Description
Stroraversorgungsanlage für Schwimmdocks
Ist für das Schiffsbordnetz Gleichstrom nötig, dann wird der Strom dem Anschlußkasten 8 entnommen, der entweder über den Gleichrichter 9 vom Landnetz bzw. vom Wechselstromgenerator 2 oder unmittelbar vom Gleichstromgenerator 3 gespeist wird.If direct current is required for the ship's on-board network, the current is taken from the connection box 8 , which is fed either via the rectifier 9 from the shore network or from the alternating current generator 2 or directly from the direct current generator 3 .
Bei Notstromversorgung treibt der Dieselmotor 1 den Wechselstromgenerator 2 mit Nenndrehzahl. Der so gewonnene Strom von 380 V, 50 Hz speist den Anschlußkasten 6 (Dockbordnetz). Der Gleichstromgenerator 3 kann gegebenenfalls mitangetrieben werden und auf den Dockanschlußkasten 8 arbeiten.In the case of an emergency power supply, the diesel engine 1 drives the alternator 2 at the rated speed. The electricity of 380 V, 50 Hz obtained in this way feeds the connection box 6 (on-board docking system). The direct current generator 3 can, if necessary, also be driven and work on the dock connection box 8 .
Bei einer möglichen Stromversorgung aus dem Landnetz rnit Drehstrom von 380 V, 50 Hz und Gleichstrom von 220 V lassen sich, unter der Annahme, daß das Dockbordnetz stets mit Drehstrom von 380 V, 50 Hz, und zwar über den Anschlußkasten 6, gespeist wird, beispielsweise die beiden folgenden Bedingungen mit zwei verschiedenen Betriebsformen verwirklichen-1. Das Schiffsbordnetz erfordert Drehstrom von 440 V, 60 Hz: a) Der Dieselmotor 1 treibt den Wechselstromgenerator 2 mit erhöhter Drehzahl.With a possible power supply from the shore network with three-phase current of 380 V, 50 Hz and direct current of 220 V, assuming that the dock's on-board network is always fed with three-phase current of 380 V, 50 Hz via the connection box 6 , For example, realize the following two conditions with two different operating modes- 1. The ship's electrical system requires three-phase current of 440 V, 60 Hz: a) The diesel engine 1 drives the alternator 2 at increased speed.
b) Der vom Landnetz gespeiste Gleichstrommotor 3 treibt den Wechselstrommotor 2 mit erhöhter Drehzahl. Der Dieselmotor 1 ist abgeschaltet. b) The direct current motor 3 fed by the land network drives the alternating current motor 2 at an increased speed. The diesel engine 1 is switched off.
In beiden Fällen speist der Wechselstromgenerator 2 den Anschlußkasten 7. In both cases, the alternator 2 feeds the junction box 7.
2. Das Schiffsbordnetz erfordert Gleichstrom 110 V: a) Der Dieselmotor 1 treibt den Gleichstromgenerator 3. 2. The ship's electrical system requires 110 V direct current: a) The diesel engine 1 drives the direct current generator 3.
b) Der vom Landnetz gespeiste Wechselstrommotor 2 treibt den Gleichstromgenerator 3. In beiden Fällen speist der Gleichstromgenerator 3 den Anschlußkasten 8. Treibt der Dieselmotor 1 beide elektrischen Maschinen 2 und 3, dann stehen gleichzeitig zwei verschiedene Wechselspannungen verschiedener Frequenz und zwei verschiedene Gleichstromspannungen nach Wahl für die Stromversorgung zur Verfügung. Die Erfindung ist nicht auf Anlagen nach dem Ausführungsbeispiel beschränkt. So können beispielsweise Zahl, Art und Anordnung der Maschinen im Rahmen der Erfindung beliebig verändert und auch Getriebe zur Drehzahländerung verwendet werden. b) The AC motor 2, which is fed by the shore network, drives the DC generator 3. In both cases, the DC generator 3 feeds the junction box 8. If the diesel engine 1 drives both electrical machines 2 and 3, then two different AC voltages of different frequencies and two different DC voltages of your choice are available at the same time the power supply is available. The invention is not restricted to systems according to the exemplary embodiment. For example, the number, type and arrangement of the machines can be changed as required within the scope of the invention and gears can also be used to change the speed.
Der besondere Vorteil der Stromversorgungsanlage gemäß der Erfindung ist ihre große Anpassungsfähigkeit an die sich stets wandelnden Bedürfnisse hinsichtlich des Leistungsbedarfes des Dock- oder des Schiffsbordnetzes sowie der unterschiedlichen Stromart, Spannungshöhe und Frequenz des Schiffsbordnetzes unter Berücksichtigung der unerläßlichen Forderung nach einer ausreichenden Notstromversorgungseinrichtung, die möglichst wirtschaftlich ausgenutzt werden kann.The particular advantage of the power supply system according to the invention is their great adaptability to the ever changing needs regarding the power requirements of the dock or ship's on-board network as well as the different Type of current, voltage level and frequency of the ship's on-board network taking into account the indispensable requirement for a sufficient emergency power supply facility, which can be exploited as economically as possible.
