\u00bfCu\u00e1les Son los Especiales Requisitos de Protecci\u00f3n para la Prueba de Explosiones de Transformadores?<\/b><\/h1>\n

En industrias de alto riesgo, tales como la petroqu\u00edmica, la miner\u00eda y la fabricaci\u00f3n de productos farmac\u00e9uticos, a prueba de explosiones de transformadores de n\u00facleo de equipamiento para garantizar la seguridad de suministro de energ\u00eda. Estos ambientes especiales son a menudo cargados con gases inflamables, vapores o polvo en el que incluso una peque\u00f1a chispa el\u00e9ctrica puede provocar una explosi\u00f3n catastr\u00f3fica. Por lo tanto, a prueba de explosi\u00f3n, los transformadores deben cumplir con los m\u00faltiples estrictos requisitos de protecci\u00f3n muy superiores a los de los productos est\u00e1ndar para construir una s\u00f3lida barrera de seguridad.<\/p>\n

1.1 Requisitos B\u00e1sicos:\u00a0<\/strong><\/h4>\n

En atm\u00f3sferas explosivas, la entrada de polvo externa o de agua en el equipo puede conducir a dos riesgos importantes:<\/p>\n

(1) La Acumulaci\u00f3n De Polvo & Sobrecalentamiento:\u00a0<\/strong><\/h6>\n

Conductora de polvo de sedimentaci\u00f3n en los devanados o partes conductoras pueden crear anormal caminos de corriente, causando un sobrecalentamiento localizado debido al calentamiento de Joule efecto. Este aumento de la temperatura podr\u00eda superar el M\u00ednimo de la Temperatura de Ignici\u00f3n (MIT) de polvo explosivo.<\/p>\n

(2) La Humedad Inducida Por Cortocircuitos \/ Chispas:\u00a0<\/strong><\/h6>\n

El agua o la humedad alta degrada el rendimiento de aislamiento, que conduce a la fase-a-fase de cortocircuitos o fallas a tierra, la generaci\u00f3n de chispas con la energ\u00eda suficiente para producir la ignici\u00f3n de una mezcla explosiva.<\/p>\n
