摘要： A rupture reduction system for fluid-immersed electrical equipment includes a turret for mounting of a bushing. The turret is expandable in volume in response to a surge in pressure of the fluid in the turret. The expansion volume can be provided by an expandable section of the turret, which may include a bellows.

摘要： In at least one embodiment, the housing part is configured to be connected to an electric component, to house an electric line, and to be filled with a liquid. The housing part comprises an electrically conductive material and has an open mounting side to be connected to the electric component. A surface-to-volume ratio of the housing part is at least 3 m-1, and a ratio of the volume and a wall rupture pressure of the housing part is at least 0.02 m3MPa-1. A corresponding electric system is operated so that, when an electric arc occurs in the housing part, the housing part absorbs a pressure rise that is led into a component tank.

摘要： An electric arrangement comprising a casing; a heat generating electric component arranged inside the casing; and a heat exchanger comprising a three dimensional lattice cell structure, the three dimensional lattice cell structure being arranged to conduct a dielectric cooling fluid from the casing at an exterior side of the casing for heat exchange with an ambient fluid, and back towards the casing for cooling of the electric component. A panel for a heat exchanger and a heat exchanger comprising a plurality of panels are also provided.
