica de cada pino deve funcionar independentemente dos outros pinos.<\/li>\n\n\n\n
  6. Preven\u00e7\u00e3o da deforma\u00e7\u00e3o dos pinos<\/strong>
    Os suportes dos pinos devem minimizar a deforma\u00e7\u00e3o quando \u00e9 aplicada uma press\u00e3o de contacto lateral aos pinos.<\/li>\n\n\n\n
  7. Liga\u00e7\u00f5es fi\u00e1veis em condi\u00e7\u00f5es dif\u00edceis<\/strong>
    As liga\u00e7\u00f5es el\u00e9ctricas de cada pino entre o tubo e o casquilho da l\u00e2mpada devem manter-se fi\u00e1veis em condi\u00e7\u00f5es de corros\u00e3o e vibra\u00e7\u00e3o.<\/li>\n\n\n\n
  8. Limite de temperatura ambiente para balastros electr\u00f3nicos<\/strong>
    Para as l\u00e2mpadas fluorescentes tubulares de dois pinos que utilizam balastros electr\u00f3nicos, a temperatura ambiente m\u00e1xima n\u00e3o deve exceder 60\u00b0C.<\/li>\n\n\n\n
  9. Classifica\u00e7\u00e3o da temperatura<\/strong>
    As l\u00e2mpadas com balastros electr\u00f3nicos devem respeitar uma classe de temperatura m\u00e1xima de T4.<\/li>\n<\/ol>\n\n\n\n

    Este esquema t\u00e9cnico garante a conformidade com as normas de seguran\u00e7a para ambientes de alto risco, optimizando simultaneamente o desempenho e a durabilidade.<\/p>\n\n\n\n
