    DESCRIPTION
    High voltage electrical device control system OBJECT OF THE INVENTION
    The present invention relates to a control system for high voltage electrical devices, said electrical devices being used to obtain the desired distribution of electrical energy, preventing consumers from running out of voltage, guaranteeing the protection of persons and electrical equipment, such as example the transformers, and therefore of application in networks of distribution of electrical energy of high tension. The object of the invention is to provide a drive capable of transmitting the movement of an actuator to at least one high voltage electrical device with multiple maneuvering positions that can be incorporated into any electrical equipment, in particular for the transmission of at least three positions. of maneuver, connection-cut and / or sectioning-earthing.
    BACKGROUND OF THE INVENTION
    The electrical equipment used in electric power distribution networks may comprise electrical maneuvering devices that perform the functions of connection, cutting and / or sectioning and grounding of the installation. Thus, in cases where there is, for example, a fault in the distribution line, a cut due to works, maintenance or optimization of the distribution of the load, such electrical devices can be operated to obtain the desired distribution of electrical energy, prevent Consumers run out of tension or guarantee the protection of people and electrical equipment such as transformers.
    These high voltage electrical devices may consist of automatic switches, load cut-off switches, etc., provided with a mobile contact and a fixed contact, including an earthing contact those electrical devices with three or more operating positions. For the execution of these maneuvering functions, a driving force produced by an actuator, such as a mechanical or magnetic actuator, is transmitted to the mobile contact of the high-voltage electrical device. The intervention of the actuator can be both voluntary, ordered by an operator regardless of the value of the current, or due to the action of a device sensitive to certain current values that directly or indirectly orders the opening of the circuit.

    The transfer of the actuating force between the actuator and the mobile contact of the electric device is carried out through a control system interspersed between them.
    There are control systems for high voltage electrical devices where the use of more than one actuator is necessary, since the actuators normally comprise only two functional positions and for a third maneuvering position, specifically for grounding, it is necessary the action of a second actuator. In other cases, several electrical devices are used in order to perform the functions of connecting and cutting and / or disconnecting maneuvering by means of an electrical device, and by another electrical device the grounding maneuvering function. In both cases, the use of one or more interlocking mechanisms is necessary to avoid the simultaneous maneuvering of the actuators or electrical devices, which is inconvenient since it is necessary to use very complex interlocking mechanisms that can sometimes give errors of operation, and on the other hand its implementation involves greater cost due to its complexity and the large number of elements necessary for its manufacture.
    There are solutions in which only one actuator is used for actuating the connection, cutting and / or sectioning and grounding maneuver functions of an electrical device. For this purpose, control systems interspersed between the actuator and the electric device are used, these control systems being responsible for transmitting the actuating force produced by the actuator and for selecting the maneuvering function in which said force must be engaged.
    In this regard, the US6603087B2 patent can be cited, where an actuator and a control system are defined. The control system is a spring transmission system comprising one or more springs, and where said springs are compressed due to the movement of the two-position actuator to then use their energy when opening or closing the contacts of the electrical device for perform two maneuver positions, specifically the connection and cut and / or section maneuver functions. The third maneuvering position, from the sectioning position to the grounding position and vice versa, is performed manually and by means of a lever that acts on the actuation axis of the contacts of the electrical device. Therefore, the control system transmits the force generated by the actuator to perform only two maneuvering functions, that of connection and cutting and / or sectioning. The actuator does not participate in the maneuver to take the electric device from sectioning to ground, or

    neither in the reverse maneuver. In short, by means of the actuator comprising two functional positions, the switching and cutting and / or sectioning maneuver functions are executed, while the grounding maneuvering function is carried out by means of a lever manually.
    Likewise, there are control systems for high voltage electrical devices in which the movement of the actuator is transmitted to the mobile contact of the high voltage electrical device through a rotating actuation axis, whereby the mobile contact of the high electrical device Tension describes a circular path, thus hindering the guidance of said mobile contact.
    DESCRIPTION OF THE INVENTION
    The invention relates to a control system for high voltage electrical devices, such as load cut-off switches, automatic switches, etc. with at least three operating positions, a first connection position, a second cutting and / or sectioning position and a third earthing position, which are applicable in high voltage electrical power distribution networks, and which comprise at least one fixed contact and one mobile contact, the mobile contact being connected to at least one drive of the system of the present invention.
    The control system of the present invention comprises at least one drive for the transmission of at least three operating positions (connection-cutting and / or sectioning and grounding) from an actuator, such as a mechanical or magnetic actuator , which comprises a first and a second functional position. For this, the drive comprises at least one transmission part of said at least three operating positions of at least one electrical device, which may be incorporated in some electrical equipment, such as a cell, a transformer, etc. This transmission piece can be displaced in one direction or another depending on the actuator displacement (depending on the functional position of the actuator) and depending on the position of at least one locking means of at least two positions that is integrated in said part. of transmission. The blocking means can slide into at least a first slot comprising the transmission part, being able to move between a first position and a second position, either manually or motorized. Keeping the locking means in its first position it blocks the transmission part, so that the movement of the actuator from its first functional position to its second position causes said transmission part to move in a sense of

    move towards the connection position and the latter moves the mobile contact of the electrical device to the connection maneuver position. Starting from this connection position, keeping the locking means in its first position and moving the actuator to its first functional position, the transmission part moves in a direction of backward towards the cutting and / or sectioning position and therefore the mobile contact of the electrical device passes to the cutting and / or sectioning maneuvering position.
    On the other hand, keeping the locking means in its second position it blocks the transmission part, so that the movement of the actuator from its first functional position to its second position causes the transmission part to move in a direction of advance towards the position grounding and the latter moves the mobile contact of the electrical device to the grounding maneuvering position. Also, starting from this grounding position, keeping the locking means in its second position and moving the actuator to its first functional position, the transmission piece is moved in a reverse direction towards the cutting and / or sectioning position and therefore the mobile contact of the electric device passes to the cutting and / or sectioning maneuvering position.
    In this way, by means of a single actuator and one drive, the desired electrical energy distribution can be obtained by means of an electrical device of at least three operating positions, which comprises the functions of connecting, cutting and / or sectioning and putting maneuvering. to ground, avoiding the use of complex interlocking mechanisms that can sometimes give operating errors, and thus reducing its manufacturing cost.
    The drive transmission part of the present invention is connected to the mobile contact of the electric device by means of at least one removable mechanical fixing element, such as a pin element.
    Preferably, the transmission part is connected to the actuator by means of at least one connecting rod and at least one actuation axis, said at least one connecting rod being responsible for joining the transmission part with the actuation axis and the latter being the responsible for joining said at least one connecting rod with the actuator. In this way, it is avoided that the mobile contact of the high voltage electrical device describes a circular path and it is achieved that said mobile contact can describe a straight path, thus facilitating its guidance and improving the general behavior of the high voltage electrical device.

    Also, the drive comprises at least one actuation shaft support. The transmission part comprises at least a second groove where said at least one connecting rod can slide. Finally, the transmission piece may comprise at least one cover that closes said at least one first and second groove.
    The possibility that the transmission part can be connected to the actuator only by means of at least one actuation axis has been contemplated.
