Este aparato de corte consta de un mecanismo de arrastre que puede ser de cualquier tipo conocido que conste de un arbol de los polos. Puede tratarse, por ejemplo, de un mecanismo del tipo descrito en el documento EP-A-0 222 645, provisto de un subconjunto de armado y de cierre que consta de un muelle de cierre, y de un subconjunto de apertura que consta de un muelle de apertura. En esta realizacion de la invencion ilustrada en la figura 1, el arbol de los polos 2 que permite el arrastre de los contactos hacia la posicion de apertura o de cierre, tambien se utiliza para realizar el rearmado del muelle 1 de cierre de los contactos, al final de la maniobra de cierre de los contactos.This cutting apparatus consists of a drive mechanism that can be of any known type consisting of a pole tree. It can be, for example, a mechanism of the type described in EP-A-0 222 645, provided with a subassembly assembly and closure consisting of a closing spring, and an opening subset consisting of a opening dock In this embodiment of the invention illustrated in Figure 1, the pole tree 2 that allows the contacts to be dragged to the opening or closing position is also used to reassemble the spring 1 for closing the contacts, at the end of the closing maneuver of the contacts.
En esta realizacion particular, el final de la operacion de cierre de los contactos provoca el rearmado de un dispositivo con acumulacion de energfa, destinado a permitir las maniobras de los ciclos rapidos de apertura-cierre espedficos de los disyuntores de proteccion de media tension.In this particular embodiment, the end of the closing operation of the contacts causes the reassembly of a device with energy accumulation, intended to allow the maneuvers of the rapid opening-closing cycles specific to the medium voltage protection circuit breakers.
Este arbol de los polos 2, por uno de sus extremos, esta destinado a que lo arrastre el dispositivo de accionamiento del aparato, mientras que su extremo opuesto consta de una rueda 3 denominada primera destinada a cooperar con el dispositivo M de motorizacion, estando este arbol ademas unido mecanicamente, entre estos dos extremos, al muelle 1 de cierre citado con anterioridad.This tree of the poles 2, by one of its ends, is intended to be dragged by the device driving device, while its opposite end consists of a wheel 3 called first intended to cooperate with the motorization device M, this being tree also mechanically joined, between these two ends, to the closing spring 1 mentioned above.
Esta rueda 3 denominada primera esta destinada a que la arrastre en rotacion un pinon 4 denominado primero que pertenece al dispositivo M de motorizacion por medio de un dispositivo 5 intermedio. Este dispositivo 5 intermedio consta de una rueda 6 denominada secundaria y de un pinon 7 denominado secundario, estando esta rueda 6 secundaria destinada a que la arrastre el pinon 4 del dispositivo M de motorizacion, mientras que el pinon 7 denominado secundario solidario en rotacion con la rueda 6 denominada segunda, coopera con la rueda 3 denominada primera, de manera que en la posicion embragada, el dispositivo M de motorizacion arrastre en rotacion a la rueda 3 denominada primera y, por lo tanto, al arbol 2 de accionamiento por medio de la rueda 6 denominada segunda y del pinon 7 denominado segundo.This wheel 3 called first is intended to be rotated by a pin 4 called first belonging to the motorization device M by means of an intermediate device 5. This intermediate device 5 consists of a wheel 6 called secondary and a pin 7 called secondary, this secondary wheel 6 being intended to be driven by pin 4 of the motorization device M, while pin 7 called a secondary solidarity in rotation with the wheel 6 called second, cooperates with wheel 3 called first, so that in the clutch position, the motorization device M rotates in rotation to the wheel 3 called first and, therefore, to the drive shaft 2 by means of the wheel 6 called second and pin 7 called second.
Segun la invencion, y tal como se ilustra en la figura 2, la rueda 3 denominada primera consta, en el extremo de una parte de arbol 12 solidaria con la rueda y coaxial con dicha rueda, un sector 8 de disco anular que consta de una abertura 8a, destinado a cooperar con un cono 9 de embrague previsto en la rueda 6 denominada segunda. Este cono de embrague esta situado en la cara de la rueda 6 opuesta a la que se encuentra enfrentada a la rueda 3 denominada primera, tal como se puede ver mejor en la figura 6.According to the invention, and as illustrated in Figure 2, the wheel 3 called first consists, at the end of a part of shaft 12 integral with the wheel and coaxial with said wheel, an annular disk sector 8 consisting of a opening 8a, intended to cooperate with a clutch cone 9 provided in the wheel 6 called second. This clutch cone is located on the face of the wheel 6 opposite to the one facing the wheel 3 called first, as can be best seen in Figure 6.
Un muelle 11 de compresion esta apoyado por uno de sus extremos sobre una cara de un soporte fijo del aparato, y por un extremo opuesto sobre una cara del pinon 7 asociado a la rueda 6 secundaria, estando dicho muelle montado en el interior de dicho pinon, tal como se puede ver mejor en la figura 8.A compression spring 11 is supported by one of its ends on a face of a fixed support of the apparatus, and by an opposite end on a face of pinon 7 associated with the secondary wheel 6, said spring being mounted inside said pinon , as best seen in Figure 8.
Segun la realizacion de la invencion ilustrada en las figuras, la rueda 6 denominada segunda y el pinon 7 denominado segundo forman un conjunto monobloque apto para deslizarse axialmente entre una primera posicion en la que la rueda 6 denominada segunda del dispositivo 5 intermedio esta encajada con el pinon 4 denominado primero del dispositivo M de motorizacion y una segunda posicion en la que estos dos elementos se desencajan uno con respecto al otro.According to the embodiment of the invention illustrated in the figures, the wheel 6 called the second and the pin 7 called the second form a monobloc assembly capable of axially sliding between a first position in which the wheel 6 called the second of the intermediate device 5 is fitted with the pin 4 called first of the motorization device M and a second position in which these two elements are disengaged from each other.
Segun una realizacion particular de la invencion, la longitud de la parte 8a vada del disco 8 perforado corresponde a la carrera de cierre del dispositivo de accionamiento.According to a particular embodiment of the invention, the length of the blank part 8a of the perforated disc 8 corresponds to the closing stroke of the drive device.
El funcionamiento del dispositivo de desembragado segun la realizacion ilustrada se va a describir a continuacion en referencia a las figuras 4 a 11.The operation of the disengagement device according to the illustrated embodiment will be described below in reference to Figures 4 to 11.
En las figuras 4, 5 y 6, el dispositivo esta al final del armado del muelle de cierre. En esta posicion, el sector 8 de disco de la rueda 3 coopera con la protuberancia 9 para empujar a la rueda 6 secundaria y a su pinon 7 asociado hacia el muelle de desembragado (es decir hacia la parte superior de la figura), posicion en la que a la rueda 6 secundaria la arrastra el pinon 4 del dispositivo de motorizacion. Este desplazamiento de la rueda secundaria se realiza en contra del muelle 11 de compresion cuya funcion es empujar a la rueda 6 secundaria hacia el lado opuesto a la rueda 3 denominada primera (es decir hacia la parte inferior de la figura 5). Esta posicion tambien se ilustra en la figura 11.In figures 4, 5 and 6, the device is at the end of the assembly of the closing spring. In this position, the disc sector 8 of the wheel 3 cooperates with the protrusion 9 to push the secondary wheel 6 and its associated pinon 7 towards the disengaged spring (ie towards the top of the figure), position in the that pin 4 of the motorization device is dragged to the secondary wheel 6. This displacement of the secondary wheel is carried out against the compression spring 11 whose function is to push the secondary wheel 6 towards the opposite side of the wheel 3 called first (ie towards the bottom of Figure 5). This position is also illustrated in Figure 11.
En las figuras 7 a 9, despues de un desplazamiento en el sentido de las agujas del reloj del arbol 2 de accionamiento, y de este modo de la rueda 3 denominada primera, se lleva al dispositivo de accionamiento a una posicion armada lista para cerrar. En esta posicion, a la rueda 6 secundaria ya no lo empuja hacia arriba el sector 8 de disco ya que este se oculta y la protuberancia de la rueda 6 denominada segunda se ha llevado a la abertura 8a del disco, utilizando el muelle que actua sobre la rueda secundaria. Esta posicion tambien se ilustra en la figura 10.In figures 7 to 9, after a clockwise movement of the drive shaft 2, and thus of the wheel 3 called first, the drive device is taken to an armed position ready to close. In this position, the secondary wheel 6 is no longer pushed up by the disk sector 8 since it is hidden and the protrusion of the second called wheel 6 has been taken to the opening 8a of the disk, using the spring acting on the secondary wheel This position is also illustrated in Figure 10.
Durante el movimiento de cierre de los contactos del aparato, la posicion desembragada se mantiene durante todo el periodo del cierre debido a que el sector 8 anular de la primera rueda 3 ya no coopera con el cono 9 de embrague durante todo este periodo, sin imponer por lo tanto un embragado, correspondiendo la longitud de la parte 8a vada del disco perforado sustancialmente a la longitud de la carrera de cierre.During the closing movement of the contacts of the device, the disengaged position is maintained throughout the closing period because the annular sector 8 of the first wheel 3 no longer cooperates with the clutch cone 9 during this entire period, without imposing therefore a clutch, the length of part 8a vada of the perforated disc corresponding substantially to the length of the closing stroke.

Hay que senalar que segun otra realizacion no ilustrada, la rueda denominada segunda podra estar unida mecanicamente a su pinon asociado por medio de un dispositivo con pestana que permite que dicha rueda se desplace con respecto a su pinon asociado, la cual al desplazarse, se desolidariza de este, interrumpiendo de este modo la union mecanica entre la rueda denominada primera y el pinon denominado primero. Este dispositivo con pestana consta de manera conocida en sf misma de un diente de arrastre dentro de un manguito de embrague con garras.It should be noted that according to another embodiment not illustrated, the so-called second wheel could be mechanically attached to its associated pinon by means of a flanged device that allows said wheel to move with respect to its associated pinon, which, when moving, will be dismantled of this, thus interrupting the mechanical union between the wheel called first and the pinon called first. This device with a flange consists in a manner known per se of a drive tooth within a clutch sleeve with claws.
En este caso, el muelle de retorno actuara directamente sobre la rueda 6 denominada segunda, pasando a traves del pinon 7. Estara siempre guiado por la escotadura de este pinon 7 que permanecera en la posicion engranada sobre la rueda 3 denominada primera. Es suficiente con prever en este pinon 7 un resalte que lo mantenga contra la rueda 3.In this case, the return spring will act directly on the wheel 6 called second, passing through pin 7. It will always be guided by the recess of this pin 7 which will remain in the position engaged on the wheel 3 called first. It is enough to provide in this pinon 7 a projection that keeps it against the wheel 3.
Por lo tanto, se ha realizado por medio de la invencion un dispositivo de mantenimiento del desembragado durante el cierre del aparato lo que permite suprimir los golpes que reciben los pinones de desembragado durante el cierre del aparato, por ejemplo los chasquidos, solicitaciones por golpes de las espigas, inercia, etc., como era el caso para una motorizacion con un tren de engranajes siempre en contacto con el arbol principal del dispositivo de accionamiento.Therefore, a disengagement maintenance device has been carried out by means of the invention during the closure of the apparatus, which makes it possible to suppress the blows received by the disengagement pins during the closure of the apparatus, for example clicks, requests for blows of the pins, inertia, etc., as was the case for a motorization with a gear train always in contact with the main shaft of the drive device.
La presente invencion permite, por lo tanto, mejorar el comportamiento en resistencia mecanica de las piezas del dispositivo de desembragado de la motorizacion.The present invention therefore allows to improve the mechanical resistance behavior of the parts of the motorized disengagement device.
Este dispositivo permite desembragar la motorizacion al final del armado del accionamiento para no danarlo de forma prematura y tambien desembragar la motorizacion durante el cierre del disyuntor, para no arrastrar el tren de engranajes de la motorizacion y deteriorarlo y para no perturbar el cierre del accionamiento. Este dispositivo utiliza la propiedad que los engranajes con perfil de dientes rectos en envolventes de cfrculo no transmiten ninguna fuerza axial.This device allows to disengage the motorization at the end of the assembly of the drive so as not to damage it prematurely and also to disengage the motorization during the closing of the circuit breaker, so as not to drag the gear train of the motorization and deteriorate it and not to disturb the closing of the drive. This device uses the property that gears with straight tooth profile in circle envelopes do not transmit any axial force.
Este dispositivo no utiliza la inercia y la energfa cinetica de los engranajes de la motorizacion que produce la velocidad de rotacion del arbol y la relacion de reduccion.This device does not use the inertia and the kinetic energy of the gears of the motorization that produces the rotation speed of the tree and the reduction ratio.
Hay que senalar entre las demas ventajas de la invencion, el hecho de que el muelle esta poco comprimido en la posicion desembragada, cuando el aparato esta en la posicion cerrada, al estar el dispositivo de accionamiento en la posicion armada, lo que corresponde a la posicion normal para un aparato de accionamiento en la red, de lo que se derivan un menor riesgo de desgaste del muelle.It is necessary to point out among the other advantages of the invention, the fact that the spring is little compressed in the disengaged position, when the apparatus is in the closed position, since the drive device is in the armed position, which corresponds to the normal position for a drive device in the network, resulting in a lower risk of spring wear.
Por otra parte, si a pesar de todo el muelle ya no funcionara correctamente, el dispositivo permanecena embragado despues de un desembragado, y hay que senalar que es mas facil pasar bajo el efecto del muelle de la posicion embragada a la aposicion desembragada que a la inversa. Por ultimo, hay que senalar que se realiza mejor el guiado del muelle de retorno puesto que este ultimo se encuentra naturalmente guiado dentro del pinon 7.On the other hand, if in spite of the whole spring it is no longer working properly, the device remains clutched after a disengagement, and it should be noted that it is easier to pass under the effect of the spring of the position cloned to the disengaged position than to the inverse Finally, it should be noted that the return spring guidance is best performed since the latter is naturally guided within pin 7.
Por supuesto, la invencion no esta limitada a la forma de realizacion descrita e ilustrada que solo se ha dado a tftulo de ejemplo.Of course, the invention is not limited to the described and illustrated embodiment that has only been given by way of example.
