POLARIZED HIGH-SPEED ELECTROMAGNET Russian patent published in 2023 - IPC H01F7/06 H01H71/24 H01F7/16 H01H51/06 

FIELD: electrical engineering.

SUBSTANCE: invention is related to protective switching equipment and can be used to protect against overloads and short circuits of electrical installations and DC lines. A polarized high-speed electromagnet is a magnetic circuit, through the window of which a current-carrying bus, an armature, a spring and a permanent magnet are passed. The permanent magnet is installed in the magnetic circuit of the magnetic circuit parallel to the armature and is magnetized along the magnetic lines of the magnetic circuit. The armature doesn’t touch the permanent magnet in the initial or in the final position.

EFFECT: resistance to shock loads and reduction in size and simplification of the design of a polarized high-speed electromagnet
