    摘要： A high-voltage direct-current thermal fuse includes one or more fusible components each having two fusible alloy support arms, a fluxing agent, a fusing cavity, two pins, and an insulation block. Two fusible alloy support arms are arranged opposite, and the fusible component is U-shaped. The fusible component and the fluxing agent are sealed within the fusing cavity. The two pins are respectively connected to the two fusible alloy support arms. The insulation block is arranged between the two fusible alloy support arms and separates the two pins. A volume ratio of the fluxing agent to the fusing cavity is approximately 50% or less, preferably, 10%-50%. The number of the one or more fusible components is at least two, and the at least two fusible components are arranged separately. The thermal fuse can avoid the burst and quickly cut off the current, which provides effective thermal protection for a circuit.

    摘要： A high-voltage fusing apparatus includes a current fuse, a temperature fuse, and a current-carrying fuse. The current fuse is connected in series with the temperature fuse, and a series branch of the current fuse and the temperature fuse is connected in parallel with the current-carrying fuse. A resistance value of the current-carrying fuse is less than a resistance value of the current fuse, and a fusing temperature of the current-carrying fuse is lower than a fusing temperature of the temperature fuse. The high-voltage fusing apparatus can cut off a high-voltage circuit quickly, and effectively protect the high-voltage heating circuit from overheating.

    摘要： It is an object of the invention to provide an electric wire having an excellent electrical conductivity in use of the high melting point metal and being able to surely cut off by fusing the conductive material itself at a temperature lower than the melting point of the high melting point metal, even where heat is generated from flowing overcurrent in the electrical circuit. The electric wire of the invention has a feature including a conductive material formed of a first conductive member made of a low melting point metal, and a second conductive member made of a high melting point metal, which are provided adjacent to each other, wherein the conductive material is fused by erosion of the high melting point metal according to melting of the low melting point metal.
