Abstract

Se describe un mecanismo para un brazo de contacto de un interruptor de circuito que permite limitar la corriente al reducir el tiempo de apertura. Un brazo de contacto se acopla con un mecanismo del brazo de contacto que incluye un portador acoplado con el primer par de eslabones. Un segundo par de eslabones se acopla con el primer par de eslabones. Un segundo portador acoplado con el segundo par de eslabones se acopla con el mecanismo del brazo de contacto con un mecanismo de interruptor de circuito principal a través de un ensamble de árbol intermedio. Luego de la presencia de una condición eléctrica no deseada, el mecanismo del brazo de contacto se mueve desde una posición cerrada a una posición abierta, lo que permite que el brazo de contacto sea abierto por soplado.
