| Summary: | 碩士 === 嘉南藥理大學 === 職業安全衛生系 === 107 === The number of domestic fires causes that caused by electrical accidents are remaining obstinately high in Taiwan. Excepting electrical short-circuit, overload, sparks, bad connection and frayed cord, some are caused by Arc-fault. Arc-Fault Circuit Interrupter (AFCI) have been commonly used abroad to protect power outlets from fire. Because Arc-Fault Circuit Interrupter (AFCI) has the function of detecting arcing and automatic power off. In this study, the conductivity produced by various contamination were simulated, and recording the effects produced by the Arc-Fault Circuit Interrupter (AFCI) . From observing the temperature curve produced by the temperature recorder, we found that the conductivity produced by the hydrochloric acid was the highest and the socket or outlet generates sparks due to the continuous high temperature. If the AFCI is installed on the circuit, it can prevent the fire due totracking. In the future, this study might be a reference for house and factories.
