DEVICE OF CONTROLLED COMMUTATION Russian patent published in 2012 - IPC H01H83/00 H01H33/04 H02J13/00 H02J7/06 

FIELD: electricity.

SUBSTANCE: device of controlled contains switch, control system (CS), drive-pulse generator (DPG) and fast-acting commutator (FAC). FAC is manufactured in the form of two controlled vacuum arresters (CVA), each of them contains the first main electrode, the second main electrode and control electrode connected to the second main electrode by dielectric insertion. The first CVA is connected to switch in parallel. The second CVA is connected to control electrode of the first CVA by its first main electrode and by its second main electrode it is connected to the first main electrode of the first CVA and the first output of DPG. The second DPG output is connected to control electrode of the second CVA.

EFFECT: increase in reliability of device switching on and decrease of its weight and dimensions.
