Large-current fuse with multi-fusion-tube structure

A high-current fuse with a multi-fusion-tube structure is formed by combining a plurality of fusion tubes which are independent and parallel, gaps are reserved among the fusion tubes, a plurality of fuses which are installed according to rated current requirements are respectively and oppositely and uniformly distributed in the fusion tubes, and the fusion tubes are jointly installed on a contact to form a whole. According to the utility model, material cost can be saved, production processes can be reduced, manufacturing difficulty can be reduced, temperature rise and power consumption can be reduced under the condition that installation space does not need to be enlarged and additional heat dissipation facilities or cooling equipment does not need to be added in the operation process of the fuse, stable operation on a line can be ensured, reliable safety protection can be provided for electric equipment, and the service life of the fuse is prolonged. The method can be widely applied to protection of electri
