Title:
FUSE CABINET
Document Type and Number:
WIPO Patent Application WO/2020/103483
Kind Code:
A1
Abstract:
A fuse cabinet. The fuse cabinet comprises a cabinet body (101) and a fuse (102) provided in the cabinet body (101). A striker of the fuse (102) used for driving a trip mechanism (104) to act is provided on the fuse (102). The striker of the fuse (102) drives the trip mechanism (104) to perform a trip action by means of a booster mechanism (103). The booster mechanism (103) comprises a trip driving member (3), and the trip driving member (3) has an energy storage stroke and a release stroke. The booster mechanism (103) further comprises an energy storage elastic member (8) connected to the trip driving member (3) so as to apply an elastic force to the trip driving member (3) to force the trip driving member to act towards the release stroke. An energy storage completion position is provided on the energy storage stroke of the trip driving member (3). The booster mechanism (103) further comprises a locking and unlocking structure used for blocking the trip driving member (3) at the energy storage completion position and unlocking the trip driving member (3) when the fuse (102) is blown. The described solution effectively increases the driving force of the trip driving member (3) by means of adding the booster mechanism (103), which thereby ensures the opening and tripping effect of the fuse cabinet, and improves the safety of equipment operation.
