It is important to understand the aerodynamic characteristics of a circuit breaker nozzle with a complicated inner shape. Therefore, the experimental apparatus was fabricated with air instead of SF_6 as the working fluid. Experiments were conducted using an acrylic nozzle model and a glass nozzle. The flow visualization of flow in the acrylic nozzle model was conducted using the laser light sheet technique, and the flow visualization of flow in the glass nozzle model was conducted using the laser shadowgraph method. Moreover, the flow velocity in the glass nozzle model was measured using a laser velocimeter. Judging from the experimental results, the weak shock is formed in front of the electrode in the circuit breaker nozzle.
