El sistema cinemático 1 incluye un mecanismo de actuación 5 para el disyuntor operado mediante corriente residual, mostrado en las Figs. 3-10, y un mecanismo 7 de circuito de prueba, mostrado en las Figs. 11-16.The kinematic system 1 includes a mechanism of actuation 5 for the circuit breaker operated by residual current, shown in Figs. 3-10, and a mechanism 7 of test circuit, shown in Figs. 11-16.
El mecanismo de actuación incluye unos medios de actuación que están constituidos por ejemplo por una palanca 9 convencional que está montada de manera pivotante en el cuerpo 3 y está conectada a una palanca de actuación 11 mediante un travesaño 13 en forma de U. La palanca de actuación 11 está conectada al sistema cinemático del disyuntor automático, mostrado esquemáticamente en la Fig. 1. El travesaño 13 está conectado a una palanca de actuación 15 que está asociada operativamente con un resorte de reposición y con un resorte de actuación 19 sobre un pivote 21 común.The mechanism of action includes means of action that are constituted for example by a lever 9 conventional that is pivotally mounted on body 3 and is connected to an actuation lever 11 by means of a crossbar 13 U-shaped. Actuating lever 11 is connected to the automatic circuit breaker kinematic system, shown schematically in Fig. 1. The crossbar 13 is connected to a actuation lever 15 which is operatively associated with a replacement spring and with an actuation spring 19 on a common pivot 21.
Un miembro 23 en forma de champiñón del relé actúa sobre una palanca de reposición 25 que está a su vez asociada cinemáticamente con un gancho 27 que está soportado por un segundo pivote 29 común y provisto de un resorte de retorno 47. Una palanca de aplicación 31, retenida por el gancho 27, es adecuada para actuar sobre la parte trasera de la palanca de tracción 33. La palanca de aplicación 31 está conectada a un indicador 35 que está montado de manera pivotante en la palanca 9 y está provisto de un resorte de retorno 49.A mushroom-shaped member 23 of the relay acts on a reset lever 25 which is in turn associated kinematically with a hook 27 that is supported for a second pivot 29 common and provided with a return spring 47. A lever of application 31, retained by hook 27, is suitable to act on the rear of the traction lever 33. The lever application 31 is connected to an indicator 35 which is mounted from pivotally in the lever 9 and is provided with a spring of return 49.
El mecanismo 7 del circuito de prueba se muestra con más detalle en las Figs. 11-16 e incluye un botón de prueba 37 que es adecuado para actuar sobre una banda de prueba 39 que actúa sobre un resorte de contacto 41. El contacto fijo 43 está conectado al pivote 21 por medio del resorte de actuación 19 y a una resistencia 45 por medio del resorte de contacto 41. La resistencia 45 está a su vez conectada al terminal.The mechanism 7 of the test circuit is shown in more detail in Figs. 11-16 and includes a test button 37 which is suitable for acting on a band of test 39 acting on a contact spring 41. The contact fixed 43 is connected to pivot 21 by means of the spring of actuation 19 and a resistance 45 by means of the spring of contact 41. The resistor 45 is in turn connected to the terminal.
La operación del sistema cinemático es como sigue.The operation of the kinematic system is like follow.
Haciendo girar la palanca 9, se mueve el travesaño 13 y gira la palanca de actuación 11, la cual actúa sobre el sistema cinemático del disyuntor automático. El travesaño 13 está también acoplado rígidamente a la palanca de actuación 15, la cual en la acción de cierre gira y carga el resorte de reposición 17 y el resorte de actuación 19. El resorte de reposición 17, cargándose, libera la palanca de reposición 25, la cual puede así ser empujada por el miembro en forma de champiñón 23 del relé en caso de activación.By rotating lever 9, the crossbar 13 and rotate the actuation lever 11, which acts on the kinematic system of the automatic circuit breaker. The crossbar 13 is also rigidly coupled to the actuation lever 15, which in the closing action, rotate and load the reset spring 17 and the actuation spring 19. The replacement spring 17, charging, releases the reset lever 25, which can thus be pushed by the mushroom-shaped member 23 of the relay in case of activation.
En caso de activación, la parte en forma de champiñón del relé empuja a la palanca de reposición 25, la cual, moviéndose hacia abajo, desplaza al gancho 27. De esta forma, la palanca de aplicación 31 es liberada y gira; golpeando la parte trasera de la palanca de tracción 33, la palanca de aplicación 31 permite la liberación del sistema cinemático del disyuntor automático. La palanca de aplicación 31 también desacopla el indicador 35, que en la posición cerrada estaba acoplado rígidamente a su parte trasera. La reposición ocurre inmediatamente después de la activación: cuando la palanca 9 vuelve, el resorte de actuación 19 hace girar la palanca de actuación 15 en sentido opuesto con respecto a la rotación de cierre. De esta forma, la palanca de actuación repone la palanca de aplicación 31 en virtud de su acoplamiento físico, volviendo a situar su extremo inferior en el asiento del gancho 27, mientras que el resorte de reposición 17 repone la palanca de reposición 25, reponiendo el relé con una fuerza que está relacionada con la velocidad de retorno de la palanca 9 y está por tanto calibrada. Se ha de observar que durante la reposición el indicador 35 está todavía activo y se desactiva sólo tras el primer cierre.In case of activation, the part in the form of relay mushroom pushes the reset lever 25, which, moving down, it moves to hook 27. In this way, the application lever 31 is released and rotates; hitting the part rear of traction lever 33, application lever 31 allows the release of the kinematic system from the circuit breaker automatic. The application lever 31 also decouples the indicator 35, which in the closed position was rigidly coupled to its rear. Replenishment occurs immediately after activation: when lever 9 returns, the actuation spring 19 rotates the actuation lever 15 in the opposite direction with regarding the closing rotation. In this way, the lever of actuation replenishes the application lever 31 by virtue of its physical coupling, repositioning its lower end in the hook seat 27 while the replacement spring 17 reset the reset lever 25, resetting the relay with a force that is related to the speed of return of the lever 9 and is therefore calibrated. It should be noted that during reset indicator 35 is still active and is deactivated only after the first closure.
La operación del circuito de prueba conlleva la simulación de una corriente residual con el fin de comprobar la operación del relé y del disyuntor. Cuando se levanta el botón de prueba 37, se abre el circuito y el resorte de contacto 41 en realidad no toca el pivote 21. Accionando el botón de prueba en el sentido indicado por las flechas en las figuras, el resorte de contacto 41 se baja, cerrando el circuito. Se ha de observar que cuando el sistema cinemático diferencial se ha disparado o activado, el circuito de prueba no debe ser usable, de otro modo la resistencia 45 se quemaría. La deshabilitación del circuito de prueba se logra de dos formas: bien levantando el resorte de contacto 41 por medio de la palanca de aplicación 31, la cual mediante rotación eleva la parte inferior del resorte de contacto 41, o en virtud del aislamiento del pivote 21 obtenido mediante la rotación del asiento del pivote en la palanca de actuación 15, cuando la palanca 9 está en la posición abierta.The operation of the test circuit involves the simulation of a residual current in order to check the Relay and circuit breaker operation. When the button is raised test 37, the circuit and the contact spring 41 is opened in actually does not touch pivot 21. By pressing the test button on the direction indicated by the arrows in the figures, the spring of contact 41 is lowered, closing the circuit. It should be noted that when the differential kinematic system has tripped or activated, the test circuit must not be usable, otherwise the resistance 45 would burn. Disabling the circuit of test is achieved in two ways: well by raising the spring of contact 41 by means of the application lever 31, which by rotation it raises the lower part of the contact spring 41, or by virtue of the isolation of pivot 21 obtained by the pivot seat rotation on actuation lever 15, when lever 9 is in the open position.
En la práctica se ha encontrado que la invención logra el objetivo y objetos buscados.In practice it has been found that the invention achieve the objective and objects sought.
