Description
Die Erfindung betrifft eine gekapselte
Spannungswandleranordnung für Schaltanlagen mit
mehreren Anlagenfeldern, die entlang von nebeneinander
verlaufenden Anlagenachsen angeordnet sind, gemäß dem
Oberbegriff des Patentanspruchs 1.The invention relates to an encapsulated
Voltage converter arrangement for switchgear with
several plant fields that run alongside each other
extending system axes are arranged, according to
Preamble of
Bei Schaltanlagen mit mehreren Anlagenfeldern, die nebeneinander angeordnet sind, kann der Abstand zwischen den nebeneinander verlaufenden Anlagenachsen einen durch den Durchmesser des Wandlergehäuses bestimmten Mindestabstand nicht unterschreiten. Dieser Abstand soll aber möglichst klein sein, damit Raum für zusätzliche Elemente in der Schaltanlage vorhanden ist. Daraus ergibt sich die Forderung nach zunehmend kompakter werdender Bauweise der Schaltanlagen und kleiner werdenden Gehäusedurchmessern für die Wandlergehäuse. Andererseits wächst mit kompakter werdenden Gehäusen das Risiko des Durchschlagens benachbarter Spannungswandler, insbesondere bei Hochspannungsschaltanlagen mit bis zu 145 kV.In switchgear with several system fields, the are arranged side by side, the distance between the plant axes running side by side one by the diameter of the converter housing do not fall below a certain minimum distance. This But distance should be as small as possible, so that there is room for additional elements are present in the switchgear. Hence the demand for increasing compact design of switchgear and smaller and smaller housing diameters for the Converter housing. On the other hand, grows with more compact exposing housings the risk of breakdown Adjacent voltage converter, especially at High-voltage switchgear with up to 145 kV.
Aus der DE-U-9 209 167 ist eine gekapselte Spannungswandleranordnung bekannt, bei der drei im Schnitt runde oder längliche Gehäuse für jeweils einen Spannungswandler nebeneinander angeordnet sind. Wenn jeder Spannungswandler sein eigenes Gehäuse hat, gibt es zwar keine besonderen Probleme mit der gegenseitigen elektrischen Isolierung, aber dafür ist die Anordnung auch nicht mehrphasig ausgelegt. Andererseits wäre der Aufbau einer mehrphasigen Anordnung nicht mehr kompakt, wenn sie nach dem Vorbild dieser Veröffentlichung mit jeweils einem separaten Gehäuse für jeden Spannungswandler ausgestalten wäre. DE-U-9 209 167 is an encapsulated one Voltage converter arrangement known in the three in section round or elongated housing for one Voltage transformers are arranged side by side. If each voltage converter has its own housing while there are no particular problems with each other electrical insulation, but that's the arrangement also not designed multi-phase. On the other hand, that would be Building a multi-phase arrangement is no longer compact, if along the lines of this release a separate housing for each Voltage converter would be designed.
Aus den Patent Abstracts of Japan Vol. 5, Nr. 192, JP-A-56 114308 ist bekannt, in einem einzigen Gehäuse drei Spannungswandler unterzubringen. In einem ersten Ausführungsbeispiel sind die drei Spannungswandler in einer Reihe nebeneinander angeordnet, wobei die Kernachsen der Magnetkerne quer zur Längsachse eines im Schnitt rechteckigen Gehäuses ausgerichtet und in Längsrichtung hintereinander angeordnet sind. Dabei kommen sich die Spulen sehr nahe, so daß die Durchschlagsfestigkeit beeinträchtigt sein kann. In einem zweiten Ausführungsbeispiel sind die Kernachsen wiederum parallel zueinander ausgerichtet, aber die Spannungswandler sind in einer Dreiecks formation in einem im Schnitt kreisrunden Gehäuse untergebracht. Dabei ist die Gehäusebreite (= Durchmesser) wieder relativ groß.From Patent Abstracts of Japan Vol. 5, No. 192, JP-A-56 114308 is known to have three in a single housing To accommodate voltage transformers. In a first The three voltage converters in FIG a row arranged side by side, the Core axes of the magnetic cores transverse to the longitudinal axis of an im Section rectangular case aligned and in Are arranged one behind the other in the longitudinal direction. Here the coils come very close so that the Dielectric strength can be impaired. In a second embodiment are the core axes again aligned parallel to each other, but the Voltage transformers are in a triangular formation housed in an average circular housing. The housing width (= diameter) is again relatively large.
Aus der DE-C-0 576 081 ist eine Spannungswandleranordnung mit drei in einer Reihe angeordneten Spannungswandlern bekannt, bei der ebenfalls die Kernachsen der Magnetkerne quer zur Längsachse eines länglichen Gehäuses ausgerichtet und in Längsrichtung hintereinander angeordnet sind. Außerdem sind die Kerne durch seitliche, in Längsrichtung verlaufende Kernschenkel miteinander verbunden. Aber auch hier ist der Abstand zwischen den Spulen sehr gering, so daß die Spannungsfestigkeit beeinträchtigt sein kann.DE-C-0 576 081 is a Voltage transformer arrangement with three in a row arranged voltage transformers known in the also the core axes of the magnetic cores transverse to Longitudinal axis of an elongated housing aligned and are arranged one behind the other in the longitudinal direction. In addition, the cores are by side, in Core legs extending in the longitudinal direction with one another connected. But here too is the distance between the Coils very low, so that the dielectric strength may be affected.
Der Erfindung liegt die Aufgabe zugrunde, eine gekapselte Spannungswandleranordnung für Schaltanlagen mit mehreren Anlagenfeldern anzugeben, die eine geringe Gehäusebreite aufweist und trotzdem einen ausreichenden Abstand zwischen den spannungsführenden Bauteilen gewährleistet, und eine Schaltanlage anzugeben mit diesen gekapselten Spannungswandleranordnungen.The invention has for its object a encapsulated voltage transformer arrangement for switchgear to indicate with several plant fields, which a small Has housing width and still a sufficient Distance between the live components guaranteed, and to specify a switchgear these encapsulated voltage converter arrangements.
Eine Lösung der Aufgabe ergibt sich aus dem
kennzeichnenden Teil des Patentanspruchs 1. Im Prinzip
besteht die erfindungsgemäße Lösung darin, daß die
Spannungswandler zwar auch parallel zueinander
ausgerichtet, aber versetzt zueinander angeordnet sind.
Dabei sind die Kerne des ersten und des dritten
Spannungswandlers seitlich links neben der
Gehäuselängsachse und der Kern des mittleren
Spannungswandlers rechts daneben versetzt, so daß sich
die nebeneinander liegenden freien Enden der Kerne in
Längsrichtung überlappen. Diese Anordnung nutzt sowohl
die Gehäuselänge als auch die Gehäusebreite optimal
aus, ohne daß die auf den Kernen angeordneten Spulen zu
nahe an die Gehäusewände zu liegen kämen. Auch die
Abstände der Spulen untereinander sind groß genug, um
Spannungsüberschläge zu verhindern. Daraus ergibt sich
der Vorteil, daß bei Schaltanlagen mit mehreren
Anlagenfeldern auch mehrere Wandlergehäuse in einem
kürzeren Abstand zueinander angeordnet werden können.
Die Schaltanlagen werden dadurch kompakter, ohne daß
Abstriche hinsichtlich der Spannungsfestigkeit gemacht
werden müßten.A solution to the problem arises from the
characterizing part of
Für ein weniger länglich ausgebildetes Wandlergehäuse wird eine andere Lösung empfohlen, bei der drei Spannungswandler in Sternform mit radial voneinander wegweisenden Kernachsen angeordnet sind, wobei die Kernachse eines der Spannungswandler parallel zur Gehäuselängsachse ausgerichtet ist und die beiden anderen Kernachsen jeweils einen Winkel von mehr als 120° zur ersten Kernachse aufweisen. Obwohl diese Anordnung nicht sehr stark von der bekannten Anordnung mit drei 120°-Winkeln zwischen den Kernachsen abweicht, ergibt sich trotzdem ein wesentlicher Vorteil im Hinblick auf die verringerte Gehäusebreite.For a less elongated converter housing another solution is recommended, where three Voltage transformers in star shape with radial to each other pioneering core axes are arranged, the Core axis of one of the voltage transformers parallel to Longitudinal axis of the housing is aligned and the two other core axes each an angle of more than Have 120 ° to the first core axis. Although these Arrangement not very much from the known arrangement deviates with three 120 ° angles between the core axes, there is nevertheless a significant advantage in With regard to the reduced housing width.
In einer ersten vorteilhaften Ausgestaltung ist das Wandlergehäuse im Schnitt elliptisch, wobei vier rechteckig angeordnete und abgerundete Ecken angedeutet sind. Diese Gehäuseform empfielt sich insbesondere, wenn der Innenraum des Wandlergehäuses mit einem Isoliergas, beispielsweise Schwefelhexafluorid, unter hohem Druck gefüllt werden soll. Die gebogenen Gehäusewände benötigen nur eine geringe Wandstärke. In einer weiteren Ausgestaltungsform des Wandlergehäuses sind zusätzlich die Längsseiten abgeflacht. Diese Gehäuseform ist insbesondere dann vorteilhaft, wenn die Gehäuselänge nicht sehr viel größer ist als die Gehäusebreite.In a first advantageous embodiment, this is Transducer housing elliptical in section, four Rectangularly arranged and rounded corners indicated are. This form of housing is particularly recommended if the interior of the converter housing with a Insulating gas, for example sulfur hexafluoride, under high pressure to be filled. The curved Housing walls only require a small wall thickness. In a further embodiment of the converter housing the long sides are also flattened. This Housing shape is particularly advantageous if the Case length is not very much larger than that Case width.
In einer weiteren erfindungsgemäßen Lösung der gestellten Aufgabe ist die Gehäuselängsachse des Wandlergehäuses im wesentlichen senkrecht zu einer durch die Anlagenachsen bestimmten Ebene ausgerichtet und die Spannungswandler sind mit ihren Kernachsen quer zur Gehäuselängsachse ausgerichtet und in Längsrichtung übereinander angeordnet, wobei die Kerne durch zwei seitliche, in Längsrichtung verlaufende Kernschenkel einstückig miteinander verbunden sind.In a further solution according to the invention The task is the longitudinal axis of the housing Transducer housing substantially perpendicular to one level determined by the system axes and the voltage transformers are transverse with their core axes aligned to the longitudinal axis of the housing and in the longitudinal direction arranged one above the other, the cores being separated by two lateral, longitudinal core legs are integrally connected.
In der Praxis steht das Wandlergehäuse mit seiner Gehäuselängsachse bei dieser Ausführungsform vertikal, so daß sie für Schaltanlagen empfohlen werden kann, deren Bauraum in der Breite, d.h. quer zu den Anlagenachsen eingeschränkt ist, wo jedoch vertikal nach oben genügend Bauraum zur Verfügung steht.In practice, the converter housing with its In this embodiment, the longitudinal axis of the housing is vertical, so that it can be recommended for switchgear, their installation space in width, i.e. across to the Plant axes is restricted, however, where vertical enough space is available upwards.
Gegenstand der Erfindung ist ferner auch eine Schaltanlage mit erfindungsgemäß ausgestalteten Spannungswandleranordnungen. Dabei sind in einer besonders einfachen ersten Ausgestaltungsform der Schaltanlage die Wandlergehäuse in Querrichtung zu den Anlagenachsen einfach nebeneinander in Reihe angeordnet. Schon eine derartige Anordnung ist wegen der erfindungsgemäßen Ausgestaltung der Spannungswandleranordnungen kompakter als bekannte Schaltanlagen.The invention also relates to a Switchgear designed according to the invention Voltage converter arrangements. Are in one particularly simple first embodiment of the Switchgear the converter housing in the transverse direction to the Plant axes simply side by side in a row arranged. Such an arrangement is already due the inventive design of the Voltage converter arrangements more compact than known ones Switchgear.

Spannungswandler 2, 3, 4 angeordnet, die jeweils einen
Kern 5 und eine Spule 6 aufweisen. Das Wandlergehäuse 1
ist im wesentlichen elliptisch ausgestaltet und hat
vier rechteckig angeordnete und abgerundete Ecken 7.
Zwei Seitenwände 8 sind gebogen ausgeführt und
erstrecken sich im wesentlichen in Richtung einer

Die Spannungswandler 2, 3, 4 sind in länglicher
Formation in Richtung der Gehäuselängsachse 9
hintereinander angeordnet, wobei die Kernachsen 10,
11, 12 der Kerne 5 parallel zur Gehäuselängsachse 9
liegen. Die Kernachsen 10 und 12 eines ersten und eines
dritten Kerns 5 sind seitlich nach links gegenüber der
Gehäuselängsachse 9 verschoben. Ein zweiter mittlerer
Kern 5 mit der Kernachse 11 ist seitlich rechts
gegenüber der Gehäuselängsachse 9 verschoben. Die
freien Enden 13, 14, 15, 16 der Kerne 5 liegen
nebeneinander und überlappen sich in Längsrichtung.The
Bei der in Fig. 2 dargestellten Anordnung sind die
Kernachsen 10, 11, 12 quer zur Gehäuselängsachse 9
ausgerichtet und die Spannungswandler 2, 3, 4 wiederum
in Längsrichtung hintereinander angeordnet. Die drei
Kerne 5 sind durch zwei seitliche, parallel zur
Gehäuselängsachse 9 verlaufende Kernschenkel 17, 18
einstückig miteinander verbunden.In the arrangement shown in Fig. 2, the
Core axes 10, 11, 12 transverse to the
Fig. 3 zeigt ein Wandlergehäuse 19, bei dem die
Gehäuselänge l nicht sehr viel größer als die
Gehäusebreite b ist. Darüber hinaus ist das
Wandlergehäuse 19 an seinen Längsseiten abgeflacht, so
daß zwei gerade, parallel verlaufende Seitenwände 20
entstehen. Die drei Spannungswandler 2, 3, 4 sind
sternförmig mit radialen Kernachsen 10, 11, 12
angeordnet, wobei die Kernachse 10 eines ersten
Spannungswandlers 2 parallel zur Gehäuselängsachse 9
ausgerichtet ist und mit dieser zusammenfällt. Die
beiden anderen Kernachsen 11, 12 der beiden anderen
Spannungswandler 3, 4 weisen jeweils zur ersten
Kernachse 10 einen Winkel W von mehr als 120° auf.Fig. 3 shows a
Das in Fig. 4 dargestellte Wandlergehäuse 21 ist im
wesentlichen zylinderförmig, wobei wiederum die
Gehäuselänge l größer als die dem Zylinderdurchmesser
entsprechende Gehäusebreite b ist. Auch hier sind die
Spannungswandler 2, 3, 4 mit ihren Kernachsen 10, 11,
12 quer zur Gehäuselängsachse 9 angeordnet, wobei die
Kerne 5 durch zwei seitliche, parallel zur
Gehäuselängsachse 9 verlaufende Kernschenkel 17, 18
einstückig miteinander verbunden sind. Man erkennt in
der Fig. 4 auch drei elektrische Leiter 22, mittels
derer die elektrische Spannung an die drei Spulen 6
herangeführt wird.The
In den Fig. 5 bis 7 ist die Anordnung der
erfindungsgemäßen Wandlergehäuse 1, 19, 21 in
elektrischen Schaltanlagen dargestellt. Eine derartige
Schaltanlage besitzt drei Anlagenfeldern, die entlang
von parallel zueinander verlaufenden Anlagenachsen A,
B, C angeordnet sind. Bei den in den Fig. 5 und 6
dargestellten Anordnungen ist die jeweilige
Gehäuselängsachse der Wandlergehäuse 1, 9, 21 parallel
zu den Anlagenachsen A, B, C ausgerichtet. Wegen der
geringen Gehäusebreite b können die Abstände t zwischen
den Anlagenachsen A, B, C vorteilhaft klein gehalten
sein. Dabei sind die Wandlergehäuse 1, 19 quer zu den
Anlagenachsen A, B, C in einfacher Reihe nebeneinander
angeordnet.5 to 7, the arrangement of the
Bei einer weiteren, in Fig. 7 dargestellten
Ausführungsform der Erfindung, sind die
Gehäuselängsachsen 9 der Wandlergehäuse 21 senkrecht zu
einer durch die Anlagenachsen A, B, C bestimmten Ebene
ausgerichtet. In Fig. 7 entspricht diese Ebene der
Papierebene, auf der die Gehäuselängsachsen 9 senkrecht
stehen. Das zylindrische Wandlergehäuse 21 ragt dann
vertikal nach oben. Der Zylinderdurchmesser des
Wandlergehäuses 21 bestimmt hier die Gehäusebreite b,
die wiederum vorteilhaft klein ausfällt, da bei dieser
erfindungsgemäßen Anordnung innerhalb des kreisförmigen
Querschnitts nur ein Spannungswandler untergebracht
werden muß, da die drei Spannungswandler 2, 3, 4
übereinander in Richtung der Zylinderlängsachse
angeordnet sind. Im Gegensatz dazu sind bei dem Stand
der Technik die drei Spannungswandler innerhalb des
kreisförmigen Gehäusequerschnitts nebeneinander
sternförmig angeordnet, woraus sich ein größerer
Gehäusedurchmesser und damit eine größere
Gehäusebreite b ergibt. In another, shown in Fig. 7
