<p>The invention relates to electrical equipment for overhead contact systems of vehicles with electric traction. The device comprises a base adapted for securing to supports of the overhead trolleybus contact system by means of anchoring cables, a means, arranged on the base, for switching the direction of movement of the current collectors of the trolleybus, a drive arranged on the base and connected to the switching means, and insulators arranged between the device elements. The switching means has two positions corresponding to the two branching directions of the overhead contact system, and the base has an element for limiting the movement of the switching means. The switching means is in the form of a rotatable platform which is connected to the drive and on which two pairs of guides for the current collectors of the trolleybus are arranged. The device additionally has a shaft which is arranged on the base or on the rotatable platform and ensures an angular movement of the rotatable platform relative to the base, with the two current collectors of the trolleybus being able to pass simultaneously along said shaft. The rotatable platform is made from nonconducting material. The technical result consists in increasing the reliability of the device for directing the movement of the current collectors of the trolleybus at branching points of the overhead contact system by ensuring that the switching proceeds smoothly.</p> |
