Magnetic field distribution in combined opening switch (first stage acting)

Summary form only given. For inductive storage (IS) adaptation to pulsed power generation it is necessary new on principle approach to generator construction, especially under power generation equal 10/sup 12/W and higher. Used in IS circuit switching device, namely opening switch, is one of restricting factors. One of possible solutions of this problem, which is developed with regard to that IS peculiarities of principle IS and opening switches, is offered. On first stage of working of combined opening switch (COS) a magnetic field distribution has great importance, more exactly, on the stage of energy storing. Ampere force acting on electrodes of vacuum breaking may be significant, what may cause electrodes breaking. Under electrodes moving apart a magnetic field will push out an arc from burning area and results in disorder of COS working. The considered geometry of leading bars allows to reduce a value of component of magnetic field in area of movable electrode axis and burning arc down to zero. An estimate of optimal correlation between size of electrodes and their amount in axis symmetrical construction of COS is done.
