Sliding contact device e.g. for all types of movable mechanical contacts including slip-rings for electric motors

摘要

The contact device (4) has at least two relatively displaced mechanical contacts, with a filter (3,5) coupled to at least one of the contacts for transforming the parasitic inductance resulting from the contacts and the associated cabling into an impedance with a lesser imaginary component. A filter can be associated with each contact of the contact device, e.g. with the transformation effected via parallel capacitor circuits on either side of the contact device.
