Title:
MULTI-EXCITATION-SOURCE PROTECTION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/045422
Kind Code:
A1
Abstract:
The present disclosure relates to the fields of electric power control and electric vehicles. Disclosed is a multi-excitation-source protection apparatus, comprising a first conductor, a first fuse and a second conductor, which are sequentially connected in series, and further comprising a first excitation source, a second excitation source and at least one self-excitation trigger circuit, wherein the first excitation source and the second excitation source are integrated together; the self-excitation trigger circuit is connected to the first fuse in parallel, and the self-excitation trigger circuit is respectively electrically connected to the first excitation source and the second excitation source, to send a trigger signal thereto; and the first excitation source and the second excitation source act according to the trigger signal to drive a disconnection apparatus to disconnect the first conductor or the second conductor. In the present disclosure, multiple excitation sources are combined with multiple trigger-signal sending modes, such that the operational reliability of a protection apparatus is improved.
