Definitions
- the present invention relates to an electric switching device with a dual-track cam according to the preamble of claim 1.
- circuit-breaker or disconnector installations in particular at high voltage, for example as GIS-type ( g as i nsultated s witchgear) or AIS ( a ir i nsulated s witchgear) metal-wrapped substations, it is intended to be able to connect but above all to disconnect electrical connection elements, such as a dedicated male electrical connector to be inserted into or removed from a female electrical connector.
- an electrical switching device adapted to connect or disconnect said connectors mechanically.
- This electric single-track cam switching device is here in closed connection mode, that is to say that the male electrical connector (6) is inserted into the female electrical connector (7).
- the female connector (7) is in the position closest to the base (1).
- the one-off rotational coupling means (3 ') is located far from said input guide or the female connector (7), while inversely the first slider (8) is located closer to said input guide or the female connector (7). Therefore, the male connector (6) coupled to the second arm (5) itself coupled to the first slider (8) is in the most recessed position in said input guide or the female connector (7). Said first slider (8) is thus in initial position on a first end of the curvilinear track (9).
- Figure 2 present according to figure 1 the same single-track cam electrical switching device, however in intermediate disconnection mode, that is to say when the moment (Mo) exerted by the driving end of the first driving arm (4) of the cam (3) is in a range of maximum values and thus allows the cam to rotate under a high torque drive, while the drive force (Fd) parallel to the axis of the male connector is ensured by removing the female connector (7) further from the fixed base (1) relative to the figure 1 .
- the male connector (6) disengages from the female connector (7) thereby creating an arc-contact break that will be commonly blown by a neutral gas inlet or SF6 during the following the disconnection.
- the first slider (8) slides in the track (9) whose curvilinear geometry hook-shaped or "L" rounded is adapted to minimize frictional forces of the slider with edges of said track.
- Figure 3 present according to figure 2 the same single-track cam electrical switching device, however in final disconnection mode for a total mechanical and electrical separation of the male and female connectors (6, 7).
- the moment (Mo) exerted by the training end of the first arm the drive (4) of the cam (3) thus returns in a range of minimum values.
- the first slider (8) reaches its final position at a second end of the curvilinear track (9).
- An object of the present invention is to provide an effective electrical switching device allowing a speed of disconnection of the male and female connectors faster, in particular for a high voltage application such as a circuit breaker or disconnector under GIS metal envelope station.
- a set of subclaims also has advantages of the invention.
- the said device is further characterized in that the second track (11) comprises a linear track portion having a main axis (12) passing through the pivot point (2) of the cam.
- the electric switching device with a bi-track cam according to figure 5 is here in closed connection mode analogously to the figure 1 that is, the male electrical connector (6) is inserted into the female electrical connector (7).
- the second slider (10) is at one end of the second track (11) furthest from the pivot point (2).
- the first slider (8) is also at one end of the first track (9) furthest from the pivot point (2).
- the first track has a curved geometric profile (then linear) so that for a range of positions of the first slide on this profile in association with a range of positions of the second slider in the second track, a drive Linear of the second arm undergoes an acceleration which is here a considerable advantage also presented in figure 8 .
- Figure 6 represents the electrical switching device according to figure 5 , however in intermediate disconnection mode, analogous to the intermediate disconnection mode of the figure 2 .
- the male connector (6) disengages from the female connector (7) thereby creating an arc contact break that will commonly be blown by a neutral gas supply or SF6 during the subsequent disconnection.
- the second slider (10) is at another end of the second track (11) closest to the pivot point (2).
- the first slider (8) then traveled more than 30% on the first track (9) towards the other end of the first track (9) closest to the pivot point (2).
- the driving force (Fd) parallel to the axis of the male connector (6) is ensured by the withdrawal of the female connector (7) further from the fixed base (1) relative to the figure 5 .
- the resultant force (Fr) in the main direction - here also advantageously parallel to the axis of the male connector - of the first driving arm (4) on the cam (3) is thus equal to 100% of the force drive (Fd) parallel to the axis of the male connector.
- the first arm is thus coupled to a mechanism for moving said arm in a linear direction identical to that of the axis of said first arm, free of rotation relative to the support base.
- the first and second elongate arms form parallel movements along their axes for any position of their respective slider with one of the tracks of the cam. Even if this configuration of "parallel" transmission of effort is optimal because allows a complete transmission of said efforts, a rotation of the first arm can however be tolerated.
- the first slider (8) slides in the track (9) whose curvilinear geometry hook-shaped or "L" rounded is adapted to minimize frictional forces of the slider with edges of said track.
- the device according to the invention thus provides that the second track is a linear oblong opening.
- the first and second tracks describe a form question mark (?) Whose lower point similar to the second track is however oblong. This geometry of the tracks thus makes it possible to provide an acceleration to the first slider (8) in order to more quickly remove the male connector (6) from the input guide of the female connector (7).
- an inlet guide in the form of a nozzle (7 ') driven by the first arm (4) and the cam in the disconnection mode allows the male connector (6) of the female connector to be slidably withdrawn in the said nozzle ( 7), said nozzle (7 ') being movable relative to the support base (1).
- Figure 7 represents the electrical switching device according to figure 5 or 6 , however in the final disconnect mode, analogous to the final disconnect mode of the figure 3 .
- the male connector (6) is thus completely disengaged from the female connector (7).
- the second slider (10) is again at the initial end of the second track (11) furthest from the pivot point (2).
- the first slide (8) then traveled the entire first track (9) towards the other end of the first track (9) closest to the pivot point (2).
- Figure 8 shows an example of a displacement speed diagram of the first and second arms of said device, to illustrate the advantageous effect of acceleration described above.
- the curves represented are a value (%) of displacement (Di) as a function of a time unit (Tu) between 0 and 1.
- a first curve (DS) thus indicates the constant speed of withdrawal of the first arm (4) ( when removing the input guide 7).
- a second curve (SC) indicates the driving speed of the male connector (6) for a device according to one of the Figures 1 to 3 (or 4): we can see that in the time interval [0,2; 0.7], said withdrawal speed of the second arm or of the male connector (6) is equal (and opposite) to that of the withdrawal of the first arm (4).
- a third curve (DC) indicates the driving speed of the male connector (6) for a device according to one of the Figures 5 to 7 it can be seen that in the interval (HS) of time [0.31; 0.46], said withdrawal speed of the second arm or the male connector (6) is increased (and opposite) to that (SC) of the withdrawal of the first arm (4), there is indeed an acceleration of a factor of 1.5 over this interval (HS) at high speed, which illustrates the effect desired by the device according to the invention, in order to make the disconnection faster and thus arc cutting more effective.

Dans des installations de disjoncteur ou sectionneur, en particulier sous haute tension, par exemple comme des postes à enveloppe métallique de type GIS (gas insultated switchgear) ou AIS (air insulated switchgear), il est visé de pouvoir connecter, mais surtout de déconnecter des éléments de connexion électrique, tel qu'un connecteur électrique mâle dédié à être inséré dans ou retiré d'un connecteur électrique femelle. A ce titre, il est prévu un dispositif de commutation électrique apte à connecter ou déconnecter mécaniquement les dits connecteurs.In circuit-breaker or disconnector installations, in particular at high voltage, for example as GIS-type ( g as i nsultated s witchgear) or AIS ( a ir i nsulated s witchgear) metal-wrapped substations, it is intended to be able to connect but above all to disconnect electrical connection elements, such as a dedicated male electrical connector to be inserted into or removed from a female electrical connector. As such, there is provided an electrical switching device adapted to connect or disconnect said connectors mechanically.
Particulièrement en mode de déconnexion, il est requis d'atteindre une ouverture rapide et fiable entre le connecteur mâle et le connecteur femelle. A ce titre, un exemple de dispositif connu de commutation est donné au travers des

- l'extrémité d'entrainement du premier bras d'entrainement de la came est formée par un moyen de couplage rotatif ponctuel (3') distinct de l'axe de pivot (2) afin de pouvoir exercer un moment (Mo) sur ladite extrémité et par conséquent de faire pivoter la came.

- a first drive arm (4) having a drive end coupled to the cam for pivoting relative to the hub about the pivot axis,
- a second arm (5) for electrical commutation by linear drive along an axis of said arm,
- said second arm having:
- a) a first end provided with a male electrical connector (6) dedicated to be inserted into or removed from a female electrical connector (7) and;
- b) a second end driven by pivoting of the cam by means of a sliding coupling, said coupling comprising a first slide (8) secured to the second end of the second arm and sliding in a first curvilinear track (9) of the cam,

Ce dispositif de commutation électrique à came mono-piste est ici en mode de connexion fermée, c'est-à-dire que le connecteur électrique mâle (6) est inséré dans le connecteur électrique femelle (7). En d'autres termes, le connecteur femelle (7) est en position la plus rapprochée de l'embase (1). Sachant que ce guide d'entrée est couplé à l'autre extrémité du premier bras d'entrainement (4) de la came, le moyen de couplage rotatif ponctuel (3') est localisé loin du dit guide d'entrée ou du connecteur femelle (7), alors que inversement le premier coulisseau (8) est localisé au plus près du dit guide d'entrée ou du connecteur femelle (7). Par conséquent, le connecteur mâle (6) couplé au deuxième bras (5) lui-même couplé au premier coulisseau (8) est en position la plus enfoncée dans le dit guide d'entrée ou du connecteur femelle (7). Le dit premier coulisseau (8) est ainsi en position initiale sur une première extrémité de la piste curviligne (9).This electric single-track cam switching device is here in closed connection mode, that is to say that the male electrical connector (6) is inserted into the female electrical connector (7). In other words, the female connector (7) is in the position closest to the base (1). Knowing that this input guide is coupled to the other end of the first drive arm (4) of the cam, the one-off rotational coupling means (3 ') is located far from said input guide or the female connector (7), while inversely the first slider (8) is located closer to said input guide or the female connector (7). Therefore, the male connector (6) coupled to the second arm (5) itself coupled to the first slider (8) is in the most recessed position in said input guide or the female connector (7). Said first slider (8) is thus in initial position on a first end of the curvilinear track (9).

Le dit dispositif se caractérise enfin en ce que la deuxième piste (11) comprend une portion de piste linéaire ayant un axe principal (12) passant par le point de pivot (2) de la came.The said device is further characterized in that the second track (11) comprises a linear track portion having a main axis (12) passing through the pivot point (2) of the cam.
Le dispositif de commutation électrique à came bi-piste selon
Lors d'un prochain mode de déconnexion (intermédiaire, puis finale) selon les figures suivantes 6 et 7, la première piste a un profil géométrique de glissement incurvé (puis linéaire) de sorte que pour un intervalle de positions du premier coulisseau sur ce profil en association à un intervalle de positions du deuxième coulisseau dans la deuxième piste, un entrainement linéaire du deuxième bras subit une accélération qui est ici un avantage considérable aussi présenté en
Ici, le deuxième coulisseau (10) se trouve à une autre extrémité de la deuxième piste (11) la plus proche du point de pivot (2). Le premier coulisseau (8) a alors parcouru plus de 30% sur la première piste (9) en direction de l'autre extrémité de la première piste (9) la plus proche du point de pivot (2).Here, the second slider (10) is at another end of the second track (11) closest to the pivot point (2). The first slider (8) then traveled more than 30% on the first track (9) towards the other end of the first track (9) closest to the pivot point (2).
L'effort d'entrainement (Fd) parallèle à l'axe du connecteur mâle (6) est assuré par le retrait du connecteur femelle (7) plus loin de l'embase fixe (1) par rapport à la
Par soucis de clarté dans le présent document, les efforts de frictions ne sont toujours pas considérés. Egalement, le premier coulisseau (8) glisse dans la piste (9) dont la géométrie curviligne en forme de crochet ou « L » arrondi est adaptée pour minimiser des efforts de frictions du coulisseau avec des bords de ladite piste.For the sake of clarity in this document, friction efforts are still not considered. Also, the first slider (8) slides in the track (9) whose curvilinear geometry hook-shaped or "L" rounded is adapted to minimize frictional forces of the slider with edges of said track.
Au plus simple, le dispositif selon l'invention prévoit ainsi que la deuxième piste est une ouverture oblongue linéaire. Il est à noter que la première et la deuxième pistes décrivent une forme en point d'interrogation (?) dont le point inférieur assimilé à la deuxième piste est toutefois oblong. Cette géométrie des pistes permet ainsi de fournir une accélération au premier coulisseau (8) afin de retirer plus vite le connecteur mâle (6) du guide d'entrée du connecteur femelle (7).At the simplest, the device according to the invention thus provides that the second track is a linear oblong opening. It should be noted that the first and second tracks describe a form question mark (?) Whose lower point similar to the second track is however oblong. This geometry of the tracks thus makes it possible to provide an acceleration to the first slider (8) in order to more quickly remove the male connector (6) from the input guide of the female connector (7).
Enfin, un guide d'entrée sous forme de tuyère (7') entrainée par le premier bras (4) et de la came en mode de déconnexion permet de retirer par coulissement dans la dite tuyère le connecteur mâle (6) du connecteur femelle (7), la dite tuyère (7') étant mobile par rapport à l'embase de support (1) .Finally, an inlet guide in the form of a nozzle (7 ') driven by the first arm (4) and the cam in the disconnection mode allows the male connector (6) of the female connector to be slidably withdrawn in the said nozzle ( 7), said nozzle (7 ') being movable relative to the support base (1).
Ici, le deuxième coulisseau (10) se trouve de nouveau à l'extrémité initiale de la deuxième piste (11) la plus éloignée du point de pivot (2). Le premier coulisseau (8) a alors parcouru toute la première piste (9) en direction de l'autre extrémité de la première piste (9) la plus proche du point de pivot (2).Here, the second slider (10) is again at the initial end of the second track (11) furthest from the pivot point (2). The first slide (8) then traveled the entire first track (9) towards the other end of the first track (9) closest to the pivot point (2).
