摘要： An energy absorption device (1) for a circuit breaker, in particular a solid-state or a hybrid circuit breaker, includes an energy absorber (20) arranged within an enclosure (10) and a two-phase cooling arrangement. The two-phase cooling arrangement has one or more fluid distribution units (110) configured to direct a cooling fluid in a liquid state toward the energy absorber (20), the energy absorber (20) being cooled due to evaporation of the cooling fluid.
A circuit breaker, in particular solid-state or hybrid circuit breaker, includes one or more energy absorption devices (2, 3, 4).
A method for two-phase cooling of an energy absorber (20) of a circuit breaker, in particular a solid-state or hybrid circuit breaker, includes: after a switching operation of the circuit breaker, directing a cooling fluid in a liquid state toward the energy absorber (20). Thereby, the energy absorber (20) is cooled due to evaporation of the cooling fluid.-

摘要： The disclosure relates to a high-voltage insulator (100) for insulation of a DC conductor of a gas-insulated electrical system, and to a gas-insulated electrical system comprising a high-voltage insulator.
The high-voltage insulator (100) comprises an insulator body (50) and an insulator surface (51), wherein the electrical conductivity of the insulator surface (51) is higher than the electrical conductivity of the insulator body (50); and a contacting element (30). The contacting element (30) comprises an insulator side face (31) having a first height (hres) for connecting a predetermined length of the insulator surface (51) to a definite potential, the contacting element (30) further extending by a total width (w) in a width direction away from the insulator surface (51) up to an end face (32). A second height (hend) of the contacting element (30) at the end face (32) is lower than the first height (hres).-

摘要： A transformer (1) is provided, which comprises a tank (10) having an enclosed volume (11) with an insulating material (13), the tank (10) comprising at least one channel (25) extending through the tank (10), wherein the interior of the at least one channel (25) is separated from the enclosed volume (11) of the tank (10) by a channel wall (17). A transformer core (30) is provided outside of the enclosed volume (11), comprising at least one core leg (32) extending through the tank (10) via the at least one channel (25). At least one coil (50, 52) is located inside the enclosed volume (11), the coil (50, 52) being wound about the at least one channel (25), wherein the tank (10) has an inner wall or outer wall (16) comprising a semiconductive layer (40), which comprises fibers (42) embedded in an impregnating material (44).
