Abstract: PURPOSE: An arc-extinguishing unit of a gas insulated circuit breaker is provided to prevent dielectric breakdown by partially discharging heated gas when a certain pressure is formed in a cooling room. CONSTITUTION: A fixed electrode part(100) includes a fixed electrode rod(120). A moving electrode part(200) faces the fixed electrode part. The moving electrode part includes a moving electrode rod(220). A pressure outlet includes a pressure discharging hole and a switching valve opening and closing the pressure discharging hole. The pressure discharging hole is included at least one of a fixed side supporting body(110) or a moving side supporting body(210).
