Condi\u00e7\u00f5es de trabalho<\/h2>\n
- \n
- A bucha \u00e9 adequada para uso em temperaturas ambientes de -40\u00b0C a 40\u00b0C. N\u00e3o \u00e9 adequada para uso em condi\u00e7\u00f5es que reduzam o desempenho do inv\u00f3lucro ou em caso de condensa\u00e7\u00e3o na superf\u00edcie da parte interna do inv\u00f3lucro.<\/li>\n
- Quando a temperatura ambiente da bucha estiver acima de +40\u00b0C, mas n\u00e3o exceder +60\u00b0C, recomenda-se que a carga de corrente nominal da bucha seja reduzida em 1,8\u00b0C para cada aumento de 1\u00b0C na temperatura ambiente.<\/li>\n
- Quando a bucha \u00e9 usada em uma temperatura ambiente superior a +40\u00b0C e de acordo com a temperatura de aquecimento m\u00e1xima permitida especificada em GB12944.1, Artigo 5.1, \u00e9 permitido que a corrente operacional seja sobrecarregada por um longo per\u00edodo de tempo, e recomenda-se que a corrente nominal seja reduzida em menos 0,5% para cada diminui\u00e7\u00e3o de 1\u00b0C na temperatura ambiente 0,5%, mas o aumento n\u00e3o deve ser superior a 20% da corrente nominal.<\/li>\n
- As buchas podem ser divididas em cinco tipos, de acordo com o local de uso: tipo comum para ambientes internos, tipo comum para ambientes externos e externos, tipo antipolui\u00e7\u00e3o para ambientes internos e externos, tipo plat\u00f4 para ambientes internos e externos, tipo antipolui\u00e7\u00e3o para plat\u00f4 para ambientes internos e externos.
\nO tipo geral interno \u00e9 geralmente adequado para locais de instala\u00e7\u00e3o at\u00e9 1000 m acima do n\u00edvel do mar, mas o local de instala\u00e7\u00e3o deve estar livre de sujeira evidente.
\nO tipo antipolui\u00e7\u00e3o para ambientes externos e internos \u00e9 adequado para \u00e1reas sujas em que o local de instala\u00e7\u00e3o n\u00e3o exceda 1.000 m acima do n\u00edvel do mar. Para inv\u00f3lucros de 35kV em \u00e1reas muito sujas, pode ser usada a bucha de parede capacitiva de papel-\u00f3leo de 63kV.
\nO tipo de plat\u00f4 externo e interno \u00e9 adequado para locais de instala\u00e7\u00e3o at\u00e9 3000 m acima do n\u00edvel do mar.
\nO tipo de plat\u00f4 externo e interno \u00e9 adequado para instala\u00e7\u00e3o em \u00e1reas sujas com altitude de 3000 m ou menos.<\/li>\n<\/ol>\n<\/p>\n
