Abstract: Electrical contact system with a first and a second contact (1, 5), each having a contact surface (4, 8). The first electric contact (1) has a mesostructured electric contact portion (14) with a plurality of slots (15) and ridges (16) formed between neighboring slots (16) of the plurality of slots (16). These slots (15) and ridges (16) extend in a direction running transversely to said switching plane (X-Z) form a plurality of current paths (16). The current paths (16) are inclined to the first contact surface (4) at a first angle (17) measuring less than 60 degrees such that an interruption current (12) flowing through the mesostructured electric contact portion (14) and through an electric arc (11) extending in between the first contact surface (4) after lifting the first contact surface (4) off the second contact surface (8) pushes said electric arc (11) in the direction of the apex of said first angle (17) from a first position (18) to a second position (19).

Abstract: The present disclosure relates to power capacitor unit (1) for high-pressure applications. The power capacitor unit (1) comprises a housing (3), a plurality of capacitor elements (5-17, 23-35) connected to each other and arranged inside the housing (3), a dielectric liquid (L), a solid electrical insulation system arranged to electrically insulate each capacitor element (5-17, 23-35), a busbar, a plurality of fuse wires (5a-17a), each fuse wire having a first end connected to a respective capacitor element (5-17, 23-35) and a second end connected to the busbar (B), wherein the capacitor elements (5-17, 23-35), the solid electrical insulation system (41), and the fuse wires (5a-17a) are immersed in the dielectric liquid (L). Each fuse wire (5a-17a) has a plurality of first sections that are in physical contact with the electrical insulation system, and wherein each fuse wire (5a-17a) has a plurality of second sections without physical contact with the solid electrical insulation system.
