    Offset condition detecting device for detecting offset condition of pantographs from overhead contact wires by means of electric current detected by a contact element mounted on the pantograph and insulated therefrom. The detection is made electrically and in case of emergency the pantographs are lowered down at high speed to prevent damage of pantographs of trolley-assisted vehicles.

    Claim
    1. A device for recording the pantograph shift mode of transport vehicles, containing two pantographs interacting with their contact sliding plates with contact wires and equipped with a drive for raising and lowering the pantographs, characterized in that, in order to increase reliability and increase the service life, it is equipped with an edge located each pantograph contact element re5
    1620044.
    recording the pantograph shift mode from the contact wire, isolated from the contact sliding plate, current-limiting elements, current transformers with comparators, the output of each of which is connected to the corresponding pantograph lifting and lowering drive, each contact element of registering the pantograph shift mode from the contact wire is electrically connected to the contact a sliding plate of another pantograph through a current-limiting element and a current transformer.
    [2]
    2. The device according to p.], Which includes the fact that the contact element for registering the pantograph shift mode from the contact drive is isolated from the pantograph in the absence of contact between the sliding plate and the contact wire,
    [3]
    3. The device pop. 2, characterized in that the contact element for recording the bias mode, the pantograph from the contact wire is made of rubber with an electrical conductivity of 1 variable, depending on the applied pressure.
