Description

Schaltverfahren zur allmählichen Umwandlung eines von einem Gleichstromwerk gespeisten Dreileiternetzes in ein solches doppelter Spannung. Das Hauptpatent betrifft ein Schaltverfahren zur allmählichen. Umwandlung eines; Gleichstromdreileiternetzes von geringer Spannung in ein solches von höherer Spannung und besteht dann, daß unter möglichst weitgehender Benutzung der vorhandenen Betdebsmittel symmetrisch zum Nulleiter an, die Außenklemmen des ursprünglichen Drei leäternetzes in Hintereinanderschaltung nüt den vorhandenen Sammlerbatterien je eine weitere Batterie von gleicher Spannung wie die der zwischen dem Nulleiter und einer Außenklemme des Netzes liegenden als Ausgleichbatterie angeschaltet wird, ferner zwischen die so. neu :gebildeten Außenklemmen für das Netz höherer Spannung von den vorhandenen Dynamos paarweise zwei in Hintereinanderschaltung zwischen die neu gebildeten Außenklemmen gelegt werden und alsdann das Netz abschnittweise auf die neu gebildeten Außenklemmen umgelegt wird.Switching method for the gradual conversion of one from a direct current plant powered three-wire network in such a double voltage. The main patent concerns a switching method for gradual. Converting a; Direct current three-wire network from low tension to one of higher tension, and then there is that symmetrically using the existing bed resources as much as possible to the neutral conductor, the outer terminals of the original three-wire network connected in series A further battery of the same voltage is used for each of the existing collector batteries like those lying between the neutral conductor and an external terminal of the network as Balance battery is turned on, furthermore between the so. new: formed external clamps for the network of higher voltage from the existing dynamos two pairs in series connection be placed between the newly formed external clamps and then the network in sections is transferred to the newly formed external terminals.

Erfindungsgemäß wird die bei diesem Verfahren verwendete, an die Klemmen der höheren Netzspannung angeschlossene Ausgleichbatterie durch eine Gruppe von Ausgleichmaschinen ersetzt.According to the invention, the one used in this method is applied to the clamps the equalization battery connected to the higher mains voltage by a group of Compensating machines replaced.

Diese Gruppe übernimmt in bekannter Weise den Belastungs- bzw. Spannungsausgleich der beiden Hälften des Netzes höherer Spannung. Durch die Erfindung wird der Vorteil erreicht, daß die Sammlerbatterie ganz entbehrlich wird und damit eine Verbilligung durch Fortfall der hohen Unterhaltungskosten für die Batterie erzielt ist. Die Ausgleiehgruppe - kann, %venn angängig, aus den vdrhandenen- Maschinen des alten Netzes zusammengestellt werden.This group takes on the load or tension equalization in a known manner of the two halves of the higher voltage network. The invention provides the advantage achieved that the collector battery is completely dispensable and thus cheaper by Elimination of the high maintenance costs for the battery is achieved. The Ausgleiehgruppe - Can,% venn accessible, be put together from the existing machines of the old network will.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel des Erfindungsgegenstandes. Die Speiseanlage für das ursprüngliche Netz geringer Spannung ist durch.die Dynamo i, die Schienen B und D, den Nullester C und die Batterie s1 und s2 dargestellt.The drawing illustrates an embodiment of the subject matter of the invention. The feed system for the original low voltage network is through. The dynamo i, rails B and D, zero ester C and battery s1 and s2 are shown.

Zwischen die für das Netz höherer Spannung gebildeten Außenklemmen an den Schienen A und E ist statt einer Ausgleichbatterie die Ausgleichgruppe aus den Maschinen aal und a2 geschaltet.Between the external terminals formed for the higher voltage network on rails A and E, instead of a compensation battery, the compensation group is off the machines aal and a2 switched.

Ferner liegen zwischen den Schienen n, und E die hintereinandergeschalteten Dynamos 2 und 3. Zwischen den Ausgleichmaschinen ,a1 atnd a2 und zwischen den Dynam09 2 und 3 ist in bekannter Weise der Nulleiter angeschlossen. Die allmähliche Umschaltung der einzelnen Netzteile auf die höhere Spannung erfolgt wie im Hauptpatent.Furthermore, the dynamos 2 and 3 connected in series are located between the rails n and E. Between the equalizing machines, a1 and a2 and between the dynamos 2 and 3, the neutral conductor is connected in a known manner. The gradual switchover of the individual power supply units to the higher voltage takes place as in the main patent.
