La presente invencion se refiere a los aparatos de corte de corriente electrica de baja tension en general, y en particular los aparatos de corte de corriente electricos instalados en los particulares y habitualmente denominados "disyuntores de acoplamiento".The present invention relates to low voltage electric current cutting devices in general, and in particular electric power cutting devices installed in the private and usually called "coupling circuit breakers".
Estado de la tecnica anteriorState of the prior art
Se conoce el documento FR 2 295 553 que describe un aparato de corte de la corriente electrica, estando dicho aparato alojado en una carcasa aislante y constando al menos de un conjunto unipolar y de un mecanismo de control, constando dicho conjunto unipolar de un zocalo aislante que soporta unos tabiques que delimitan una camara de corte destinada a asegurar el confinamiento del corte, estando dicha camara cerrada, con la excepcion de una abertura lateral de escape habilitada en un tabique, por una tapa que se aplica sobre dicha camara de corte, conteniendo dicha camara un contacto fijo, un contacto movil soportado por un portacontactos movil, un dispositivo de extincion de arco, pudiendo dicho mecanismo de control llevarse manual o automaticamente a una posicion de apertura de los contactos mediante una barra de disparo denominada primera, constando dicho mecanismo de control de un arbol apto para accionar dicho portacontactos.Document FR 2 295 553 is known which describes an apparatus for cutting the electric current, said apparatus being housed in an insulating housing and comprising at least one unipolar assembly and a control mechanism, said unipolar assembly consisting of an insulating socket. which supports partitions that delimit a cutting chamber intended to ensure the confinement of the cut, said chamber being closed, with the exception of a side exhaust opening enabled in a partition, by a cover that is applied on said cutting chamber, containing said camera a fixed contact, a mobile contact supported by a mobile contact holder, an arc extinguishing device, said control mechanism being able to be manually or automatically brought to a position of opening of the contacts by means of a firing bar called first, said mechanism comprising of control of a tree suitable for operating said contact holder.
En este documento, la parte de la carcasa destinada a realizar el confinamiento del corte consta de dos piezas de bombilla que referencian los contactos fijos y los disparadores magnetotermicos. Estas dos piezas de bombilla estan ellas mismas referenciadas en el zocalo que sirve igualmente de cara externa. Ademas, este zocalo sirve de referencia para otras funcionas mecanicas, es decir el mecanismo denominado interruptor que permite la maniobra manual del aparato y el soporte de contacto movil. De este modo, esta arquitectura impone a algunas piezas ciertas tipologfas de funciones, es decir, para las bombillas, las funciones de referenciacion mecanica y de confinamiento del corte, y para el zocalo, las funciones de referenciacion mecanica y de cara externa.In this document, the part of the housing destined to carry out the confinement of the cut consists of two pieces of bulb that reference the fixed contacts and the magnetothermal triggers. These two pieces of bulb are themselves referenced in the socket that also serves as an external face. In addition, this socket serves as a reference for other mechanical functions, that is, the mechanism called a switch that allows the manual maneuver of the device and the mobile contact support. In this way, this architecture imposes certain types of functions on some pieces, that is, for light bulbs, the functions of mechanical reference and confinement of the cut, and for the socket, the functions of mechanical reference and external face.
El hecho de que las piezas deben asegurar varios tipos de funcion diferentes obligan a considerar las limitaciones maximas asociadas a cada tipo de funcion para cada una de las piezas, es decir, la precision dimensional, la resistencia mecanica, un material compatible con el corte, la estetica, etc...The fact that the pieces must ensure several different types of function forces us to consider the maximum limitations associated with each type of function for each of the pieces, that is, dimensional precision, mechanical resistance, a material compatible with the cut, aesthetics, etc ...
Ademas, debido a que algunas piezas estan referenciadas en las bombillas, las que estan referenciadas en el zocalo, la cadena cinematica se encuentra alargada, lo que lleva a incertidumbres sobre el cumplimiento de las funciones del producto, haciendo estas incertidumbres necesarios unos ajustes de configuracion, por ejemplo unos ajustes de la posicion de los contactos fijos.In addition, because some pieces are referenced in the bulbs, those that are referenced in the socket, the kinematic chain is elongated, which leads to uncertainties about the fulfillment of the product's functions, making these necessary uncertainties some configuration adjustments , for example, adjustments of the position of the fixed contacts.
El documento "WO 2011/033183 A1" describe un aparato de corte de corriente electrica segun el preambulo de la reivindicacion 1.Document "WO 2011/033183 A1" describes an electric current cutting apparatus according to the preamble of claim 1.
Descripcion de la invencionDescription of the invention
La presente invencion resuelve estos inconvenientes y propone un aparato de corte de corriente, en particular un disyuntor de acoplamiento, de concepcion simple, que permite reducir el numero de limitaciones impuestas a las diferentes piezas por sus funciones, de ah un coste de produccion reducido del aparato, y que permite disminuir el numero de ajustes necesarios, lo que simplifica por ello el montaje del aparato.The present invention solves these drawbacks and proposes a power cut-off apparatus, in particular a simple-design coupling circuit breaker, which allows reducing the number of limitations imposed on the different parts by their functions, hence a reduced production cost of device, and which allows to reduce the number of necessary adjustments, which simplifies the assembly of the device.
Para tal efecto, la presente invencion tiene por objeto un aparato de corte de corriente electrica del tipo anteriormente mencionado, estando este aparato caracterizado porque consta por una parte, de una pletina que consta de unos medios de referenciacion de un conjunto de piezas que tienen una funcion cinematica, comprendiendo este conjunto el mecanismo de control mencionado anteriormente, el(los) contacto(s) fijo(s), el(los) portacontactos movil(es), y por otra parte, una pieza de confinamiento del corte, denominado delimitador, que delimita al menos en parte la camara de corte, constando dicha pletina de unos medios de referenciacion de dicho delimitador.For this purpose, the present invention has as an object an electric current cut-off apparatus of the aforementioned type, this apparatus being characterized in that it comprises, on the one hand, a plate consisting of reference means of a set of parts having a kinematic function, this set comprising the above-mentioned control mechanism, the fixed contact (s), the mobile contact holder (s), and on the other hand, a piece of confinement of the cut, called the delimiter , which at least partially defines the cutting chamber, said plate consisting of reference means of said delimiter.
De este modo, esta pletina no asegura el confinamiento del corte y no tiene una funcion estetica, al ser interna al producto. Las unicas limitaciones impuestas a esta pletina son por tanto una cierta resistencia mecanica y una cierta precision dimensional.Thus, this plate does not ensure the confinement of the cut and does not have an aesthetic function, being internal to the product. The only limitations imposed on this plate are therefore a certain mechanical resistance and a certain dimensional precision.
La pieza de confinamiento asegura el confinamiento del corte sin tener otra funcion, lo que permite elegir el material unicamente segun esta limitacion. De este modo, se disminuye el numero de limitaciones asociadas a cada una de las piezas, de ah resulta un coste de fabricacion reducido del aparato.The confinement piece ensures the confinement of the cut without having another function, which allows to choose the material only according to this limitation. In this way, the number of limitations associated with each of the pieces is reduced, hence a reduced manufacturing cost of the apparatus.
Ademas, este tipo de arquitectura reduce la longitud de la cadena cinematica, debido a que las piezas tienen como referencia directa la pletina y ya no las piezas denominadas "bombillas", lo que hace mas seguro el cumplimiento de las funciones del producto y reduce el numero de ajustes de configuracion necesarios.In addition, this type of architecture reduces the length of the kinematic chain, because the pieces have as direct reference the plate and no longer the parts called "light bulbs", which makes the fulfillment of the functions of the product safer and reduces the number of configuration settings required.

Este conjunto esta destinado a montarse en una carcasa aislante (no representada), presentando esta carcasa una abertura destinada al paso de una manilla M destinada a la maniobra del aparato y que consta de unas aberturas de acceso a unos bornes de entrada y a unos bornes de salida destinados a conectarse electricamente respectivamente al contador y al cuadro electrico.In figure 1 a plate P is shown in which the different elements of an electrical protection apparatus such as a coupling circuit breaker that allows a particular to connect to the electrical network are mounted, said circuit breaker being intended to be placed between a meter and an electrical panel. This assembly is intended to be mounted in an insulating housing (not shown), this housing presenting an opening intended for the passage of a handle M intended for maneuvering the apparatus and consisting of access openings to input terminals and terminals of output intended to be connected electrically respectively to the meter and the electrical panel.
Este aparato es del tipo multipolar y consta principalmente de un mecanismo 1 de control y, segun esta realizacion particular, de cuatro conjuntos 2, 3, 4, 5 unipolares que comprenden tres conjuntos 2, 3, 4 destinados al corte de una fase y un conjunto 5 unipolar destinado al corte del neutro, estando asociado con cada uno de estos conjuntos un borne de entrada y un borne de salida. Cada conjunto 2, 3, 4, 5 unipolar consta de un contacto 6 fijo conectado electricamente por un conductor flexible en uno de los bornes, y de un contacto 7 movil conectado electricamente por un conductor flexible al otro de los bornes.This apparatus is of the multipolar type and consists mainly of a control mechanism 1 and, according to this particular embodiment, of four unipolar sets 2, 3, 4, 5 comprising three sets 2, 3, 4 intended for cutting a phase and a unipolar assembly 5 intended for cutting the neutral, an input terminal and an output terminal being associated with each of these sets. Each unipolar assembly 2, 3, 4, 5 consists of a fixed contact 6 electrically connected by a flexible conductor on one of the terminals, and a mobile contact 7 electrically connected by a flexible conductor to the other of the terminals.
Este contacto 7 movil esta soportado por un arbol 8 portacontactos movil comun a todos de los conjuntos unipolares, y apto para ser accionado en rotacion por un mecanismo 1 de control entre una posicion en la que los contactos 6, 7 fijo y movil estan abiertos y una posicion en la que los contactos fijo y movil estan cerrados.This mobile contact 7 is supported by a tree 8 mobile contact holder common to all of the unipolar assemblies, and capable of being operated in rotation by a control mechanism 1 between a position in which the fixed and mobile contacts 6, 7 are open and a position in which the fixed and mobile contacts are closed.
Se puede efectuar el control de la apertura de los contactos ya sea manualmente por la maniobra de una manilla M que pertenece al mecanismo 1 de control, o bien automaticamente mediante un dispositivo de proteccion que consta de un dispositivo 9 de proteccion magnetica contra las sobrecargas instantaneas de corriente electrica, y de un dispositivo 10 de proteccion termica contra las sobrecargas prolongadas de corriente electrica. De este modo, cada conjunto 2, 3, 4 unipolar de fase consta de un circuito electrico que consta, montados en serie con los contactos 6, 7 fijo y movil, de un dispositivo 10 de proteccion termica y de un dispositivo 9 de proteccion magnetica, pudiendo estos dos dispositivos montarse en serie o en paralelo segun el calibre. Estos dos dispositivos 9, 10 de proteccion constan cada uno de un actuador apto para actuar sobre una barra 11 denominada de transferencia, extendiendose dicha barra sustancialmente paralela a la direccion de alineacion de los conjuntos 2, 3, 4 unipolares y estando destinada a transmitir el orden de disparo o de apertura de los contactos al mecanismo 1 de control, que actua para accionar el arbol 8 portacontactos moviles en una posicion de apertura de los contactos 6, 7 de todos los conjuntos unipolares.It is possible to control the opening of the contacts either manually by maneuvering a handle M belonging to the control mechanism 1, or automatically by a protection device consisting of a magnetic protection device 9 against instantaneous overloads of electric current, and of a thermal protection device 10 against prolonged overloads of electric current. In this way, each unipolar phase set 2, 3, 4 consists of an electrical circuit consisting, mounted in series with the fixed and mobile contacts 6, 7, a thermal protection device 10 and a magnetic protection device 9 , these two devices being able to be mounted in series or in parallel according to the caliber. These two protection devices 9, 10 each consist of an actuator capable of acting on a transfer bar 11, said bar extending substantially parallel to the direction of alignment of the unipolar assemblies 2, 3, 4 and being intended to transmit the firing or opening order of the contacts to the control mechanism 1, which acts to drive the shaft 8 mobile contact holders in an opening position of the contacts 6, 7 of all unipolar assemblies.
Este aparato consta igualmente de un dispositivo 13 de proteccion diferencial apto para enviar un orden de apertura al mecanismo de control durante un desequilibro provocado por un receptor que presenta una corriente de defecto. El mecanismo 1 de control esta constituido por un primer mecanismo 14 denominado interruptor y un segundo mecanismo 15 denominado diferencial.This apparatus also consists of a differential protection device 13 capable of sending an opening order to the control mechanism during an imbalance caused by a receiver that has a fault current. The control mechanism 1 is constituted by a first mechanism 14 called a switch and a second mechanism 15 called a differential.
El funcionamiento de un aparato de proteccion electrica de este tipo es el siguiente:The operation of an electrical protection device of this type is as follows:
Cuando ocurre una sobrecarga prolongada o instantanea de corriente, los dispositivos de proteccion termica o magnetica actuan sobre una barra 11 de transferencia, que actua sobre una barra 12 de disparo denominada primera, que actua sobre una barra 16 de disparo denominada segunda, lo que provoca el disparo del mecanismo 15 diferencial por ruptura de enganche, lo que provoca el disparo del mecanismo 14 interruptor por ruptura de enganche, lo que controla la apertura del arbol 8 portacontactos.When a prolonged or instantaneous overload of current occurs, the thermal or magnetic protection devices act on a transfer bar 11, which acts on a firing bar 12 called first, which acts on a firing bar 16 called second, which causes the tripping of the differential mechanism 15 due to breakage of the coupling, which triggers the triggering of the switch mechanism 14 due to the breaking of the coupling, which controls the opening of the shaft 8 contact holder.
Cuando ocurre un desequilibrio entre varias fases, el rele del dispositivo de proteccion diferencial actua sobre la barra de disparo denominada segunda, lo que provoca el disparo del mecanismo 15 diferencial por ruptura de enganche, lo que provoca el disparo del mecanismo 14 interruptor por ruptura de enganche, lo que controla la apertura del arbol 8 portacontactos.When an imbalance occurs between several phases, the relay of the differential protection device acts on the trigger bar called second, which triggers the trip of the differential mechanism 15 due to a break in the coupling, which triggers the trip of the switch mechanism 14 due to a break in the hitch, which controls the opening of the tree 8 contact holders.
Durante una apertura manual, la maniobra de la manilla M controla los mecanismos 14 y 15, lo que controla la apertura de los contactos mediante una biela (no representada).During a manual opening, the maneuver of the handle M controls the mechanisms 14 and 15, which controls the opening of the contacts by means of a connecting rod (not shown).

Se ha realizado por tanto segun la invencion un aparato de corte de la corriente electrica de concepcion simple, que permite reducir el numero de limitaciones impuestas a cada una de las piezas. De este modo, esta pletina no asegura el confinamiento del corte y no tiene una funcion estetica, al ser interna al producto. Las unicas limitaciones en esta pieza son por tanto la resistencia mecanica y la precision dimensional debido al hecho que referencia todas las piezas que tengan una funcion cinematica.Therefore, according to the invention, a simple design electric current cutting device has been made, which allows reducing the number of limitations imposed on each of the pieces. Thus, this plate does not ensure the confinement of the cut and does not have an aesthetic function, being internal to the product. The only limitations in this piece are therefore the mechanical resistance and the dimensional precision due to the fact that it references all the pieces that have a kinematic function.
Ademas, debido a esta arquitectura, el conjunto constituido en la pletina es muy compacto, lo que permite aumentar aun la precision de los lados en esta pletina.In addition, due to this architecture, the set constituted on the plate is very compact, which allows to increase even the precision of the sides in this plate.
Al no tener la pieza de confinamiento otra funcion que la de asegurar el confinamiento del corte, esto permite elegir el material unicamente dependiendo de esta limitacion.Since the confinement part has no other function than to ensure the confinement of the cut, this allows the material to be chosen only depending on this limitation.
Ademas, esta arquitectura presenta la ventaja industrial de la arquitectura con dos bombillas, es decir, la posibilidad de cortar facilmente el producto en subconjuntos que pueden ensamblarse por separado luego agregarse juntos.In addition, this architecture presents the industrial advantage of the architecture with two bulbs, that is, the possibility of easily cutting the product into subsets that can be assembled separately then added together.
En efecto, la pieza de confinamiento puede soportar algunos elementos cinematicos que se referenciaran en la pletina durante la agregacion.Indeed, the confinement piece can support some kinematic elements that will be referenced on the plate during aggregation.
Por ultimo, esta arquitectura consume menos en terminos de numeros de piezas.Finally, this architecture consumes less in terms of number of pieces.
Por supuesto, la invencion no se limita al modo de realizacion descrito e ilustrado que solo se ha dado a modo de ejemplo.Of course, the invention is not limited to the embodiment described and illustrated that has only been given by way of example.
De este modo, por ejemplo, la invencion se ha descrito anteriormente cuando se aplica a un aparato de corte de corriente tetrapolar constituido por un conjunto unipolar para el neutro de la alimentacion y por tres conjuntos unipolares de fase equipados con un dispositivo de proteccion a la vez contra las sobrecargas permanentes y con un dispositivo de proteccion contra las sobrecargas instantaneas de corriente, constando igualmente dicho aparato de corte de corriente de un dispositivo de proteccion diferencial. Por supuesto, la invencion no se limita al caso de un aparato de corte de corriente tetrapolar y se aplica a todos los casos en los que se quiere cortar una alimentacion electrica.Thus, for example, the invention has been described above when applied to a tetrapolar current cutting apparatus consisting of a unipolar assembly for the neutral of the supply and three unipolar phase assemblies equipped with a protective device for the time against permanent overloads and with a protection device against instantaneous current overloads, said current cutting apparatus also comprising a differential protection device.
