Description
2 n-polige (n > 1) Hochspannungs-Gleichstrommaschine mit mehreren voneinander getrennten Stromwenderwicklungen. Bekanntlich bereitet die Ankerisolation bei Gleichstrom-Hochspannungsmaschinen große Schwierigkeiten, da die sich überkreuzenden Wickelköpfe die größte Spannung gegeneinander besitzen. Zur Vermeidung dieses Übelstandes kann man die Maschine so -unterteilen, daß zur Erzeugung einrer gegebenen Gleichstromspannung mehrere Maschinen hintereinandergeschaltet werden, wobei die einzelnen Anker oder Maschinen von der Erde isoliert aufgestellt sein müssen. Dasselbe Ziel läßt sich erfindungsgemäß einfacher dadurch erreichen, daß man einen vier- oder mehrpoligen Gleichstromerzeuger verwendet, bei deni je zwei nebeneinanderliegende Pole eine gemeinsame Ankerwicklung besitzen, die zu einem besonderen Stromwender geführt ist. Man erreicht dadurch, daß die äußerlich wie eine einzige Maschine aussehendeDynamo in mehrere unterteilt ist und dieselben Vorteile wie bei Hnntereinanderschaltung mehrerer Maschineneinheiten 'erzielt werden bei Vermeidung der;#lsolattansschwierngkeiten.2 n-pole (n> 1) high-voltage direct current machine with several mutually separate commutator windings. As is known, the anchor insulation prepares with direct current high-voltage machines great difficulties, since they cross each other Winding heads have the greatest tension against each other. To avoid this inconvenience the machine can be subdivided so that it can generate a given direct current voltage several machines can be connected in series, with the individual armature or Machines must be set up isolated from the earth. The same goal can be achieved According to the invention, easier to achieve by having a four-pole or multi-pole DC generator is used, two adjacent poles each with one have a common armature winding, which is led to a special commutator. This makes the dynamo look like a single machine is divided into several and have the same advantages as with interconnection multiple machine units' can be achieved while avoiding the; #lsolattans Difficulties.
Die Erfin_ dung verwendet zusammenfassend gesagt die Erkenntnis, daß es für die Wirkungsweise eines aus mehreren Einzelmaschinen gebildeten Gleichstromerzeugers gleichgültig ist, wie die einzelnen Maschinen zueinander angeordnet sind - ob sie in Richtung der Drehachse oder in Umdrehungsrichtung aufeinanderfolgen -, wenn nur die Schaltung der Stromwender in gleicher Weise erfolgt, z. B. Schaltung in Reihe zur Erzeugung höherer Spannung.In summary, the invention uses the knowledge that it for the mode of operation of a direct current generator made up of several individual machines It does not matter how the individual machines are arranged in relation to one another - whether they in the direction of the axis of rotation or in the direction of rotation - if only the switching of the commutator takes place in the same way, z. B. Connection in series to generate higher voltage.
Durch die Erfindung wird vermieden, daß benachbarte Wicklungen zu starke Spannung gegeneinander haben.The invention prevents adjacent windings from becoming too have strong tension against each other.
Die Abbildungen stellen als Ausführungsbeispiel eine vierpolige Dynamomaschine dar. In Abb. r ist m das Magnetgestell. Eine (durch stärkere Striche hervorgehobene) Hälfte w der Ankerwicklung steht mit einem Stromwender s in Verbindung. Die beiden Bürsten b sind so angebracht, daß sie an Stellen größter Spannungsdifferenz des Stromwenders s den durch die eine Wicklungshälfte erzeugten Strom abnehmen. Auf der anderen Ankerhälfte sind nur die Spulenköpfe k reit ihren (dünn gezeichneten) Verbindungen sichtbar. Sie führen zu einem zweiten Stromwender, der auf der entgegengesetzten Seite angebracht sein kann, wie aus Abb. a ersichtlich ist. Hier ist ein Anker a dargestellt, dessen Wicklungsenden w. und w, auf der einen Hälfte zu den Stromwendern ;l und s, führen, während auf den entgegengesetzten Hälften nur die Wickelköpfe k sichtbar sind.The figures represent a four-pole dynamo machine as an exemplary embodiment In Fig. r, m is the magnet frame. A (highlighted by thick lines) Half w of the armature winding is connected to a commutator s. The two Brushes b are attached so that they are at points of greatest voltage difference of the The commutator s take the current generated by one half of the winding. on of the other half of the armature, only the coil heads are ready for their (thinly drawn) Connections visible. They lead to a second commutator, the one on the opposite one Side can be attached, as can be seen from Fig. A. Here is an anchor a shown, whose winding ends w. and w, on one half to the commutators ; l and s, lead, while on the opposite halves only the winding heads k are visible.
