Definitions

  • the present invention relates to a switching device for application in power distribution network installations, such as, for example, transformation stations, photovoltaic plants, wind farms, electrical storage charge/discharge management centers, electric vehicle recharging stations, power line switching/transfer centers, etc.
  • the switching device is a device that has several fixed contacts configurable as inputs and outputs, and which can be electrically connected to each other by means of a movable contact, thus providing different applications and configurations to the switching device.
  • the electrical switchgear used in electrical power distribution networks comprises switching devices, such as, for example, switches, disconnectors, earthing switches, switches, selectors, etc.
  • the actuation of such switching devices is carried out to obtain the desired electric power distribution, to prevent consumers from being without voltage or to guarantee the protection of people and electrical equipment such as, for example, transformers.
  • the switching devices can even be combined with each other to thus be able to carry out different switching in the network and obtain the desired network configurations.
  • the actuation of the switching devices can be carried out both manually and motorized.
  • the switching devices comprise fixed contacts and movable contacts, so that the actuation of the movable contact supposes the separation or connection of said contact with respect to the fixed contact and therefore the opening or closing of the electrical circuit.
  • switching devices comprising a fixed contact and a movable contact in the case of hinge-type switching devices, or at least one pair of fixed contacts and a movable contact in the case of rotating switching devices, wherein the movable contact establishes the separation or connection between the pair of fixed contacts, thus opening or closing the electrical circuit.
  • the electrical switchgear and therefore also the switching devices, are installed inside modular enclosures or cells that, depending on variables such as the type of installation in question (subscriber or company transformation station, photovoltaic or wind power plants, etc.) or function performed by said electrical switchgear in an installation (protection cell, line cell, riser, etc.), there can be several enclosures or modular cells, each one performing its own function. In this way, by linking different modular cells it is possible to achieve different configurations of electrical diagrams, the extensibility on both sides of the cells and the reduction of the surface occupied at installations, which depending on the type of installation can be reduced, such as for example in wind farms where the electrical switchgear is installed inside the wind turbine towers.
  • the switching device object of the present invention solves the problems or needs mentioned above.
  • the switching device enables the grouping in a minimum space of most of the medium voltage functions that allow the operation of the electrical network, as well as the connection, power supply and protection of distribution transformers, thus obtaining greater flexibility when configuring different electrical diagrams.
  • the switching device which can have at least two switching positions, comprises at least two pairs of fixed contacts and one movable contact that can connect at least two of the fixed contacts to each other, so that the movable contact can comprise at least two ends that can make contact with said fixed contacts.
  • the fixed contacts correspond to different electrical branches, comprising some input branches and other output branches, so that the actuation of the movable contact connects / disconnects at least one pair of fixed contacts and therefore closes / opens an electrical circuit between at least an input electrical branch and at least one output electrical branch. Therefore, the movement of the movable contact opens or closes an electrical circuit that is selected between at least one input branch and at least one output branch, electrically connecting some first fixed contacts with some second fixed contacts to each other.
  • the switching device can comprise different configurations and therefore different applications, which increases the flexibility in the configuration of electrical diagrams in transformation stations, photovoltaic plants, wind farms, electric storage charge / discharge management centers, electric vehicle recharging stations, power line switching / transfer centers, etc.
  • the switching device can comprise the following configurations and applications:
  • the movable contact of the switching device of the invention is capable of performing a rotary movement actuated by a rotary axis, which in turn can be actuated manually or motorized.
  • switching device has short-circuit making ability is anticipated. In this way, when the switching device closes the electrical circuit, in those cases in which when closing the circuit a fault is generated, the switching device is able to withstand the increase in the current that passes through the contacts, being able to reach several kA in the closing switching.
  • the switching device (10) represented in Figures 1a-9c , comprises some pairs of fixed contacts (1, 1'), (2, 2') and (3, 3') and a movable contact (4) connecting at least two of the fixed contacts (1, 1'), (2, 2'), (3, 3') with each other.
  • the switching device (10) also comprises some input branches (A), (B), (C), corresponding to a first fixed contact of each of the pairs (1), (2), (3), and some output branches (D), (E), (F), corresponding to at least one second fixed contact of each of the pairs (1'), (2'), (3').
  • the movement of the movable contact (4) opens or closes an electrical circuit that is selected from at least one input branch (A), (B), (C) and at least one output branch (D), (E ), (F), electrically connecting the first fixed contacts (1, 2, 3) with the second fixed contacts (1', 2', 3') of each of the pairs.
  • the movable contact (4) of the switching device (10), as shown in the figures 1a-9c , has a rotary movement and is driven by a rotation axis (8), which in turn can be operated manually or motorized.
  • the possibility has also been considered that switching device (10) has short-circuit making capacity. In this way, when the switching device (10) closes the electrical circuit, in those cases in which a fault is generated when closing the circuit, the switching device (10) is able to withstand the increase in current that passes through the contacts, both the fixed pairs (1, 1'), (2, 2'), (3, 3'), and the movable one (4), being able to reach several kA in the closing switching.
  • FIGS 1a-9c show different representations of the switching device (10), which depending on the number of electrical branches and their corresponding fixed contacts, the switching device (10) can give rise to a plurality of configurations and applications, thus providing greater flexibility when it comes to making different electrical diagrams at the installations where it shall be arranged:
