VB4P<\/strong> O disjuntor a v\u00e1cuo de m\u00e9dia tens\u00e3o para ambientes internos \u00e9 aplic\u00e1vel ao sistema de energia CA trif\u00e1sico com tens\u00e3o nominal de at\u00e9 12~24kV e frequ\u00eancia de 50\/60Hz, amplamente utilizado em muitos campos, como usina de energia, subesta\u00e7\u00e3o de transformadores, ind\u00fastria qu\u00edmica de petr\u00f3leo, metalurgia, ind\u00fastria manufatureira, aeroporto, \u00e1rea residencial, etc, Para controlar e proteger o equipamento el\u00e9trico, especialmente para ocasi\u00f5es em que \u00e9 necess\u00e1ria uma opera\u00e7\u00e3o pouco frequente com corrente nominal ou corrente de curto-circuito com v\u00e1rias quebras, pode ser montado no painel de distribui\u00e7\u00e3o isolante de ar interno, como o tipo KYN28 ou AMS, s\u00e9rie ABB tipo ZS1, etc. Esse disjuntor est\u00e1 de acordo com as normas IEC60694.<\/p>\n

Esse disjuntor \u00e9 fabricado com a madura tecnologia APG. A aplica\u00e7\u00e3o do buffer de terminal VB4P garante que o terminal interno seja cada vez mais confi\u00e1vel em qualquer ambiente de opera\u00e7\u00e3o. O VB4P pode atender totalmente aos requisitos de GB, DL, IEC, DIN, VDE, bem como aos padr\u00f5es de outros pa\u00edses industrializados avan\u00e7ados.<\/p>\n

Ambiente de servi\u00e7o<\/h2>\n

a) Temperatura do ar: Temperatura m\u00e1xima: +40\u2103; temperatura m\u00ednima: -25\u2103<\/p>\n

b) Umidade: Umidade m\u00e9dia mensal 95%; umidade m\u00e9dia di\u00e1ria 90%.<\/p>\n

c) Altitude acima do n\u00edvel do mar: Altitude m\u00e1xima de instala\u00e7\u00e3o: 2500 m<\/p>\n

d) O ar ambiente n\u00e3o parece estar polu\u00eddo por gases corrosivos e inflam\u00e1veis, vapor etc.<\/p>\n

e) Sem tremores violentos frequentes<\/p>\n

    \n
  • Alta confiabilidade<\/strong><\/li>\n<\/ul>\n

    Em compara\u00e7\u00e3o com o poste montado tradicional, o n\u00famero de pe\u00e7as, a superf\u00edcie de conex\u00e3o do condutor e os fixadores de conex\u00e3o usados no poste embutido podem ser reduzidos em uma grande margem, de modo a simplificar o procedimento de montagem do circuito principal, diminuir a resist\u00eancia do circuito e aumentar a confiabilidade da conex\u00e3o do circuito principal.<\/p>\n

      \n
    • Propriedade de isolamento est\u00e1vel<\/strong><\/li>\n<\/ul>\n

      Depois que o interruptor a v\u00e1cuo \u00e9 incorporado ao material s\u00f3lido de resina ep\u00f3xi, o ambiente externo do poste pode ter o menor efeito sobre o interruptor a v\u00e1cuo. Com a capacidade de isolamento externo, o poste n\u00e3o pode ser afetado por poeira, umidade, pequenos animais, condensa\u00e7\u00e3o e polui\u00e7\u00e3o. Ele pode atender completamente ao requisito de dist\u00e2ncia de fuga da regi\u00e3o polu\u00edda de grau II especificada na norma GB\/DL.<\/p>\n

        \n
      • Estrutura da empresa<\/strong><\/li>\n<\/ul>\n

        Forne\u00e7a prote\u00e7\u00e3o suficiente para o interruptor a v\u00e1cuo, de modo que ele n\u00e3o sofra colis\u00e3o mec\u00e2nica acidental no processo de montagem ou transporte.<\/p>\n

          \n
        • Miniaturiza\u00e7\u00e3o<\/strong><\/li>\n<\/ul>\n

          Adote a resina ep\u00f3xi como meio de isolamento para reduzir a dist\u00e2ncia entre fases e diminuir o volume do disjuntor a v\u00e1cuo e do gabinete de distribui\u00e7\u00e3o correspondente.<\/p>\n

            \n
          • Manuten\u00e7\u00e3o gratuita<\/strong><\/li>\n<\/ul>\n

            Como todo o polo \u00e9 colocado em um componente integral, o interruptor a v\u00e1cuo pode obter prote\u00e7\u00e3o suficiente. A manuten\u00e7\u00e3o gratuita do interruptor a v\u00e1cuo pode proporcionar a condi\u00e7\u00e3o para a manuten\u00e7\u00e3o gratuita do disjuntor.<\/p>\n
