SYSTEMS AND METHODS FOR PROVIDING FLUID-AFFECTED FUSES
A fluid-affected fuse includes a structural housing, a pair of electric terminals, one or more fuse elements, and a fluid arranged in an internal volume of the structure. The structure provides rigidity to the fuse. The terminals are coupled to the structural housing and are configured to be coupled to an electric power circuit of a battery circuit. The one or more fuse elements are electrically connected in series to the pair of electric terminals and are arranged in the internal volume. The fluid is configured to affect a temperature of the fuse element. A fluid-filled fuse is filled with fluid, optionally sealed, and operated with the increased heat capacity of the fluid to affect temperature of the fuse. A fluid-cooled fuse is filled with the fluid, undergoing a stream of the fluid thus allowing control of fuse temperature. A control system controls the fluid stream and fuse operation.

Electrical interrupter switching element having passive interruption tripping, in particular for interrupting high currents at high voltages
An example interruption switch includes a casing surrounding a contact unit, defining a current path through the switch, which has two connection contacts, a separation region and a sabot. A current supplied to the contact unit may be interrupted via the one of the connection contacts and discharged via the other connection contact. At least one chamber in the switch, delimited by the separation region, is substantially filled with a vaporizable medium in contact with the separation region. The separation region is separable into at least two parts through the supplied current when a threshold amperage is exceeded. An electric arc forming between the two parts at least partially vaporizes the vaporizable medium, and a gas pressure to which the sabot is exposed forms. The sabot moves, in the casing, from a starting to an end position, achieving an insulation spacing between the connection contacts.
Electrical interruption switching element with a tubular separating element with varying wall thickness
An example electrical interruption switch includes a casing, surrounding a contact unit defining current path therethrough. The contact unit has a first and second connection contact and a separation region. A current supplied to the contact unit via the first connection contact can be discharged therefrom via the second connection contact, or vice versa. The separation region includes a tubular element, an axial direction of which runs along an axis X, wherein the tubular element is separable into two parts along a plane perpendicular to the axis X, whereby the current is interrupted between the first and the second connection contact, wherein the tubular element has two opposite end regions along the direction of extent of the axis X, characterized in that the tubular element has a minimum wall thickness, which increases in each case in the direction of the end regions, in a region between the end regions.
