<\/p>\nEn pocas palabras, un fallo de arco es electricidad \u201csaltando\u201d o \u201cchispeando\u201d. En condiciones normales, la corriente el\u00e9ctrica fluye obedientemente por los cables. Pero cuando el aislamiento de los cables envejece o se da\u00f1a, o cuando las conexiones se aflojan, la corriente toma un camino alternativo: salta a trav\u00e9s de los espacios de aire, creando una chispa brillante. Esto es un fallo de arco.<\/p>\n
<\/p>\n
Los fallos de arco generan temperaturas extremadamente altas, con temperaturas en el n\u00facleo que superan los 3.000 \u00b0C, \u00a1m\u00e1s que la soldadura! Pueden inflamar instant\u00e1neamente los materiales combustibles circundantes, como madera, tejidos y pl\u00e1sticos. Las estad\u00edsticas muestran que una parte significativa de los incendios el\u00e9ctricos est\u00e1n causados por fallos de arco. Lo que es a\u00fan m\u00e1s aterrador es que los arcos en serie (\u201cconexiones sueltas\u201d en el circuito) transportan corrientes muy peque\u00f1as que los disyuntores est\u00e1ndar no pueden detectar, aunque el riesgo de incendio es muy real.<\/p>\n
El AFDD (dispositivo de detecci\u00f3n de fallos de arco) act\u00faa como un \u201cojo de fuego\u201d para sus circuitos el\u00e9ctricos. Contiene sensores de alta sensibilidad que supervisan las formas de onda de la corriente en tiempo real. Las formas de onda de corriente normales son suaves y regulares, mientras que la corriente de arco muestra caracter\u00edsticas de mutaci\u00f3n en \u201cdiente de sierra\u201d. El AFDD utiliza algoritmos inteligentes para analizar estas caracter\u00edsticas de la forma de onda, identificando los arcos peligrosos en milisegundos y cortando la corriente inmediatamente.<\/p>\n
El AFDD puede detectar y proteger eficazmente contra ambos tipos de fallos de arco.<\/p>\n
Los disyuntores y dispositivos diferenciales tradicionales s\u00f3lo protegen contra sobrecargas, cortocircuitos y fugas, pero no contra los incendios por arco el\u00e9ctrico. El AFDD cubre espec\u00edficamente esta laguna de seguridad. Es especialmente adecuado para casas antiguas, estructuras de madera y hogares con electrodom\u00e9sticos de alta potencia. Instalar un AFDD es como a\u00f1adir un \u201ccortafuegos\u201d a su sistema el\u00e9ctrico, lo que proporciona mayor tranquilidad a su familia.<\/p>","protected":false},"excerpt":{"rendered":"
