Summary :

To evaluate heat and fire phenomena caused by accumulated microslide motion on an imperfectly connected electrical terminal, an acceleration test method using vibrator was developed. The process from the generation of CuO to that of Cu₂O has been reproduced. The influence of current is investigated, and it is found that as current increases, CuO generation time T1 and Cu₂O generation time T2 decrease for pure copper, however when current exceeds 3 A, we could not produce CuO or Cu₂O. The contact resistances of a Cu terminal and wire, compared with the terminal material were investigated in terms of the effects of current and ambient temperature.
