Project summary

The given project is aimed at making a combination current breaker on the basis of a vacuum interrupter and a plasma opening switch. The development of this breaker will make it possible to use relatively cheap slow-acting storages of energy for generating pulses of nanosecond duration. At present, no combination breakers of similar type exist. Vacuum interrupters and plasma opening switches exist, but each acts in its temporary range.

A team of researchers at TRINITI have gained experience in experimental and theoretical investigations in the field of commutation devices including vacuum interrupters. Specialists from RF NC-VNIITF have made much progress in the area of plasma opening switches. The proposed engineering solution will allow the physical processes proceeding in the vacuum gap at switching and transmitting energy to load to be studied and, thus, the electrical capabilities of the combination current breaker to be estimated.
