The influence of working environment temperature on fuse life:
Excessive ambient temperature will damage the life of the fuse. For time-delay (slow-blow) fuses such as tin ball type, tin begins to diffuse into the metal wire when the temperature is about 160℃ (150~170℃). The temperature at which the fusible element (metal wire) of the fast-blow fuse begins to oxidize more violently is about 200℃ (175~225℃). With the oxidation of the fuse from the outside to the inside, multiple diffusions, thermal stress fatigue, etc., the life of the fuse will gradually shorten. Therefore, it is recommended that the time-delay fuse should not work for a long time above 150℃, and the fast-blow fuse should not work for a long time above 175~225℃.
The influence of pulse current on the life of the fuse:
Continuous pulse impact will produce thermal cycles, which will cause diffusion, oxidation, thermal stress, etc.. of the fuse, and even accelerate it. The fuse will gradually age with the increase of pulse energy and number of times. The impact resistance life of the fuse depends on the percentage of the pulse I2t to the fuse’s own I2t. Normally, it should be less than 20[%], so that the fuse can withstand more than 100,000 impacts.
Such as the pipe clamp in contact with the fuse, and the length and cross-sectional area of the connecting wire. The contact resistance between the fuse and the pipe clamp is large, which is detrimental to the life. The UL standard stipulates that the contact resistance between the fuse and the pipe clamp is less than 3mΩ during the test. When the contact resistance is large, the pipe clamp does not dissipate heat but generates heat and transmits it to the fuse.
