Kontaktanordnung für ein Hochspannungs-Schaltgerät sowie des¬ sen Verwendung und Herstellung Contact arrangement for a high-voltage switching device and the ¬ sen use and manufacture
Die Erfindung betrifft eine Kontaktanordnung für ein Hochspannungs-Schaltgerät sowie dessen Verwendung und Herstel¬ lung. Die Kontaktanordnung umfasst wenigstens einen bewegli¬ chen Kontaktarm, mit wenigstens zwei Kontaktelementen zum elektrischen Kontaktieren eines Gegenkontaktstücks . The invention relates to a contact arrangement for a high-voltage switching device and its use and manufacture ¬ ment. The contact arrangement comprises at least one bewegli ¬ contact surfaces, having at least two contact elements for electrically contacting a mating contact piece.
Hochspannungs-Schaltgeräte werden zum Schalten hoher Spannungen und Ströme verwendet, insbesondere im Bereich von 70 bis 800 kV. Hochspannungs-Schaltgeräte sind z. B. Erdungsschalter und Trennschalter, insbesondere Drehtrennschalter, Kniehebeltrennschalter, oder Einfachschwenktrennschalter. Bei Hoch- spannungs-Trenn- und/oder Erdungsschaltern wird eine Strombahn getrennt an wenigstens einem Kontakt mit einer Trenn¬ strecke, welche z. B. von der angelegten Spannung abhängt. Ein elektrischer Kontakt umfasst eine Kontaktanordnung, welche wenigstens ein Kontaktelement und wenigstens ein Gegen- kontaktstück aufweist. High-voltage switching devices are used for switching high voltages and currents, in particular in the range of 70 to 800 kV. High-voltage switching devices are z. B. earthing switch and disconnector, in particular rotary disconnector, toggle disconnector, or single pivot disconnector. In high-voltage isolation and / or earthing switches, a current path is separated on at least one contact with a separation ¬ distance, which z. B. depends on the applied voltage. An electrical contact comprises a contact arrangement which has at least one contact element and at least one counter contact piece.
Im eingeschalteten bzw. elektrisch verbundenen Zustand des Hochspannungs-Schaltgerätes sind das wenigstens eine Kontakt¬ element und das wenigstens eine Gegenkontaktstück miteinander in elektrischem und insbesondere in mechanischem Kontakt. Im ausgeschalteten bzw. elektrisch getrennten Zustand des Hochspannungs-Schaltgerätes sind das wenigstens eine Kontaktele- ment und das wenigstens eine Gegenkontaktstück in einem Ab¬ stand zueinander angeordnet, bei welchem keine elektrischen Überschläge bzw. Lichtbögen auftreten. In the switched or electrically connected state of the high-voltage switching device, the at least one contact ¬ element and the at least one mating contact piece with each other in electrical and in particular in mechanical contact. In the off state and electrically separate the high-voltage switching device comprising a Kontaktele- are at least element and the at least one mating contact piece in a stand From ¬ one another, wherein no electrical flashover or arcing occur.
Beim Öffnen der Strombahn wird das wenigstens eine Kontakt- element relativ zum zugeordneten Gegenkontaktstück bewegt.When the current path is opened, the at least one contact element is moved relative to the associated mating contact piece.
Dabei kann das Gegenkontaktstück räumlich fixiert sein, d. h. als Festkontakt ausgebildet sein. Das wenigstens eine Kon- taktelement ist als Kontaktarm ausgebildet oder ist an einem Kontaktarm insbesondere elektrisch leitend befestigt. Der Kontaktarm wird über einen Antrieb und/oder ein Getriebe bewegt, insbesondere gesteuert, z. B. um sichtbar nach außen eine getrennte Strombahn und somit den ausgeschalteten Zustand darzustellen. Bei einem Drehtrennschalter erfolgt z. B. die Bewegung als Drehbewegung des Kontaktarms um eine insbe¬ sondere senkrechte Achse zur Längsachse des Kontaktarms. In this case, the mating contact piece may be spatially fixed, ie be designed as a fixed contact. The at least one con- Clock element is designed as a contact or is attached to a contact arm in particular electrically conductive. The contact is moved by a drive and / or a transmission, in particular controlled, for. B. to visibly outward represent a separate flow path and thus the off state. In a rotary disconnector z. B. the movement as a rotational movement of the contact arm to a particular special ¬ vertical axis to the longitudinal axis of the contact arm.
Durch die Bewegung des Kontaktarms wird beim Öffnen eine Trennstrecke erzeugt zwischen dem wenigstens einen Kontakt¬ element und dem zugeordneten Gegenkontaktstück. Ein elektrischer Kontakt und möglicher Stromfluss werden unterbunden. As a result of the movement of the contact arm, an isolating distance is generated during the opening between the at least one contact element and the associated mating contact piece . An electrical contact and possible current flow are prevented.
Beim Einschalten des Hochspannungs-Schaltgerätes , d. h. Ver¬ binden der Strombahn wird der Kontaktarm derart bewegt, insbesondere gedreht, dass das wenigstens eine Kontaktelement in mechanischen und elektrischen Kontakt mit dem zugeordneten Gegenkontaktstück gelangt. Eine elektrisch leitende Verbindung ist nach außen hin sichtbar hergestellt und das Hoch- spannungs-Schaltgerät ist eingeschaltet. Um bei einem Strom¬ fluss hohe elektrische Verluste aufgrund der hohen Spannungen und Ströme zu vermeiden, muss ein guter elektrischer Kontakt zwischen dem wenigstens einen Kontaktelement und dem zugeord¬ neten Gegenkontaktstück bestehen. Kurzschlussströme oder z. B. Wettereinflüsse wie Wind und Eisbildung können die Lage eines Kontaktarms zum Gegenkontaktstück verändern, und zu einer Verschlechterung des elektrischen Kontakts führen. Dabei können hohe elektrische Verluste auftreten oder es kann im Extremfall zu einer elektrischen, ungesteuerten Trennung des Hochspannungs-Schaltgerätes kommen . When switching on the high-voltage switching device, ie Ver ¬ bind the current path of the contact arm is moved in such a way, in particular rotated, that reaches the at least one contact element in mechanical and electrical contact with the associated mating contact piece. An electrically conductive connection is made visible to the outside and the high-voltage switchgear is switched on. In order to prevent high electrical losses due to the high voltages and currents at a current ¬ river, a good electrical contact between the at least one contact element and the mating contact piece zugeord ¬ Neten must exist. Short-circuit currents or z. B. Weather conditions such as wind and ice formation can change the position of a contact arm to the mating contact piece, and lead to a deterioration of the electrical contact. In this case, high electrical losses can occur or it can come in an extreme case to an electrical, uncontrolled separation of the high-voltage switching device.
Insbesondere bei rohrförmigen Kontaktelementen können ungesteuerte Bewegungen, insbesondere erzeugt durch Umweltein¬ flüsse und/oder Kurzschlussströme, zu einer Verringerung der Kontaktfläche zwischen Kontaktelement und Gegenkontaktstück im eingeschalteten Zustand des Hochspannungs-Schaltgerätes führen, bis hin zu einer Trennung des Kontaktes. Dadurch ist die Zuverlässigkeit des Hochspannungs-Schaltgerätes verrin¬ gert und es können Schäden im angeschlossenen Stromnetz und/oder hohe Verlustleistungen am Kontakt auftreten, welche hohe Kosten verursachen. In particular, in tubular contact elements uncontrolled movements, in particular generated by Umweltein ¬ flows and / or short-circuit currents, lead to a reduction in the contact area between the contact element and mating contact in the on state of the high-voltage switching device, up to a separation of the contact. This is the reliability of the high-voltage switching device verrin ¬ siege and it can damage the connected power grid and / or high power losses occur at the contact, which cause high costs.
Aufgabe der vorliegenden Erfindung ist die Vermeidung bzw. Reduzierung der zuvor beschriebenen Probleme. Insbesondere ist es Aufgabe, eine Kontaktanordnung für ein Hochspannungs- Schaltgerät sowie dessen Verwendung und Herstellung anzuge- ben, welche einen guten und sicheren, zeitlich stabilen Kontakt zwischen wenigstens einem Kontaktelement und einem Ge- genkontaktstück im eingeschalteten Zustand des Hochspannungs- Schaltgerätes ermöglicht, mit geringer Verlustleistung. Mit hohen Verlustleistungen verbundene Kosten sollen vermieden werden und Schäden in einem Stromnetz, welches an das Hochspannungs-Schaltgerät angeschlossen ist, sollen durch die er¬ findungsgemäße Kontaktanordnung vermieden werden. Die Kontaktanordnung soll einfach und kostengünstig herstellbar sein sowie einfach montierbar sein. Die Kontaktanordnung soll vielfältig einsetzbar sein, insbesondere durch Nutzung der Standardisierung .

In particular, it is an object to provide a contact arrangement for a high-voltage switchgear and its use and manufacture ben, which allows a good and safe, stable contact with time between at least one contact element and a GE genkontaktstück in the on state of the high-voltage switching device with less power dissipation. With high power losses associated costs are to be avoided and damage to a power grid, which is connected to the high voltage switching device should be he ¬-making proper contact arrangement avoided. The contact arrangement should be simple and inexpensive to produce and easy to install. The contact arrangement should be versatile, in particular by using standardization.
Die angegebene Aufgabe wird erfindungsgemäß durch eine Kon¬ taktanordnung für ein Hochspannungs-Schaltgerät mit den Merk- malen gemäß Patentanspruch 1 und/oder durch eine Verwendung der Kontaktanordnung gemäß Patentanspruch 11 sowie durch ein Verfahren zur Herstellung der Kontaktanordnung gemäß Patentanspruch 15 gelöst. Vorteilhafte Ausgestaltungen der erfindungsgemäßen Kontaktanordnung für ein Hochspannungs-Schalt- gerät und/oder der Verwendung der Kontaktanordnung sowie des Verfahrens zur Herstellung der Kontaktanordnung sind in den Unteransprüchen angegeben. Dabei sind Gegenstände der Hauptansprüche untereinander und mit Merkmalen von Unteransprüchen sowie Merkmale der Unteransprüche untereinander kombinierbar. The specified object is achieved by a con ¬ tact arrangement for a high-voltage switching device with the features according to claim 1 and / or by using the contact arrangement according to claim 11 and by a method for producing the contact arrangement according to claim 15. Advantageous embodiments of the contact arrangement according to the invention for a high-voltage switching device and / or the use of the contact arrangement and of the method for producing the contact arrangement are specified in the subclaims. In this case, objects of the main claims with each other and with features of subclaims and features of the dependent claims can be combined with each other.
Eine erfindungsgemäße Kontaktanordnung für ein Hochspannungs- Schaltgerät umfasst wenigstens einen beweglichen Kontaktarm mit wenigstens zwei Kontaktelementen zum elektrischen Kontaktieren eines Gegenkontaktstücks . Jeweils zwei Kontaktelemente sind einander gegenüberliegend angeordnet und bilden ein Kon¬ taktfinger-Paar aus. A contact arrangement according to the invention for a high-voltage switching device comprises at least one movable contact arm with at least two contact elements for electrically contacting a mating contact piece. In each case two contact elements are arranged opposite to each other and form a Kon ¬ tact finger pair.
Die Verwendung von wenigstens zwei sich gegenüberliegenden Kontaktelementen, welche ein Kontaktfinger-Paar ausbilden, ermöglicht einen zeitlich stabilen Kontakt zwischen den Kontaktelementen und dem Gegenkontaktstück im eingeschalteten Zustand des Hochspannungs-Schaltgerätes . Die Verlustleistung und damit verbundenen Kosten werden minimiert, und Schäden im Stromnetz, welches an das Hochspannungs-Schaltgerät ange¬ schlossen ist, werden vermieden. Die Kontaktelemente können U-förmig ausgebildet sein, wobei die Öffnungen der U-Form der Kontaktelemente eines Kontakt¬ finger-Paars insbesondere aufeinander zuweisend angeordnet sein können. Dadurch bilden die Kontaktelemente zwei Kontakt¬ flächen jeweils an den Enden der U-Form aus, sind mechanisch stabil und können in den Kontaktarm gut integriert bzw. an diesem mechanisch stabil und elektrisch gut leitend befestigt werden . The use of at least two opposing contact elements, which form a pair of contact fingers, enables stable contact over time between the contact elements and the mating contact piece in the switched-on state of the high-voltage switching device. The power loss and associated costs are minimized, and damage in the power grid, which is connected to the high-voltage switching device is ¬ avoided. The contact elements may be U-shaped, wherein the openings of the U-shape of the contact elements of a contact ¬ finger-pair can be arranged facing each other in particular. Characterized the contact elements form two contact surfaces ¬ respectively at the ends of the U-shape from, are mechanically stable and can be integrated well in the contact arm and fixed to a mechanically stable and highly electrically conductive.
Die Kontaktelemente können stabförmig ausgebildet sein, mit einem U-förmigen Querschnitt, wobei gegenüberliegende Schen¬ kel der U-Form die gleiche Länge L aufweisen. Bei einer Bewe¬ gung der gegenüberliegenden Kontaktelemente aufeinander zu, mit einem Gegenkontaktstück dazwischen angeordnet, kann das Gegenkontaktstück durch die U-förmigen Kontaktelemente mecha- nisch eingeklemmt werden, wodurch eine gute zeitliche und me¬ chanische Stabilität des elektrischen Kontakts zwischen dem Gegenkontaktstück und den Kontaktelementen erreicht wird. Dabei werden mit dem Gegenkontaktstück vier Kontaktflächen durch zwei U-förmigen Kontaktelemente ausgebildet, welche für einen guten elektrischen Kontakt mit minimierter Verlustleistung sorgen. Kanten und Ecken der Kontaktelemente können abgerundet sein, insbesondere alle Kanten und Ecken, jeweils mit einem Radius entsprechend der Lage auf dem Kontaktelement.

In a BEWE ¬ supply of the opposite contact elements towards one another, arranged with a counter-contact therebetween, the mating contact piece can be mechanically through the U-shaped contact elements are clamped cally, whereby a good temporal and me ¬ chanical stability of the electrical contact between the counter-contact piece and the contact elements is reached. In this case, four contact surfaces are formed by two U-shaped contact elements with the mating contact piece, which ensure good electrical contact with minimized power loss. Edges and corners of the contact elements may be rounded, in particular all edges and corners, each with a radius corresponding to the position on the contact element. This avoids or at least reduces corona phenomena and possible flashovers at edges and edges.
Der Kontaktarm kann wenigstens ein Profilstangen-Paar umfassen, welches wenigstens ein Kontaktfinger-Paar zumindest Teilweise umschließt. Dadurch wird das Kontaktfinger-Paar me- chanisch stabil gehalten. Mit einem Gegenkontaktstück zwischen dem Kontaktfinger-Paar angeordnet, kann im eingeschalteten Zustand des Hochspannungs-Schaltgerätes über das Pro- filstangen-Paar das Kontaktfinger-Paar an das Gegenkontaktstück angepresst werden, von entgegengesetzten Seiten her. Dabei ist das Gegenkontaktstück zwischen den Kontaktfingern des Kontaktfinger-Paares eingeklemmt und ein guter mechani¬ scher sowie elektrischer Kontakt besteht stabil zwischen dem Kontaktfinger-Paar und dem Gegenkontaktstück, wobei über das Kontaktfinger-Paar ein elektrischer Kontakt mit dem Profil- stangen-Paar, d. h. über den Kontaktarm hinweg besteht. The contact arm may comprise at least one pair of profile rods which at least partially surrounds at least one contact finger pair. As a result, the contact finger pair is kept mechanically stable. Arranged with a mating contact piece between the pair of contact fingers, in the switched-on state of the high-voltage switching device, the pair of contact fingers can be pressed against the mating contact piece, from opposite sides. In this case, the mating contact piece between the contact fingers of the contact finger pair is clamped and a good mechanical ¬ shear and electrical contact is stable between the contact finger pair and the mating contact piece, via the contact finger pair an electrical contact with the profile rod pair, ie exists over the contact arm.

Each contact finger pair 4 is in each case of a profile gene pair 11 encompasses or surrounds. The profiled rod pairs 11 with the associated contact finger pairs 4 form a contact arm 2 of the high-voltage switching device. Each contact ¬ finger-pair 4 consists of two contact elements 3, which are formed in profile, ie in cross-section U-shaped. The two U-shaped contact elements 3 are so arranged opposite each other ¬ one another, that the open sides of the U-form pointing to each other. Each profile bar pair 11 consists of two profile bars 6, which are also U-shaped in profile, ie in cross section. The two U-shaped profile bars 6 are arranged opposite each other such that the open sides of the U-shape face each other. The profile bars 6 have a greater width than the contact elements 3. In each profile bar 6, a contact element 3 is arranged at the end along the longitudinal axis of the profile bar 6 parallel to the profile bar 6, fitted into the U-shaped opening and z. B. via a spacer such. B. a washer 16 spaced from the profile bar 6 attached. The opening of the U-shape of the profile bar 6 and the opening of the U-shape of the ¬ orderly contact element 3, which is located in the profile bar 6, point in the same direction. The contact elements 3 are each on the associated Pro ¬ filstange 6 via fasteners 13, such. B. screws 14 with nuts 15, attached. Washers 16 may be arranged as a spacer between the contact element 3 and the profile bar 6, alternatively, not shown for simplicity in the figures, the contact elements 3 may also be arranged directly resting on the profile bar 6. In the embodiment of Figure 1, each contact ¬ element 3 each have two fastening elements 13, that is, two screws 14, each with a nut 15 and a UN washer to 16 between the contact element 3 and the Pro ¬ filstange 6, electrically conductively connected to the associated profile bar 6 mechanically fastened.

In Figur 2 ist die Kontaktanordnung 1 der Fig. 1 schematisch, in Seitenansicht dargestellt. Der Kontaktarm 2, mit den um- fassten Profilstangen 6 und Kontaktelementen 3, steht in elektrischem und mechanischem Kontakt mit einem plattenförmi- gen Kontaktelement 18 eines Gegenkontaktstücks 17. Die Kon¬ taktelemente 3 an den Profilstangen 6 bilden im Zusammenwirken mit dem Gegenkontaktstück 17 einen elektrischen Kontakt. Im geschlossenen Zustand des Hochspannungs-Schaltgerätes , d. h. bei geschlossenem Kontakt, wie in Figur 2 dargestellt ist, wird das plattenförmige Kontaktelement 18 des Gegenkon¬ taktstücks 17 von den Profilstangen-Paaren 11 mit den dazugehörigen Kontaktfinger-Paaren 4 eingeklemmt. Jeweils zwei Pro- filstangen 6 klemmen über die Kontaktelemente 3 das dazwischen angeordnete plattenförmige Kontaktelement 18 mechanisch stabil ein und bilden einen guten elektrischen Kontakt zwischen Gegenkontaktstück 17 und Kontaktarm 2 aus. Die Federelemente 19 pressen die Profilstangen 6 eines Profilstangen- Paares 11 und die daran befestigten Kontaktelemente 3 einesIn Figure 2, the contact assembly 1 of FIG. 1 is shown schematically, in side view. The contact arm 2, with the environmentally framed profile bars 6 and contact elements 3, is in electrical and mechanical contact with a plate-shaped contact element 18 of a counter-contact piece 17. The Kon ¬ clock elements 3 to the profile bars 6 form, in cooperation with the mating contact piece 17 an electrical Contact. In the closed state of the high-voltage switching device, ie when the contact is closed, as shown in Figure 2, the plate-shaped contact element 18 of Gegenkon ¬ contact piece 17 is clamped by the profiled rod pairs 11 with the associated contact finger pairs 4. In each case two profiled rods 6 mechanically clamp in a stable manner via the contact elements 3 the plate-shaped contact element 18 arranged therebetween and form a good electrical contact between the mating contact piece 17 and the contact arm 2. The spring elements 19 press the profile bars 6 of a pair of profile bars 11 and the contact elements 3 attached thereto
Kontaktfinger-Paares 4 zusammen, und klemmen somit das dazwi¬ schen befindliche plattenförmige Kontaktelement 18 zangenar¬ tig ein. Distanzelemente 20, beabstandet zu den Federelementen 19 und Kontaktelementen 3 entlang der Längsachse der Profilstangen 6 angeordnet, halten die Profilstangen 6 eines Profilstangen- Paares 11 auf gleichem Abstand, zeitlich stabil, mit Ausnahme des Endes der Profilstangen 6 mit den Kontaktelementen 3, welche durch die Federelemente 19 aufeinander zubewegt werden können und analog Blattfedern wirken. Im geöffneten Zustand des Hochspannungs-Schaltgerätes, bei dem das plattenförmige Kontaktelement 18 des Gegenkontaktstücks 17 beabstandet zum Kontaktarm 2 und den Kontaktelementen 3 angeordnet ist, können die Kontaktfinger-Paare 4 durch die Federelemente 19 am Ende des Kontaktarms 2 mehr zusammengepresst werden, d. h. die Kontaktelemente 3 eines Kontaktfinger-Paares 4 weisen ei¬ nen geringeren Abstand voneinander aus, insbesondere verglichen mit der Dicke des plattenförmigen Kontaktelements 18. Contact finger-pair 4 together and thus clamp the rule ¬ Between the seats located plate-shaped contact element 18 is a zangenar ¬ tig. Distance elements 20, spaced from the spring elements 19 and contact elements 3 along the longitudinal axis of the profile bars 6 are arranged, hold the profile bars 6 of a pair of profile rods 11 at the same distance, stable over time, with the exception of the end of the profile bars 6 with the contact elements 3, which by the Spring elements 19 can be moved towards each other and act analog leaf springs. In the open state of the high-voltage switching device, in which the plate-shaped Contact element 18 of the mating contact piece 17 spaced from the contact arm 2 and the contact elements 3 is arranged, the contact finger pairs 4 can be more compressed by the spring elements 19 at the end of the contact arm 2, ie the contact elements 3 of a contact finger pair 4 have ei ¬ NEN smaller distance from each other, in particular compared with the thickness of the plate-shaped contact element 18th
Z. B. durch Drehung des Kontaktarms 2 um eine senkrechte Ach- se zur Längsachse des Kontaktarms 2, wobei die senkrechte Achse in der Zeichenebene in Figur 2 liegt, wird das Hoch- spannungs-Schaltgerät von einem offenen in einen geschlosse¬ nen, d. h. kontaktierten Zustand bewegt. Das plattenförmige Kontaktelement 18 des Gegenkontaktstücks 17 wird zwischen die einander gegenüberliegenden Kontaktelemente 3 der Kontaktfinger-Paare 4 geschoben bzw. der Kontaktarm 2 schiebt die Kontaktelemente 3 über und unter das plattenförmige Kontaktele¬ ment 18. Der Anpressdruck der Federelemente 19 ergibt einen mechanisch und elektrisch stabilen Kontakt zwischen den Kon- taktelementen 3 des Kontaktarms 2 und dem plattenförmigen Kontaktelement 18 des Gegenkontaktstücks 17. For example, by rotation of the contact arm 2 about a vertical axis to the longitudinal axis of the contact arm 2, wherein the vertical axis lies in the drawing plane in Figure 2, the high-voltage switching device is moved from an open to a closed ¬ nen, ie contacted state , The plate-shaped contact element 18 of the mating contact piece 17 is pushed between the opposing contact elements 3 of the contact finger pairs 4 and the contact arm 2 pushes the contact elements 3 above and below the plate-shaped Kontaktele ¬ ment 18. The contact pressure of the spring elements 19 results in a mechanically and electrically stable Contact between the contact elements 3 of the contact arm 2 and the plate-shaped contact element 18 of the mating contact piece 17.
Zum Trennen des Kontaktes wird der Kontaktarm 2 in die entgegengesetzte Richtung um die senkrechte Achse gedreht. Das plattenförmige Kontaktelement 18 des Gegenkontaktstücks 17 wird aus dem Zwischenraum zwischen den einander gegenüberliegenden Kontaktelementen 3 der Kontaktfinger-Paare 4 geschoben bzw. der Kontaktarm 2 schiebt die Kontaktelemente 3 in eine Position beabstandet zum plattenförmigen Kontaktelement 18. Der Anpressdruck der Federelemente 19 bewegt die Kontaktele¬ menten 3 eines Kontaktfinger-Paares 4 weiter aufeinander zu und das Distanzelement 20 hält die Kontaktelementen 3 auf ei¬ nen Mindestabstand. In Figur 3 ist ein Kontaktelement 3 der Kontaktanordnung 1 der Figuren 1 und 2 im Detail schematisch in Aufsicht dargestellt. Das U-förmige Kontaktelement 3 ist mit der Öffnung der U-Form nach oben weisend gezeigt. Das Kontaktelement 3 ist schienen- bzw. stangenförmige ausgebildet, mit zwei To disconnect the contact, the contact arm 2 is rotated in the opposite direction about the vertical axis. The plate-shaped contact element 18 of the mating contact piece 17 is pushed out of the gap between the opposing contact elements 3 of the contact finger pairs 4 and the contact arm 2 pushes the contact elements 3 in a position spaced from the plate-shaped contact element 18. The contact pressure of the spring elements 19 moves the Kontaktele ¬ 3 of a contact finger pair 4 further toward each other and the spacer element 20 keeps the contact elements 3 at egg ¬ NEN minimum distance. In Figure 3, a contact element 3 of the contact arrangement 1 of Figures 1 and 2 is shown in detail schematically in plan view. The U-shaped contact element 3 is connected to the opening the U-shape pointing upwards. The contact element 3 is rail-shaped or rod-shaped, with two
Schenkeln 5 der U-Form auf der rechten und der linken Seite parallel zueinander sowie parallel und entlang der Längsachse des Kontaktelements 3. Die Ecken 10 können abgerundet sein, um Koronaerscheinungen an spitzen Formen zu vermeiden. Zwischen den Schenkeln 5 Mittig, jeweils zum Ende hin entlang der Längsachse des Kontaktelements 3, sind durchgehende Boh¬ rungen angeordnet, zum Befestigen des Kontaktelements 3 an der zugeordneten Profilstange 6 über Befestigungselemente 13, wie zuvor beschrieben. Legs 5 of the U-shape on the right and left sides parallel to each other and parallel and along the longitudinal axis of the contact element 3. The corners 10 may be rounded to avoid corona on pointed shapes. Between the legs 5 centrally, in each case towards the end along the longitudinal axis of the contact element 3, through Boh ¬ stanchions are arranged for fixing of the contact element 3 at the associated profile bar 6 by means of fastening elements 13, as previously described.
In Figur 4 ist das Kontaktelement 3 der Figur 3 im Detail schematisch im Querschnitt, senkrecht zur Längsachse darge¬ stellt. Die U-Form ist im Wesentlichen in Form eines in der Hälfte durchgeschnittenen Rechtecks, entlang einer Parallelen zu einer Rechteckseite geschnitten, mit abgerundeten Ecken und Kanten 7, 8, 9 ausgebildet. Die Schenkel 5 stehen senk¬ recht auf dem Mittelteil 21 des Kontaktelements 3, jeweils ein Schenkel 5 auf der rechten und linken Seite des Kontakt¬ elements 3 entlang des Querschnitts betrachtet. Die Schenkel 5 sind parallel zueinander angeordnet, als parallele Platten ausgebildet, mit abgerundeten Innen- und Außenkanten 7, 8 im Bereich des Übergangs zum Mittelteil 21 und abgerundeten Kanten 9 am oberen Schenkelende.

Mittig ange¬ ordnet, ist in Figur 4 im Querschnitt eine Bohrung 12 im Schnitt dargestellt, zum Durchführen von Befestigungselementen 13. In Figure 4, the contact element 3 of Figure 3 in detail is shown schematically in cross section, perpendicular to the longitudinal axis Darge ¬ . The U-shape is essentially cut in the form of a rectangle cut in half, cut along a parallel to a rectangle side, with rounded corners and edges 7, 8, 9.
