Abstract :
The basic experimental data obtained with a large current opening switch for current commutation using explosives are presented. The experimental results show that currents up to a maximum of 40 kA can be completely interrupted within 30 μs. The mechanism of current interruption using a thin conductor plate and methods of measuring interrupting current with a pick up coil and taking photographs with a high-speed camera (1 frame/μs) are discussed
