Abstract

La presente invención se refiere a mejoras en interruptor de arco con rotación, caracterizadas porque comprende: un primer contacto eléctrico fijo; un electrodo de arco que tiene unos ejes axiales primero y segundo y que define un eje central longitudinal; forma de acoplar eléctricamente el electrodo de arco al contacto eléctrico fijo a través de la bobina de manera que se cree un campo maqgnético dentro del electrodo de arco durante el flujo de la corriente por la bobina; un segundo contacto eléctrico que tiene un brazo movible a voluntad a lo largo de un plano perpendicular al eje central longitudinal del electrodo, listo para unirse al contacto fijo, la sección del brazo es generalmente de forma de "L" presentando una primera porción angular que se extiende en una dirección paralela a la de dicho eje central longitudinal y un conductor que se extiende del segundo extremo axial del electrodo de arco hacia el primer extremo axial substancialmente a lo largo del eje longitudinal central, el conductor tiene un extremo axial interno separado de la primera porción angular de la sección del brazo, cuando esta es movida a una posición colineal con el eje central longitudinal; el contacto eléctrico fijo está dispuesto radialmente afuera del electrodo de arco adyacente al primer extremo del electrodo de arco en una posición tal, que la sección del brazo del contacto móvil se mueve hacia el eje central longitudinal del electrodo cuando se desconecta del primer contacto fijo, el conductor está construido y configurado para proveer un gradiente generalmente uniforme en el campo electrostático que rodea la primera porción angular d la sección del brazo cuando ésta sección es movida a una posición que intersecta al eje central longitudinal.The present invention refers to improvements in a rotating arc switch, characterized in that it comprises: a first fixed electrical contact; an arc electrode having first and second axial axes and defining a longitudinal central axis; way to electrically couple the arc electrode to the fixed electrical contact through the coil so that a magnetic field is created within the arc electrode during current flow through the coil; a second electrical contact having an arm movable at will along a plane perpendicular to the longitudinal central axis of the electrode, ready to join the fixed contact, the section of the arm is generally "L" shaped presenting a first angular portion that extending in a direction parallel to that of said longitudinal center axis and a conductor extending from the second axial end of the arc electrode towards the first axial end substantially along the central longitudinal axis, the conductor has a separate internal axial end of the first angular portion of the arm section, when it is moved to a collinear position with the longitudinal central axis; the fixed electrical contact is arranged radially outside the arc electrode adjacent to the first end of the arc electrode in such a position that the arm section of the movable contact moves towards the longitudinal center axis of the electrode when it is disconnected from the first fixed contact, the conductor is constructed and configured to provide a generally uniform gradient in the electrostatic field surrounding the first angular portion of the arm section when this section is moved to a position that intersects the longitudinal center axis.
