    • A high-voltage direct-current thermal fuse comprising a high-voltage low-current thermal fuse connected to a high-voltage direct-current circuit. The high-voltage low-current thermal fuse comprises a casing, fusible alloy wires, wherein the fusible alloy wires are connected between the two leads. One of the leads is sequentially sleeved with an arc extinguishing sleeve and a spring. One end of the arc extinguishing sleeve is in contact with the fusible alloy wires; and the other end of the arc extinguishing sleeve is in contact with the spring. One end of the spring is connected to the inner end face of the casing; and the spring is in a compressed state. The high-voltage direct-current thermal fuse further comprises a conventional thermal fuse; or further comprises a current. The high-voltage direct-current thermal fuse solves the problem of timely arc cutting-off and can be directly applied to a high-voltage direct-current circuit.
    • 一种高压直流热熔丝,包括连接到高压直流电路的高压低电流热熔丝。 高压低电流热保险丝包括外壳,易熔合金线,其中​​可熔合金线连接在两根引线之间。 其中一根导线依次用灭弧套筒和弹簧套管。 灭弧套筒的一端与可熔合金丝接触; 灭弧套筒的另一端与弹簧接触。 弹簧的一端连接到壳体的内端面; 弹簧处于压缩状态。 高压直流热熔丝进一步包括常规热熔丝; 或进一步包括电流。 高压直流热保险丝解决了及时灭弧的问题,可直接应用于高压直流电路。
