Description

technical field [0001] The invention relates to metal materials, in particular to a high-conductivity silver-based melt material used as a fuse for short-circuit and over-current protection in electrical equipment, and also relates to a melting method for the high-conductivity silver-base melt material. Background technique [0002] In high and low voltage power distribution systems, control systems and electrical equipment, fuses are used as short-circuit and over-current protectors, and are one of the most commonly used protection devices. Generally speaking, the fuse is mainly composed of three parts: the fuse, the shell and the support, among which the fuse is the key component to control the fusing characteristics. [0003] The material, size and shape of the melt determine the fusing characteristics of the fuse. The melt materials are mainly divided into two categories: low melting point and high melting point. Materials with low melting point, such as lead and lead ...
