HIGH-VOLTAGE DIRECT-CURRENT THERMAL FUSE
First Claim
1. A high-voltage direct-current thermal fuse, comprising:
- a fusible component having fusible alloy support arms, wherein the fusible alloy support arms do not intersect;
a fluxing agent;
a fusing cavity, wherein the fusible component and the fluxing agent are sealed within the fusing cavity; and
pins, wherein the pins are respectively connected to the fusible alloy support arms.

Abstract
A high-voltage direct-current thermal fuse including: a fusible component having two fusible alloy support arms parallel to each other; a fluxing agent; a fusing cavity; and two pins. The fusible component and the fluxing agent are sealed within the fusing cavity. The two pins are respectively connected to the two support arms. Technically, the fluxing agent only needs to have contact with the fusible alloy. Practically, the fluxing agent is usually coated over the fusible alloy. The fusible component in the high-voltage direct-current thermal fuse of the present application is a U-shaped structure having two parallel support arms. A high electric field intensity is generated when an arc is being cut off, as a result, the electrons repel each other, and the arc is lengthened, thereby increasing the speed of cutting off the arc.
