ELECTROMAGNET ACTUATING CONTROL ELEMENT, IN PARTICULAR, FOR MEDIUM VOLTAGE BREAKER Russian patent published in 2011 - IPC H01F7/16 

FIELD: electricity.

SUBSTANCE: invention relates to the field of electric engineering, namely, to electromagnet actuator control element, in particular, for medium voltage breaker. Device comprises magnetic circuit, including movable magnetic rectangular core with control coil and movable circular yoke complying with magnetic circuit. Technical result is achieved by the fact that yoke (3) is fixed on driving axis (4), which on one side movably passes through centre of magnetic core, and on the other side is connected to switched traction rod of contact closure, side of driving axis passing through magnetic conductor, protrudes outside with lower end and is connected to the second yoke (7), smaller in side size.

EFFECT: improved compactness and increased capacity.
