Document Type and Number:
WIPO Patent Application WO/2022/121231
Kind Code:
A1
Abstract:
A multi-breaking exciting fuse having a rotating structure comprises two shells, a conductor horiozontally arranged in one of the shells, a gas generating device and a piston arranged above the conductor from top to bottom; arc-shaped grooves, which are respectively formed within one of the shells on both ends thereof along a length direction of the conductor; breaking areas respectively provided at a middle part of the conductor located in the housing and on the conductor at the two sides where the arc-shaped grooves are formed; a rotating support block, which can be displaced along the arc-shaped grooves, is fixedly arranged below the conductor between the breaking areas; and an impact end of the piston located at the breaking area in the middle of the conductor. The exciting fuse of the present disclosure improves the breaking capability and the arc extinguishing capability.
