EXPLOSIVE DISCONNECTOR Russian patent published in 2021 - IPC H01H39/00 

FIELD: explosives.

SUBSTANCE: invention relates to explosive disconnector. The disconnector has two current leads, a metal cylinder connected to one current lead, and a metal membrane having an electrical connection to another current lead and a metal cylinder. One explosive charge is placed in a metal cylinder covered from the outside by rings and cooled from the inside by a liquid dielectric, and another explosive charge is placed on the side of the cover of the dielectric cylinder installed with the possibility of moving to the membrane and cutting it. When the charges are simultaneously detonated, the metal cylinder is first torn on the rings, and then the membrane is cut.

EFFECT: increased electrical strength of the breaker, its increased current-carrying capacity and the voltage maintained in the open state
