[0025] In Example 1, the first mounting seam 7 and the second mounting seam 8 are stretched open using a tool, and the drop-out fuse is placed in the protective cavity 5 from the stretched first mounting seam 7 and the second mounting seam 8. The terminal block of the fuse is placed in the protective cavity 5, which has a good protection effect on various components. The first shell 1, the second shell 2, the first protrusion 3 and the second protrusion 4 are integrally formed to ensure the overall structural strength of the protective cover and meet the safety protection requirements for the drop-out fuse.
[0026] Furthermore, both the first protrusion 3 and the second protrusion 4 are provided with mounting holes 14 for mounting an external temperature sensor.
[0027] In other embodiments, a temperature sensor can be installed on the mounting hole 14 of the fuse protection cover according to actual usage requirements to facilitate real-time monitoring of the temperature of the fuse and its surrounding environment, so that the control system can promptly obtain the working status of the fuse, thereby improving the safety protection capability; and the connecting line between the mounting hole 14 and the temperature sensor maintains a straight interface to avoid false signals caused by bending during temperature changes.
