Abstract

The invention relates to a thermo magnetic release mechanism for a circuit breaker protecting electric circuits in electric transmission networks and in particular for a circuit breaker protecting the electric circuit of an electric energy receiver or receivers against short circuits or overloads. The thermo magnetic release mechanism (4 4 ) for an electric power circuit breaker (2) comprises an electric circuit and a magnetic circuit both connected mechanically and electrically with a drive element (5) of the circuit breaker. The magnetic circuit comprises a permanent magnet (8) and elements of a magnetically soft material connected to its poles which elements are the yokes of the circuit (9a 9b) or (9a 9b ) between which the armature of the magnetic circuit is located. The invention is characterized in that the armature is an electromagnet (10) made of two separable cores one immovable (10a) and one movable (10b) or (10b ) individually connected with the respective pair of yokes (9a 9b) or (9a 9b ) and contacting each other frontally in the closed state of the release mechanism (4 4 ) and it is made of a ferromagnetic material which when heated above the Curie (Tc) temperature changes its ferromagnetic characteristics to paramagnetic characteristics and the coils (11a lib) of the electromagnet (10) are wound on separable elements of the core (10a 10b or 10b ) in directions opposite to one another with respect to both separable elements.
