Description
Hochspannungs-Meßeinrichtung mit mehreren auf der Primärseite hintereinandergeschalteten Spannungswandlern Die Erfindung betrifft eine Hochspannungs-Meßeinx'ichtung mit mehreren auf der Primärseite hintereinandergeschalteten Spannungswandlern, deren einer sekundärseitig an Meßapparate angeschlossen ist. Es ist bereits vorgeschlagen worden, zur Erzielung einer gleichmäßigen Spannungsverteilung bei derartigen Einrichtungen die übrigen Wandler auf der Sekundärseite durch Widerstände zu belasten. Gemäß der Erfindung werden die Sekundärwicklungen derjenigen Spannungswandler,welche nicht an Meßapparäte angeschlossen sind, in sich kurzgeschlossen und der Belastungsstrom mittels Anzapfungen dieser Wicklungen geregelt.High-voltage measuring device with several connected in series on the primary side Voltage converters The invention relates to a high-voltage measuring device several voltage transformers connected in series on the primary side, whose one is connected to measuring equipment on the secondary side. It's already suggested has been used to achieve an even distribution of stress in such devices to load the remaining transducers on the secondary side with resistors. According to the Invention, the secondary windings of those voltage converters that are not are connected to measuring equipment, short-circuited and the load current regulated by means of taps on these windings.
Auf der Zeichnung ist eine Ausführungsform einer Anordnung nach der Erfindung schematisch dargestellt.In the drawing is an embodiment of an arrangement according to the Invention shown schematically.
Die Zeichnung zeigt eine Kaskade von drei Spannungswandlern, die zwischen eine Hochspannungsleitung x und Erde T geschaltet sind. Die Hochspannungswicklungen a1, a2, a3 sind in bekannter Weise in Reihe geschaltet. Diesen drei Wicklungen entsprechen die drei Sekundärwicklungen b1, b2, b3. Die Isolierungen zwischen Primär- und Sekundärwicklungen sind bei cl, c2 und c3 angedeutet und die Kerne jedes Transformators bei dl, d2 und d3. Die Mitten der Primär- und Sekundärwicklungen sind bei der dargestellten Ausführungsform an die Kerne der betreffenden Transformatoren angeschlossen.The drawing shows a cascade of three voltage converters, which are between a high-voltage line x and earth T are connected. The high voltage windings a1, a2, a3 are connected in series in a known manner. These three windings correspond the three secondary windings b1, b2, b3. The insulation between primary and secondary windings are indicated at cl, c2 and c3 and the cores of each transformer at dl, d2 and d3. The centers of the primary and secondary windings are in the one shown Embodiment connected to the cores of the transformers in question.
Die Sekundärwicklungen haben solchen Widerstand, daß sie in sich selbst geschlossen Kurzschlußströme bestimmter Werte hervorrufen. Vermittels verstellbarer Stromanschlüsse kann eine Regelung der Kurzschlußströme durch Änderung der kurzgeschlossenen Wicklungslängen herbeigeführt werden. An die Sekundärseite b3 des einen Stromwandlers sind die Meßapparate V und C angeschlossen.The secondary windings have such resistance that they in themselves closed cause short-circuit currents of certain values. By means of adjustable Power connections can regulate the short-circuit currents by changing the short-circuited Winding lengths are brought about. To the secondary side b3 of a current transformer the measuring devices V and C are connected.
