The Study on the Self-Flow Generation Phenomena in a Gas Circuit Breaker

대전류 영역에서의 가스차단기 내의 아크의 자발적인 흐름현상에 따른 에너지 전달의 수치적 해석

This study presents the energy transfer of thermal arc in the circuit breaker with self-generation flow without puffer action. The phenomenon of pressure increase in the cylinder which encloses fixed contact was focused on and rising current stage was considered. Temperature and velocity of arc plasma were calculated by using energy balance equation and the amount of energy transfer due to convective flow was calculated.
