Fire Characteristics of Circuit Breakers for Low Voltage during Switching Arcs according to the Characteristics of Combustibles
초록
In this paper, the fire characteristics of circuit breakers for low voltage during switching arcs were analyzed according to the characteristics of combustible materials. Arc dispersion and ignition process were taken by high speed imaging system and digital camera. In this experiment, four resistors were connected as loads. To discover the fire characteristics of circuit breakers by combustible materials, ethanol and cotton were installed as combustibles near contacts respectively. In case of ethanol, fire broke out near the contacts while switch was turned on and turned off. Whereas, in case of cotton, fire broke out near deteriorated contacts while switch was turned off.
