L'Utilisation de la Tension de Ratio en une Seule Phase<\/h1>\n

\"undefined\"<\/a><\/p>\n

TransformersSingle-phase transformateurs sont couramment utilis\u00e9s dans de nombreuses applications \u00e9lectriques, soit d'intensifier ou d'abaisser la tension de l'alimentation. Le ratio de tension d'un transformateur se r\u00e9f\u00e8re au rapport de la tension d'entr\u00e9e \u00e0 la tension de sortie. Ce ratio est d\u00e9termin\u00e9 par le nombre de spires de l'enroulement primaire et le nombre de spires de l'enroulement secondaire.<\/p>\n

Le ratio de tension d'un transformateur monophas\u00e9 peut \u00eatre calcul\u00e9 en utilisant la formule suivante:<\/p>\n

Tension Ratio = (Nombre de tours dans l'enroulement secondaire) \/ (Nombre de tours dans l'enroulement primaire)<\/p>\n

Par exemple, si un transformateur de 1000 tours dans l'enroulement primaire et 200 tours de l'enroulement secondaire, la tension ratio serait de:<\/p>\n

Tension Ratio = 200 \/ 1000 = 0.2<\/p>\n

Cela signifie que la tension de sortie serait de 0,2 fois la tension d'entr\u00e9e.<\/p>\n

Transformateurs monophas\u00e9s sont couramment utilis\u00e9s dans les applications o\u00f9 la tension d'entr\u00e9e n'est pas adapt\u00e9 pour l'\u00e9quipement sous tension. Par exemple, si une pi\u00e8ce d'\u00e9quipement n\u00e9cessite une tension de 240 V, mais la puissance disponible de la tension d'alimentation est seulement 120V, un transformateur peut \u00eatre utilis\u00e9 pour intensifier la tension au niveau requis.<\/p>\n

En plus de l'intensification ou de marcher dans la tension, transformateurs monophas\u00e9s peut \u00e9galement \u00eatre utilis\u00e9 pour fournir une isolation entre l'entr\u00e9e et la sortie des circuits. Ceci est particuli\u00e8rement utile dans les applications o\u00f9 la tension d'entr\u00e9e peut \u00eatre bruyant ou \u00eatre soumis \u00e0 des interf\u00e9rences.<\/p>\n

En r\u00e9sum\u00e9<\/strong><\/h2>\n

Le ratio de tension est un facteur important \u00e0 consid\u00e9rer lors de la s\u00e9lection et l'utilisation de transformateurs monophas\u00e9s. Par la compr\u00e9hension de la tension de ratio et le nombre de tours dans les enroulements primaire et secondaire, il est possible de d\u00e9terminer le transformateur pour une application particuli\u00e8re.<\/p>\n
