Description

Hochspannungstransformator mit primärer Speisung der Glieder höherer Spannungsstufen durch in einer niederen Spannungsstufe induzierte, in der nächsthöheren Spannungsstufe induzierende Hilfswicklungen Die Erfindung bezieht sich auf einen Hochspannungstransformator mit stufenweiser Erreichung der Höchstspannung unter Herabsetzung der Spannungsdifferenzen zwischen der Hochspannungswicklung einerseits und der Niederspannungswicklung bzw. den Gehäusen andererseits durch stufenweise angeordnete Hilfstransformatoren, von denen jeder immer zur Speisung der primären Wicklung der nächsthöheren Spannungsstufe dient, während der zu transformierende Urstrom lediglich dem Gliedtransformator der ersten Spannungsstufe zugeführt wird. Fach dein Patent d3oo8z geschieht die primäre Speisung der Gliedtransformatoren der höheren (zweiten und folgenden) Spannungsstufen durch je miteinander, doch nicht mit den sonstigen Wicklungen leitend verbundene Spulenpaare, .von denen die eine Spule als induzierte Hilfswicklung dem ersten (unteren) Gliedtransformator, die andere Spule als induzierendeNilfswicklungdemnächsthöheren Gliedtransformator angehört. Bei der praktischen Durchführung hat sich herausgestellt, daß in sehr vielen Fällen bei geeigneten Stromstärken die unter sich verbundenen Spulenpaare, welche zur primären Speisung des Gliedtransformators der nächsthöheren Spannungsstufe aus der unteren Stufe dienen, in einfacher Weise ersetzt werden können durch ein in sich zurücklaufendes Metallband, welches je einen Schenkel der zwei aufeinanderfolgenden Spannungsstufen zugehörigen Kerne umschlingt, wie es in ähnlicher Weise z. B. bei Schweißtransformatoren vorkommt. Die Anwendung dieser Anordnung auf den gestaffelten Hochspannungstransformator ergibt eine besonders einfache fertigungstechnisch und wirtschaftlich vorteilhafte Bauart für Transformatoren, bei denen sich die Kerne benachbarter Spannungsstufen gleichlaufend gegenüberliegen.High-voltage transformer with primary supply of the higher limbs Voltage levels induced in a lower voltage level and in the next higher one Voltage level inducing auxiliary windings The invention relates to a High voltage transformer with gradual reaching of the maximum voltage below Reduction of the voltage differences between the high-voltage winding on the one hand and the low-voltage winding or the housings on the other hand by stepwise arranged auxiliary transformers, each of which is always used to feed the primary Winding of the next higher voltage level is used, while the one to be transformed Urstrom is only fed to the link transformer of the first voltage level. Subject your patent d3oo8z is the primary supply of the link transformers of the higher (second and following) levels of tension through each other, but not Coil pairs conductively connected to the other windings, one of which Coil as an induced auxiliary winding of the first (lower) link transformer, the other coil as inducing auxiliary winding belongs to the next higher link transformer. In practice it has been found that in very many cases with suitable currents, the interconnected pairs of coils, which are the primary Supply of the link transformer of the next higher voltage level from the lower one Serve stage, can be replaced in a simple manner by a running back in itself Metal band, which has one leg of each of the two successive tension levels associated cores, as it is in a similar manner z. B. in welding transformers occurs. The application of this arrangement to the staggered high voltage transformer results in a particularly simple manufacturing technology and economically advantageous Design for transformers in which the cores of adjacent voltage levels are located facing in the same direction.

In Abb. i ist das Schema eines Stufentransformators mit der erfindungsgemäßen Anordnung dargestellt. K1, K2, K3 sind die Kerne der drei Gliedtransformatoren, die von der ersten Primärwicklung P aus gespeist werden. S', S2, S3 sind die Sekundärwicklungen. Zur Vermittlung der primären Speisung der oberen Spannungsstufen von der untersten Stufe aus dienen die in sich zurücklaufenden Kupferbänder 3111 und 1T', welche je einen Schenkel der zu zwei benachbarten Spannungsstufen gehörenden Kerne umschlingen. Zur leitenden Verbindung der hintereinandergeschalteten Sekundärwicklungen dient nach der Zeichnung zwischen der ersten und zweiten Spannungsstufe ein besonderer Draht i, der die Sekundärwicklung der ersten Stufe mit dem seinerseits mit der Sekundärwicklung der zweiten Stufe leitend verbundenen Kern K-' verbindet. Zwischen der zweiten und dritten Stufe aber übernimmt laut Zeichnung das Band 1M2 die entsprechende Verbindung, indem es einerseits mit der Sekundärwicklung S2, andererseits mit dem Kern K3 metallisch verbunden ist. In diesem Falle überlagern sich natürlich in dem Kupferband zwei Ströme, nämlich der Hochspannungsstrom und der Übertragungsstrom zur primären Speisung des nächstoberen Glieds, .was aber bei zureichender Ouerschnittsbemessung des Metallbandes durchaus zulässig ist.In Fig. I is the scheme of a step transformer with the invention Arrangement shown. K1, K2, K3 are the cores of the three link transformers, which are fed from the first primary winding P. S ', S2, S3 are the secondary windings. To convey the primary supply of the upper voltage levels from the lowest Step off are the copper strips 3111 and 1T 'running back in themselves, which are each wrap around one leg of the cores belonging to two adjacent voltage levels. For the conductive connection of the secondary windings connected in series serves according to the drawing between the first and second voltage level a special one Wire i, which connects the secondary winding of the first stage with that in turn with the secondary winding the second stage conductively connected core K- 'connects. Between the second and third stage, however, according to the drawing, the band 1M2 takes over the corresponding connection, by being metallic on the one hand with the secondary winding S2, on the other hand with the core K3 connected is. In this case, of course, two overlap in the copper band Currents, namely the high-voltage current and the transmission current for the primary supply of the next upper link, but what if the cross-section of the metal band is adequate is quite permissible.

Abb. 2 stellt eine ohne besondere Erläuterung verständliche Ausführungsform mit offenen Kernen KI, K2, K3 und Kraftlinienrückschluß durch die Luft dar. Die Bänder 1111, M2 sind konzentrisch zu den Sekundärwicklungen S1, S=, S3 angeordnet; zur primären Speisung der zweiten Spannungsstufe sind zwei Bänder 1111- vorhanden. Die Anordnung zweier Bänder zwischen dem ersten Gliedtransformator KI und dem zweiten Gliedtransformator K2 hat zunächst den Vorteil, daß die Übertragung der Leistung für die Glieder der beiden höheren Spannungsstufen auf zwei parallel geschaltete Übertragungsglieder verteilt wird. Wichtiger ist die Verminderung der Streuung durch die konzentrische Anordnung der beiden Bänder i111, und dieser Vorteil gilt auch für die Übertragung zur dritten Stufe durch das zwischen den beiden Bändern Ml angeordnete Band 1b72. Die offenen Kerne K1, K2, K3 sind nur beispielsweise gezeichnet; in der Regel wird man besser geschlossene Kerne anordnen.FIG. 2 shows an embodiment which can be understood without any particular explanation with open cores KI, K2, K3 and line of force inference through the air. The Ribbons 1111, M2 are arranged concentrically to the secondary windings S1, S =, S3; For the primary supply of the second voltage stage there are two ribbons 1111-. The arrangement of two bands between the first link transformer KI and the second Section transformer K2 initially has the advantage that the transmission of power for the links of the two higher voltage levels to two connected in parallel Transmission links is distributed. It is more important to reduce the spread through the concentric arrangement of the two bands i111, and this advantage also applies for the transfer to the third stage through the one arranged between the two belts Ml Volume 1b72. The open cores K1, K2, K3 are shown only as an example; in the As a rule, it is better to arrange closed cores.
