Claims14
A fuse assembly comprising:
- a fuse element;
- an inner chamber comprising arc-quenching liquid, wherein at least a portion of the fuse element is housed inside the inner chamber, wherein the inner chamber is configured to rupture during an arc event, and wherein each end of the inner chamber is attached to an end disk by adhesive material to seal off the inner chamber in a liquid tight manner and to prevent leakage of the arc-quenching liquid from the inner chamber, and wherein the end disks are configured as a spacer to keep the inner chamber centered inside an outer chamber, each end disk having a diameter greater than a diameter of the inner chamber;
- and
- the outer chamber housing the inner chamber, wherein the outer chamber comprises filler material, wherein the outer chamber further comprises liquid absorbing sheet material that is lined on an inner surface of the outer chamber.

A method of manufacturing a fuse assembly, the method comprising:
- positioning an inner chamber inside an outer chamber, wherein the inner chamber comprises arc-quenching liquid and houses at least a portion of a fuse element, wherein the inner chamber is configured to rupture during an arc event, and wherein each end of the inner chamber is attached to an end disk by adhesive material to seal off the inner chamber in a liquid tight manner and to prevent leakage of the arc-quenching liquid from the inner chamber, and wherein the end disks are configured as a spacer to keep the inner chamber centered inside the outer chamber, each end disk having a diameter greater than a diameter of the inner chamber;
- coupling the inner chamber to a first end cover of the outer chamber;
- filling a space between the inner chamber and the outer chamber with filler material;
- coupling the inner chamber to a second end cover of the outer chamber;
- and
- fixing the second end cover to the outer chamber such that the outer chamber encloses the inner chamber and the filler material, wherein the outer chamber comprises liquid absorbing sheet material that is lined on an inner surface of the outer chamber.
