Title: TRANSFORMER FOR HIGH-VOLTAGE DIRECT-CURRENT TRANSMISSION
Abstract:
The aim of the invention is to provide a compact and cost-effective arrangement (1) for connecting a converter (15) to a high-voltage network carrying an alternating current, said arrangement comprising a number of single-phase transformers (2, 3, 4) that each comprise a valve winding (7) for connecting the converter (15) and a network winding (8) for connecting to the high-voltage network, where a valve end (10) of the valve winding (7) is connected to an outside connection (12) of a valve passage (11) and an interconnection end (20) of the valve winding (7) is connected to the interconnection end (20) or the valve end (10) of the valve winding (7) of another single-phase transformer (2, 3, 4) of the arrangement (1). To this end, each interconnection end (20) is connected to the interconnection end (20) or the valve end (10) of a single-phase transformer by means of a connection unit (21), and each connection unit (21) comprises a connection housing (22) filled with an insulating fluid, in which an electroconductive jumper (23) extends.
