FIELD: transport engineering.
SUBSTANCE: invention relates to power supply lines in contact with vehicle current collectors and it can be used for suppressing self-sustained oscillations of contact system. proposed device includes contact wire and self-sustained oscillation suppressors. Flexible working cable with insulator is secured on contact wire or on wire oscillation suppressor. Said insulator is located near upper end of cable. Elastic element is installed lower than insulator. Lower end of working cable is connected to disk with holes, made according to definite order, by means of crank fitted in one of holes depending on chosen amplitude of oscillations. Disk is rigidly secured on shaft of reduction gear connected with electric motor which is connected to supply circuit through voltage regulator. Elastic element can be made in form of spring. Line autotransformer can be used as voltage regulator.
EFFECT: provision of effective adjustment of suppressors in span with resulting effective suppression of self-sustained oscillations of contact system even excluding them in separate cases, reduced time and labor input.
