Abstract

Sistema de termopar magnético para la seguridad positiva de la alimentación de gas a través de quemadores o similares, concretamente de control de seguridad positiva para dispositivos domésticos de cocción, cuyo sistema está dotado de: al menos un quemador de gas, cuyo quemador de gas está conectado a una fuente de alimentación de gas a través de medios de regulación de la llama y a través de una válvula de seguridad dirigida por un sensor para la indicación de la presencia de llama formado por un termopar, presentando dicha válvula de seguridad una condición de apertura, en la que la fuente de alimentación alimenta dicho quemador, y una condición de cierre, en la que se interrumpe el paso del gas y el termopar genera en presencia de llama una señal eléctrica que constituye la señal de mando para el paso de la condición de apertura a la condición de cierre, y viceversa, de dicha válvula de seguridad, mientras que está previsto otro generador y alimentador de la señal de mando de dicha válvula de seguridad para la alimentación temporal y en alternativa a dicha válvula de seguridad durante la fase de encendido de la llama y de calentamiento del termopar a la temperatura de generación de la señal de mando. Conforme a la invención, el generador y alimentador de la señal está dotado de limitadores de potencia de la señal generada y una unidad de desactivación automática en caso de sobrecarga del alimentador durante un tiempo preestablecido, siendo la potencia necesaria para la señal de mando de la válvula de seguridad superior a la determinada por los limitadores.
