Description
Lufttransformator für hohe Spannungen mit Stabilisierungsringen in dem Raum zwischen Wicklungsende und Eisenjoch. Das Hauptpatent betrifft eine Einrichtung an Ein- oder Mehrphasen-Lufttransformatoren für hohe Spannungen zum Stabilisieren des elektrostatischen Feldes auf den über die Wicklung hinausragenden freien Isolierteilen der Hochspannungsschenkel, bei welcher im Raum zwischen Wicklungsende und Eisenjoch in einer der Spannungsverteilung entsprechenden Entfernung von dem Wicklungsende um den freien Isolierteil des Schenkels mindestens ein von Isolierorganen getragener aufgeschnittener Metallring angeordnet ist, welcher derart ausgebildet und verlegt ist, daß sich unter seinem Einfluß so- 1 wohl auf der Oberfläche des freien Isolier- j teils als auch um diesen herum eine möglichst gleichmäßige Verteilung des elektrostatischen Feldes einstellt.Air transformer for high voltages with stabilizing rings in the space between the end of the winding and the iron yoke. The main patent relates to a device on single or multi-phase air transformers for high voltages for stabilization of the electrostatic field on the free insulating parts protruding beyond the winding the high-voltage leg, in which in the space between the end of the winding and the iron yoke at a distance from the end of the winding that corresponds to the voltage distribution around the free insulating part of the leg at least one carried by insulating members cut open metal ring is arranged, which is designed and laid in such a way is that under its influence, 1 is well on the surface of the free insulating j in part as well as around this a uniform distribution of the electrostatic as possible Field.
Es kann bei dieser Einrichtung, namentlich bei Anwendung mehrerer Stabilisierungsringe, zweckmäßig sein, den Stabilisierungsring durch eine potentialaufdrückende elektrische Leitung auf einen seinem Abstand von der Wicklung entsprechenden Spannungswert zu bringen.It can be with this facility, especially when using several Stabilizing rings, it may be useful to replace the stabilizing ring with a potential-imposing one electrical line to a voltage value corresponding to its distance from the winding bring to.
Hierbei hat es sich als vorteilhaft erwiesen, in diese elektrische Leitung einen oder mehrere hohe Ohmsche Widerstände einzuschalten, die bezwecken, die Phasenlage der Spannung des Stabilisierungsringes auf einen bestimmten wählbaren Wert zu bringen, sowie bei -etwaigen überschlägen an dem Stabilisierungsring den Stromstoß zu begrenzen und Überspannungen bei Schwingungserscheinungen zu dämpfen.It has proven to be advantageous in this electrical To switch on one or more high ohmic resistances on the line, the purpose of which is to the phase position of the tension of the stabilization ring to a certain selectable Bring value, as well as any rollover on the stabilization ring Limit current surges and dampen overvoltages in the event of vibration phenomena.
Die Zeichnung veranschaulicht ein Ausführungsbeispiel des Erfindungsgegenstandes. Um den Eisenkern b ist die Niederspannungswicklung a angeordnet, welche von einem Luftmantel f umgeben ist, der durch den Isolerhohlzylinder g_ begrenzt wird. Letzterer trägt die Hochspannungswicklung h. Sie ist am Höchstspannungsende durch den Sprühring! abgeschlossen, von dem leichte Streifenentladungen längs des Isolierhohlzylinders g ausgehen.The drawing illustrates an embodiment of the subject matter of the invention. To the iron core b, the low-voltage winding a is arranged, which of a Air jacket f is surrounded by the insulating hollow cylinder g_ limited will. The latter carries the high-voltage winding h. She is at the high voltage end through the spray ring! completed, from which light stripe discharges along the Insulating hollow cylinder g go out.
Um das elektrostatische Feld auf dem zwischen dem oberen Ende der Hochspannungswicklung h und dem Eisenjoch liegenden freien Teil des IsolierhoWzylinders g und in der umgebenden Luft möglichst gleichmäßig zu gestalten, sind in dieseln Raume mehrere frei abstehende aufgeschnittene Metallringe r, r1 in geeignetem Abstande voneinander und von dem Höchstspannungsende der Wicklung h isoliert angeordnet, die auf ihrem Abstand von der Wicklung entsprechend abgestufte Spannungswerte gebracht sind. Angenommen, daß es sich um einen handelt, wird man ä. B. zwei Stabilisierungsringe r, r1 verwenden, von denen der der Wicklung h zunächst liegende r etwa auf 5oooo Volt, der andere, r1, auf iooooo Volt gegen den Hochspannungspol gebracht ist. Dies geschieht hier durch eine elektrische Verbindungsleitung s bzw. s1, die an eine der Spannung des Ringes entsprechende Anzapfstelle der Hochspanndngsvricklung h gelegt ist. In diese Verbindungsleitungen sind die eingangs benannten hohen Ohmschen Widerstände w bzw. w1 eingeschaltet, deren Zweck oben angegeben ist.To get the electrostatic field on the between the top of the High-voltage winding h and the iron yoke lying free part of the insulating hoW cylinder g and in the surrounding air as evenly as possible are in diesels Space several freely protruding cut metal rings r, r1 at a suitable distance arranged isolated from each other and from the extra-high voltage end of the winding h, which brought voltage values correspondingly graded on their distance from the winding are. Assuming that it is one, one becomes, for example, two stabilizing rings Use r, r1, of which the r of the winding h lying next to about 5oooo Volt, the other, r1, is brought to iooooo volts against the high voltage pole. this happens here through an electrical connection line s or s1, which is connected to a the high voltage winding tapping point corresponding to the tension of the ring h is laid. The high ohmic lines mentioned at the beginning are in these connecting lines Resistors w and w1 turned on, the purpose of which is given above.
Direkt mit dem Eisenjoch steht noch ein dachförmiger Stabilisierungsring t in Verbindung, der, weit ausholend und nach außen reichend, Gestellpotential hat und ebenfalls zur Vergleichmäßigung der Feldverteilung beiträgt.Directly with the iron yoke is a roof-shaped stabilizing ring t in connection, which, far reaching and reaching outwards, has frame potential and also contributes to the equalization of the field distribution.
