Abstract

The utility model provides a magneto-electric high-speed diverter switch without power consumption, comprising two groups of static contact iron cores and windings. The two groups of static contact windings are connected in serial or parallel. The utility model is characterized in that a permanent-magnetic movable contact is positioned between the two groups of static contact iron cores and windings, and a contact corresponding to the two groups of static contacts is positioned on the permanent-magnetic movable contact, therefore, a (bi-directional) diverter switch is formed. Another proposal is to change one group of static contact iron cores into iron cores without contacts, and form a (unidirectional) diverter switch. The switch uses the organic combination of electromagnetic induction and magneto-mechanical principles to realize the instant rapid connection or disconnection with a sensitive reaction and fast response. The normal-closed or normal-open condition is maintained without current, so without the ablation of current, the contact has a long service life and high reliability. The utility model is especially suitable to be used as heavy current magneto-electric diverter switch required by the electromotive-power generating multiplex controlling system in the hybrid electromotive vehicle field.
