Description
Meßwandler für hohe Spannungen Der Aufbau von Transformatoren für hohe Spannungen macht deshalb Schwierigkeiten, weil der ein bestimmtes Potential besitzende Eisenkern überall von den auf verschiedenem Potential befindlichen Teilen der Hochvoltwicklung genügend weit entfernt sein muß.Measuring transformers for high voltages The construction of transformers for high tension causes difficulties because of a certain potential possessing iron cores everywhere of the parts at different potentials the high-voltage winding must be far enough away.
Es ist bereits bekannt, bei einem Transformator den Eisenkörper in voneinander elektrisch isolierte Eisenkörper zu unterteilen, welche die Wicklungen verschiedenen Potentials tragen, und dabei jede dicke Teilfuge in eine Anzahl dünner Teilfugen aufzulösen.It is already known that the iron body in a transformer is in from each other electrically insulated iron bodies to divide which the windings different potentials, and each thick parting line in a number thinner Dissolve butt joints.
Von diesen bekannten Anordnungen unterscheidet sich der Gegenstand der Erfindung dadurch, daß bei einem Meßwandler, bei dem die Hochspannungswicklung einen z. B. aus Scheibenspulen aufgebauten Zylinder bildet, zwischen dessen Enden die volle Spannung herrscht, an beiden Stirnflächen der Spulen mit den Wicklungsenden leitend verbundene Joche angeordnet sind, an die in den lichten Raum der Spule hineinragende Kernstümpfe angesetzt sind.The subject differs from these known arrangements of the invention in that in a transducer in which the high-voltage winding a z. B. formed from disc coils cylinder, between the ends full tension prevails on both end faces of the coils with the winding ends Conductively connected yokes are arranged on the protruding into the clear space of the coil Core stumps are attached.
Durch diese Bauart erhält man einen Spannungswandler, der bei einem Mindestaufwand an Isoliermaterial und Platzbedarf auch für die höchsten Spannungen brauchbar ist und dabei eine verhältnismäßig geringe Streuung besitzt, so daß die Meßfehler klein bleiben.This design gives you a voltage converter that works with a Minimum expenditure on insulation material and space requirement even for the highest voltages is useful and has a relatively low scatter, so that the Measurement errors remain small.
Man kann den neuen Meßwandler entweder so ausbilden, daß der Innenraum der Spule, abgesehen von den kurzen Kernstümpfen, frei von paramagnetischem Material ist, oder daß in dem Zwischenraum zwischen den beiden Kernstümpfen mit Isolierteilen abwechselnde Kernstücke angeordnet sind. Die Sekundärwicklung ordnet man zweckmäßig nicht über einem Luftspalt, sondern über einem Kernstück an, und zwar vorzugsweise auf dem das niedrigere Potential, im allgemeinen Erdpotential, führenden Kernstumpf. Wegen der verhältnismäßig großen Streuung muß ein solcher Wandler mit seiner Belastung zusammen geeicht werden. Die Streuungsverhältnisse werden verbessert, wenn man die einzelnen Kernstücke mit Hilfswicklungen versieht, die auf eine am besten einstellbare Belastung arbeiten. Diese Belastung kann aus Olimschen, induktiven oder kapazitiven Widerständen bestehen.You can either train the new transducer so that the interior of the coil, apart from the short core stumps, free of paramagnetic material is, or that in the space between the two core stumps with insulating parts alternating core pieces are arranged. The secondary winding is arranged appropriately not over an air gap, but over a core, preferably on the core stump carrying the lower potential, generally earth potential. Because of the relatively large spread, such a converter must with its load are calibrated together. The spread ratios are improved if the individual core pieces are provided with auxiliary windings that are best adjustable Work load. This load can be Olimian, inductive or capacitive Resistances exist.
In der Zeichnung sind zwei Ausführungsbeispiele der Erfindung dargestellt. Die HV-NVickhmg besteht in Abb. i aus hintereinandergeschalteten Scheibenspulen a, die von einem Isolierzylinder b getragen werden. 'Mit dem Anfang und Ende der Wicklung ist je ein Eisenjoch c verbunden, an das kurze, in die Wicklung hineinragende Kernstümpfe d angesetzt sind. Der untere geerdete Kernstumpf trägt die V-@@ icklung e.Two exemplary embodiments of the invention are shown in the drawing. The HV-NVickhmg in Fig. I consists of disc coils connected in series a, which are carried by an insulating cylinder b. 'With the beginning and end of the An iron yoke c is connected to each winding, to the short one that protrudes into the winding Core stumps d are attached. The lower grounded core stump carries the winding e.
In Abb. 2 sind in den freien Raum zwischen den Stümpfen d noch einzelne Eisenkernstücke f eingefügt, die durch zwischeneschaltete Isolier-t, teile n voneinander getrennt sind. Die einzeln E#n Kernstücke f sind durch Leitungen !a mit benachbarten Teilen der HV-Wicklung verbunden, um ein gleichmäßiges Spannungsgef-ille längs des Kerns zu erzwingen.In Fig. 2, in the free space between the stumps d nor individual iron core pieces inserted f, the t by zwischeneschaltete insulation, n parts are separated. The individual E # n core pieces f are connected to neighboring parts of the HV winding by lines! A in order to force a uniform voltage gradient along the core.
Will man den Spannungswandler in einer isolierenden Flüssigkeit, also z. B. in einer Ölfüllung, unterbringen, so wählt man als Behälter am besten einen solchen aus isolierendem Material, z. B. einen Hartpapierzylinder, dessen Boden und Deckel aus Metall bestehen und als Zuleitung dienen können.If you want the voltage converter in an insulating liquid, then z. B. in an oil filling, it is best to choose one as the container those made of insulating material, e.g. B. a hard paper cylinder, the bottom of which and cover are made of metal and can serve as a supply line.
