[0003] When the fuse of the existing fuse blows, the container tube with the blown fuse needs to be removed. The staff needs to prepare two specifications of container tubes, take a new container tube with the same specifications as the replaced container tube from the two container tubes, and then install the fuse in the new container tube. In the process of installing the fuse, it is necessary to loosen the nuts at both ends of the container tube, wrap one end of the fuse around the bolt at the lower end of the container tube, and then tighten the nut to press the fuse onto the screw at the lower end of the container tube, adjust the tightness of the fuse, and then wrap the other end of the fuse around the bolt at the upper end of the container tube, and then tighten the nut to press the fuse onto the screw at the upper end of the container tube, and then install the container tube with the replaced fuse on the drop-out fuse;
