Title
(EN) ELECTRIC HEATING SYSTEM (ITS VARIANTS)
(FR) SYSTÈME DE CHAUFFAGE ÉLECTRIQUE (SES VARIANTES)
Abstract
(EN)
The claimed invention refers to electric heating systems, powered by AC mains with a frequency of 50-1000 Hz that use resistance heating elements as heat-generating elements. In the claimed system the electric shock protection device, executed on the basis of the safe dividing transformer, is additionally equipped with the generator, series-connected between AC mains circuit and the safe dividing transformer, at that the operational frequency of the generator is selected in such a manner that the frequency spectrum of the acoustic radiation signal generated by the safe dividing transformer, is out of hearing by ears of a man and/or animal. The claimed invention allows to produce modern electrically safe energy-efficient noiseless heating systems of enhanced comfort.
(FR)
La présente invention concerne des systèmes de chauffage électrique, alimentés par un réseau de secteur alternatif ayant une fréquence de 50 à 1 000 Hz, qui utilisent des éléments de chauffage par résistance en tant qu'éléments de génération de chaleur. Dans le système selon l'invention, un dispositif de protection contre les chocs électriques, exécuté sur la base d'un transformateur de division de sécurité, est en outre équipé d'un générateur, connecté en série entre un circuit de secteur alternatif et le transformateur de division de sécurité, et la fréquence de fonctionnement du générateur est sélectionnée de telle sorte que le spectre de fréquence du signal de rayonnement acoustique généré par le transformateur de division de sécurité n'est pas audible par les oreilles d'un homme et/ou d'un animal. La présente invention permet de produire des systèmes de chauffage sans bruit à faible consommation d'énergie, sûrs sur le plan électrique, modernes et à confort amélioré.
