SUPERCONDUCTIVE SWITCH Russian patent published in 2013 - IPC H01L39/16 

FIELD: electricity.

SUBSTANCE: superconductive switch is designed for switching current of superconductive inductive accumulators of energy and superconductive magnetic systems, in systems of protection of superconductive windings of electric machines, power transmission lines and superconductive cables. The concept of the invention is as follows: the superconductive switch comprises a superconductive disconnecting winding, outputs of which are connected to outputs of an energy source, a control system comprising serially connected capacitor, main control winding and closing device, to the outputs of the disconnecting winding there is a circuit connected in parallel comprising a load and an auxiliary control winding. The disconnecting winding and the auxiliary control winding are arranged in the form of N serial sections, and the main control winding is arranged on the first section of the disconnecting winding, and each of sections of the auxiliary control winding is installed on the identical section of the disconnecting winding.

EFFECT: reduced energy of a control system due to reduction of a volume of superconductive material in part of a disconnecting winding, which is exposed to the main control magnetic field.
