Description

Beschreibungdescription
Elektrische Vorrichtung mit einem HaltegerüstElectric device with a holding frame
Die Erfindung betrifft eine elektrische Vorrichtung mit einem Haltegerüst und mit Hochspannung beaufschlagbaren und von dem Haltegerüst gehaltenen Komponenten.The invention relates to an electrical device with a holding frame and can be acted upon by high voltage and held by the holding frame components.
Derartige elektrische Vorrichtungen sind beispielsweise aus dem Bereich der Hochspannungs-Gleichstromübertragung (HGÜ) bekannt in Form von Ventiltürmen, die unter Ausbildung eines Umrichters miteinander verschaltet sind. Der Umrichter ist zwischen einem Wechselspannungsnetz und einem Gleichspannungsnetz der HGÜ-Anlage angeordnet und ist zur Umwandung von Wechselspannung in Gleichspannung oder umgekehrt eingerichtet. Jedes seiner Ventiltürme weist eine Vielzahl an Submodu- len auf. Die während des Betriebs des Ventilturms mit Hochspannung beaufschlagten Submodule sind in einem Haltegerüst gegeneinander und gegenüber der Umgebung isoliert angeordnet.Such electrical devices are known for example from the field of high-voltage direct current (HVDC) transmission in the form of valve towers, which are interconnected to form an inverter. The converter is arranged between an AC voltage network and a DC voltage network of the HVDC system and is set up to convert AC voltage into DC voltage or vice versa. Each of its valve towers has a large number of submodules. The submodules subjected to high voltage during operation of the valve tower are arranged in a holding stand against each other and isolated from the environment.
Aus dem Bereich der Überspannungsabieiter, welche der Ableitung von Überspannungen in elektrischen Energieversorgungsnetzen dienen, sind sogenannte Metalloxid- Überspannungsableiter bekannt, welche mit Hochspannung beaufschlagbare Metalloxid-Widerstände aufweisen. Die Metalloxid-Widerstände bilden innerhalb des Überspannungsabieiters aufeinander geschichtet eine Widerstandssäule, welche von einem Haltegerüst aus faserverstärkten Kunststoff-Vollstäben im Inneren des Überspannungsabieiters gehalten wird.From the field of surge arrester, which serve to dissipate overvoltages in electrical energy supply networks, so-called metal oxide surge arresters are known, which have high-voltage loadable metal oxide resistors. Within the surge arrester, the metal oxide resistors form a resistance column stacked on one another, which is held by a holding framework made of fiber-reinforced plastic solid bars inside the surge arrester.
Ferner sind aus dem Brückenbau tragende Stützkonstruktionen bekannt, welche als Profilträger ausgestaltete und aus faserverstärktem Kunststoff gefertigte Stützelemente aufweisen. Der Erfindung liegt die Aufgabe zugrunde, eine elektrische Vorrichtung der eingangs genannten Art anzugeben, welche sich durch besonders geringe Herstellungskosten des Haltegerüsts auszeichnet .Further supporting structures are known from the bridge construction, which have designed as a profile carrier and made of fiber-reinforced plastic support elements. The invention has for its object to provide an electrical device of the type mentioned, which is characterized by particularly low manufacturing cost of the support structure.
Die Aufgabe wird erfindungsgemäß bei einer elektrischen Vorrichtung der eingangs genannten Art dadurch gelöst, dass das Haltegerüst zumindest ein aus faserverstärktem Kunststoff bestehendes Halteelement aufweist, an dem mindestens eine Kom- ponente elektrisch isoliert befestigt ist, wobei das Halteelement als Profilträger ausgestaltet ist.The object is achieved according to the invention in an electrical device of the type mentioned above in that the holding frame has at least one holding element made of fiber-reinforced plastic, to which at least one component is fastened in an electrically insulated manner, wherein the holding element is designed as a profile carrier.
Der Erfindung liegt die Erkenntnis zugrunde, dass - entgegen der bisher herrschenden Meinung - die elektrisch isolierenden Eigenschaften von faserverstärkten Kunststoff-Vollstäben sich nicht wesentlich dadurch verändern, dass von den bislang üblichen massiven Vollstäben abgewichen wird. Dies gilt insbesondere auch im Hochspannungsbereich. Mit Vollstäben seien hier Stäbe mit kreisförmigem oder rechteckigem Querschnitt bezeichnet. Die Vollstäbe könnten auch mit Vollprofil-Stäben bezeichnet werden. Aus dem Stand der Technik sind faserverstärkte Kunststoff-Vollstäbe oder Kunststoff-Platten zum Isolieren von Hochspannung bekannt. Diese werden aus im Pressverfahren hergestellten faserverstärkten Kunststoffplatten gewonnen. Hierzu werden die Vollstäbe aus dem Plattenmaterial ausgesägt oder ausgefräst beziehungsweise die Kunststoffplatten in geeigneter Weise mechanisch bearbeitet. Die isolierenden Eigenschaften der so hergestellten Vollstäbe sind für den Einsatz im Hochspannungsbereich erprobt und geeignet. Der Einsatz von Profilträgern zu Isolationszwecken im Hochspannungsbereich wurde bisher nicht in Betracht gezogen, da diese aufgrund ihrer äußeren Form aus dem faserverstärkten Kunst- stoffplattenmaterial nicht oder nur unter unwirtschaftlich hohem Aufwand herstellbar wären. Im Gegensatz hierzu werden die aus dem Brückenbau bekannten Profilträger aus faserverstärktem Kunststoff im sogenannten Pultrosionsverfahren hergestellt. Der Einsatz von im Pultrosionsverfahren hergestelltem faserverstärkten Kunststoffmaterial zu Isolationszwecken im Hochspannungsbereich wurde ebenfalls bisher nicht in Betracht gezogen, da dessen Isolationsvermögen bislang als unzureichend eingeschätzt wurde.The invention is based on the finding that - contrary to the prevailing opinion - the electrically insulating properties of fiber-reinforced plastic solid rods do not change significantly by deviating from the usual solid solid rods. This is especially true in the high voltage range. With solid bars here rods with circular or rectangular cross section are designated. The solid bars could also be referred to as solid profile bars. Fiber-reinforced plastic solid bars or plastic plates for insulating high voltage are known from the prior art. These are obtained from fiber-reinforced plastic plates produced by pressing. For this purpose, the solid rods are sawn out of the plate material or milled or machined the plastic plates in a suitable manner. The insulating properties of the solid rods thus produced are tested and suitable for use in the high voltage range. The use of profile beams for insulation purposes in the high voltage range has not been considered, since they would not be produced due to their outer shape of the fiber-reinforced plastic sheet material or only at uneconomical cost. In contrast to this will be the profile beam known from the bridge construction made of fiber-reinforced plastic produced in the so-called anti-corrosion process. The use of fiber-reinforced plastic material produced in the process of plate corrosion for insulation purposes in the high-voltage range has also not been considered so far, since its insulation capacity has hitherto been considered inadequate.
Bei den im Kunststoff enthaltenen Fasern kann es sich um Glasfasern handeln. Dieses Material ist im Handel auch unter der Abkürzung GFK bekannt.The fibers contained in the plastic may be glass fibers. This material is also known in trade under the abbreviation GFK.
Erfindungsgemäß ist somit bei einer elektrischen Vorrichtung mit einem Haltegerüst und mit Hochspannung beaufschlagbaren und von dem Haltegerüst gehaltenen Komponenten die Möglichkeit gegeben, die zu befestigenden Komponenten mittels leichter und preiswerter Halteelemente isoliert am Haltegerüst zu befestigen. Hierzu wird mindestens ein Halteelement aus faserverstärktem Kunststoff verwendet, welches ein belastungsoptimierter Profilträger ist. Dies ermöglicht eine besonders leichte Bauweise des Haltegerüstes, welches somit geringeren Belastungen ausgesetzt ist und insgesamt leichter und somit kostengünstiger ausgeführt werden kann.According to the invention is thus given in an electrical device with a holding frame and can be acted upon by high voltage and held by the holding frame components the opportunity to secure the components to be fastened by means of lightweight and inexpensive retaining elements isolated on the holding frame. For this purpose, at least one retaining element made of fiber-reinforced plastic is used, which is a load-optimized profile carrier. This allows a particularly lightweight construction of the holding frame, which is thus exposed to lower loads and can be made lighter overall and thus more cost-effective.
Einen derartigen Profilträger als Halteelemente zu verwenden, an dem mindestens eine mit Hochspannung beaufschlagte Komponente elektrisch isoliert befestigt ist und welcher aufgrund dessen selbst mit Hochspannung beaufschlagt ist und zum Isolieren dieser Hochspannung dient, wurde bisher nicht in Be- tracht gezogen, da eine vom Vollstab abweichende Geometrie als nachteilig für die isolierenden Eigenschaften eines faserverstärkten Kunststoff-Halteelements angesehen wurde.To use such a profile carrier as holding elements to which at least one component subjected to high voltage is fixed in an electrically insulated manner and which itself is subjected to high voltage and serves to isolate this high voltage has not hitherto been taken into consideration, since a deviating from the solid bar Geometry was considered to be detrimental to the insulating properties of a fiber reinforced plastic retaining element.
Profilträger weisen einen hinsichtlich des Gewichts und hin- sichtlich der Belastbarkeit optimierten Querschnitt auf. Beispielsweise kann es sich bei dem Querschnitt um einen T- förmigen Querschnitt handeln.Beams have a weight and visibly optimized load capacity. For example, the cross section may be a T-shaped cross section.
Derart belastungsoptimierte Profile sind aus dem Stand der Technik bei Halteelementen, deren stützende und tragende Funktion im Vordergrund steht, bekannt - beispielsweise aus dem Brückenbau.Such load-optimized profiles are known from the prior art in holding elements whose supporting and supporting function is in the foreground known - for example, from the bridge.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass das Haltegerüst und die mit Hochspannung beaufschlagbaren und von dem Haltegerüst gehaltenen Komponenten ein Ventilturm eines Umrichters ausbilden, wobei die Komponenten zweipolige Submodule umfassen, die in Reihe geschal- tet sind und einen Energiespeicher sowie eine Leistungshalbleiterschaltung aufweisen.According to an advantageous embodiment of the invention, it is provided that the holding frame and the components which can be subjected to high voltage and held by the holding frame form a valve tower of an inverter, wherein the components comprise two-pole submodules which are connected in series and have an energy store and a power semiconductor circuit ,
Die Ventiltürme eines Umrichters sind zu einer Stromrichterschaltung miteinander verbunden. Die Stromrichterschaltung ist beispielsweise Teil einer Anlage zur Energieübertragung. Bei der Anlage kann es sich beispielsweise um eine Hochspannungs-Gleichstrom-Übertragungsanlage handeln. Bei derartigen Anlagen sind die Ventiltürme im Gebäude einer Umrichterstation untergebracht und isoliert auf dem Boden oder an der Decke der Umrichterstation aufgehängt. Durch das erfindungsgemäß leichte Haltegerüst kann die den Ventilturm an der Decke haltende Tragkonstruktion kleiner dimensioniert werden, wodurch weitere Kosten eingespart werden können.The valve towers of an inverter are connected together to form a converter circuit. The power converter circuit is part of a system for energy transmission, for example. The system may be, for example, a high voltage DC transmission system. In such systems, the valve towers are housed in the building of a converter station and suspended in isolation on the floor or on the ceiling of the inverter station. By means of the support frame according to the invention, the support structure supporting the valve tower on the ceiling can be dimensioned smaller, whereby further costs can be saved.
Es kann auch als vorteilhaft angesehen werden, dass das Halteelement mindestens zwei in einer waagerechten Ebene im Haltegerüst angeordnete Submodule gegeneinander isoliert und an dem Haltegerüst isolierend abstützt. Die während des Betriebs der Ventile mit Hochspannung beaufschlagten und in Reihe geschalteten zweipoligen Submodule bilden die sogenannten Ventil-Zweige des Umrichters aus. Hierbei sind die Submodule in dem Haltegerüst geeignet iso- liert angeordnet, beispielsweise in zwei übereinander angeordneten waagerechten Ebenen im Haltegerüst. Um diese in einer waagerechten Ebene angeordneten Submodule geeignet zu befestigen ist erfindungsgemäß mindestens ein aus faserverstärktem Kunststoff bestehendes Halteelement, welches ein Profilträger ist, an den Submodulen und dem Haltegerüst befestigt. Die Submodule können in geeignetem Abstand voneinander an dem Profilträger aufgehängt oder an der Oberseite des Profilträgers aufmontiert sein. Wie bereits weiter oben beschrieben wurde, weist jedes Submodul zweckmäßigerweise einen Energiespeicher, beispielsweise einen Kondensator, sowie eine Leistungshalbleiterschaltung auf. Die Leistungshalbleiterschaltung verfügt über steuerbare Leistungshalbleiter, mit denen die an dem Energiespeicher abfallende Spannung oder eine Nullspannung an den Anschluss des Submoduls gelegt werden kann. Auf diese Weise ist ein so genannter Multilevel- Umrichter bereitgestellt.It can also be considered advantageous for the retaining element to isolate at least two submodules arranged in a horizontal plane in the support frame from one another and to support them in an insulating manner on the support frame. The high voltage applied during operation of the valves and connected in series two-pole submodules form the so-called valve branches of the inverter. In this case, the submodules are suitably insulated in the support frame, for example in two horizontal levels arranged one above the other in the support frame. In order to fix these arranged in a horizontal plane submodules suitable according to the invention at least one existing fiber-reinforced plastic holding element, which is a profile carrier, attached to the submodules and the holding frame. The submodules may be suspended at a suitable distance from each other on the profile carrier or mounted on the top of the profile carrier. As already described above, each submodule expediently has an energy store, for example a capacitor, as well as a power semiconductor circuit. The power semiconductor circuit has controllable power semiconductors with which the voltage dropping across the energy store or a zero voltage can be applied to the terminal of the submodule. In this way, a so-called multilevel inverter is provided.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist das Halteelement ein T-Profilträger, U-Profilträger, I- Profilträger oder L-Profilträger .According to an advantageous embodiment of the invention, the holding element is a T-profile carrier, U-profile carrier, I-profile carrier or L-profile carrier.
Derartige Halteelemente weisen einen belastungsoptimierten Querschnitt auf bei gleichzeitig besonders geringem Gewicht.Such holding elements have a load-optimized cross section with at the same time particularly low weight.
Es kann auch als vorteilhaft angesehen werden, dass das Halteelement ein viereckiges Hohlprofil aufweist. Ein Halteelement mit einem derartigen gewichts- und belas- tungsoptimierten Querschnitt ist quer zur Längsrichtung in allen Richtungen gleichermaßen belastbar.It can also be considered advantageous that the holding element has a quadrangular hollow profile. A holding element with such a weight and load optimized cross section is equally loadable in all directions transversely to the longitudinal direction.
Weitere zweckmäßige Ausgestaltungen und Vorteile der Erfindung sind Gegenstand der Beschreibung von Ausführungsbeispielen der Erfindung unter Bezug auf die Figur der Zeichnung, wobei gleiche Bezugszeichen auf gleich wirkende Bauteile verweisen .Further expedient refinements and advantages of the invention are the subject matter of the description of embodiments of the invention with reference to the figure of the drawing, wherein like reference numerals refer to the same acting components.
