MAGNETIC TEMPERATURE RELAY

摘要

The invention relates to a magnetic temperature relay applicable to industrial electric and electronic drives, automation, etc. The relay comprises a moving magnetic armature (3), a stationary ferromagnetic core (1) provided with a control winding (2) thereon. The ferromagnetic core (1) acts on the moving armature (3) with a force proportional to the magnetic permeability value of the material it is made of. When the temperature of the magnetic core (1) approaches the Curie temperature of the material it is made of, the attractive force F 1 drops abruptly and releases the armature (3).
