| 摘要 |
The invention relates to a first arrangement (1) comprising a converter (3), which has at least one phase module (15, 24, 31), an AC voltage connection (5), a first DC voltage connection (16), and a second DC voltage connection (17). A first phase module branch (11) is formed between the AC voltage connection (5) and the first CD voltage connection (16); a second phase module branch (13) is formed between the AC voltage connection (5) and the second DC voltage connection (17). Each phase module branch has at least two submodules (1_1, 1_2, 1_3, 2_1, 2_2, 2_3). The submodules (1_1, 1_2, 1_3) of the first phase module branch (11) are surrounded by a first housing (35) which is suitable for receiving a gaseous substance (88), and the submodules (2_1, 2_2, 2_3) of the second phase module branch (13) are surrounded by a second housing (37) which is suitable for receiving the gaseous substance (88). |
