    摘要: A power capacitor unit for high-pressure applications is provided. The power capacitor unit includes a housing, a plurality of capacitor elements connected to each other and arranged inside the housing, a dielectric liquid (L), a solid electrical insulation system arranged to electrically insulate each capacitor element, a busbar, a plurality of fuse wires, each fuse wire having a first end connected to a respective capacitor element and a second end connected to the busbar (B), wherein the capacitor elements, the solid electrical insulation system, and the fuse wires are immersed in the dielectric liquid (L). Each fuse wire has a plurality of first sections that are in physical contact with the electrical insulation system, and wherein each fuse wire has a plurality of second sections without physical contact with the solid electrical insulation system.
