Definitions
- the present invention relates to an electricalmaschinean order, such as in particular an electrical isolating switch device.
- the present invention relates in particular to an isolating switch device which allows improved gas insulation of an isolating distance between two contact pieces.
- Such isolating switching devices usually comprise a first contact piece and a second contact piece, which are arranged so as to be movable relative to one another and can be separated from one another in a separating zone or can be arranged in a contacting manner.
- WO 2018/114204 A1 and DE 102016 226 034 A1 describe an electrical switching device comprising a first switching contact piece and a second switching contact piece, the switching contact pieces being movable relative to one another and the first switching contact piece being encompassed by a fluid flow guide device, the fluid flow guide device being the The first switch contact piece engages around the shell side in such a way that an envelope contour of a flow channel delimited between the fluid flow guide device and the first switch contact piece is larger, at least at its end facing the second switch contact piece, than the envelope contour of the first switch contact piece at its end facing the second switch contact piece.
- EP 3309 810 A1 and DE 102016 219 812 A1 describe a switching arrangement having a blowing device and a first switching contact with a first and a second switching contact piece. Between the switching contact pieces he stretches at least temporarily a switching path. The loading device operates both the first switching contact and a second switching contact.
- DE 102013 205 945 A1 describes an isolating switch device with a first contact piece and a second contact piece, which can be moved relative to one another and a separation zone is formed between de NEN in the separated state, is equipped with a compression device with a compression space for receiving a fluid.
- the compression space protrudes at least temporarily into the separation zone.
- the object of the present invention is to at least partially overcome the disadvantages known from the prior art.
- the object of the present invention is to provide a solution by which at least in part an electrical circuit arrangement with a simple structure and a defined and reliable operation can be provided.
- the object is achieved according to the invention at least in part by an electrical switching device with the Merkma len of claim 1.
- the object is achieved according to inven tion at least in part also by a gas-insulated switchgear with the features of claim 10.
- Preferred embodiments of the invention are in the Subclaims described in the description or the figures, with further claims in the subclaims or in the description or the figures Features described or shown individually or in any combination can represent an object of the invention if the context does not clearly indicate the opposite.
- a switching arrangement is described with a plurality of at least two contact arrangements and a Beblasungsanord voltage for blowing the contact arrangements with insulating gas, the at least two contact arrangements each having a first contact piece and a second contact piece, which can be moved relative to each other in order to be touch the state of the first contact piece and the second contact piece to form an electrical connection and to form an isolation path in a separate state, the blowing arrangement having at least two Blasvo lumen, a first contact arrangement being able to be supplied with insulating gas through a first blowing volume and wherein a second contact arrangement can be supplied with insulating gas through a second blowing volume.
- Such a configuration allows a simple structure with a defined blowing of a plurality of contact arrangements.
- a switching arrangement with a plurality of at least two contact arrangements is provided to interrupt a switching path or to bridge a switching path.
- the switching arrangement can have at least a first contact arrangement and a second contact arrangement.
- Each of the contact arrangements has a first and a second switching contact piece.
- a switching path can extend at least temporarily between the switching contact pieces of a switching contact.
- the impedance of the switching path can be changed.
- the switching path can be bridged mechanically, for example, or its impedance can be changed in some other way.
- the switching path can also be bridged by means of an arc. In In a simple case, a relative movement of the switching contact pieces of the respective switching contact can be provided for bridging the switching path.
- At least one of the switching contact pieces can be arranged to be movable, whereas the other switching contact piece of the respective contact arrangement can be arranged in a stationary manner.
- both the first and the second switching contact are designed to be movable or drivable, so that a movement is coupled to both the first switching contact and the second switching contact to trigger a switching process.
- first contact piece and the second contact piece are movable relative to each other in order to form an electrical connection in a mutually touching state of the first contact piece and the second contact piece and to form an insulation path in a mutually separated state.
- the plurality of contact arrangements can be arranged so as to be electrically isolated from one another. It is thus possible to switch electrical potentials / currents that differ from one another in the Wegkon contacts.
- Various devices can be used as the switching arrangement. For example, disconnectors and earthing switches can function as a switching arrangement.
- load switches or circuit breakers serve as the switching arrangement.
- the switching contact pieces of the respective contact arrangement are combined arcing and main contacts.
- This enables the switching contact pieces to be structured in a simple manner. If necessary, sections of the contact pieces can be equipped with an erosion-resistant material. This allows low-mass and low-impedance contact pieces to be formed.
- a contact piece can, for example, be bush-shaped or bolt-shaped.
- a bolt-shaped contact piece can for example, it can also be made essentially tubular.
- the switching arrangement is able to carry out a switching operation in a multi-phase system.
- the power to be transmitted can be increased.
- the blowing arrangement makes it possible to blow the switching path with a fluid flow during a switching operation, i.e. while bridging a switching path and / or while creating a switching path, and to remove any impurities in the switching path.
- the blowing arrangement can preferably drive a gaseous fluid.
- the blowing arrangement drives a liquid fluid.
- Fluorine-containing fluids in particular are suitable for flowing through the contact sets.
- fluoroketone or fluoronitrile can be used as fluids.
- natural fluids such as nitrogen, carbon dioxide, oxygen as a component of the insulation gas or synthetic air can also be used for blowing. It is also possible to use fluid mixtures which have at least one of these components.
- the blowing arrangement can be designed differently from the switching contact pieces, so that the performance of the blowing arrangement can be adjusted without having to intervene in the structure of a contact piece.
- the blowing arrangement has at least two blowing volumes, wherein a first contact arrangement can be supplied with insulating gas through a first blowing volume and wherein a second contact arrangement can be supplied with insulating gas through a second blowing volume.
- the switching arrangement described here proposes providing a plurality of blowing volumes which are adapted to the number of contact arrangements or to the number of phases in the circuit. It is therefore not, as is known from the prior art, a blow volume provided which supplies all contact arrangements with an insulating gas, but a plurality of blow volumes is seen in front of the number of contact arrangements.
- blowing ducts of this type. This can simplify the structure and thus make the manufacture of the switching arrangement more cost-effective, if necessary.
- the structure and the assembly of the switching arrangement can be simplified ver by reducing the compo le.
- Correct dimensioning of the blow volume for example designed as a blow piston, also seems to be important.
- the size can advantageously be matched exactly to the breaking currents, but also be as small as possible for switching on. This is particularly the case when, as described above, special measures such as flow channels or flap mechanisms should be undesirable.
- Such a dimensioning of the blowing volumes is easily possible within the scope of the present invention, which can allow a further significant advantage with regard to the construction and operation of the switching arrangement.
- the present invention can therefore further prevent the switching speed from being influenced.
- a switching arrangement according to the present invention is thus aimed at replicating a blowing system.
- each contact arrangement can be supplied separately with insulating gas.
- the blow volume can be made relatively small, since with this concept the distances between the contact arrangements do not have to be bridged, for example by the spatial expansion of the blow volume.
- the present invention can be particularly advantageous if a number of more than two contact arrangements are provided.
- it can be particularly advantageous if, in addition, at least a third blowing volume and a third contact arrangement are provided, the third contact arrangement being able to be provided with insulating gas by the third blowing volume.
- first contact arrangement can be supplied with insulation gas exclusively through the first blow volume and that the second contact arrangement can be supplied with insulation gas exclusively through the second blow volume and that, if applicable, that is to say, the third contact arrangement can only be supplied by the third blowing volume can be supplied with insulating gas.
- each contact arrangement is thus assigned a blowing volume, it being possible for a supply of insulation gas to be provided through this blowing volume.
- the respective blowing volume can be adapted exactly to the respective contact arrangement, for example with regard to the insulation gas or with regard to the volume, which allows particularly safe and effective operation.
- it can thus be provided that at least partially different insulation gases are present in the blowing volumes present or that the blowing volumes are at least partially of different sizes.
- the Beblasungsanord voltage has a volume-displacing piston-cylinder arrangement, at least one contact piece from the first contact arrangement and the second contact arrangement and optionally the third contact arrangement is fixedly arranged on the piston-cylinder arrangement.
- a separate piston-cylinder arrangement to be provided for each contact arrangement, which is formed in a gas-tight manner in particular with respect to the respective other piston-cylinder arrangements.
- a volume-displacing piston-cylinder arrangement has the advantage that a pressure difference can be generated repeatedly in the piston-cylinder arrangement, so that a fluid flow can be generated in a simple manner.
- a pressure difference can be generated by a relative movement of a piston to a surrounding cylinder.
- the relative movement of a piston and a cylinder of the piston-cylinder arrangement can be synchronized with a switching process (e.g. a switching movement) of the contact arrangement, so that a differential pressure of a fluid is only generated in the piston-cylinder arrangement as required. This prevents a hold of pressurized fluid over a long period of time.
- a switching process e.g. a switching movement
- At least one of the contact pieces in particular functionally identical contact pieces of the first and second switching contact or of the first and second contact arrangement, can be arranged on the blowing arrangement.
- the contact pieces can be arranged on the piston or on the cylinder or on the piston and the cylinder, in particular carried by them.
- first blowing volume, the second blowing volume and, if appropriate, the third blowing volume are designed to be gas-tight with respect to one another.
- At least one contact piece is attached to a wall of the piston-cylinder arrangement, in particular inserted into a wall of the piston-cylinder arrangement.
- a wall, in / on which a contact piece is inserted / attached, can preferably limit the blowing volume of the piston-cylinder arrangement.
- the contact piece inserted / attached to the wall is positioned close to the blowing volume, so that a flowing fluid can be transported from the blowing volume to the contact pieces over short distances.
- the contact piece can be at least partially supported by the piston-cylinder arrangement, in particular by a wall.
- a contact piece of the first contact arrangement, a contact piece of the second contact arrangement and possibly a contact piece of the third contact arrangement are arranged on a common wall element, the common wall element being a wall of the first piston-cylinder arrangement, the second Piston-cylinder arrangement and optionally the third piston-cylinder arrangement.
- a conveyance of the insulation fluid can thus be controlled jointly, although the blow volumes made available can still be separated from one another.
- a contact piece of the first contact arrangement, a contact piece of the second contact arrangement and possibly a contact piece of the third contact arrangement are each arranged on a separate wall element, the separate wall elements each having a separate wall of the first piston -Cylinder assembly, the second piston-cylinder assembly and possibly the third piston-cylinder assembly form.
- a particularly high degree of flexibility can be allowed with regard to the switching operations. This is because the aforementioned advantages can be provided in an effective manner even when the switching operations of the contact arrangement are to take place independently of one another.
- the control of the delivery of the insulation fluid into a contact arrangement is independent of the other switching operations.
- At least one Blasvo lumen is at least partially filled with synthetic air.
