POWERFUL SUPERCONDUCTIVE SWITCH Russian patent published in 2012 - IPC H01L39/16 

FIELD: electricity.

SUBSTANCE: powerful superconductive switch comprises a control system and a superconductive disconnecting element, which is made of N serial sections and is connected with their outputs to outputs of a superconductive inductive energy accumulator and a DC source and to load outputs. The inductive energy accumulator and the load also comprise N serial sections connected between each other and the disconnecting element section by section in parallel. The control system is connected to the first section of the disconnecting element. Between one of outputs in each section of the disconnecting element and the output of the identical load section there is a winding switched additionally, which is structurally arranged outside the next section of the disconnecting element. The winding connected electrically into the circuit of the N load section is structurally arranged outside the first section of the disconnecting element, creating a closed circuit of windings impact.

EFFECT: lower energy of a control system and higher reliability of a switch by additional use of energy of a magnetic field developed by current flowing in a load circuit.
