Embodiment Construction

[0034] figure 1 An embodiment of a converter station 1 according to the invention is shown having a diode rectifier 2 arranged in an encapsulation housing 3 filled with insulating material. insulating material in figure 1 The example shown is insulating oil. Furthermore, the converter station 1 comprises a transformer 4 having a primary winding 5 and a secondary winding 6 which are inductively coupled to one another. The transformer 4 is arranged in an encapsulation case 7 filled with the same insulating oil. A hollow-cylindrical supply line 8 , likewise filled with insulating oil, is used for routing the phase conductors connected on the AC voltage side between the transformer 4 and the converter 2 . The encapsulation housings 3 , 7 are at ground potential.

[0035] The converter station 1 also has two smoothing inductors 9 , which are each connected to the two DC voltage connections of the diode rectifier 2 . Each smoothing inductor 9 is arranged in a separate encapsula...

Abstract

The invention relates to a converter station (1) for transmitting electric power, having a diode rectifier (2), the diode rectifier having a DC voltage connection and an AC voltage connection; and at least one transformer connected to the AC voltage connection (4) In order to make the converter station as compact as possible, it is proposed that the diode rectifier (2) is arranged in insulating material.

Description

technical field [0001] The invention relates to a converter station for the transmission of electric power, comprising: a converter having a direct voltage connection and an alternating voltage connection; and at least one transformer connected to the alternating voltage connection, wherein Transformers and converters are arranged in insulating material. Background technique [0002] Such a converter station is known, for example, from "Windpower plant control for the connection to multiterminal HVDC links" by S. Bernal-Perez et al., IEEE, 2012, p. 2873. A device is disclosed there in which a diode rectifier is connected on the DC voltage side to a DC voltage intermediate circuit. The direct voltage intermediate circuit runs between two voltage source converters, also called "voltage source converters (VSC)" in English. The diode rectifier is connected to the wind farm through the transformer and the AC grid. Furthermore, a filter unit arranged on the AC voltage side of t...
