Title:
FUSE-SWITCH-DISCONNECTOR ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2023/029614
Kind Code:
A1
Abstract:
The present invention relates to the technical field of low-voltage power distribution systems, and in particular relates to a fuse-switch-disconnector assembly. The fuse-switch-disconnector assembly comprises at least one fuse-switch-disconnector. The fuse-switch-disconnector comprises an isolating switch and a fuse assembly that are detachably connected. The fuse assembly comprises a fuse and a protective box used for accommodating the fuse. The protective box is provided with a heat dissipation channel that dissipates heat from the fuse, and the protective box is further provided with a transparent window by means of which the state of the fuse can be observed. The fuse-switch-disconnector assembly may ensure that the normal operation of other circuits will not be affected when the fuse of a certain circuit is replaced. Moreover, the detachable connection between the isolating switch and the fuse assembly may facilitate the replacement of the fuse assembly, and by means of the transparent window, the fuse may be visualized and the state of the fuse may be promptly observed.
