Problems solved by technology

[0003] A challenge in the construction and design of an HVDC converter station is the electrical isolation of the different parts of the HVDC converter station, since an increase in the distance between the various parts of the HVDC converter station improves the insulation, but at the same time results in a HVDC converter station with less large size
This may cause many difficulties with respect to e.g. installation, transportation and cost, especially for offshore applications

Abstract

The present disclosure relates to a valve arrangement(400) comprising a plurality of valve units (410-450) electrically connected in series. A first valve unit (410) includes a container (130) in which at least one stack of converter cells (120) is arranged. The container is at least partially filled with an electrically insulating gas(115). The valve arrangement further comprises at least one first connector (460) including a first busbar element (461) electrically connecting a cell (421) of the first valve unit at one end of the container to a cell (441) of a second valve unit(420). The first connector is insulated by an electrically insulating gas(465). Further, the valve arrangement comprises at least one second connector (470) including a busbar element (471) for connection of another cell of the first valve unit at another end of the container.

Description

technical field [0001] The present disclosure relates generally to the field of high voltage power converters and focuses on valve arrangements insulated by at least an insulating gas. The valve arrangement of the present disclosure may be adapted for use on offshore platforms, for example. Background technique [0002] A high voltage direct current (HVDC) converter station is a type of station adapted to convert high voltage direct current (DC) to alternating current (AC) or vice versa. An HVDC converter station may comprise components such as the converter itself (or multiple converters connected in series or parallel), AC switchgear, transformers, capacitors, filters, DC switchgear and / or other auxiliary components. Electronic converters can be classified as line commutated converters using, for example, thyristors as switches, or voltage source converters using transistors such as insulated gate bipolar transistors (IGBTs) as switches (or switching devices). A number o...
