Description

Einrichtung zur gleichzeitigen Übertragung von einphasigem Wechselstrom durch parallel arbeitende Teile eines mehrphasenstrom übertragenden Leitungssystems In der Patentschrift 45¢ 636 ist eine Einrichtung zur gleichzeitigen Übertragung von Einphasenwechselstrom auf Mehrphasenstromleitungssystemen beschrieben, bei der die parallel arbeitenden Leiter des Mehrphasensystemsauf magnetischem oder elektrischem Wege mit Hilfe besonderer Transformatoren verkettet sind.Device for the simultaneous transmission of single-phase alternating current by parts of a multi-phase power transmission line system that work in parallel In patent specification 45 [636] there is a device for simultaneous transmission of single-phase alternating current on multi-phase power line systems, in which the conductors working in parallel of the multiphase system on magnetic or electrical Paths are chained with the help of special transformers.

Erfindungsgemäß kann nun die Verkettung der parallel arbeitenden Leiter des Mehrphasensystems auch auf folgende Weise vorgenommen werden.According to the invention, the concatenation of the conductors working in parallel can now of the multi-phase system can also be made in the following manner.

Die beiden - willkürlich ausgewählten -parallelen Leiter ii und u' des als Drehstromdoppelleitung ausgebildeten Mehrphasensystems werden in einem Punkt p vereinigt, der mit der Mitte einer Einphasenwicklung metallisch verbunden ist. An die freien Spulenenden der Einphasenwicklung x und x' werden die gleichen parallelen Leiter u und u' des Mehrphasensystemsgabelförmig wieder angeschlossen und in gewöhnlicher Weise. auf dem Leitungsgestänge oder in einem Kabel weitergeführt bis zur Endstelle des Doppelfrequenzbetriebs, die in genau gleicher Weise, nur in umgekehrter Reihenfolge, aufgebaut ist wie die Anfangsstelle. Die Einphasenwicklung kann dabei als reine Drosselspule (Abb. z) ausgebildet werden, deren Spulenenden die Einphasenspannung unmittelbar zugeführt wird; die Einphasenwicklung kann aber auch als Sekundärwicklung eines Transformators (Abb. a) ausgebildet werden, die dann zugleich eine transformatorische Änderung der Einphasenspannung vor und hinter der Übertrittsstelle auf die Mehrphasenleitung ermöglicht.The two - arbitrarily selected - parallel conductors ii and u 'of the multi-phase system designed as a three-phase double line are combined at a point p which is metallically connected to the center of a single-phase winding. The same parallel conductors u and u 'of the multi-phase system are re-connected in a fork-shaped manner to the free coil ends of the single-phase winding x and x' and in the usual manner. Continued on the line rod or in a cable to the end point of the double frequency operation, which is constructed in exactly the same way, only in the reverse order, as the starting point. The single-phase winding can be designed as a pure choke coil (Fig. Z), the coil ends of which are supplied with the single-phase voltage directly; The single-phase winding can also be designed as a secondary winding of a transformer (Fig. a), which then simultaneously enables a transformer change in the single-phase voltage before and after the transition point to the multi-phase line.

Abb.3 zeigt schließlich noch, daß in die Mitte der Einphasenwicklung an Stelle zweier parallel arbeitender Leiter des Mehrphasensystems auch ein einziger Leiter eingeführt werden kann, der sich aber dann mit Hilfe der Einphasenwicklung gabelt und erst auf der Endstelle des Doppelfrequenzbetriebs wieder zu einem einzigen Leiter vereinigt werden kann.Finally, Fig.3 shows that in the middle of the single-phase winding instead of two conductors working in parallel in the multiphase system, there is also a single conductor Conductor can be introduced, but then with the help of the single-phase winding forks and only back to a single one at the end of the double-frequency operation Head can be united.

In allen diesen Fällen ist durch die gleichsinnige Wicklung der beiden Einphasenwicklungshälften erreicht, daß die von dem sich gabelnden Mehrphasenstrom herrührenden Amperewindungen in den beiden Spulenhälften sich aufheben, während die vom Einphasenstrom herrührenden Amperewindungen in beiden Spulenhälften sich unterstützen. Der Mehrphasenstrom erleidet also beim Durchströmen der Einphasenwicklung keinen zusätzlichen induktiven Spannungsverlust, während für den Einphasenstrom die Wicklung ihre normale Gegen-EMK entwickelt.In all of these cases is due to the co-winding of the two Single-phase winding halves achieved that of the bifurcating multiphase current The resulting ampere turns in the two coil halves cancel each other out while the ampere-turns resulting from the single-phase current in both coil halves support. The multiphase current suffers when flowing through it the single-phase winding does not have any additional inductive voltage loss, while for the single-phase current the winding develops its normal back EMF.

Auch können bei Verwendung dieser Anordnung einzelne willkürlich wählbare Traversen mit j e zwei parallelen Leitern des Mehrphasensystems zur Überlagerung der Einphasenspannung benutzt werden, ohne daß im normalen Betrieb die übrigen Traversen des Leitungszuges eine Potentialerhöhung erfahren oder einphasige Ausgleichsströme führen. Es wird also erheblich an Isolationsaufwand gespart, da erhöhte Isolation nur für die jeweils simultan geschaltete einzelne Traverse nötig wird.Individuals can also be selected at will when using this arrangement Trusses with two parallel conductors of the multi-phase system for superimposition the single-phase voltage can be used without the other traverses during normal operation of the cable run experience a potential increase or single-phase equalizing currents to lead. This saves a considerable amount of effort in terms of insulation, since there is increased insulation is only required for the individual traverse that is switched simultaneously.

Schließlich kann bei Verwendung dieser Anordnung eine willkürlich wählbare Teillänge des ganzen Leitungszuges für Doppelfrequenzbetrieb eingerichtet werden, ohne daß die vor der Aufnahme- bzw. hinter der Entnahmestelle des Einphasenstroms liegenden Leitungs- und Anlagenteile des Mehrphasensystems im normalen Betrieb zusätzliche Einphasenspannungen oder Einphasenausgleichsströme führen. Es wird also nicht nur der Isolationsaufwand für die Leitung kleiner, sondern es entfällt auch die Notwendigkeit, die vor der Aufnahme- bzw. hinter der Entnahmestelle des Einphasenstroms liegenden Umspannwerke und Schaltanlagen für höhere Spannung auszurüsten, als die normale Betriebsspannung des Mehrphasengrundsystems ohnedies erforderlich .macht.Finally, using this arrangement, one can be arbitrary selectable partial length of the entire cable run set up for double frequency operation without the in front of the intake or after the extraction point of the single-phase stream additional line and system parts of the multi-phase system in normal operation Lead single-phase voltages or single-phase equalizing currents. So it just won't the insulation effort for the line is smaller, but there is also no need to those located in front of the intake or after the extraction point of the single-phase stream Equip substations and switchgears for higher voltages than normal The operating voltage of the multiphase basic system is required anyway.
