Definitions

  • the invention relates to a high-voltage switching device with a vacuum interrupter and a switchgear with a high-voltage switching device.
  • the invention relates to a method for producing a high-voltage switching device with a vacuum interrupter.
  • Switchgear with which the electrical energy is distributed is used in networks of electrical power lines. Switchgears have switchgear that create or separate an electrically conductive connection between electrical contacts. In high-voltage or medium-voltage networks, high-voltage switching devices are used which meet the electrical requirements for the high voltages in high-voltage or medium-voltage networks. The voltages of the high-voltage networks are generally over 52 kV and the medium-voltage networks between 1kV and 52kV.
  • High-voltage switching devices which have a vacuum interrupter in which the electrical contacts are arranged.
  • switching devices are also known in which the electrical contacts are in a gas atmosphere made of insulating gas, for example SF 6 .
  • insulating gas for example SF 6
  • the use of vacuum interrupters offers the advantage that load currents and short-circuit currents can be interrupted in a relatively small volume without the risk of hot switching gases being emitted.
  • a particularly long insulation section is required in air-insulated switchgear, which is why these switchgear take up a particularly large amount of space.
  • Switchgear with a vacuum interrupter are, for example, from the DE 31 12 776 A1 and DE 40 27 723 A1 known.
  • the known vacuum interrupters have an immovable contact element with a contact and a contact element movable in the axial direction of the vacuum interrupter with a contact, which is made up of the vacuum interrupter extends.
  • the conductor parts forming the current path are connected to the contact elements.
  • the movable contact element is actuated by an actuating member which is sealed off from the housing body of the switching device.
  • the actuator can be driven by an electric drive unit.
  • the DE 27 39 811 A1 describes a high-voltage switching device with a housing body, in which a vacuum switching chamber is provided which has an immovable switching contact element and a switching contact element movable in the axial direction, to which conductor parts forming the current path are connected.
  • the movable switch contact element which extends out of the vacuum interrupter chamber, is connected via an insulation body to an actuating member which is movable in the axial direction.
  • a cavity filled with an insulation liquid is formed in the housing body, into which the movable switching contact element extends from the vacuum switching chamber.
  • the invention has for its object to provide a high-voltage switching device that requires the formation of a relatively short insulation path and thus has a more compact structure compared to the prior art.
  • the invention is also based on the object of providing a switchgear assembly which is distinguished by a particularly compact construction.
  • Another object of the invention is to provide a method with which a high-voltage switching device with a particularly compact structure can be produced simply and inexpensively.
  • the high-voltage switching device has a one-part or multi-part housing body in which a vacuum interrupter is provided.
  • the vacuum switching chamber has an immovable switching contact element and a switching contact element movable in the axial direction, the movable switching contact element extending out of the vacuum switching chamber and being connected via an insulation body to an actuating member movable in the axial direction.
  • the conductor parts forming the current path are connected to the immovable switch contact element and the movable switch contact element.
  • An actuator is understood to mean all means with which the movable switching contact element can be axially displaced in order to close or open the contacts.
  • the actuator can consist of one or more parts.
  • a cavity filled with an insulation liquid is formed in the housing body, the movable switching contact element extending from the vacuum chamber into the cavity and the actuating member in turn extending from the cavity filled with insulation liquid.
  • the high-voltage switching device is distinguished by the fact that a sealing arrangement that seals the actuating member from the housing body is provided in the cavity filled with insulating liquid. This ensures a safe interruption of the load current and the short-circuit current with a relatively short insulation path. As a result, the high-voltage switching device can have a compact structure.
  • a sealing arrangement is understood to mean all means with which a liquid-tight seal with respect to the housing body or parts of the housing body can take place.
  • An arrangement of the sealing arrangement within the cavity is understood to mean that at least the parts of the sealing arrangement that form an assembly that is essential for the sealing are arranged within the cavity. This does not exclude that individual parts which are connected to the sealing arrangement cannot also be located outside the cavity, for example they can have an outwardly facing surface.
  • the high-voltage switching device provides that the sealing arrangement has a bellows which is arranged in the cavity and which surrounds the actuating member which extends from the liquid-filled chamber in order to seal the actuating member with respect to the housing body. Since the bellows is a component of the sealing arrangement that takes up a relatively large amount of space, the switching device has a more compact structure than a switching device in which a bellows for sealing is arranged outside a chamber filled with insulating liquid or an insulating gas. Such a switching device is for example from the DE 31 13 776 A1 known.
  • the bellows can be connected to earth potential. Since the bellows is not in an air-filled room, but within the chamber filled with insulation liquid, the risk of flashover of parts of the switching device that are at a high potential is reduced. Therefore, the high-voltage switching device can be made compact.
  • a particularly preferred embodiment provides that the cavity is closed with a cover that is sealed with respect to the housing body, for example with a removable plate, one end piece of the bellows being sealed in a liquid-tight manner with respect to the cover. Closing the cavity with a cover offers advantages for the manufacture of the high-voltage switching device.
  • the housing body comprises a plastic body that at least partially surrounds the liquid-filled cavity.
  • the plastic body can consist of one or more plastic elements which are connected to one another.
  • the plastic body advantageously consists of a plurality of plastic elements which can be produced simply and inexpensively by the injection molding process and then connected to one another. Individual plastic elements can be inserted into one another and / or glued or welded together.
  • plastic body not only improves the electrical properties of the switching device, but also simplifies its manufacture. Corners and edges of the live conductor parts of the switching device located within the plastic body or the plastic elements, for example a movable conductor part that is electrically connected to the movable contact element, cause a strongly inhomogeneous electrical field.
  • the plastic elements can have rounded corners and edges and consist of an electrically conductive plastic, preferably mixed with a conductive material, for example carbon. These plastic elements can have the same potential as the live components. As a result, the electric field becomes more homogeneous to the outside, so that field control takes place.
  • the housing body preferably comprises a potting body, which at least partially surrounds the vacuum interrupter and the plastic body. Since the plastic elements have the same potential as the live components, the outer shell of the housing body consisting of a casting compound, for example cast resin, is less stressed.
  • a particularly preferred embodiment of the plastic body comprises a first shell-shaped plastic element and a second shell-shaped plastic element, the conductor parts forming the current path comprising a movable conductor part which is electrically connected to the movable contact element.
  • the movable conductor part is arranged in the cavity and is at least partially enclosed by the first and second plastic elements.
  • the corners and edges of the plastic body enclosing the movable conductor part or the corners and edges of its plastic elements are rounded and the plastic body or the plastic elements consist of an electrically conductive plastic, so that they can assume the same potential as the movable conductor part.
  • the plastic body comprises a cylindrical plastic element which at least partially surrounds the sealing arrangement.
  • This plastic element is preferably not conductive and therefore cannot carry any potential.
  • the plastic element can ensure the isolation between potential-carrying components and the actuator, which is at ground potential.
  • the plastic element preferably has lamellae, so that the creepage distance is increased.
  • the plastic body is sealed off from the vacuum interrupter, so that casting resin cannot get into a gap between the plastic body and the vacuum interrupter.
  • Cutting edges are preferably provided on the plastic body, the housing body of the vacuum interrupter chamber, which can consist of metallic or ceramic materials, being at least partially enclosed by a material into which the cutting edges can cut when the components are assembled.
  • the switchgear according to the invention has one or more switchgear according to the invention.
  • a high-voltage switching device can be produced simply and inexpensively, in which the movable switching contact element extends out of the vacuum switching chamber into a cavity filled with an insulating liquid.
  • the plastic elements of the plastic body serve, on the one hand, to prevent the potting compound from getting into the volume enclosed by the plastic elements during casting, for example with epoxy resin. This ensures that the components remain movable within the plastic elements. Since pressures greater than 1 bar can occur during casting, the mechanical strength of the plastic elements must be given. In order to prevent cast resin from penetrating at the interfaces of the plastic elements, they can be inserted into one another and / or glued or welded to one another.
  • a casting mold which corresponds in shape and dimensions to the contour of the housing body of the switching device.
  • the vacuum interrupter and the plastic body or the plastic elements are introduced into the casting mold. These plastic elements then form part of the casting mold.
  • the shape and dimensions of the plastic elements therefore determine the shape and dimensions of the housing body, in particular of the parts of the housing body in which the vacuum interrupter chamber is located and in which the chamber to be filled with insulation liquid is formed.
  • the space between the wall of the casting mold and the vacuum interrupter and the plastic body is encapsulated with a potting compound to create a encapsulating body enclosing the vacuum interrupter and the plastic body, in which a cavity enclosed by the plastic body remains.
  • the actuating member and the insulating body as well as the sealing arrangement and possibly further components are inserted into the cavity of the switching device and the cavity is filled with the insulating liquid, the cavity being closed with a cover which is sealed off from the potting body or plastic body.
  • the cover is preferably sealed off from the plastic body.

  • the upper end piece of the lower section 8B is supported on a compression spring 9 in the cylinder space of the upper section 8A.
  • the upper section 8A also displaces, so that the movable switching contact element 5 is displaced axially.
  • the compression spring 9 serves to dampen the shocks when the actuating member 8 is actuated.
  • the actuating member 8 is driven by a drive unit (not shown) which displaces the lower section 8B in the axial direction.
  • the actuating member 8 is sealed against the housing body 1 with a sealing arrangement 10 in a liquid-tight manner.
