Equipo de corte electrico de media tension que utiliza la tecnica de corte en el vado Campo tecnicoMedium voltage electric cutting equipment that uses the cutting technique in the ford Technical field
La presente invencion se refiere a un equipo de corte electrico de media tension que consta por fase al menos de dos aparatos de corte, constando cada aparato de corte de un seccionador situado en una lmea electrica, constando dicho seccionador de un primer contacto denominado fijo y de un segundo contacto denominado movil, estando uno de estos dos contactos conectado electricamente a una barra de transmision de la corriente, mientras que el otro contacto esta conectado, respectivamente para todos los aparatos de corte, a unos circuitos electricos diferentes, constando cada aparato de corte de unos medios para realizar la funcion de desconexion y de unos medios para garantizar la funcion de corte.The present invention relates to a medium voltage electrical cutting equipment consisting of at least two cutting devices per phase, each cutting device consisting of a disconnector located in an electric line, said disconnector consisting of a first contact called fixed and of a second contact called mobile, one of these two contacts being electrically connected to a current transmission bar, while the other contact is connected, respectively for all cutting devices, to different electrical circuits, each device consisting of cutting of some means to perform the disconnection function and of some means to guarantee the cutting function.
Estado de la tecnica anteriorState of the prior art
Se conoce la utilizacion desde los anos 1970 por los principales fabricantes de interruptores de media tension de la tecnologfa de separacion mecanica de los contactos electricos en el SF6 con el fin de cortar las corrientes asignadas de los interruptores.The use since the 1970s is known by the main manufacturers of medium voltage switches of the mechanical separation technology of the electrical contacts in the SF6 in order to cut off the assigned currents of the switches.
Esta solucion presenta numerosas ventajas en lo que se refiere a la compacidad de los aparatos, su coste y sus prestaciones. Estas ventajas se deben principalmente a las excepcionales propiedades ffsicas del SF6: rigidez dielectrica, conductividad termica, estabilidad qmmica, electronegatividad, no toxicidad...This solution has numerous advantages in terms of the compactness of the devices, their cost and their performance. These advantages are mainly due to the exceptional physical properties of SF6: dielectric strength, thermal conductivity, chemical stability, electronegativity, non-toxicity ...
Sin embargo, el gas SF6 presenta el inconveniente de formar parte de los gases de importante efecto invernadero.However, SF6 gas has the disadvantage of being part of the important greenhouse gases.
Tambien se conoce la utilizacion de las ampollas de vado, las cuales permiten cortar corrientes importantes sin estar colocadas necesariamente en el SF6, pero nunca se utilizan para las funciones de interruptor debido a su muy elevado coste.The use of ford ampoules is also known, which allow cutting important currents without necessarily being placed in the SF6, but they are never used for switch functions due to their very high cost.
Se conoce la patente FR 2937786 que describe un principio que permite reducir el coste de esta tecnologfa. El dispositivo descrito en esta patente consta de una derivacion en la cual se coloca una ampolla de vado que garantiza el corte. Esta derivacion esta inactiva en regimen permanente y unicamente la recorre la corriente electrica cuando el seccionador ha comenzado su movimiento de apertura, mediante una transferencia progresiva de la corriente de la lmea principal la derivacion. Al estar por lo general la ampolla en reposo, no tiene que dimensionarse con las limitaciones electricas y dielectricas restrictivas de regimen permanente. Este tipo de sistema puede, por lo tanto, utilizarse para todos los interruptores dispuestos en un mismo tanque y para todas las fases.Patent FR 2937786 is known which describes a principle that allows reducing the cost of this technology. The device described in this patent consists of a shunt in which a ford ampoule is placed that guarantees the cut. This branch is inactive in permanent regime and is only traversed by the electric current when the disconnector has started its opening movement, by means of a progressive transfer of the current from the main line to the branch. Since the blister is usually at rest, it does not have to be sized with the restrictive electrical and dielectric limitations of the permanent regime. This type of system can therefore be used for all switches arranged in the same tank and for all phases.
Sin embargo, este tipo de sistema no permite no obstante, en terminos de coste, aproximarse a los costes de los interruptores que utilizan el gas SF6.However, this type of system does not allow, however, in terms of cost, to approximate the costs of the switches that use SF6 gas.
El documento EP 2 565 897 da a conocer un equipo de corte electrico que corresponde al preambulo de la reivindicacion 1.EP 2 565 897 discloses an electric cutting equipment corresponding to the preamble of claim 1.

Detailed description of a particular preferred embodiment of the invention
En las figuras, se observa un cuadro C electrico de media tension que consta, para cada una de las fases electricas de la red, de tres interruptores 1, 2, 3 electricos montados uno junto al otro respectivamente en tres lmeas electricas a, b, c paralelas entre sf, y que se extienden siguiendo una direccion sustancialmente perpendicular a la direccion longitudinal de una barra de distribucion electrica 4.In the figures, a medium voltage electrical panel C is observed which consists, for each of the electrical phases of the network, of three electrical switches 1, 2, 3, mounted next to each other respectively in three electrical lines a, b, c parallel to each other, and extending along a direction substantially perpendicular to the longitudinal direction of an electric distribution bar 4.
En esta realizacion particular, los dos primeros interruptores 1, 2 forman el bucle de distribucion secundario mientras que el tercer interruptor 3 es un interruptor de alimentacion del aparato electrico de un usuario.In this particular embodiment, the first two switches 1, 2 form the secondary distribution loop while the third switch 3 is a power switch of a user's electrical apparatus.
Cada interruptor 1, 2, 3 consta de un seccionador 5, 6, 7 que consta de un contacto 5a, 6a, 7a fijo conectado electricamente a la barra 4 y de un contacto 5b, 6b, 7b movil formado por una cuchilla rotativa conectada electricamente a un circuito electrico.Each switch 1, 2, 3 consists of a disconnector 5, 6, 7 consisting of a fixed contact 5a, 6a, 7a electrically connected to the bar 4 and a mobile contact 5b, 6b, 7b formed by a rotating blade electrically connected To an electric circuit.
El segundo 2 de los interruptores esta asociado a un circuito 8 de derivacion que consta de una ampolla 9 de vado que consta de un contacto 9a fijo conectado electricamente a la barra 4, en un punto situado sustancialmente al mismo nivel de la barra que el punto de conexion del contacto 6a fijo del segundo seccionador 6 a la barra 4, y de un contacto 9b movil conectado mecanica y electricamente a un medio 13 de accionamiento denominado segundo, el cual esta conectado mecanica y electricamente a un primer medio 12 y a un tercer medio 14 de accionamiento, como se explicara a continuacion.The second 2 of the switches is associated with a bypass circuit 8 consisting of a blister 9 consisting of a fixed contact 9a electrically connected to the bar 4, at a point located substantially at the same level of the bar as the point of connection of the fixed contact 6a of the second disconnector 6 to the bar 4, and of a mobile contact 9b mechanically and electrically connected to an actuation means 13 called second, which is mechanically and electrically connected to a first means 12 and a third means 14, as will be explained below.

El soporte 19 de contacto 9b movil de la ampolla 9 tambien esta conectado de manera articulada a la porcion de barra 16 asociada al segundo seccionador 6 en un punto situado entre los dos extremos de esta porcion de barra 16, de tal modo que la rotacion en el sentido contrario a las agujas del reloj de esta porcion de barra 16 provoca el cierre de los contactos de la ampolla 9.The mobile contact support 9b of the vial 9b is also connected in an articulated manner to the bar portion 16 associated with the second sectioner 6 at a point located between the two ends of this bar portion 16, such that the rotation in counterclockwise of this bar portion 16 causes the closure of the blister contacts 9.
El funcionamiento del equipo se va a describir a continuacion en referencia a las figuras.The operation of the equipment will be described below in reference to the figures.
En funcionamiento normal, como se ilustra en la figura 1, todos los interruptores 1,2 y 3 estan cerrados con el fin de alimentar el bucle de distribucion secundario constituido por los dos primeros interruptores 1, 2 y el interruptor de alimentacion del cliente constituido por el tercer interruptor 3. En este ejemplo de realizacion, se considerara que la red alimenta directamente al primer interruptor 1 y que este alimenta a su vez una parte aguas abajo de la red que esta situada a su derecha. En lo que se refiere al primer interruptor 1, el recorrido de la corriente se representa con las flechas. La corriente que circula a traves de los otros dos interruptores no esta representada.In normal operation, as illustrated in Figure 1, all switches 1,2 and 3 are closed in order to feed the secondary distribution loop consisting of the first two switches 1, 2 and the customer power switch consisting of the third switch 3. In this exemplary embodiment, it will be considered that the network directly feeds the first switch 1 and that it in turn feeds a downstream part of the network that is located to its right. As regards the first switch 1, the current path is represented by the arrows. The current flowing through the other two switches is not represented.
Al comienzo de la apertura del primer interruptor 1 como se ilustra en la figura 2, se produce una conmutacion de la corriente, fase durante la cual la corriente que proviene del contacto 5b movil del primer seccionador 5, va a pasar a la vez por el contacto 5a fijo del primer seccionador y por la porcion de barra 16 del medio de accionamiento denominado segundo asociado al segundo seccionador 6, pasando por la primera porcion de barra 15, la porcion de union 18a de la varilla 18 situada entre las dos porciones de barra 15, 16 asociadas respectivamente a los dos primeros seccionadores, y a continuacion a traves de la segunda porcion de barra 16 y a continuacion se dirige hacia la ampolla 9 para juntarse con el juego de barras 4. Este movimiento de rotacion del contacto 5b movil del primer seccionador 5 en el sentido de las agujas del reloj ha generado una rotacion en el sentido contrario a las aguas del reloj de las porciones de barra, y en particular de la segunda porcion de barra 16, lo que provoca el contacto movil de la ampolla de vacfo en una posicion de cierre.At the beginning of the opening of the first switch 1 as illustrated in Figure 2, there is a switching of the current, phase during which the current that comes from the mobile contact 5b of the first disconnector 5, will pass through the fixed contact 5a of the first disconnector and by the bar portion 16 of the actuator means called second associated with the second sectioner 6, passing through the first bar portion 15, the junction portion 18a of the rod 18 located between the two bar portions 15, 16 associated respectively with the first two disconnectors, and then through the second bar portion 16 and then directed to the vial 9 to join the bar set 4. This rotational movement of the mobile contact 5b of the first disconnector 5 clockwise has generated a counterclockwise rotation of the bar portions, and in particular of the second bar portion 16, which causes the mobile contact of the vacuum ampoule in a closed position.
Al continuar con la apertura del primer interruptor 1, el contacto 5b movil de este primer seccionador 5 se separa completamente de su contacto 5a fijo asociado, como se ilustra en a figura 3. Durante esta fase, la corriente ya solo pasa por tanto por los contactos de la ampolla de vacfo 9.By continuing with the opening of the first switch 1, the mobile contact 5b of this first disconnector 5 is completely separated from its associated fixed contact 5a, as illustrated in Figure 3. During this phase, the current already only passes through the Vacuum blister contacts 9.
Cuando el contacto 5b movil del seccionador 5 este lo suficientemente alejado de su contacto 5a fijo asociado, el segundo medio 13 de accionamiento asociado al segundo seccionador 6 va por tanto a comenzar a abrir los contactos de la ampolla de vacfo, por medio de un sistema no descrito aqu pero que se describe en el documento FR 2 937 786, lo que va a tener rapidamente como efecto cortar la corriente electrica, posicion ilustrada en la figuraWhen the mobile contact 5b of the disconnector 5 is sufficiently far from its associated fixed contact 5a, the second actuating means 13 associated with the second disconnector 6 will therefore begin to open the contacts of the vacuum ampoule, by means of a system not described here but described in document FR 2 937 786, which will quickly have the effect of cutting the electric current, position illustrated in the figure
4.Four.
Al continuar con la apertura del interruptor, el contacto 5b movil del seccionador 5 va entonces a liberarse de la porcion de barra 15 del primer medio 12 de accionamiento, hasta alcanzar su posicion final de apertura que permitira garantizar el seccionamiento de la tension aguas arriba y aguas abajo del interruptor, posicion ilustrada en la figuraBy continuing with the opening of the switch, the mobile contact 5b of the disconnector 5 will then be released from the bar portion 15 of the first actuating means 12, until it reaches its final opening position that will allow the sectioning of the upstream voltage to be guaranteed and downstream of the switch, position illustrated in the figure
5. Durante esta etapa, las porciones de barra 15, 16, 17 van por tanto a recuperar su posicion inicial representada en la figura 1, por medio de la presencia de muelles de retorno no ilustrados.5. During this stage, the bar portions 15, 16, 17 will therefore recover their initial position shown in Figure 1, by means of the presence of return springs not illustrated.
La operacion de cierre se realizara mediante la maniobra del seccionador en el sentido inverso, lo que no producira ningun efecto sobre la porcion de barra del medio de accionamiento correspondiente, hasta que entre en contacto el contacto 5b movil con el contacto 5a fijo.The closing operation will be carried out by maneuvering the disconnector in the reverse direction, which will not produce any effect on the bar portion of the corresponding actuating means, until the mobile contact 5b comes into contact with the fixed contact 5a.
El funcionamiento de los otros dos interruptores 2, 3 no se describira, ya que es el mismo que el del primer interruptor 1.The operation of the other two switches 2, 3 will not be described, since it is the same as that of the first switch 1.
La invencion podra utilizarse de manera ventajosa en los cuadros que comprenden entre 2 y 5 interruptores.The invention may be used advantageously in the panels comprising between 2 and 5 switches.
Por otra parte, tambien se puede pensar en integrar este dispositivo que consta de la ampolla de vacfo en cualquier lugar dentro de un tanque (y, por lo tanto, no necesariamente asociado a un interruptor). En este caso, se colocaran de manera ventajosa unos medios de accionamiento mecanicos en todos los interruptores de la celda, estando estos por tanto conectados electrica y mecanicamente al dispositivo de accionamiento del contacto movil de la ampolla. Aunque mas voluminosa, esta alternativa sera interesante en el caso de que se deseara no limitar demasiado electricamente la zona de los interruptores. Esto podra, por ejemplo, permitir reducir la anchura de la celda en detrimento de su altura, lo que puede a veces ser menos cntico con respecto a la huella de la celda.On the other hand, you can also think of integrating this device consisting of the vacuum ampoule anywhere inside a tank (and, therefore, not necessarily associated with a switch). In this case, mechanical actuation means will be advantageously placed in all the switches of the cell, these being therefore electrically and mechanically connected to the device for activating the mobile contact of the vial. Although more voluminous, this alternative will be interesting if it is desired not to limit the area of the switches too electrically. This could, for example, allow reducing the width of the cell to the detriment of its height, which may sometimes be less critical with respect to the cell's footprint.
Por medio de la invencion, se reduce considerablemente el coste del corte en el vacfo por el hecho de que solo se utiliza un sistema como el descrito en la patente citada con anterioridad, por fase, en el cuadro de distribucion, estando las demas funciones equipadas solo con unos sistemas de accionamiento mecanicos. Con el fin de permitir el corte de la corriente en un interruptor que no esta equipado con ampollas de vacfo, una conexion mecanica (barra) conecta las diferentes partes moviles de los sistemas de accionamiento entre estas. De este modo, cuando se actua sobre un sistema, el conjunto de los demas sistemas (que incluyen el que comprende la ampolla de vacfo) se accionan simultaneamente.By means of the invention, the cost of cutting in the vacuum is reduced considerably by the fact that only a system such as that described in the patent cited above is used, per phase, in the distribution chart, the other functions being equipped Only with mechanical drive systems. In order to allow the cutting of the current in a switch that is not equipped with vacuum ampoules, a mechanical connection (bar) connects the different moving parts of the drive systems between them. In this way, when acting on a system, all other systems (which include the one comprising the vacuum ampoule) are actuated simultaneously.
Por supuesto, la invencion no esta limitada a la forma de realizacion descrita e ilustrada que solo se da a tftulo ilustrativo.Of course, the invention is not limited to the described and illustrated embodiment that is only given by way of illustration.
Asf pues, por ejemplo, aunque en la realizacion anteriormente descrita e ilustrada, el sistema de corte completo que consta de la ampolla de vacfo se ha anadido en el interruptor del centro, este tambien podna haberse asociado a otro de estos interruptores.Thus, for example, although in the previously described and illustrated embodiment, the complete cutting system consisting of the vacuum bulb has been added to the center switch, it may also have been associated with another of these switches.
