Title:
EXCITATION PROTECTION APPARATUS FOR DOUBLE-PATH OR MULTI-PATH CIRCUIT BREAKING
Document Type and Number:
WIPO Patent Application WO/2024/060597
Kind Code:
A1
Abstract:
The present application relates to the field of electric power and new energy vehicles. Specifically, provided is an excitation protection apparatus for double-path or multi-path circuit breaking. The apparatus comprises an excitation source, a piston structure, and at least two conductors, which are arranged spaced from each other, wherein at least one ends of the conductors are not connected to each other. An impact end of the piston structure is provided with cut ends corresponding to the conductors, and the conductors and the cut ends of the piston structure are respectively arranged side by side or in a staggered manner. When the excitation source receives a trigger signal to act, the piston structure can cut off the conductors at the same time or according to a time sequence. By means of the present application, rapid cutting protection for a multi-load circuit or a multi-branch circuit is realized, and physical fractures between loads or branches are formed, thereby avoiding mutual interference or damage caused by a reverse current or an interference current continuously occurring between the loads or the branches.
