More Information
Summary:The invention discloses a novel drop-out fuse based on a memory alloy temperature deformation spring, and belongs to the technical field of drop-out fuses, the novel drop-out fuse comprises a temperature deformation spring protection structure and a fuse wire protection structure which are connected in series, and the temperature deformation spring protection structure comprises a deformation spring which shrinks along with temperature rise. The two ends of the deformation spring are fixedly connected with the rainproof cover with the conductive performance and the elastic contact piece respectively, and the rainproof cover with the fixed position is connected with an external circuit. The fuse wire protection structure comprises a fuse wire, a rigid fusion tube is arranged outside the fuse wire, the fusion tube is rotatably arranged on an external circuit, the fusion tube is provided with an open end and a closed end, the closed end is made of a conductive material, the fuse wire is in contact connection wit
